Important Things to Know About Your Air Conditioner Compressor

Have you ever assumed about how your air conditioner keeps your Whitesburg, Kentucky, home cool? An air conditioner eliminates heat from the air inside your home, sends the heat outdoors, and recirculates afresh cooled air throughout your house. Learn how the compressor, an indispensable module inside your air conditioner, functions and the upkeep required to keep it working.

air conditioner’s compressor and regular HVAC system repairs

The compressor is one of the most significant parts of your air conditioning unit. Not only does the compressor play an imperative role in the cooling procedure, but it also guarantees that the unit works efficiently and repeatedly. To understand how your Baltimore, Maryland, air conditioner compressor works, you should know about its location, function, conservation, and repair needs. Once you do, you’ll understand the connection between your air conditioner’s compressor and regular HVAC system repairs.

What is an AC Compressor?

The compressor in your air conditioner or heat pump is the “heart” of the unit. It is the part that pumps refrigerant, aka Freon, through the system. By the way, Freon is a brand name. But it is commonly used for any type of refrigerant, like Kleenex or Ketchup.

Your AC or heat pump system has an indoor coil, outdoor coil, and a set of lines linking the two. The compressor is the piece of apparatus that cycles refrigerant from the coil to coil through the line set. It is positioned in the outdoor unit, which is technically called the abbreviating unit.

The Role of the Compressor

When refrigerant overrudes an air conditioner’s evaporator, it takes the form of low-pressure gas. To relieve the heat the refrigerant has engrossed. The refrigerant needs to be in an advanced temperature, higher pressure form. The compressor packs molecules in the gas-based refrigerant strongly together, a process that raises both the temperature and pressure of the refrigerant. Since heat moves from warm to cool surfaces, the heat that’s now in the high-temperature refrigerant moves to the cooler air outdoors where it can be unconfined through the condenser.

Compressor Location

The compressor can be originated in the outdoor air conditioning unit, at the rear, or on the side of your home. Other essential parts within the outdoor unit contain the condenser, condenser coil, and fan.

The outdoor unit connects to the indoor part of your air conditioning system through a copper refrigerant tube. Once connected, these two parts work composed to absorb hot air from inside your home and convert it into cool air.

Common AC Compressor Problems

The good news is that AC compressors are pretty hard-wearing. Because they are the heart of the condensing unit and so luxurious, manufacturers can’t afford to put “junk” in their units. Their standings would be damaged quickly.

The bad news is that when a compressor does go bad, it often spells the end of the life for the whole unit since replacement is so expensive.

Compressor Function

To appreciate how the compressor works, think about the cooling process for a split-system central air conditioner. The air conditioner pulls heat out of the air in your home, cools it over a set of cold pipes (an evaporator coil), and issues the cool air into your home. The evaporator coil leftovers cold thanks to a liquid refrigerant that absorbs hot air and changes it to gas. This gas is then ecstatic outside to the condenser coil where the gas again converts a liquid. From this point, the cycle continues.

How does the compressor fit into the picture? The compressor is answerable for moving the refrigerant between the evaporator and condenser coils, guaranteeing that the refrigerant changes to gas or liquid as needed. You can think of the compressor as the heart of the air conditioning system and the refrigerant as the blood. To this end, the compressor pumps the refrigerant through the system to keep it alive and running appropriately.

Compressor Malfunction

The compressor has many moving parts and is easily vulnerable to breaks. If the compressor breakdowns for any reason, the result could be noises coming from the unit, deficient cooling, or hard starts.

Noises coming from the unit: You may hear hitting or clanking noises if a loose part is inside the compressor. Bubbling and hissing may indicate that the compressor has a refrigerant leak. Keep in mind that a transitory noise at startup is often normal for compressors.

Insufficient cooling: When the compressor is loose or worn, the air conditioning unit will not cool your home accurately.

Hard starting: If the compressor fights to turn on or off, “hard starting,” this problem could be the result of an electrical problem with the air conditioning unit.

Other significance of a malfunctioning compressor include the outdoor unit running hot, the compressor burning out, and the air conditioning system not working at all. If you think you have a problem with your compressor, contact an AC expert to help you out.

Compressor Maintenance

Maintaining the compressor is vital for the overall functioning of the air conditioning unit. However, don't make an effort to maintain this part yourself. During a service promotion, your HVAC technician will check the compressor for any apparent damage or failure. Your service tech may also check the compressor packs to make sure that the unit does not have any electrical problems which could touch the compressor.

Compressor Repair

If your compressor malfunctions, your reparation options may be limited. Always contact your HVAC technician for any repair decisions. Sometimes what appears to be a broken compressor may essentially be a malfunction elsewhere in the unit. Ask your service tech for more information.

However, if the compressor is to blame, an emergency may be your only option. Depending on the problem’s severity and the system’s age, you may need to replace your HVAC system entirely.

To keep your air conditioning system working properly, the proper functioning of your air conditioning compressor is decisive. If you need air conditioning repair or maintenance on your compressor or any other part of your HVAC system, contact one of our helpful service professionals at

Only a licensed HVAC service specialist should accomplish any tune-ups on your air conditioner’s compressor. During an air conditioning upkeep visit, our service technicians will check the refrigerant levels to make sure enough refrigerant is present. Running your air conditioner with too little refrigerant can put stress on the compressor. Over time, this stress could cause the compressor to fail.
