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.
