Curious about the inner workings of your AC system components? In our previous blog post, we have already written about some of the components of your air conditioner. This is part 2. After all, when you know how your AC system works and what all the parts and pieces do, you get a unique opportunity to care for it properly.

You can quickly identify how the components should be running and if they’re going wrong. When you know this kind of information, you can keep on top of your system and avoid expensive repair billsAnd you get to stay cool during the hottest times of the year!

With that, let’s dive into the different components that make up your AC system and how they work together to keep you cool and comfortable during those hot summer months.

AC System Components - AC Unit

Air Filters

Let’s start with air filters. 

These little guys play a big role in your AC system’s efficiency as they help remove impurities from the air, such as

  • dust
  • smells
  • pollen
  • and pet dander. 

By regularly changing your air filter, you can improve the air quality in your home. This also helps your AC run more efficiently because the filters quickly build up with pollution, especially in a house with lots of dust or animal hair.

If they do clog up, this can strain your AC system and cause overheating. That’s why it is important to keep on top of keeping them clean and replacing them.

Not sure how often to change your filter? Check your manufacturer’s recommendations, but a good rule of thumb is every 1-3 months.


Next up is the thermostat. 

This AC component is responsible for regulating the temperature in your home. 

By communicating with the AC system, the thermostat determines when to turn it on and off based on your desired temperature. 

Some thermostats even have advanced features like programmable schedules and Wi-Fi connectivity, giving you even more control over your home’s climate.


Quite simply, refrigerant is the chemical used to cool the air in your AC system. 

It’s typically made up of a combination of chemicals that work together to absorb and release heat. 

Without refrigerant, your AC system couldn’t provide cool air for your home. 

However, it’s important to note that refrigerants can harm the environment, so it’s crucial to properly maintain your AC system and promptly repair any leaks to prevent harm to the environment.

Fans and Coils

Fans and coils work together to circulate cool air throughout your home. 

Fans can be found in your AC system’s indoor and outdoor units and help move air across the evaporator and condenser coils.

These coils transfer heat from the indoor air to the refrigerant. Evaporator coils are located inside the indoor unit and absorb heat from your home’s air. Condenser coils are located in the outdoor unit and release the absorbed heat outside. 

Once again, without these coils and fans, your AC system wouldn’t be able to provide cool air to your home.


There you have it – a brief overview of the key components that make up your AC system. 

By understanding how each component works, you can better maintain your AC system and potentially even troubleshoot any issues that may arise.
