What Are Inner Components of Your Air Conditioner?


When you get an air conditioner, you probably only think about how it cools down your home and provides you with relief. However, these life savers contain various parts that you should be aware of in case your unit were to break down one day. While technicians such as Morrow Mechanical Inc. can provide you with an AC repair in Spring, TX, for any problem, by having some prior knowledge, you can give them an idea of what to look for.


Air conditioner coils are often constructed of copper or aluminum, and they are frequently finned to improve surface area. This improves airflow around the coils and allows them to transmit heat more effectively.

There are two parts to an AC coil- the evaporator and the condenser. The evaporator is in charge of absorbing heat, while the condenser is in charge of releasing it. To function properly, the coils must be kept clean and clear of debris. Otherwise, the air conditioner will be unable to adjust the temperature in a room appropriately.


Filters are some of the most vital parts of an air conditioning unit. The filter aids in the removal of dust, pollen, and other airborne particles. This improves indoor air quality and helps to prevent allergies and respiratory disorders. A clean filter can also help your air conditioner run more efficiently, saving you money on your energy bill. Filters should be cleaned at least once a month to keep them effective.

Expansive Valve

This valve is essential in the cooling process. The expansion valve is in charge of controlling the flow of refrigerant into the evaporator coil. When you turn on your air conditioner, the expansion valve opens, allowing refrigerant to flow into the coil. As the refrigerant evaporates, it takes heat from the air and cools it. To prevent too much refrigerant from entering the coil, the expansion valve closes. This process is repeated until the appropriate temperature is obtained.

When Does Your AC Need Fixed?

There are a few easy signs to look for when it is time for an air conditioner repair, along with it not giving you the airflow or coolness you are looking for. One sign is if there are strange noises. Hissing or knocking sounds may be an indicator that an inner component is broken or damaged. Another thing to look for is a leak. If something is puddling around your unit, there might be a problem with the refrigerant or that your unit is building up ice from overworking. If your system has an odd odor, there may be issues with the insulation.

No matter the issue, there are HVAC technicians who can take care of it for you. Morrow Mechanical Inc.’s experts can be there for you if you are a resident of Spring, Cypress, or The Woodlands, TX. Though you are not expected to have a full encyclopedia’s worth of knowledge on your unit, having a basic understanding can be beneficial so that you know what may be causing your unit to work poorly. It also helps save your technician time in searching for a problem.
