6 Signs That It Is Time To Schedule AC Repair | Charleston, SC

If you have spent at least one summer in Charleston, SC, you know how hot it can get. The average temperature during the summer is between 85 and 88 degrees. It is often humid, which can make it feel hotter than it actually is. When the temperature outdoors heats up, most people stay indoors with the air conditioner on. If your air conditioner isn’t functioning properly, it can be impossible to get comfortable in your home. The best way to prevent a complete air conditioning breakdown during the hottest time of the year is to be able to recognize the signs that it is time to call for AC repair. If you can catch the problem early, you can prevent a minor issue from becoming a major one.

If your air conditioning system has any of the following issues, you should call for AC repair right away.

#1 No Cold Air

The most obvious sign that it is time to schedule an appointment for AC repair is if there is warm air coming from the vents in your Charleston, SC home. Before you call for a repair, you should check your thermostat. First, make sure that it is set to the cooling mode. If it isn’t, the system won’t produce cold air. Next, check the temperature setting. If the temperature in the home is lower than the set temperature, the air conditioner won’t kick on. When you adjust the thermostat, your system should start pumping cold air.

If everything on the thermostat checks out, you should schedule an appointment for a repair. There are a few issues that could be causing the problem.

  • Failed compressor: If the compressor has failed, your system won’t be able to generate cold air.


  • Low refrigerant: If there isn’t enough refrigerant in your system, it won’t be able to generate enough cool air for your home to reach the desired temperature.


  • Faulty thermostat: If your thermostat isn’t functioning properly, your system won’t register commands, making it impossible for the air conditioner to function properly.


  • Air duct crack: If there is a crack in the air duct, the hot air from outside will be pulled into the air ducts and circulate throughout the home.

#2 Poor Airflow

If the airflow coming from the vents in your home is poor, you should call a professional in AC repair. Over the course of a year, 15 pounds of dirt, dust, pet dander, and other debris can build up in the air ducts. If you haven’t had your ducts cleaned in several years, the debris could be blocking the air ducts, causing poor airflow. If there is a crack or break in the air ducts, the cold air can escape through the hole, causing poor airflow. You could also have an issue with your system’s fan or blower. It would take the knowledge and experience of a professional in AC repair to find the cause of the problem to make the necessary repair.

#3 Thermostat Issues

The thermostat in your home is your HVAC system’s brain. If it isn’t working properly, your air conditioner won’t know when to turn on. It also won’t know how cool you want your home to be. If your thermostat is experiencing any of the following signs, you should schedule an appointment for a repair.

  • Your thermostat has no power.
  • Your thermostat is unresponsive.
  • The room temperature and the thermostat settings don’t match.

If your thermostat needs to be replaced, you should talk to your HVAC tech about the options available. Modern thermostats have features that your old one may not have had. You can install a programmable thermostat, which can save money on your cooling costs. You can set your thermostat to turn the system down when nobody is home and then up before your family returns home.

You can also have a Wi-Fi thermostat installed. You can control your thermostat from your Smartphone or tablet from anywhere in the world as long as you have an internet connection.

If you have a Google Nest or Alexa, you can buy a thermostat that works with these devices and can be controlled by the sound of your voice.

#4 A Foul Smell When Your Air Conditioner Is Running

When you turn on your air conditioner for the first time during the cooling season, it is not uncommon to smell dust. After a few minutes, the dust will burn off, and the smell will dissipate.

If you smell mold while the system is running, you should schedule an appointment for a repair. There could be mold growth in the air ducts or in the system itself. When this happens, mold spores can circulate throughout the home, which can cause your family to develop allergy symptoms. If a member of your family has a respiratory issue such as chronic bronchitis, asthma, or COPD, the mold spores can make their condition and the symptoms worse. You will need a professional in AC repair to clear the mold, which will improve the air quality in the home.

If you smell something burning in your home, there could be a burned-out wire, which can result in an electrical fire. It is best to turn off the air conditioner and call a professional in AC repair.

#5 Moisture Or Pooling Liquid Around the Air Conditioner

If there is moisture around the air conditioner, you should schedule an appointment for a repair immediately. The issue could be something simple like a clogged or disconnected condensate hose. It could also be a refrigerant leak, which is much more serious.

#6 Strange Sounds Coming From the AC

A properly functioning air conditioner should be relatively quiet when it is running. You will also hear an occasional clicking sound when the system kicks on and off. If you hear any strange sounds such as a banging, clanging, or whining sound, you should schedule an appointment for a repair.

Understanding how your HVAC system is supposed to tow or will help you determine when to contact a heating and AC service provider for urgent repair and maintenance. If you live in or around the Charleston, SC, area, contact Carny and Son 72 Degrees Air Conditioning and Heating for all of your HVAC maintenance and repair needs.

How Does Your Air Conditioning and Heating System Function

Heating and air conditioning are two separate things and operate in different ways. Most HVAC systems share some components and have completely different systems for different functions. The air conditioning unit and heating unit are separate appliances that share air ducts and vents to provide hot and cool air at the push of a button. The way your HVAC system operates depends on what type of HVAC system you own, however, they all work fundamentally the same.

Heating systems operate with either a furnace or boiler. Air conditioning systems have 2 air conditioning units that work in tandem to generate cool air. Each system requires regular maintenance and upkeep in order to remain working efficiently and properly. A properly maintained HVAC system will save your money on your energy bill, have fewer breakdowns, and ensure your comfort. If you are in need of a heating and air conditioning service provider, in the Charleston, SC, area, contact Carney and Son 72 Degrees Air Conditioning and Heating for all of your HVAC repair and maintenance needs.

Air Conditioning

Air conditioning is a complex process. Cooling air takes a multitude of steps in order to accomplish. There are 5 main components of an air conditioning system that makes it work the way it does. Those main components include:

-The fans

-The compressor

-The Refrigerant

-The Evaporator Coils

-The Air Ducts & Vents

Without these 5 main components, your air conditioning system would not work. If any of these components were to become faulty or compromised in any, contact a heating and air conditioning service provider right away.

All of these components are necessary for all air conditioning appliances, regardless of the type and make. Portable, window units, mini-split, and central air conditioning and heating systems all require these same 5 things. The components may be set up in a different way, however, they will all have them.

Air Ducts and Vents

The air ducts and vents are obviously important, however, they are often forgotten and neglected. The air ducts and air vents are responsible for releasing the air into your environment once it’s been cooled and conditioned. Your air ducts and vents may be large or small, depending on what type of air conditioning system you have.

Window units and portable air conditioning systems only have one set of vents and air ducts in most cases. However, a large air conditioning and heating system, such as a central HVAC system will have multiple vents and air ducts all over the property. These components must be properly maintained and cleaned in order to efficiently and safely cultivate a cool or heated environment. Contact a professional air conditioning service provider for regular air duct maintenance and vent cleaning services.


Fans are used to push the cooled and conditioned air through the vents and air ducts and into your environment. If your fans aren’t working properly you will need to have an air conditioning service provider assess the issue urgently. Without fans, you’re heating and air conditioning will not work properly. Contact an air conditioning service provider to fix the issue before it affects other components of your HVAC system

The fans are also used to cool the air inside of the air conditioning unit. Fans are not the only cooling component of the air conditioning system.

Refrigerant and Evaporator Coils

The refrigerant in your air conditioning system may be the most important component there is. The refrigerant is a chemical that comes in liquid form. Refrigerants are sometimes referred to as coolants. Refrigerants are able to absorb heat and moisture from the air. It is highly sensitive to temperature. When it absorbs heat, the refrigerant is turned into a gas and is transferred to and from the inside air conditioning unit, to the outside air conditioning unit. Without refrigerant, the cooled air would remain hot and humid. If your air conditioning system is working but is blowing out cool air, it could be due to a refrigerant leak. If you notice signs your air conditioning system is low on refrigerant, contact a professional air conditioning service provider right away.

The evaporator coils are there to hold the refrigerant. Since the refrigerant is either always in gas or liquid form, it needs to be held in place by metal coils. These metal coils are known as evaporator coils. These evaporator coils hold the refrigerant as air and fans blow over the chemical solution.


The compressor is essential to operating the air conditioning system. The compressor is in charge of moving the refrigerant to and from the inside and outside air conditioning units. Without the compressor, the refrigerant would remain stagnant and cool air would not be generated easily.

A broken compressor makes rattling and ticking sounds. If you notice these sounds emanating from your air conditioning system, contact a professional heating and air conditioning service provider right away.

If you are in need of a heating and air condition service provider for your HVAC system, contact Carney & Son 72 Degrees Air Conditioning and Heating company.

4 Ways Regular Heating And AC Service Protects Your Home | Charleston, SC

Your HVAC system is one of the largest investments you will make inside of your home. Therefore, you want to make sure that you properly protect it which means scheduling a regular heating and AC service in Charleston, SC. One regular inspection every year can help you prevent an unexpected breakdown and avoid the associated costs with emergency heating and AC service. In addition, regular repair will help you keep your energy bills down by making your system more effective. In return, you will be contributing positively to the enrolment.

These are just a few of the many benefits that come with regular heating and AC service. There are many more. While most people hate calling an HVAC company unless they have to, calling one for your annual maintenance is the smartest decision you could make. Keep reading to find out the many more benefits of heating and AC service and make a conscious note to call your local HVAC technician and get on the schedule if you haven’t already.

Save Some Cash

First of all, one of the biggest reasons to consider heating and AC service on a regular basis is the simple fact that it will save you money. Regular maintenance helps you avoid breakdowns by fixing problems before they become major. Most of the time an HVAC system does not just break down. There are usually rusty parts, damaged items, or clogs that occur first. A regular maintenance visit helps you catch all of these things before they break down and get repairs on a timely basis.

Plus, when your HVAC system is working properly it saves you money. A properly operating system will lower your energy bills each month easily paying off your maintenance visits. The same way you wouldn’t skip an oil change, you shouldn’t skip a regular service on your HVAC system. A more efficient system simply costs less to run helping reduce your Charleston, SC energy bills.

Even more enticing is the fact that HVAC maintenance helps keep your warranty valid. Even if you have a new HVAC system you will benefit from regular service calls because they are required to keep your warranty valid. Given the high price tag attached to your HVAC system, you want to ensure your warranty stays valid so if something happens you are covered. Paying for annual service is a lot cheaper than paying for a new HVAC system if something malfunctions.

Extend the Lifespan of Your HVAC System

On that note, keep in mind that a properly functioning HVAC system will last for many more years than one that is not maintained. Therefore, proper heating and AC service is essential to extending the lifespan of your HVAC system. Would you rather pay for a new system every ten years or every 15 years? With regular maintenance, some systems can even make it up to 20 years which can save you a lot of money and really make the extra maintenance costs well worth your investment.

Better Air Quality Within Your Home

Believe it or not, if you do not properly maintain your HVAC system the air inside of your home can quickly become more polluted than the air outside of your home. This is because people who have their heat or AC on tend to keep their windows and doors sealed shut. As a result, fresh air never opens the home, so the overall air quality is dependent on how well the HVAC system is able to clean it. As a result, pollutants can get recycled over and over which can ruin the air quality in your home and make breathing worse on family members who suffer from things like indoor allergens or asthma.

There are a lot of air pollutants that live in your home even if you keep a clean and organized home. They include pollen, dust mites, pet dander, and pollen. It also doesn’t take too much for mold to grow hidden away in your ductwork or basement allowing mold spores to enter the air you breathe every day. As part of a heating and AC repair service, the technician will thoroughly clean your HVAC system helping to remove and prevent dirt from accumulating inside your machine.

If you are concerned that your AC or heating vents are blowing musty air, use this opportunity to discuss the issue with your heating and AC repair tech. There is a good chance that mold may be growing in your ducts and they can help set up a professional air duct cleaning service to have all of this removed. However, with regular heating and AC service, you can prevent this from happening by ensuring that only clean and well-filtered air travels through your vents on a regular basis.

Protect Your Home

While you don’t often think of your HVAC system as a way to protect your home, regular heating and cooling do a lot to keep your home safe. If you happen to be away on vacation and your HVAC system breaks you could come home to find frozen pipes that result in water breaks as the weather warms again leading to expensive water damage.

On the other hand, if your HVAC system is not properly removing humidity from the air it can lead to moisture collecting all over your home leading to mold growth and the destruction of your personal property. These are just several of the many ways that you depend on your HVAC system to protect your home. Keeping it working at full power via heating and AC service is just the smart choice.

If you are ready to book your maintenance call give Carney & Son 72 Degrees Air Conditioning and Heating a call today. We will be happy to book a heating and AC service call with you to check-in and make sure that everything is functioning correctly before we head into another hot and humid summer.

It’s not difficult to find an HVAC company to fix today’s problem with your AC or heat. The question is, which HVAC company is the one that you can work with for the long term?

Because we’re more than just a repair and maintenance HVAC company, we know heating and cooling systems are part of your home and lifestyle. We help you keep your system up to date, and maintain your comfort equipment so that it serves you well. We’re a dedicated team — even our retired founder still puts his hand in from time to time to help us make a difference.

Keeping Your Tradition of Wise Choices for Your Home

Do you have an older system, perhaps one that you’ve relied on for some time, a quality air conditioning and heating system that hasn’t needed many repairs? When it comes time to make changes, we know you want to ensure that it makes sense, that you’re replacing quality with quality, and that the numbers are right for you both in equipment cost and efficiency. After all, that’s one big reason for upgrading your equipment, modern equipment is so much more energy-efficient than it’s worth considering even if your existing system is doing all right.

Keeping Your Home in the Zone

One of the big energy savings moves we suggest to many of our HVAC company’s customers is a “zoned” system. That’s a simple but revolutionary change where your system’s heating and cooling are distributed selectively, managed by separate thermostats, through separate ducts. You might choose to make your bedrooms, your living room, and your basement the heart of three zones. When you manage your comfort in each zone as needed, you can target your HVAC system’s efforts to the areas where you want the perfect temperature. You don’t spend money heating or cooling spaces when you’re not using them.

Air Quality Can Enhance Your Comfort

Have you considered actively filtering and managing the humidity of your air? As your HVAC company, we have some great solutions for air quality. In addition to temperature control, this can help improve your days considerably. It’s especially true if you have people in your home who are sensitive to the air they breathe and would do better with the kind of air they experience in commercially managed buildings. We can add features to your existing HVAC system to humidify the dry air of wintertime, and remove humidity in summer. We can also add HEPA filters and other air purification features to remove pollen, pet dander, dust, and other irritants from the air. Add a vent cleaning to keep dust and dirt from accumulating and staying in circulation, and you’ll definitely breathe easier.

Intelligent Thermostats and Other Active Temperature Management

The smarter your HVAC controls, the more you can save on your energy budget. Intelligent controls also tend to work your heating and cooling less hard, planning for target temperatures rather than just reacting to the current temperature. They also help you reach that magic 72 degrees only when you’re around to enjoy it, following a set schedule you program or learning what you prefer and adapting over time. If you have a zoned system, each thermostat is managing its space for even more savings and comfort. If you decide to adopt smart home technology, thermostats contribute along with external factors like the weather to balance your temperature and comfort even more accurately.

More than Cost and System Age: The Factors Involved in Deciding to Upgrade

As a full-service HVAC company, we’ve been around a while. We’ve seen systems last a long time. One thing to think about, though, is the changes in technology that have produced significantly improved energy efficiency. We can help you run the numbers and balance your energy costs, repair costs, seasonal equipment, and installation promotions, and other factors to know when it’s the right time for you to make the move to new HVAC equipment.

Maintenance Is About Confidence in Your System

If you trust your system, you want to treat it well and help it last. We perform careful maintenance and make sure your system is ready for each season.

We’re Ready to Count You as One of Our Valued Customers

How Our AC Repair Team Keeps Your Temperature Just Right and Your Comfort Perfect | Charleston, SC

Balance and Reliability in Your HVAC System Keep Your Air Quality Consistently High

Keeping your cooling system focused on the perfect temperature, humidity, and air quality take a lot of work behind the scenes. At Carney & Son 72 Degrees Air Conditioning & Heating, we’ve been doing intelligent AC repair and maintenance for our Charleston, SC clients for over 30 years. From your cooling unit to your air distribution, every component of your HVAC system carries its share of the load. If the fans aren’t up to the job or the ducts are obstructed, the compressor works harder for the same end result. When we perform AC repair and maintenance work, we think of the whole picture and make sure that your system is running smoothly, including changing filters and cleaning ducts.

System Capacity Keeps It Resilient and Responsive

An important part of your AC system is the performance of your cooling unit. Not just its ability to cool, but its ability to supply enough cooling to bring your home to the target temperature in a timely fashion, and keep it there consistently. Just like with a car engine, if your cooling system can’t keep up, it can get overworked and require more frequent AC repair. As your system gets older, especially if it hasn’t received the maintenance and cleaning that keeps it efficient, it can have lower performance than when it was new. In fact, a key part of designing an efficient cooling system is making sure the capacity is right for your home.

Air Distribution Manages Your Whole-House Comfort

One of the challenges we enjoy meeting is ensuring that your home’s comfort level is consistent throughout. When the cooled air is distributed effectively and managed properly by your temperature control system, you’ll have few if any warm spots or cool spots, just consistent comfort. In many older homes, there is only one temperature control, so only one place in your home is sure to be the right temperature. If your thermostat is in a living room that has little sun, your sunny bedrooms will be warm. Your basement may be overwhelmed with cool air and be quite chilly. If you’ve found yourself closing or blocking vents to manage your home’s temperature, you know exactly what we’re talking about.

In the Zone Means Evenly Cooled

These days, there are ways to better manage your overall comfort level. One of the most effective is a zoned system that divides the ducting to distribute cool air in several zones. Separate fans and thermostats complete each zone, allowing the temperature in each part of your home to be managed separately. You can also use thermostat technology to intelligently manage each zone, leaving the basement untouched unless you’re down there, for example, and letting the bedrooms warm up during the day when they’re not in use. When you manage the temperatures, you also manage the demand on your cooling unit and reduce the need for AC repairs since it works less hard when it doesn’t have to cool the whole home all the time. When you divide into zones, you also avoid the blasts of cool air that single-zone systems tend to produce as they direct cool air to the entire house.

Temperature and Humidity Management Work Together

Along with temperature, humidity plays an important role in your comfort. Our AC repair team often upgrades systems with dehumidifiers for the summer that take some moisture out of the air to help the cool air feel even more comfortable. We can install thermostats that also sense and control humidity, providing an extra degree of comfort that you’ll appreciate, especially if you come in from an especially hot and humid Charleston, SC day outside. The thermostats we recommend also manage temperature using various factors from simple time-based settings according to your daily habits, to more adaptable devices. Some even remember how you prefer your comfort and adjust, often anticipating the comfort level you’ll need and getting the system to work cooling to your preferred temperature before you arrive.

Smart Home Technology Is a Big Part of HVAC Systems These Days

Whether you have a basic smart thermostat or one integrated into your smart home controls, adding convenience often adds efficiency. Even voice control, through wall-mounted panels and kitchen devices or your smartphone app, can help you set your climate controls just the way you like them. Our AC repair team can help integrate with your smart home provider. Once you’re updated, if you have seniors at home who need a cool environment, smart systems can send you an alarm if something’s wrong and your home is warming up. You can then call our AC repair team to meet you and see what’s wrong. Smart home providers can integrate your HVAC system controls with external factors such as weather reports and forecasts, automatic shades and curtains, and occupancy sensors to “tune” your system for well-balanced performance.

Air Quality Features Add an Important Touch

In addition to humidity, many people are sensitive to air quality. We can perform periodic duct cleaning to ensure you’re not recirculating dust, and install HEPA filters and other air quality upgrades to ensure that your air is high-quality.

Maintenance Keeps Your System Reliable and Ready to Handle High-Demand Days

Much of our seasonal maintenance schedule is ensuring that your system is running smoothly and not working against dirty condenser coils, poorly lubricated fan motors, or dirty air filters. When we maintain your HVAC system, it also gives us a chance to catch the need for AC repairs before the system breaks down.

Let Our Team Fine-Tune Your HVAC System and Handle Your AC Repairs

We love to keep your home environment comfortable. Call Carney & Son 72 Degrees Air Conditioning & Heating for intelligent, experienced, and well-balanced heating and cooling that will keep you comfortable at the right price, year-round. We look forward to meeting you.

Once you’ve determined that it has nothing to do with the electricity, it’s time to call a professional for AC repair.


  • The AC runs but doesn’t cool the room. There’s nothing wrong with the machine turning on. It doesn’t, however, keep the room cool. When you put your hand in front of the unit, you feel nothing but warm air coming out of its vents. You know that it could be an issue with the filter or the freon but aren’t sure which is the problem. An AC repair tech is needed to get to the root of the air conditioning issue.


  • The room doesn’t cool evenly. Even though the air conditioner works, it doesn’t cool the air all the way. It could be due to a blocked vent or dirty filter. Again, it’s time to call a company specializing in AC repair so you can get the issue taken care of right away. It’s one less thing to worry about when having the unit looked at by a professional. They’ll have the machine up and running once again in no time.


  • Water drips from the AC. You can see a puddle of H2O on the floor. Many problems could be causing the issue. It’s best to work with an HVAC company to see why there is a problem in the first place. Unplugging the unit, so no one gets electrocuted is something we highly recommend. Then, call the AC repair tech right away to get the issue addressed before the air conditioner quits suddenly.


  • The AC makes strange noises. You can hear a problem going on with the air conditioner. It makes odd noises that you’ve never heard before. You can request assistance with AC repair right away because it can be indicative of a bigger problem taking place within the unit. Having the machine repaired and serviced regularly keeps you from needing to buy a new unit prematurely. It costs you money upfront but will save you a mint long in the future.

AC repair is something that you cannot put off for long. It’s something that you need to take care of right away. Without it, your home can become very uncomfortable quickly. Once you’ve hired a service technician to do a repair for you, you’ll have the name and phone number of a company to work with long into the future. That means that there will be no more panicking when your AC unit quits working in the middle of the night.

5 Signs That It Is Time To Call A Professional In AC Repair | Charleston, SC

Anyone who has spent a summer in Charleston, SC, knows how hot it can get. The temperature during the summer can reach 88 degrees and higher. Also, the humidity during the summer can make it feel a lot hotter than it actually is. Because the summers are so hot, you rely greatly on your home’s air conditioning system. The last thing you want is to experience a complete breakdown during the hottest time of the year. The best way to keep this from happening is to be able to recognize the signs that you need AC repair. If you recognize the signs early, a minor issue can be repaired before it becomes a major one.

#1 Warm Air Coming From the Vents

The most obvious sign that there is an issue with your air conditioner is if warm air is coming from the vents. Before you call for a repair, you should first check the thermostat. Make sure that the thermostat is set to the cooling mode. Also, you want to make sure that the temperature in the house is warmer than the setting on the thermostat. If it isn’t, the system won’t kick on until you adjust the thermostat.

If everything checks out with the thermostat, it is time to call a professional in AC repair. There could be a problem with the compressor, or the system could be running low on the refrigerant. You will need the knowledge and experience of an HVAC tech to determine the source of the problem so that it can be repaired. The sooner you schedule an appointment for a repair, the sooner your home will be cool again.

#2 Poor Airflow Coming From the Vents

If the airflow coming from the vents in your home is poor, it will be challenging for your home to reach the desired temperature. A few issues could be causing poor airflow, and you should have your system checked out by a professional in repair.

The problem could be a broken fan. If the fan isn’t working properly, adequate air won’t make it through the air ducts. The problem could also be with the air ducts themselves. When dirt, dust, and other debris build up inside the air ducts, it can obstruct the air coming from the vents. There could also be a crack or leak in the air ducts. When this happens, a large portion of the cold air will escape from the leak, resulting in poor airflow.

If you don’t have the problem repaired, your system will need to work harder to reach the desired temperature. This will result in higher energy costs, and it can shorten your air conditioning system’s lifespan.

#3 Strange Odors When the System Is Running

When you turn on your air conditioner for the first time during the cooling season, it isn’t uncommon for there to be a dusty smell. When the system isn’t in use, dust can settle inside, which will cause the smell. After a few minutes, the dust will burn off, and the smell will dissipate.

If you smell anything other than dust at the beginning of the cooling season, you should call for air conditioner repair. If you smell mold, chances are that there is mold built up in the air ducts or inside the system itself. This is a very serious issue because it can affect the air quality in your home. It is very unhealthy to breathe in mold spores, as your family can develop allergy symptoms such as sneezing, runny nose, itchy, watering eyes, and a sore throat. If a family member has respiratory issues such as asthma and COPD, mold can exacerbate the symptoms. The best way to keep your family safe and healthy is to call a professional in AC repair immediately.

If you smell something burning when your air conditioner is running, you should turn the system off and call a professional in AC repair immediately. The smell could be due to an electrical issue or burning insulation, which can cause an electrical fire in your Charleston, SC home. This is a major cause for concern and should be checked out by a professional in AC repair immediately.

#4 Strange Sounds Coming From the Air Conditioner

If the air conditioner in your home is functioning properly, you shouldn’t hear more than a low-level hum when you are close to the unit. You might also hear a quiet clicking sound when the system kicks on and off. If you hear any other sounds, you should call a professional in AC repair immediately. There could be a broken or disconnected part inside the system. Allowing the broken piece to rattle around inside the system will cause damage to more internal parts. There could also be an issue with the system’s housing. It would take the knowledge and experience of an AC repair professional to determine the source of the problem and make the necessary repairs.

#5 Moisture Around the Air Conditioner

There should never be moisture or water pooling around your system. If there is, you should call a professional in air conditioning repair immediately.

The problem could be something simple like a clogged, loose or cracked condensate drain hose. It could be something more serious like a refrigerant leak. If this is the case, it can be dangerous. Refrigerants are toxic and can be harmful to pets and small children. Also, as the refrigerant leaks, it will be difficult for your air conditioner to keep your home cool.

It is best to call a professional in AC repair as soon as you notice the moisture.

Maintaining Your HVAC System All Year Long With Air Conditioning And Heating Service | Charleston, SC

You might not think about HVAC maintenance very often, but it’s something every Charleston, SC, homeowner should have in mind. Not only is it important to have your AC running for the summer months, but you also need reliable heating when it gets cold in the winter. The best way to keep your HVAC system in working condition is to have an air conditioning and heating service professional perform maintenance regularly. To find out more about how you can keep your heating and cooling up and running and save yourself money, keep reading.

Seasonal Maintenance

The first step to taking better care of your AC and furnace is to get professional help. Even if you’re taking a peek at your HVAC system every now and then and keeping things clean, there are other things that need to be done to prevent problems. An air conditioning and heating service professional can perform seasonal maintenance to make sure your heating and cooling are ready for the demanding seasons.

It’s important to have seasonal maintenance done at the right time so you’re preparing your HVAC system for the demanding season and doing maintenance when you don’t need to use it. For most people, seasonal maintenance is easiest during the spring and fall. There’s a good chance you won’t need to use your heating or cooling during these seasons, plus you can get them ready for summer and winter when they really need to work.

Keep in mind that seasonal maintenance is only one part of the puzzle. If you want to keep your HVAC system in good shape, you need to call an air conditioning and heating service company when you have any problems.

Replacing Your Air Filter

One mistake a lot of Charleston, SC, homeowners make when it comes to HVAC maintenance is not replacing the air filter. Air filters are great because they remove contaminants from the air, but they can also become clogged and cause a serious reduction in airflow. The good news is, you don’t have to call a service professional to change your air filter every time.

Air filters need to be changed fairly often, and it depends on your household. If you live alone, you can get away with having an air conditioning and heating service expert change your air filter every six months during seasonal maintenance. If you have pets or live with other people, your air filter needs to be changed every three months or so. For large families with several pets, experts recommend an air filter change once every month or so.

If you have people in your home with allergies, consider talking to an air conditioning and heating service professional about upgrading to a better air filter. Investing in a HEPA air filter or one with a higher MERV rating can help keep the air in your home cleaner.

Proper Heating and Cooling Operation

You might not think about how you’re using your heating and cooling very often, but proper operation is important. The more you use your furnace or AC, the quicker it’s going to wear down and the sooner you’ll need to replace it. By the same token, you don’t want to avoid using your furnace or AC to the point where you aren’t keeping your home at a comfortable temperature.

One of the best things you can do to extend the life of your furnace and AC is to invest in a better thermostat. An air conditioning and heating service company can install a thermostat in next to no time, and you can get a great new thermostat without spending a fortune. Make sure you’re programming your thermostat so you’re only heating or cooling your home when you need to.

It’s also important to set your thermostat to the right temperature. As much as you may want to keep your home at a 60 degrees in the summer or 75 in the winter, you should try to stay between 64 and 68 degrees as often as you can. This will help reduce the demand on your HVAC system so it lasts longer.

When It’s Time to Replace

No matter how well you stay on top of maintenance, there comes a time when you have to replace your furnace and AC. As a homeowner, you need to know what signs to look out for so you’re not stuck without heating and cooling when you need it most. Luckily, there are a few simple signs that let you know when it’s time to replace a component in your HVAC system.

If you have a problem with your furnace or AC that’s going to cost a lot to repair, compare the cost of that repair with the cost of replacing the unit. In some cases, you can spend a little more to get a brand-new furnace or AC. This is especially worth it if your furnace or AC is old and could be nearing the end of its life.

Speaking of the lifespan of heating and cooling systems, that’s another thing to consider. You can’t expect HVAC components to last too long, so it’s not a bad idea to have an air conditioning and heating service expert upgrade you every once in a while. Plus, you’ll save money each month when you upgrade to a more efficient model.

Call Carney & Son

If you want your furnace and AC to last a long time, you need to keep up with seasonal service and stay on top of repairs. For that reason, it’s a smart idea to find a good air conditioning and heating service expert you can count on.

Next time you need maintenance or have a problem with your HVAC system, Carney & Son 72 Degrees is here.
