Most homeowners take their indoor air conditioners for granted. When something goes wrong, however, it can be detrimental to your everyday comfort. Understanding the basics of your AC system and how it operates will help you recognize when to contact an HVAC technician.

How Indoor Air Conditioners Work

What Are the Key Parts of an AC Unit?

Air conditioning systems are comprised of several key components: a condenser, an evaporator, and a compressor. The condenser and compressor are parts of the outdoor system, while the evaporator is situated inside. Each part contributes to a system that utilizes energy to transform liquid into gas and back again to cool the home.

How Do These Parts Work Together?

The AC system depends on refrigerant or coolant circulating through a winding loop of evaporator coils. The process of cooling the home is methodical. Warm indoor air is pulled through the AC, where it blows onto the cold pipes containing the refrigerant. This removes the heat from the air, where it then diverts back into the home through the ducts. The evaporated refrigerant that had absorbed the heat now releases it outside, then quickly converts back into liquid in the AC compressor.

What Do Thermostats & Filters Do?

Thermostats are the control mechanisms that dictate when your AC turns on and off. When they receive the signal for your preferred temperature, the system immediately goes through its evaporating and condensing process to reach that number. Indoor air conditioners can often develop issues if the air filter isn’t replaced. The filter can easily become clogged as air passes through the system, preventing the flow of clean air throughout the home. Replacing them at least every three months can prevent this issue.
