Common AC Parts You Must Know

Home » Blog » Common AC Parts You Must Know

Have you ever found yourself in a situation where you can’t get your air conditioning system to turn on? If you have, then you probably tried one of two actions; first, you attempted to inspect the various components of the AC to determine the cause of the issue. After your brief inspection, you called an emergency AC repair technician for assistance. 

But how do you communicate the problem you’re facing? If you’re unsure, don’t worry! This is a common problem that many homeowners face! After all, not many people are experts in HVAC matters. However, to have even the slightest understanding of the repairs and maintenance your AC would need, it is important to know its most key components. In this blog, we will discuss the common parts of the AC, and how signing up for AC repair services will help you take better care of these parts.


Most commonly referred to as the heart of the unit, the AC compressor is a critical component in the air conditioning system. It facilitates the circulation of refrigerant and enables the system to remove heat from the air. By doing so, it keeps the home environment cool and comfortable.

Compressors, especially in the most recent AC models, are built to last. However, they are not immune to problems. Some signs of a faulty compressor are leaky refrigerant fluid, hot air flowing when the AC is set to cool, and loud noises during operation. If your AC doesn’t turn on at all, this may also be the cause of a compressor issue and will need an emergency AC repair inspection.

Evaporator Coil

An evaporator coil is responsible for absorbing heat from the indoor air. It is typically located inside the air handling unit or furnace of the HVAC system, and is usually made up of a series of metallic fins that are filled with refrigerant tubing. 

Because evaporator coils play a crucial role in keeping the home cool and comfortable, it is important to notice signs of repair early. You will know that the evaporator coil is having issues when the AC begins to produce warm air or no air at all. Also, if you notice ice on the coils, you will need to contact an emergency AC repair tech to help resolve the issue.

Condenser Coil

While the evaporator coil is in the inside of the home, the condenser is located in the outdoor unit of the AC unit. It is responsible for releasing the heat absorbed from inside a building, as it works in conjunction with the compressor to circulate refrigerant through the system. If you notice that your AC unit isn’t cooling your home adequately, you may have an issue with the condenser unit. Other common problems to be aware of are frequent cycling, loud noises, and high energy bills.

Refrigerant Fluid

Refrigerant fluid, commonly referred to as Freon, is a chemical substance that circulates through the system and helps to remove heat from inside the home and release it outside. 

The most commonly used refrigerants in AC systems are hydrofluorocarbons (HFCs), such as R-410A, and chlorofluorocarbons (CFCs), such as R-22 (which is being phased out due to its negative impact on the environment). 

The proper amount and type of refrigerant is critical for efficient and effective operation of an AC system. If your AC isn’t producing enough cool air, there may not be enough refrigerant fluid. But if you feel like there isn’t enough airflow, there may be too much refrigerant which leads to frozen coils. Any problems with refrigerant fluids must be addressed by an emergency AC repair tech, because it is a rather toxic substance and handling it requires special training. 


The thermostat is the control center of the entire HVAC unit. Its role is to regulate the temperatures produced throughout the home. If the thermostat is faulty, you may experience inconsistent temperatures. In some cases, faulty thermostats won’t even turn on, which is usually explained by worn batteries or an old, worn out thermostat. Luckily, replacing batteries and the thermostat is fairly simple and doesn’t always require the assistance of a professional.
