How Do Home Air Conditioning Systems Work? June 18, 2019

How Do Home Air Conditioning Systems Work?, West Haven, Connecticut

While air conditioning is common in most houses, many homeowners don’t understand how their units actually work. With a better understanding of your home’s air conditioning system, you’ll know when it’s time to contact an HVAC contractor.

What Are the Components of an Air Conditioner?

The components can be found inside and outside of your home. The thermostat is responsible for monitoring air temperature, allowing the system to adjust when necessary. It also allows you to set the temperature to the appropriate level in your home.

The evaporator, which is inside the home, receives refrigerant and cools the air via a fan that blows air over chilled coils. The condenser coil sits outside of the home and is responsible for releasing or collecting heat. The expansion valve is responsible for regulating the flow of refrigerant, and the compressor pump pressurizes it.  

How Can You Tell If Your AC Is Experiencing Issues?

Look for leaks around your unit. It may be refrigerant, which can be dangerous if touched. Conventional water leaks are less serious but can damage fixtures if an HVAC contractor doesn’t take care of the problem right away. 

If you notice strange sounds coming from your unit, it could be a problem with the motor, such as a slipped belt. Also, pay attention to your energy bills. If you notice one that’s higher than normal, your AC may be running inefficiently.
