We’re willing to bet most homeowners don’t know a whole lot about how their air conditioner works. They know it makes their home cooler or warmer as they toggle the up and down arrows on their thermostats. They also know that when it’s working — especially during the middle of the summer — that’s a really good thing.

 

Beyond that, they wonder how cool air gets from Point A to Point B but usually don’t ask a lot of questions — at least not out loud.

 

Well, our friendly technicians at A&A Air in Argyle, TX, believe there’s no such thing as a dumb question. More importantly, there’s nothing more satisfying than an educated customer. So today’s blog post will focus on that one burning question everyone wants to know: How does an air conditioner work?

 

Drawing heat energy from outside and cooling it for your comfort!

 

Without getting too deep into the weeds, your air conditioning unit has three key parts: the compressor, condenser, and evaporator. The compressor and condenser are on the outside unit, and the evaporator is inside — typically in your attic. We mention this because all three “stations” are pivotal in how heat inside your home is absorbed or rejected.

 

Step 1: Warm air trapped inside your Argyle, TX, home is drawn through a vent and blows over the evaporator coil in your attic, which then absorbs the heat from the air and cools it. From there, a fan blows the cold air into the air ducts so that it can be distributed throughout every room and common area of your home.

 

Step 2: While this is happening, the heat that’s been absorbed changes from a liquid state to a gas and begins its journey toward the compressor. The compressor squeezes the gas, which raises the pressure and temperature of the refrigerant in your system.

 

Step 3: The refrigerant reaches the condenser outside, and the outside air absorbs the heat. This process ultimately lowers the temperature of the refrigerant while simultaneously changing it from a gas state back to liquid.

 

Step 4: Last but not least, the cold refrigerant travels back indoors to the evaporator — and the process repeats itself until the inside temperature reaches the desired level on your thermostat. Your thermostat then tells your AC unit to shut off.

 

Preventative maintenance keeps this cycle running smoothly

 

While simple enough, a lot can go wrong throughout this 4-step process that ultimately keeps your air conditioner from working correctly. This is why preventative maintenance is so important. Sure, everything may be working great right now, but more often than not, the families who stay cool in the summer and warm in the winter are the ones who had their systems professionally inspected, serviced, and cleaned before those peak times of the year become too unruly.

 

The Indoor Air Quality Association lists these essential reasons why preventative maintenance is so important:

 

1.   Prevent costly breakdowns

2.   Reduce energy bills

3.   Extend the life of your system

4.   Stay protected under warranty

5.   Improve your indoor air quality

6.   Improve your comfort

7.   Keep your home safer

8.   Help the environment

9.   Give yourself greater peace of mind
