It is vital for people in Charleston, SC. to be able to turn to a reliable HVAC company if anything goes wrong. During an emergency, they turn to Carney & Son 72 Degrees Air Conditioning and Heating, the best and most professional HVAC company in town.

Unlike many HVAC Companies, we have technicians ready twenty-four hours a day and every day to answer your call. Carney & Son is your one-stop destination if you need an HVAC company even if it is on a holiday!

Signs That You Need the Services of an HVAC company

Having your HVAC unit regularly serviced by one of our highly trained technicians is strongly recommended by Carney & Son.

This should be carried out at least once a year, as it will help prevent unforeseen problems before they arise. It will also ensure that your HVAC is working safely and more efficiently so reducing your energy bills.

HVAC units are normally very robust, but occasionally they break down requiring an HVAC company to repair them. But there are some warning signs that you should look out for to avoid this.

Coolant Is Leaking

Every HVAC unit needs an optimum level of coolant. Less coolant will mean less cooling and you will notice less cold air coming from your unit and frost and ice starting to form on the evaporator coil. The other components in your HVAC will now have to work harder to keep you cool, and so cause greater wear and tear, reducing the working life of your unit and increasing your energy bills.

Frozen Evaporator Coil

Frost and ice can also form on the evaporator coil if there is not enough airflow over it. If you ignore this sign, then the coil can freeze meaning that you will need to turn the HVAC and allow it to thaw. Again, other components will start to work harder, maybe overheating and burning out, needing a visit from an HVAC company.

Dirty air filters and blocked air return grills will also reduce the airflow over the evaporator coil. A dirty air filter will need to be replaced and the air grilles cleaned. Not only will the airflow improve but so will the air quality in your home as less dirt and pollen will enter.

The evaporator coil will need cleaning periodically too. Dirt will build up over time and act as an insulating material, reducing the heat transfer between the warm air and coil. Regular service from Carney & Son will help prevent these problems.

Dirty Condenser and Cooling Fins

The condenser and cooling fins also need plenty of air to flow over them to radiate the excess heat from your home to the outside air. As they are located outside, they will get coated with a layer of dirt and grime. This layer reduces the transfer of heat to the outside air and will result in the condenser having to work harder and may cause it to overheat and burn out. Regular cleaning is a good idea, so is removing any moss and weeds from around the condenser and fins. This is a job you can do yourself avoiding the need for a visit from an HVAC company.

Damaged Air Ducts

It has been estimated that up to 30 percent of an HVAC’s energy is wasted by cool/warm air escaping through gaps in damaged ducts. So, a regular inspection of the ducts can save you a lot of money.

How Old Is Your HVAC Unit?

The old saying that “nothing lasts forever” applies to HVAC units. Most HVAC units will need replacing after 10 to 15 years. A new HVAC will not be cheap but will pay for itself over time because they are more energy-efficient than older models, saving you on costly energy bills. As time goes by it will become harder and harder to find replacement parts especially if the model is no longer made. Older models may still be using Freon (R22) as coolant. Chemical manufacturers are not allowed to produce new R22 coolants, and only recovered or recycled R22 can be used and will mean obtaining Freon will also become more difficult and expensive.

Problems with the Furnace

The furnace is the largest component in your HVAC system and has a fan that draws fresh air from the outside into a combustion chamber. In the chamber, it is mixed with gas or other fuel, burns, and releases heat.

If gas is used, then the air vents to the outside need to be checked frequently to ensure they are not blocked. Fresh air is needed for the combustion, and any exhaust gases produced also need to be removed outside. A furnace also needs a filter to remove pollutants, and this will need regular changing.

Air Conditioning And Heating Service: What You Need To Know About Heating And Air Conditioning Units | Charleston, SC

According to the U.S. Department of Housing and Urban Development, 84 percent of all homes in the United States have some air conditioning. We live in the modern age of technology, where everything has been created for our convenience and comfort. As a result, our homes, offices, shops, and other places where we spend much of our time are fitted with heating, ventilation, and air conditioning systems, commonly known as HVAC systems. These unique temperature-controlled systems create comfortable working and living environments and are serviced by an air conditioning and heating service.

What Are the Components of an HVAC System?

An HVAC system is one of the most complicated and sophisticated systems you can have in your home or working places. As such, should a breakdown occur, only an experienced and certified air conditioning and heating service maintenance company like Carney & Son 72 Degrees Heating & AC service should handle its inspection, maintenance, and repairs. Some of the parts prone to wear and tear and which may need routine replacement and maintenance include:

Air Return

This is the starting point of the ventilation system of the HVAC system. It sucks the air, draws it through a filter before it passes it into the central system. Ensure that you or an air conditioning and heating service dusts the air return regularly since the debris and dust that piles up over time can quickly build up on your filters and cause massive damage.

The Filter

The filter is the second part of the air return unit. Filters need routine replacement to guarantee optimal performance. Depending on the manufacturer’s manual, have the filters changed by a professional air conditioning and heating service as regularly as possible.

The Ducts

These are the channels that provide the passage of heated or cooled air. It is recommended that you have an air conditioning and heating service professional clean your ducts every two years to sustain a good working condition of your heating and air conditioning system.

The Exhaust Outlets

An exhaust vent in the system expels all the utilized air. Ensure that you consult an air conditioning and heating service to check on your vent stack or chimney flue at least once a year and tune it up when necessary.

Electrical Fittings

This part ensures your system is supplied with adequate amounts of power for uninterrupted performance. Problems associated with heating and air conditioning systems often originate here. If your system stops working, check for expired batteries in your thermostat or a tripped breaker.

Outdoor Unit

This is the main part of the system you are likely to consider when an HVAC system is mentioned. It holds the fan, which aids airflow. Always ensure that you keep your unit clear of vegetation and debris since it can cause severe problems if your fan sucks in.


Being part of the outdoor unit, the compressor is capable of transforming refrigerant from gas to fluid before sending it to the coils. Therefore, inspect your compressor regularly since many system malfunctions originate from this point.


The coil is another integral part of the outdoor unit, which chills the air as it flows through. Inspect the coil frequently to ensure it is in good working condition. If you realize they are freezing up, you should adjust refrigerant levels and the filter.


The blower pulls in warm air through the central section of the unit. Ensure the air progresses through this part efficiently to enhance the durability of your heating and air conditioning system.

What Are the Most Common Problems that Occur in HVAC Systems?

Owing to their structural complexity, heating and air conditioning systems harbor particular problems that may occur in their lifetime. Most of these problems can be resolved by our highly trained and experienced professionals at Carney & Son 72 Degrees heating and AC service. The following are some of the most common issues that tend to occur in the heating and air conditioning systems:

Filter Blockage

Filters can get clogged because of the dirt that accumulates after several months of usage. When this problem occurs, filters need to be cleaned or changed for your system to work optimally.

Faulty Thermostats

This is a major problem that you should be prepared to face if you have a heating and AC system at your home or office. A thermostat is regarded as the heart of the system. If the thermostat has an issue, then the whole operation of the HVAC system is entirely stalled.

If your thermostat is an older version, then you should think of replacing it with a new digital one. If you have a modern digital thermostat and that still fails to function as intended, check if batteries have become weak and replace them. If this malfunction persists, then there might be a different problem that requires a professional’s touch. Call Carney & Son 72 Degrees heating and AC service to fix the problem.

Clogged Drain

Each heating and air conditioning system has a drainage system with a drain pan that collects the excess moisture drained out by a drain pipe. With time, this drainage system is blocked by dirt and impurities. If this blockage is not addressed early enough, the drain can expel the moisture on undesired areas of the unit and jeopardize its functioning.

Leakage of the Refrigerant

The refrigerant is a liquid that cools the air in the system to provide cool temperatures. The refrigerant may produce a leakage characterized by a sharp pungent smell. This leakage can damage other sensitive parts of the HVAC unit. Turn off your heating and air conditioning system as soon as you notice this leakage and consult a skilled air conditioning and heating service.

Failure of the Furnace to Heat up

The furnace is the primary heat-generating source of the heating and air conditioning system often fails to heat up. If this occurs, the entire room lacks heat, causing a freezing temperature. Sometimes the furnace fails to heat up as a result of the pilot light being off. If you cannot easily detect the cause of the failure, call Carney & Son 72 Degrees Heating & AC service for professional help with your air conditioning and heating service needs.

Creaking Noises

The HVAC system experiencing mechanical hitches produces weird sounds when it is turned on. The blower fan or any other structural component of the system could be faulty. To avoid further mechanical problems, act swiftly and engage a professional from Carney & Son 72 Degrees heating and AC service to fix it for you.

Settling on an HVAC company that offers the best heating and AC service is vital in enhancing the durability of your heating and air conditioning system. Carney & Son 72 Degrees Air Conditioning & Heating is a locally owned air conditioning and heating service company located in Charleston, SC. We provide heating and air conditioning expertise to both our residential and commercial customers in Charleston and its neighborhoods.

Seven Warning Signs Showing That You Need Heating And AC Service | Charleston, SC

The heating, ventilation and air conditioning system, popularly known as HVAC, is one of the essential systems in your home. HVAC systems ensure that you and your loved ones are comfortable in your home any time of the day or night. And a heating and AC service helps keep this system running smoothly.

If you are Charleston, SC resident, then you are used to the different seasons. Having an efficient HVAC system guarantees you comfort despite the season. The air conditioner in the HVAC system is essential in controlling the temperature in your home. Therefore, you will not be vulnerable to the prevailing weather conditions.

Once you purchase an HVAC system and have it correctly installed in your home, you would expect it to function efficiently for a long time with no mishap. However, some HVAC systems often don’t remember to maintain or get heating and AC service. They only remember to repair it when a serious issue/malfunction deprives them of their comfort.

It is imperative to be proactive so that your HVAC system serves you longer. Did you know that there are pointers that can help you sort HVAC issues fast? Knowing and detecting your system will enable you to solve problems by getting heating and AC service. In addition, prompt repair services save you a lot of money.

You will also be able to reach out to your professional heating and AC service and repair company in time for a quick fix to prevent future problems. So, watch out for these warning signs, and do not hesitate to call a professional HVAC Repair and Maintenance Company.

1. Thermostat Problems

A thermostat is a critical component that makes up the heating, ventilation and air conditioning system. In your home, it helps regulate temperature, enabling you to adjust the air conditioner to your preferences. Unfortunately, your thermostat shows signs of malfunctioning by failing to adjust the temperature to the required level, despite turning the knob.

You will notice this when you find that your home is warmer or cooler than usual despite having set your thermostat correctly. Another sign of letting you know that your thermostat has an issue is when the air conditioner fails to shut off, recording incorrect temperature readings.

When you notice these signs, you need to get in touch with your trusted HVAC Repair Professional Company to check for the malfunction’s reasons immediately. Please don’t try DIY hacks with thermostats. You need heating and AC service professionals.

Trying to fix it yourself is not a brilliant idea since the thermostat requires a highly trained professional who knows the workings of this component. The expert will then advise you appropriately. In addition, the thermostat may be old needing replacement, or there might be some other issues that a quick fix will see it working.

2. Refrigerant/Pilot Light issues

When the refrigerant doesn’t perform optimally or fails to perform all together, this should be a warning sign. It may be a warning sign that your HVAC system needs to be repaired by a heating and AC service. The pilot light malfunction can escalate the problem. When this happens, it may cause the burner to fail to heat the system.

Strangely, when the refrigerant malfunctions, the air conditioner may also fail to regulate the temperature of your home. If you take note of such problems, it is necessary to call a professional in Charleston, SC, to fix those issues before they force you to incur a lot of money in further repairs.

3. Unpleasant Smell coming out of your HVAC System

Nothing makes your room uncomfortable than having foul odors coming from your home. A bad smell from the HVAC may be caused by the malfunctioning of several HVAC system components. Eliminating bad smells in your home should be done promptly to protect your loved ones from getting sick.

Immediate action will also help correct malfunctioning of numerous parts of the HVAC system, such as the heating and AC service. Contacting a professional with experience in HVAC maintenance will help solve the issue promptly.

4. Incurring High utility bills than usual

If you notice that you are paying excessive amounts (than previously experienced) to run your HVAC system, be worried. This indicates that your system may be having some inefficiencies. When your energy bills suddenly escalate at an alarming rate despite you using your usual electronics, then this is a warning that your system might have slowed down.

To address this situation, you need to call your trusted heating and AC service company to investigate the cause of the inefficiencies.

5. Noise coming from the HVAC system

Even when your system is working perfectly, but you hear some noise originating from the HVAC system, you should know that something is wrong and a heating and AC service should be called. A well-maintained system does not produce any noise, which makes your home comfortable and peaceful.

Odd noise coming from the HVAC system indicates that the connection may be faulty, or some components may have malfunctioned. Consulting a professional in HVAC will enable you to solve the issues which may save you a lot of money in the long run.

6. Leaks from your Air conditioner

Components of the HVAC system sometimes depend on other components to function correctly. For example, the refrigerant functions influence the working of the air conditioner. As a result, condensation may occur as the air conditioner operates, but the liquid should not leak into other parts of the HVAC system.

When you take note of water leakage from the air conditioner, this is a warning that your system may be experiencing problems. Contacting your professional HVAC Company will help look into the matter and solve some problems that may cause loss of money.

7. Issues with your duct system of HVAC

Ducts form an integral component of the heating, ventilation, and air conditioning system. Therefore, when you notice a significant difference in temperature among your various rooms, you should know that the ducts may be having an issue.

7 Signs It Is Time To Call An HVAC Company | Charleston, SC

The HVAC system in your Charleston, SC home is essential to your daily life. If it isn’t functioning properly, your home will be very uncomfortable. You rely on your HVAC system to keep your home warm during the winter and cool during the summer. The last thing you want is a complete HVAC system breakdown when you need it the most. The best way to prevent a complete breakdown is to recognize the early signs that you need to call an HVAC company. If you can detect the signs early, you can prevent a minor issue from becoming a major one.

#1 The System Isn’t Producing Cool or Heated Air

This is the most obvious sign that you need to call an HVAC company, and it should not be ignored. Before you make the call, turn your system on full blast and stand under the vents. If you feel cool or heated air, you are all set.

If the temperature in your home doesn’t change after a few minutes, you will need to call a licensed company. There are a few issues that could be causing the problem:

  • A leak in the refrigerant line
  • A malfunctioning compressor
  • A short in the electrical connections

It is best to call an HVAC company right away to prevent the issue from getting worse.

#2 Insufficient Airflow

If you aren’t getting adequate airflow from the vents in your home, your home won’t reach the desired temperature. Your system will try by working overtime, which can cause an increase in your energy bills. It can also reduce your HVAC system’s lifespan.

There are a couple of issues that can cause poor airflow:

  • A broken motor
  • Clogged air filter
  • Clogged air ducts

It is essential that you call an AC company as soon as you realize that you have inadequate airflow.

#3 Strange Sounds Coming From the Unit

When your HVAC system is functioning properly, you shouldn’t hear anything more than a quiet clicking when the system kicks on and off. If you hear anything more, such as squealing, squeaking, grinding, or any other strange sounds, you should call an HVAC company. There could be a broken or loose part rattling around in the system, which can cause further damage. Even if your HVAC system is still functioning properly, you should still schedule an appointment with an HVAC service right away.

#4 Frequent Cycling

It is normal for the HVAC system in your Charleston, SC home to cycle frequently. When it is very hot or very cold outside, it will cycle more often; however, it should not cycle constantly. If you notice frequent cycling, you should schedule an appointment with an HVAC service right away.

The issue could be that your system needs a tune-up, which is a relatively simple fix. This could also be a sign that your HVAC system has reached the end of its lifespan and needs to be replaced.

It would take the knowledge and experience of an HVAC company to determine the source of the problem to resolve the issue accordingly.

#5 Foul Odors Coming From the HVAC System

If the air coming from the vents in your Charleston, SC home smells musty or moldy, you should schedule an appointment with an HVAC company. This can be due to mold build-up in the air ducts or in the HVAC system itself. This is a very serious issue. It is very dangerous for your family to breathe in mold spores. This can cause allergy symptoms. If a member of your family has a chronic respiratory illness, breathing in mold spores can make their condition worse.

An HVAC company can find the location of the mold and remove it.

If you smell a burning smell, you should turn your HVAC system off immediately and call an HVAC service. There could be an electrical short that can cause a devastating electrical fire.

#6 A Frozen Or Leaking Unit

If there are any leaks, puddles, or ice around your HVAC system, you should call an HVAC professional immediately. The issue could be a block in the condensation line, causing the condensation to freeze on the coils. When the ice melts, it will puddle around the ground.

You could also have a refrigerant leak, which will affect the way your system performs.

It is best to call an HVAC professional as soon as you notice the problem.

#7 Energy Bills That Are Higher Than Normal

If you notice that your energy bills are higher than normal, your HVAC system could be to blame. If your system isn’t operating as efficiently as possible, it will need to work overtime to keep your home comfortable.

This issue could require a tune-up, which is a relatively simple fix. It could also be an issue with the mechanical components, or the system may have reached its maximum lifespan.

You will need the assistance of an HVAC company to figure out what is causing the problem so the issue can be resolved.

10 Heating And AC Service Signs It’s Time To Upgrade Your HVAC Unit | Charleston, SC

Is your HVAC system producing odd noises when running? Your HVAC system may not be working as well as it used to, and your bills reflect it. You may have probably moved into a home with an older heating and cooling system, and you aren’t sure of its history. There are many signs that you need an upgraded HVAC unit.

In this piece, we discuss ten signs that it is time to upgrade your HVAC unit.

Temperature difference in your home

If different rooms in your home feel too hot or too cold, your HVAC system isn’t running correctly and needs to be replaced. A properly functioning heating and cooling system should maintain regulated temperatures throughout the house. Damaged or clogged air ducts are often the culprit when there is a temperature variation across your home. Your HVAC system may also be too small to condition the air in every room adequately. An upgraded HVAC system from a reliable heating and AC service in Charleston, SC, will ensure your home receives adequate air conditioning.

Your system makes unusual noises

Loud noises emanating from your heating and cooling system aren’t normal. If you need to shout to be heard in your own home, something is definitely wrong with your HVAC unit. When parts of your system wear out or become loose, noises are produced. When these noises become too loud and frequent, it is a sign that the HVAC system is a good candidate for replacement. Consult a heating and AC company on whether your unit needs repairs or replacement.

Your HVAC system is old

Usually, a well-maintained heating and AC unit has a lifespan of up to 15 years. As it ages, it becomes less effective and utilizes more energy. Changes that occur in our indoor environments introduce new stressors that cause detriment to HVAC systems. From new building practices to new cleaning supplies, they all play a role in the overall decline in the performance of a heating and cooling system. If your system has been running for over ten years, it may be time to consider consulting a heating and AC service to replace it with a newer and more efficient model.

Constant repairs

Are you spending money on constant repairs on your HVAC system? You are better off upgrading your system instead of constantly spending money on regular repairs to maintain the old unit. Frequent repairs are a classic tell-tale sign that your unit is wearing out and may soon stop working altogether. Save yourself from frequent expensive repairs by having a professional heating and AC service replace the worn-out unit.

Your energy bills are rising

No one wants to spend more money on their energy bills. If your energy bills are rising yet there are no changes to your heating and cooling demands, your unit is ineffective. Often than not, it may mean you need to change your filters and clean your ducts. However, coupled with other issues such as age, it may be time to upgrade your heating and AC unit. Get in touch with Carney & Son heating and AC service to carry out maintenance and help determine if it is time to upgrade.

Deteriorating air quality

As your heating and cooling system gets older, it will start to accumulate allergens, dust, and air pollutants. This, in effect, reduces the air quality you receive in your home and, in extreme cases, even causes allergies and respiratory conditions. If a heating and AC service replaces your old filters and the air quality doesn’t improve, it is a sign that you need a new air conditioning system. A new HVAC system will help improve the air quality and protect your loved ones from respiratory ailments.

Your heating and cooling system isn’t smart

Is your heating and cooling system smart? A smart HVAC system has advanced features such as Wifi and a programmable thermostat. It helps you save money in the long run and introduces convenience. Once installed by a heating and AC service, the system allows you to manage it when you aren’t at home, enabling you to save energy and money. The initial installation cost may seem high, but the energy savings, cost savings, and convenience are definitely worth it.

Your HVAC frequently turns on and off

If your HVAC system constantly shifts between on and off modes, it may need to be repaired or too large for your home. Constantly turning on and off causes your HVAC system to wear out quicker as it is running more frequently than often. This leads to premature damage to the system’s parts. It is advisable to contact a heating and AC service around Charleston, SC, to check whether your HVAC unit is the wrong size and in need of replacing to suit your needs and the size of your home.

Your home feels too humid

One of the main tasks of an air conditioner is to regulate humidity in your space. It is one of the reasons your space feels more comfortable. However, when your HVAC is struggling to operate, it may leave your space feeling clammy because it can’t dehumidify effectively. Problems with humidity may also arise from having an HVAC system that is too large for your space. It is essential to have a heating and AC service check your system to determine the problem.

Your circuit breaker keeps tripping

When a circuit breaker trips once or twice, there is no cause for concern. However, if you are repeatedly battling the circuit breaker, you may have a problem with the HVAC system. A circuit breaker that keeps tripping is a tell-tale sign that you need to replace your HVAC system. After contacting a heating and AC service to repair it, have them inspect the HVAC unit to know if it is time for an upgrade.

Finding The Right HVAC Company For Your Home | Charleston, SC

Why is finding the right HVAC company more important in the summer months? During the hot sunny season of the year, the air is humid, and people are subject to upper respiratory infections, allergies, and heat exhaustion. With the weather being such as it is during this time of the year, keeping cool becomes a priority.

Chances are you might hear or observe strange noises or feel a change in your environment. These signs are usually sure to tell signs that something is wrong with your unit, and our HVAC company is the one to call.. Although it is normal for a cooling and heating unit to make some small sounds, loud noises are usually not common. Sounds can tell a lot about what is going on. Nevertheless, we still will not make a diagnosis without properly, and thoroughly, checking out your unit. Therefore, if your unit is experiencing any of these problems, your system needs to be serviced as soon as possible. Now is the time to contact our HVAC company and ask for help.

  • Blowing hot air
  • Not circulating
  • Not cooling the room
  • Making unusual noises
  • Constantly leaking

These are just a few noticeable issues. Not providing interval maintenance on your unit can increase your energy bill. When your heating or cooling unit is not cooling or heating as it should, the internal parts try to compensate for the insufficiency; therefore, causing the unit to work harder. The harder your unit works the more power it pulls, and the higher your energy bill. However, you can avoid spending money unnecessarily, if you call the right people to do the best job.

What Happens If I Ignore a Problem with My Heating and Cooling Unit?

Ignoring an existing problem is a costly mistake. When damaged units are not maintained they tend to cost more to repair. This is due to other elements or parts becoming affected by the malfunction. If problems are caught early, you can save yourself some serious money. There are lots of heating and cooling companies around Charleston, SC. However, not all of them provide excellent service, nor do they repair all makes and models. Why spend money on heating and cooling companies that do not provide the services you need? Give our HVAC company a chance to make you a satisfied customer.

How Do We Find the Problem?

We do not give you a quote until we have performed a thorough inspection of your unit. We have no idea what is wrong with your system until we perform an inspection of your unit.

Once you know which direction to go in, you can then decide on how much money you want to spend.

Most heating and cooling companies do not use the same approach to find the problem. Some may take a shortcut, or insist they know what the problem is before performing an actual inspection. Stay away from companies that want to give you a quick quote without going through the right steps.

Air Conditioning And Heating Service: How To Tell When It’s Time to Replace Your Air Conditioner | Charleston, SC

For any Charleston, SC homeowner it is a tough decision on when to replace your air conditioner. In fact, due to the high cost of an AC unit, it is one of the toughest decisions you will face as a homeowner. A new air conditioner is a huge investment. Homeowners must decide whether or not to keep repairing older inefficient AC units or to replace them with a newer more energy-efficient model. Today’s Air Conditioning and Heating service companies offer an array of high-efficiency models.

Deciding when to replace your air conditioner is not an easy task. Carney & Son 72 Degrees Air Conditioning and Heating of Charleston, SC has you covered with this advice on when it might be time to call an HVAC service for air conditioner replacement. Below are some of the most tell-tale signs that you need a new air conditioner.

Your Air Conditioner Is More Than 10 Years Old

Most air conditioning units were designed to last ten to twelve years. That is only if they are well maintained with AC tune-ups every year and well cared for. Units that do not see regular maintenance will not last as long. It is vital that you do tune-ups every year on your air conditioning unit if you want to see the full life span of your unit. Some well-maintained units can last longer than twelve years but this is not the norm. If your air conditioner is needing constant repairs and your unit is ten-plus years old, it might be time to call Carney & Son 72 Degrees Air Conditioning and Heating for a new unit. This is even more true when you consider the advancements in energy efficiency in the last five years alone with central air conditioners. Older unit parts are more costly to replace than newer units is another factor to consider here with an aging unit.

Your Air Conditioner Uses Freon

If your air conditioner uses Freon, chances are it is using R-22 Freon. R-22 Freon production has been phased out by the United States federal government as of January 1st, 2020. You can still have Freon added to your air conditioner when needed, but it is now extremely costly to do so. Add on to that the cost of repairs and you might well have your answer about when it’s time to make that call to an Air conditioning and heating service. If your older AC unit uses freon you will eventually need to replace it with a unit that uses the newer R410A refrigerant. You can even use a Heat Pump to go even greener. Despite the name Heat Pump, it actually will cool your home. Basically, if your unit still uses Freon it is time to consider making that call to an air conditioning and heating service for a new unit replacement.

Your Air Conditioner Is Energy Inefficient

If your air conditioner has a low SEER Rating it will cost you a lot of money to operate every year. The SEER rating, also known as the seasonal energy efficiency ratio, has a minimum standard SEER rating of 13 for AC units. The maximum efficiency for AC units is a SEER of 21 SEER. The size of your AC unit along with the size of your home will also determine the efficiency of your system. Your ductwork even comes into play for the efficiency of your system. If your air conditioner’s SEER rating is below 14 you are paying a lot of extra money to the utility company every year just running your AC unit. We recommend that our customers seek out SEER 20 or 21 models for maximum energy efficiency. If your AC unit has a SEER of 13 or below it is not an energy-efficient model and should be replaced with a newer model. You can always call your local Air conditioning and heating service if you are unsure of your unit’s SEER rating.

Extensive and Expensive Repairs

If your air conditioner is facing a rather expensive repair, you might consider making that call to an Air conditioning and heating service such as Carney & Son 72 Degrees Air Conditioning and Heating. Simply weigh the costs of the heavy repairs against the cost of a new unit. Also factor in the current unit cost per year to operate based on its maximum efficiency. Keep in mind its maximum efficiency will only be at its maximum if you provide yearly maintenance such as an AC tune-up every year. Now weigh the two costs together and determine what the best path forward for you is. If you have multiple signs on this list of tell-tale signs then it is definitely time to make that call to an air conditioning and heating service.

Frequent Breakdowns

Is your air conditioner breaking down often? Are you constantly calling up an Air conditioning and heating service to make expensive air conditioner repairs? Are you calling Carney & Son 72 Degrees Air Conditioning and Heating to often address ever-mounting problems with your air conditioner? Repair costs will quickly add up, so if you are experiencing frequent AC repairs, it might be more worth your money to invest in a new air conditioner. You might save money in the long run by simply replacing the old unit with a high-energy efficient unit.

Your Home Is No Longer Comfortable

Does it seem as if you can never keep your home cool anymore? Your AC may be failing and only a matter of time before it breaks down completely. There is also the chance that your air conditioner size is the wrong size for your home and ductwork. You need your AC unit to do its job and cool down the house. If your air conditioner is no longer cooling the home it may be time to make the call to an Air conditioning and heating service in Charleston, SC such as Carney & Son 72 Degrees Air Conditioning and Heating service.

If you have any of the signs on this list you may want to consider investing in a new AC system. Carney & Son 72 Degrees Air Conditioning and Heating can replace your aging AC unit with ease. Call us today for a quote.

When Is The Ideal Time To Have Heating And AC Service And Maintenance? | Charleston, SC

Not many homeowners in Charleston, SC give a second thought to maintenance for their air conditioner or heating system. We all see the advertisements from Heating and AC Service companies suggesting a tune-up and inspection of your air conditioner or heating system. Yet a lot of people skip this very necessary vital step in maintaining their HVAC system. Many people ignore their HVAC system altogether until something goes seriously wrong with the cooling or heating system, such as not getting any cold air in the summer or no hot air in the winter. It is often only when something goes wrong that people call for service.

Just like your car or truck, your heating system and air conditioner also need routine maintenance. In fact, HVAC maintenance is vital to having a functioning heating system or air conditioner, free of major malfunctions. Did you know that having a tune-up of your heating system and air conditioner every year helps to prolong its life? It also helps you avoid major repairs by catching minor problems before they spiral out of control and become major problems such as expensive parts replacement from a Heating and AC Service company.

What exactly does heating system and air conditioner maintenance entail? Well, the level of service for one will vary from company to company. Carney & Son 72 Degrees Air Conditioning and Heating offers full Heating and AC Service without cutting any corners. Our HVAC technicians will perform an inspection of your HVAC system. During this inspection, they will test vital components of your system, clean anything dirty and adjust anything that needs an adjustment. They will also be on the lookout for minor problems which if left unattended could become a major repair down the line. Oftentimes a simple part might need replacement due to wear and tear on your heating and cooling system.

Our professional HVAC service is also on the lookout for any adjustments that will help to improve your heating or air conditioner’s performance and efficiency. The more efficient your system runs, the cheaper your utility bills will be. This of course saves you money over the long term. Not only does regular yearly maintenance prevent future problems, but it can also save you money over time, depending on what your technician does and finds with your system. While most issues can be caught while they are minor issues there is a slight chance we may find a major fault, such as failing components in your system. In this case, you might need to schedule an appointment for the replacement of major components, depending on if we have the parts on hand or not. We can locate most parts rather quickly.

Now that we know how important it is to have regular heating and air conditioner maintenance for your systems, the question now becomes when do you schedule this maintenance service? The answer is a simple one: before you need it. Let me explain here, you do not want to schedule maintenance for your heater in the wintertime, nor do you want to schedule maintenance for your AC unit in the summer. You should call your Heating and AC Service during the off seasons for maintenance. So for your heating system the ideal time of the year to service it is in the fall, while for an AC unit the ideal time would be in the spring. Why is this you ask? Simple, you want to catch problems before you need the heater or AC unit in question operating. You also will find it easier to get ahold of an HVAC service technician during the off months as these professionals will not be as likely to be busy. Summer and winter are the busy months of the year for any Charleston, SC Heating and AC Service company.

The next question you should be asking yourself is how often you should schedule maintenance for your AC unit and heating system. Each system should be seen by a professional Heating and AC Service company once a year. If you have an AC unit or a furnace you should have them inspected and tuned up once per year. You should ideally call in the off-season when it is easier to schedule maintenance at your leisure, plus when more Heating and AC Service professionals are available. By taking care of your maintenance early you avoid problems when you most need your AC unit or heater running.

You should schedule maintenance for your own peace of mind and comfort. What do we mean by comfort? Well for one thing heating and air conditioning systems degrade over time. This is especially true of climate control systems. Climate control systems over the years start to perform less efficiently. Our Heating and AC Service professionals can detect when these systems are failing and repair or replace them, leading to greater comfort in the home. There’s also the possibility of less of a utility bill in many cases.

Regular maintenance of your AC unit and heating system also helps to keep you and your loved ones safe. If you have a natural gas-powered heating system then this is especially true in your case. You could unwittingly be exposed to high levels of carbon monoxide gas. There are also fire hazards with older systems that may have damaged parts such as a faulty heat exchanger. Regular maintenance when done will alert you to any hazards your systems may pose. It is cheaper, in the long run, to catch problems early on than to wait for these problems to not only grow but spiral out of control.

If you have not yet scheduled your HVAC maintenance, now is the time while you still remember to do it. Call the most professional Heating and AC Service in Charleston, SC, Carney & Son 72 Degrees Air Conditioning and Heating, today to schedule your HVAC maintenance. Our friendly service reps will schedule an appointment that works for you at your convenience.

Tips For Keeping Your Air Conditioning Cool With An HVAC Company | Charleston, SC

Did you know that air conditioners and HVAC systems need to be maintained by a professional HVAC company over the course of their lifetime?

Most experts recommend having an HVAC company maintain your HVAC system twice a year: once in the spring before most houses use cooling and once in the fall before most houses need heating. This applies if you have one unit that cools and heats the home, or if you have two separate units (an air conditioner and a furnace).

In Charleston, SC, one HVAC company offers regular service maintenance that includes cleaning and checking your HVAC systems to keep it working year-round: Carney & Son 72 Degrees Air Conditioning and Heating. Their team’s regular maintenance allows an expert to spot small issues before they spiral out of control, cause damage, and threaten your heating and cooling right when you need it most.

Their checklist for spring and summer maintenance includes:

  • Replace all filters.
  • Clean evaporator coils and condensers.
  • Clear clogs and clean drain lines to ensure proper flow.
  • Remove any standing water from drain pans to avoid overflows.
  • Replace worn pulleys and belts.
  • Inspect ducts for dust, mold, or debris.
  • Check the refrigerant charge and for any possible leaks.
  • Check thermostats and their controls to ensure they are correctly set.
  • If necessary, change batteries.
  • Check all connections and the electrical system.
  • Make sure the fan motor is operating correctly.
  • Inspect the blowers and blades to maintain proper airflow.
  • Lubricate any moving parts.
  • Check the HVAC cabinet for leaks.
  • Make sure the HVAC cabinet door is securely closed.
  • Remove any debris from around the unit if it is outdoors.

Their checklist for fall and winter maintenance includes:

  • Replace filters every 30 to 90 days.
  • Check the ignition burner assembly.
  • Carefully inspect heating elements or heat exchangers. If these get damaged, they could lead to problems with carbon monoxide.
  • Inspect the flue system and make sure it is securely attached to the furnace.
  • If you own a gas furnace, the technician will check for gas leaks.
  • It’s also essential to check for gas pressure.
  • Replace frayed belts and pulleys.
  • Clear drain lines and pans of standing water to prevent overflows.
  • Check wiring and electrical connections.
  • Lubricate all moving parts such as bearings and motors.
  • Check thermostats and controls to ensure they are set at the right temperatures.
  • Check the heat pump.

Based on your system’s needs, an HVAC expert from Carney & Son 72 Degrees Air Conditioning and Heating will weigh in on the preventative maintenance you need.

Don’t Dodge Your Ducts And Vents

Even in beautiful Charleston, SC, you’ll want to make sure that your heating and air conditioning systems are in top shape and you have the number handy for an HVAC company.

These systems also include a series of ducts and vents that push and pull air within your house, which are responsible for keeping all rooms properly and evenly cooled and warm. If the ducts are damaged or filled with debris, airflow in your home will not be circulating correctly, leaving you with a system that is not energy efficient and potentially causing you and your family respiratory and health issues with allergen and dust build-up.

Regular duct servicing and cleaning can extend the life and efficiency of your HVAC system, and luckily, local HVAC company Carney & Son 72 Degrees Air Conditioning and Heating are devoted to keeping your air ducts clean and dust-free.
