‘Why Is My Mini-Split Leaking Water?’ & Other Ductless Air-Con Issues!

Ductless air-conditioning, or mini-splits, is becoming more and more popular. They’re efficient, quiet, and can be installed almost anywhere. But like any other piece of machinery, they’re not perfect. If you’re having issues with your mini-split, you’re not alone.

This blog post by Carney & Son 72 Degrees will explore some of the most common ductless AC problems and their solutions. Stay cool!

Issue #01: My Mini-Split is Leaking Water

If your mini-split leaks water, it’s likely due to one of two issues: either the drain pan is full, or the condensate pump is not working properly.


1: Empty the Drain Pan

The first thing you’ll want to do is check the drain pan. If it’s full, empty it and see if that solves the problem. If your mini-split doesn’t have a drain pan, you can purchase one at your local hardware store.

2: Check the Condensate Pump

If your mini-split has a condensate pump, ensure it’s turned on and working properly. If it’s not, you may need to replace it.

Issue #02: My Mini-Split is Making Strange Noises

If your mini-split is making strange noises, it could be due to several issues, including loose parts, debris in the fan, or a problem with the compressor.


1: Check for Loose Parts

First, make sure all the bolts and screws are tight. If that doesn’t solve the problem, you may need to call a technician to take a look.

2: Clean the Fan

If your mini-split fan is dirty or full of debris, it can cause strange noises. To clean the fan, turn off the power and remove the unit’s front panel. Then, use a brush or vacuum attachment to remove any dirt or debris.

3: Call a Technician

If you’ve tried the above solutions and the noise persists, there’s likely an issue with the compressor. In this case, you’ll need to call a technician for repairs.

Issue #03: My Mini-Split is Blowing Hot Air

If your mini-split is blowing hot air, it could be due to several mini-split issues, including clogged filters, a refrigerant leak, or a problem with the thermostat.


1: Check the Filters

If your mini-split filters are dirty or clogged, they can restrict airflow and cause the unit to blow hot air. To clean the filters, remove them from the unit and wash them with soap and water.

2: Check for a Refrigerant Leak

If your mini-split is leaking refrigerant, it will likely be blowing hot air. To check for a leak, look for an ice buildup around the copper lines that connect the indoor and outdoor units. If you see ice, there’s likely a refrigerant leak.

3: Check the Thermostat Settings

If your mini-split thermostat is too low, it may be blowing hot air. To check the thermostat settings, look for a switch near the indoor unit that says “Fan” or “Auto.” If the switch is set to “Fan,” change it to “Auto.” If the problem persists, call a technician for help.

Important Note: You can try these fixes at home but don’t go overboard. You may end up doing more harm than good. It’s best to call a professional after a few tries!

Beating The Heat – 9 Fascinating Facts About Air Conditioners!

There’s nothing as refreshing in the summer as a cold drink or an ice cream. And when the weather is really hot, what’s better than stepping into a nice, cool room?

Air conditioners help make summer temperatures more bearable and are necessary for many homes. But how extensively do you know about air conditioners?

Here are some fascinating air conditioner facts about these cool appliances by Carney & Son 72 Degrees.

Cool Facts About AC

  1. The first air conditioner wasn’t designed for comfort: They were first used in the 1800s to help prevent the spread of disease. The first air conditioner was designed by a doctor, John Gorrie, who wanted to find a way to cool patients with malaria.
  2. Movie theaters used to be the coolest: Air conditioning was first installed in movie theaters in the early 1900s. Inventors did this to help keep the film from melting in the heat!
  3. Air conditioners can save your life: Studies have shown that air conditioners can help reduce the risk of heat-related deaths during a heatwave.
  4. An AC unit uses a lot of energy: A typical central air conditioner will use 3000 to 5000 watts of electricity to run. That’s about as much as it takes to power a clothes dryer!
  5. There’s a right and wrong way to use your AC: Running your air conditioner all day long is bad for your energy bill and health.
  6. They can cause mold: If your air conditioner is not properly maintained, it can become a breeding ground for mold and mildew.
  7. They can make you sick: If you are allergic to dust or mold, you may want to reconsider using an air conditioner.
  8. They can cause global warming: Chlorofluorocarbons (CFCs) are used as a coolant in many air conditioners. When these chemicals are emitted into the atmosphere, they deplete the ozone layer, which leads to global warming.
  9. It’s best to clean your air conditioner regularly: To keep it running efficiently, it’s important to clean it regularly. Depending on your home’s air conditioner, you may need to do this yourself or hire a professional.

Is AC Maintenance a DIY Job?

In a nutshell, no, AC maintenance is not a do-it-yourself job. While you can certainly clean the filter independently, other tasks, like checking and refilling refrigerant levels, require professional training and equipment. Additionally, many newer AC units have sealed systems that prevent homeowners from accessing internal components. Trying to repair or maintain these units alone could void the warranty.

We know that maintaining your AC unit can be challenging, which is why our team of experts is here to help. Carney & Son 72 Degrees offers various AC maintenance services in the Charleston area, including filter replacement, Freon recharge, HVAC system tune-ups, and much more.

5 Environmentally Friendly Refrigerants For Using HVACs Responsibly

It’s no secret that harmful refrigerants have devastatingly affected the environment. Many businesses are now looking for environmentally friendly refrigerants to replace Freon and other harmful chemicals.

In this blog post, Carney & Son 72 Degrees will discuss some of the best environmentally friendly refrigerants on the market and how you can use them in your HVAC system responsibly!

History Of Harmful Refrigerant Effects On The Environment:

Chlorofluorocarbons, CFCs or Freon, are a group of man-made chemicals that were once commonly used in refrigerators, air conditioners, and aerosol cans. However, freons were found to damage the Earth’s ozone layer, protecting us from harmful ultraviolet rays. As a result of this discovery, the production of CFCs was banned in many countries in the late 20th century.

Hydrofluorocarbons (HFCs) or another brand of freons are a group of man-made chemicals developed to replace CFCs. While HFCs do not destroy or harm the ozone layer, they are potent greenhouse gases that trap heat in the Earth’s atmosphere and contribute to global warming.

Global Warming Potential (GWP) tool:

In response to the toxic effect, a timeline for the phase-out of chlorine-based refrigerants was established by the 1987 Montreal Protocol and subsequent accords. The Global Warming Potential (GWP) tool was created to gauge and compare how refrigerants and other compounds affect the atmosphere and consequent global warming. Rating refrigerants according to their GWP values enables harmful gases with high GWP values to be phased out while promoting those with lower GWP values as replacements.

5 Environmentally Friendly Refrigerants:

Fortunately, several environmentally friendly refrigerants can be used in place of CFCs and HFCs. These refrigerants include:

1. Hydro-fluoro olefins (HFOs):

HFOs are a type of fluorocarbon, but they do not contain chlorine or bromine and are therefore much less damaging to the environment.

Few of the HFOs include R449A and R454C.

2. Carbon dioxide (CO₂):

CO₂ is a naturally occurring gas used as a refrigerant for many years. It is non-toxic and does not contribute to ozone depletion. CO₂ is a very efficient refrigerant, but it can only be used in applications where the temperature is below 78 degrees Fahrenheit.

3. Ammonia (NH₃):

Ammonia has been a refrigerant for over 100 years and is still used today. It is very efficient and has a very low impact on the environment. Ammonia is also very inexpensive, making it a great choice for businesses looking to save money.

However, its flammability limits its widespread use.

4. Isobutane (C₄H₁₀):

Isobutane, which is stable and comparable to its predecessors in performance and environmental effect, has a very low GWP value of just 3. It is now among the most regularly used refrigerants for residential, commercial, and industrial refrigeration.

5. Isopropane:

Isopropane is evolving into a common refrigerant for commercial and industrial refrigeration and specialized applications for camping, recreational vehicles, laboratory, and medical refrigeration. It combines Isobutane and well-known, affordable, and easily accessible propane.

Several other refrigerants have low GWP values and are considered environmentally friendly. However, the two most common ones are Isobutane and isopropane. These are two great options to consider if you’re looking for a refrigerant that will not harm the environment.

Can Anyone Actually Use A Heat Pump In Summer?

A heat pump might be ideal if you’re looking for an energy-efficient way to keep your home cool during the summer. Heat pumps can be used in winter and summer, making them a versatile option for homeowners. You need to know certain things before you decide if a heat pump is right for you. This post will discuss in detail what you should know about using a heat pump in summer!

Using a Heat Pump in Summer – How Does it Work?

As the weather gets warmer, you might wonder if you can use a heat pump in summer. The answer is yes! Heat pumps can efficiently cool your home in the summer months. Here’s how it works:

It extracts heat from the air inside your home and transfers it outside. This procedure cools the air inside your home and makes it more comfortable.

Save Money with a Heat Pump in Summer

One benefit of a heat pump is that it doesn’t use as much energy as other cooling methods, such as central air conditioning. You can save a huge amount on your energy bills during summer.

In addition to saving money, using a heat pump in summer can also help improve the indoor air quality of your home. By circulating the air, the heat pump can remove pollen, dust, and other allergens from the air. This can reduce the symptoms of allergies and asthma.

Remember a Few Things

If you’re considering using a heat pump in summer, there are a few things to remember. First, it’s important to have your heat pump serviced before the start of the season. This will ensure that it’s working properly and that there are no potential problems.

Second, you’ll need to ensure that your home’s heat pump is the right size. If it’s too small, it won’t be able to cool your home effectively. However, if it’s too large, it will use more energy than necessary, increasing your utility bills.

Third, you’ll need to ensure that your heat pump is properly installed. If it’s not, it could cause problems with cooling your home.

Finally, ensure that you maintain your heat pump properly. This includes regularly changing the filters and ensuring that the coils are clean.

Follow these tips, and you should be able to use your heat pump in summer without any problems.

Using a Heat Pump in Your Bedroom

  • First, you’ll want to ensure that you keep the blinds or curtains closed during the daytime. This will help keep the sun out of the room and make it cooler.
  • You may also want to consider using a ceiling fan in your bedroom. That will circulate the air and keep the room cool.
  • Using it for a couple of hours when you go to bed will help cool down the room so that you can sleep comfortably.

If you follow these tips, you should be able to use your heat pump in your bedroom during the summer months without any problems.

4 Common AC Maintenance Mistakes Homeowners Make

Air conditioning units are a considerable investment, but the relief they offer from the blistering summer heat makes them worth the investment. However, it is essential to take care of your unit. You can expect about 20 years of use from your unit with regular air conditioner maintenance.

Unfortunately, many homeowners make mistakes with air conditioner maintenance that can lead to decreased efficiency and a shorter lifespan for their air conditioning unit.

To help you out, below are the four common air conditioner maintenance mistakes highlighted by HVAC contractors. By avoiding these, you can keep your air conditioner running without issue for years to come.

Ignoring Unusual Noises:

After spending a specific time with your air conditioning unit, you’ll become familiar with its normal operating noises. In many cases, unusual noises are an indication of a more severe issue developing within your air conditioner. For instance, shrieking noises may indicate that your air conditioner’s compressor is failing, while rattling noises may be a sign that something has come loose inside the unit.

If you ignore these noises and continue to run your air conditioner, you could end up causing severe damage to the unit – and incurring expensive repair bills as a result.

Not Changing the Air Filter:

Air conditioner maintenance isn’t just about the coils and fins outside the unit. You should regularly change the air filter. It tracks dust, pollen, and other particles that can clog the system. A dirty air filter will make your unit work harder than necessary, eventually leading to a complete system shutdown.

The rule of thumb is to change it every three months but check it monthly to be certain. All you have to do is remove the old filter and put a new one in its place. However, be careful with the sizing.

Failing to Repair Leaks:

Leaks are a prevalent problem with air conditioners. It could be a slow drip or a full-on gush, but you need to take care of it. The Freon gas that cools the air can be expensive, so you don’t want it leaking out.

Contact professional HVAC contractors immediately if you see any signs of a leak, such as a pool of water around the unit. They will be able to repair the leak and recharge your system. Please don’t attempt this yourself as you could worsen the problem.

Putting Regular Maintenance on the Backburner

Installing an air conditioner is just the beginning. You must also commit to regular air conditioning maintenance for your unit to work properly and efficiently. Examining thermostats, cleaning the condensate pump of any algae build-up, and ensuring the outdoor compressor is free of debris are all part of regular maintenance.

If you neglect these things, your air conditioner will have to work harder to do its job. It could eventually cost you more money in the long run. HVAC contractors can help you keep on top of regular maintenance so that you don’t have to worry about it.


Air conditioners are a sigh of relief during the hot days of summer. However, they can be a headache when they break down and need repair. Before you hose down your ducts in the hope of fixing the problem, take a step back.

Professional HVAC contractors like Carney & Son 72 Degrees, serving Isle of Palms, can help you troubleshoot the problem.

Whether you need help with air conditioner installation or air conditioner maintenance, our air conditioner experts are your answer.

Top Seven Qualities Of A Reliable HVAC Company | Charleston, SC

Heating, ventilation, and air conditioning system is a significant investment for homeowners in Charleston, SC, and beyond. According to the US Department of Energy, it’s estimated that in 2015, 55 percent of the total energy consumption in American homes was for heating and cooling purposes.

Your residential HVAC system allows you and your family to enjoy comfortable indoor thermal conditions regardless of the state of the weather outside. It relies on intricately connected components to facilitate this function.

However, these components require frequent maintenance and periodical repair or replacement services to maintain optimal performance all year round. With that in mind, no matter how DIY-savvy you may be, performing any of these services could have detrimental consequences if you’re not trained to handle the job.

That’s why you may need to contact a reliable HVAC company, and finding one can be a difficult task if you don’t know the distinguishing qualities of a reputable HVAC contractor.

Therefore, here are some of the top characteristics that describe a reliable company.

It’s Locally Owned and Operated

When in need of heating and AC services, you should always try to choose an HVAC company with a physical office that’s within the area. Similarly, avoid a contractor that only has a truck and business card with their phone number on it.

Instead, select an honest company, one that you can build a relationship with and rely on for your residential HVAC needs for years to come. By choosing a company with a physical location, you can be assured of accountability and it reduces the chances of you falling victim to a scam.

You should also select a locally owned and operated air conditioning company to ensure that you have a trained technician you can rely on in case of an HVAC emergency. A company located five or more towns away may not be in a position to help you under such circumstances.

It’s Fully Certified, Licensed, and Insured

As aforementioned, your home’s HVAC unit is an important investment, which is why you’d want only trained specialists to handle its maintenance needs. When selecting an HVAC company, you should strive to ensure that the contractor you hire has the appropriate certifications, licenses, and insurance coverage plans required to do the job.

HVAC services typically entail sophisticated procedures that can be hazardous especially when dealing with gas-powered equipment. That’s why your technician should have the necessary knowledge, training, and licensing. The company should also be registered with state authorities and keep their licenses and related paperwork up to date.

Besides ensuring that the company you choose has the special certifications relative to their area of operation, you should also make sure that they’re fully insured. Insurance protects you from any liability in the event of an accident during any residential heating and AC service. This means that you won’t have to pay a dime if an employee gets injured on the job or if they make a damaging mistake when handling your unit.

It Offers References and Referrals

The company you choose should have a good reputation within the local Charleston, SC, community. A contractor with a good reputation locally shows that you can trust the technicians to deliver quality craftsmanship and outstanding customer service. They should also be able to provide references and referrals upon request.

This information can help you determine if they can complete your project within the estimated time and budget. To learn more about their standing with the local communities, you can ask the contractor if they conduct final inspections after completing an HVAC service. You can also evaluate their online reviews to check their complaints and ratings.

It Coordinates Residential HVAC Inspections

When looking for an HVAC company, your potential contractors should be able to conduct a detailed HVAC inspection to determine the appropriate solutions based on your needs. The home evaluation service should factor in your home’s square footage, the position of the windows, and the R-value of insulation.

It may also involve inspecting the ductwork for leaks, loose components, and insulation problems. Additionally, your HVAC service provider should evaluate your unit to ensure that it’s properly sized based on your household’s heating and cooling needs.

After the home evaluation, a reliable HVAC company should provide a written and comprehensively itemized estimate.

Competitive Pricing

Money saved from cheap HVAC installation services could mean more expenditure on energy bills as well as repair and maintenance costs in the future. That said, when selecting an HVAC company, it’s probably in your best interests to avoid hiring a contractor that promises low-priced heating and AC solutions.

Companies that guarantee cheap services rarely prioritize spending their funds on maintaining their equipment and updating their licensing and insurance coverage. Therefore, your goal when seeking an HVAC contractor should be to choose a professional that offers cost-effective HVAC solutions.

Prompt Response to Service Requests

Ideally, a premier HVAC company should be able to provide emergency services upon request. After all, your residential HVAC system can break down unexpectedly.

Even when the HVAC issue you may be experiencing doesn’t qualify as an emergency, reliable heating and AC service provider should arrive on time following a request and complete their activities within the agreed time frame. This should remain constant regardless of whether you need an HVAC installation, repair, or maintenance service.

Your company selection should also be quick to answer your calls. In that regard, it’s probably best to avoid companies that you can’t conveniently reach over the phone. A reliable service provider should appreciate your value as a customer and strive to earn your trust.

It Can Provide Environmentally Friendly HVAC Solutions

A reliable HVAC company in Charleston, SC, should use eco-friendly practices to help maintain your residential heating and cooling unit. This can be confirmed through certification.

The US Department of Energy offers the distinguished Home Performance Green Certificate, which acknowledges the ability of an HVAC contractor to offer environmentally friendly heating and AC solutions.

5 Signs That You Need A Heating And AC Service | Charleston, SC

Heating and AC services are required to keep your heating and cooling system in working order. Sometimes it is difficult to determine whether or not you have to hire a contractor to repair your furnace or air conditioner. The sooner you realize that there is a problem, the sooner you can get it fixed. The sooner it gets fixed the less money you will be wasting on ineffective equipment that uses a lot more energy than it is supposed to. Carney & Son 72 Degrees Air Conditioning & Heating in Charleston, SC would like to inform you of five signs that your heating and air conditioning system is in need of a service.

1. It Is Not Working

This is one of the most obvious signs but if your heating or air conditioning system stops working then it is time for you to call your heating and AC service provider to come take a look at what is causing the malfunction. There are a variety of different reasons why your heating and AC system might not be functioning thus it is best to get a professional to take a look at it. They will be able to identify the cause of the malfunction and advise you on possible ways to repair it. They will also be able to repair or replace any problematic components. If your heating system or air conditioner stops working then it is best to call a service provider immediately because you do not want to be left without heating during the winter or without cooled air during the summer.

2. Strange Sounds

When something that is supposed to be silent makes a noise then that is a sign that there is something wrong with your furnace or air conditioner. It is normal for there to be a slight sound when you start up your heating and cooling system but if the sound gets louder or persists then you should hire a heating and AC service provider. If there is a squeaking or grinding sound then you should turn off the system immediately. Something could have broken off and gotten stuck in your system. If you keep the system on then you run the risk of damaging the other components. Carney & Son 72 Degrees Air Conditioning & Heating in Charleston, SC always recommend hiring a professional to come to inspect your heating or AC system. They will know what to look for and how to repair it which will save you a lot of time and effort.

3. Air Flow Problems

Your air conditioner or heating system should be producing treated air at a steady pace. When the airflow becomes irregular or there is no airflow at all then something is amiss. Sometimes certain rooms are hotter or colder than other rooms or it feels like your home is never hot or cold enough. If this is the case then something in your system is faulty and the air conditioner or heating system will work harder than normal to produce the same amount of treated air. This will cause more wear and tear on your system which will lead to more frequent repairs. If you are experiencing any airflow problems then it is best to hire a heating and AC service provider to come to take a look. Sometimes it’s as simple as replacing the filters in the ducts or other times it can be a more serious problem.

4. Foul Smells

There is nothing worse than having your house smell moldy or like burnt dust. You would like your house to smell fresh and clean. If your air conditioner or furnace starts producing a smell then you should call a heating and AC service provider as soon as possible. If there is a slight dusty smell when you first turn on your air conditioner after the winter or your furnace after the summer then it is normal. It is only abnormal when the smell persists for hours or days. The ducts that allow the treated air to flow into your home might be dirty. If you smell mold then there is a chance that moisture got trapped in your system which caused mold to grow. Mold spores can exasperate the symptoms of a person with lung disease. It can also be difficult to remove all traces of mold that is why it is best to hire a professional heating and AC service provider.

5. The System Is Cycling On and Off Frequently

When the air conditioner or heating system has produced enough treated air so that the house is at the ideal temperature, the system will shut off to conserve some energy and will only turn back on when it is required to produce more air for a comfortable temperature. If your air conditioner or heating system turns off and on too frequently then it could be an indication that the thermostat is not working properly. Some of the common things that can cause your system to turn off and on too frequently are low refrigerant levels, clogged filters or the evaporator coil is dirty. It is important to get a heating and AC service provider to do an inspection when your systems are not working as they should. This will prolong the system’s shelf life and spare you some money in the long run.

Now that you know the signs of when you should hire a heating and AC service provider, you can make informed decisions about your heating and cooling system. Carney & Son 72 Degrees Air Conditioning & Heating in Charleston, SC provides a wide range of services that will keep your air conditioning and heating system run at full speed.

Air Conditioner Repair Service: What You Need To Know About Your Air Conditioning System | Charleston, SC

How well do you know your air conditioning system? Do you know how old it is or when it was last serviced? Do you know what signs to look for and when to contact a professional air conditioner repair service provider for assistance? Not many people do. These are important things to be aware of. The better you know your air conditioning system and when to call for help, the better your air conditioning system will be. The best way to care for your air conditioning system Is to hire an HVAC technician for recurrent maintenance services, however, there will be times when an urgent repair is needed. In cases, of a serious air conditioning system malfunction, it is important to have a reputable and effective HVAC technician on hand. If you live in or around the Charleston, SC, area, contact the staff at Carney & Son 2 Defrees Air Conditioning and Heating for all of your air conditioner repair and service needs.

Knowing What to Look For

Preventive maintenance services are typically all you need to care for from your air conditioning system. Your preventive maintenance HVAC technician will periodically inspect, repair, and maintain your air conditioning appliance to ensure optimal operations and fewer breakdowns occur. You can assist with your air conditioning system’s preventive maintenance care by paying attention to your appliance and reporting any anomalies to your local air conditioner repair provider.

In order to know what to look for, you need to know what you are seeing. The air conditioning system is complex. There are many important parts to the air conditioning systems, however, there are some that matter more than others. The most important components of the air conditioning system are the coils, vents, air ducts, compressor, refrigerant, and fans. These components are responsible for the functioning of your air conditioning system. If any of these components become faulty or fail for any reason, contact an emergency air conditioner repair service provider for urgent assistance. The faster you fix a malfunction, the less damage will occur, and the faster you can get back to properly air-conditioned air.

Vents and Air Ducts

The vents and air ducts are needed to take in and push out air. The take-in vents help remove heat and humidity by pulling in the hot air. The Return vents are needed to return cool air back into your home’s atmosphere. Each vent is typically attached to a channel or air duct. This air duct is responsible for channeling air to and from the air conditioner system in a safe and controlled environment. These components are easy to maintain with the help of an air conditioner repair service provider. Preventive maintenance for air conditioning vents and air ducts typically involves cleaning and replacement of the air filters.

If a hole or opening were to form in your air ducts, your air conditioning system will start to work less efficiently. If you notice weathering around your air conditioning system air ducts or opening, contact your local air conditioner repair service provider. If you live in or around the Charleston, SC, area, contact the staff at Carney & Son 72 Degrees Air Conditioning and Heating for professional air conditioner repair service in the cases of a fault with your air ducts or vents.

Refrigerant & Coils

The refrigerant may be the single most important feature of the air conditioning system. Although other components are needed in order to make the refrigerant work the way it was intended, air conditioning wouldn’t be possible without this special chemical. Refrigerant is a compound that can typically be found in liquid or gas form. The state in which refrigerant is found is completely dependent on the surrounding temperature. Refrigerant has an extremely low boiling point, of around 40° to 50° degrees. This compound can absorb the heat in the air. The intake vents in your air conditioning system, take in the warm air from your home’s atmosphere. As the air passes by the refrigerant, the heat and humidity are absorbed. If your air conditioning system is removing heat and humidity from the air, it could have something to do with these components, contact your local HVAC technician for urgent air conditioner repair service and inspection.

Refrigerant is always in liquid or gas form. The coils are used to contain refrigerant in their gaseous and liquid state. The evaporator coils are used to allow the refrigerant to absorb the heat. The compressor coils compress the vapor refrigerant back into liquid form by compressing it. Once the refrigerant is cooled and compressed it is then sent back through this process in order to remove all heat and humidity from your home’s atmosphere. Things such as refrigerant leaks and compressor failure can cause issues with your air conditioning system’s ability to cool air. If your air conditioning system seems to be leaking a coolant-like liquid or is straining to operate, contact your local heating and air conditioning repair company for urgent air conditioner repair service.


The fans are also an extremely important component of the air conditioning system’s ability to generate cool air. The fans help push air and cultivate cool air to be returned to you via the return vents. If you are having issues with your fans, you may notice the absence of a breeze coming from your air conditioning system. If your fans stop working, it could be due to a connectivity issue, or other problem. Without a fan, your air conditioning system will not be able to force air out or effectively generate cool air. If you recognize the signs of fan failure in your air conditioning system, contact your local air conditioner repair service provider.


The compressor is a mechanical device within the air conditioning system, that moves the refrigerant from the evaporator coils to the compressor coils. This is another important component that could affect the functionality of an air conditioning system if it wasn’t working properly. You may be able to recognize signs of compressor failure by the sound of your air conditioning system, or lack of cool air. If the air coming out of your air conditioning system is still humid or hear a strained mechanical noise coming from your air conditioning system, it could be due to an air conditioning system failure. Contact a local and reputable HVAC repair company for air conditioner repair service and maintenance.

If your air conditioning system is experience malfunction or failure, it could be due to one of the previously mentioned components failing or malfunctioning. In the case of an air conditioning system issue contact a licensed professional to help. If you live in or around the Charleston, SC, area, contact the staff at Carney & Son 72 Degrees Air Conditioning & Heating for professional air conditioner repair service and maintenance.

Where To Go For An AC Repair | Charleston, SC

Do you know that Charleston, SC has a humid subtropical climate? Of course, you did, this means wet, mild winters and hot, humid summers. Summer temperatures are usually in the 90s and can even reach over 100 degrees. When temperatures reach this high, homeowners will make more use of their air conditioners.

When an air conditioner breaks down for any reason life will soon get unbearably hot and sticky causing even more trouble for people with illnesses like asthma, COPD, and allergies, and for those looking after young children or elderly relatives, it is going to get stressful trying to quickly find a reputable AC repair company.

It will also have highly trained technicians who are licensed, bonded, and insured, and offer a labor warranty and 100 percent customer satisfaction guaranteed, luckily you’ve found such an AC repair company that is the team at Carney & Son 72 Degrees Air Conditioning and Heating.

The Most Frequent AC Repair Problems in Charleston, SC.

The period running from late spring to the end of summer is when we use our air conditioners the most. It is also the time when they are most likely to break down. Carney & Son 72 Degrees Air Conditioning and Heating will always advise our customers to have their air conditioners regularly serviced during the shoulder seasons to avoid delays or endure any waiting time.

This routine service is the best thing you can do for your unit. It will make sure that everything is working safely. Your air conditioner will also run more efficiently and save you money on energy bills. We also suggest that you schedule your service appointment long before the summer heatwave begins.

This will give you greater peace of mind from the risk of a breakdown and catch any issues before the hot weather begins. Subscribing to regular check-ups, understanding when to schedule an AC repair, and keeping an eye out for any possible problems will help you avoid expensive repairs and long wait times.

  • Icy Evaporator Coils: Warm air from within your home is extracted by a fan and is then blown over the evaporator coils. Coolant within the coils absorbs the heat from the warm air and the cooler air is blown back into your home. Restricting the airflow over the coils will cause the evaporator coils to freeze over. There are several reasons why the airflow could be restricted.


  • Dirty Air Filters: if the air filters are not cleaned or replaced regularly, they will limit the amount of warm air being blown over the coils. Dirty air filters will allow more dirt and other pollutants to enter your home.


  • Coolant leaks: An air conditioner will need an ideal level of coolant in it. A leak will cause this level to drop. Less coolant in the air conditioner will mean less cooling effect from the unit as less heat from the warm air will be absorbed. This will increase the risk of freezing the coil.


  • The Evaporator Coil is Dirty: Dirt has an insulating effect and if the coil is not cleaned it will reduce the amount of heat absorbed by the coolant.


  • Defective fan: An underpowered fan will not blow as much warm air over the coil.

Some of these tasks, like replacing or cleaning the air filters you can do yourself. But a routine service from a technician from Carney & Son 72 Degrees Air Conditioning and Heating cover all the tasks included in your chosen package. Ignoring a problem with your AC whether it be the fan or the evaporator coil will eventually freeze the components of the AC and at the very least you will need to turn the air conditioner off to allow it to thaw. Nor something you want to do on a hot summer’s day!

Low Levels of Coolant & Signs of a Coolant Leak Includes

  • It is important to have the right level of coolant in the air conditioner for it to work efficiently.


  • If you hear hissing sounds, you probably have a coolant leak and need an AC repair.


  • Big energy bills are a result of not having enough coolant in the air conditioner. This means that less heat is absorbed by the evaporator coil. This has a knock-on effect on the rest of the components in your air conditioner. They will need to work harder to keep the correct temperature, and as they work harder, they will use more and more energy, thus increasing your electricity bill.


  • Any component that works harder is going to get hotter, so it is more likely to overheat, burn out, and be replaced.


  • Less coolant will mean less cool air. Without enough coolant, the evaporator coil does not remove as much heat, so the expelled air is warmer.


  • Humidity levels are higher because warmer air will carry more moisture than cooler air., so the air blown back into your home will be humid.

AC Drain Line Troubles

As we have said earlier warmer air contains more moisture than cold air, so the hotter it is the more humid it is. The excess moisture removed from the warm air gathers in the drip pan and then flows outside through the AC drain line.

If the drip pan or drain line becomes blocked for any reason you could experience the following issues

  • Increased humidity in your home – a blocked AC drain, or drip pan will increase the humidity levels in your home.


  • Puddles of water around the air conditioner – a blocked drip pan or drain line will not allow the water to escape your home. The drip pan will fill up and overflow, into your air conditioner and onto your floor.


  • Mold or mildew is growing in the drain line – any smell of mold inside your home could be due to mold growing in the drain line or drip pan. These need to be cleaned regularly.


  • Any blockage could cause the air conditioner to shut down, so it is worth checking to see if the drain is blocked, by dirt or leaves.

Keeping Charleston, SC Cool and Safe.

Having your air conditioner break down during a hot spell will be a very stressful experience. That is why we have highly trained technicians available 24/7. If you need an AC Repair, then please call Carney & Son straight away.
