Air Conditioning Basics

The four main components to your air conditioner are:

Condenser: The condenser is the outside metal unit where the gas from the compressor is condensed into a liquid. The gas entering the condenser is very hot. The temperature is then lowered, so the gas can convert back to a liquid.

Compressor: The compressor is inside the condenser. It circulates the pressurized refrigerant to concentrate the heat and changes the low-pressure gas to high pressure.

Evaporator: The evaporator is the part of the system inside the home. In simple language, it absorbs the heat from your home.

Expansion Valve: The expansion valve controls the amount of refrigerant in your system.

All of these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is collected in the evaporator, sent outside to the condenser. The heat is removed, and the cool air is recirculated back into your home.

Your Air Filter Needs To Be Checked And Replaced Every Three To Six Months.
(depending on the manufacturer’s recommendations)

A dirty air filter restricts your air flow. This reduces efficiency, costing you money, and over time can put stress on your unit that could result in a costly repair.

Maintenance, Maintenance, Maintenance.
Your air conditioner needs regular checkups to keep it running in tip-top shape. Having annual preventative maintenance performed on your system will prolong the life of your HVAC system and result in fewer breakdowns over all.

At Airheads HVAC, we provide all the services you need to keep your AC running in top-notch shape. Call us at 254-213-5400 for repairs, maintenance, or new-system installation.

Our A/C was up and running within about two hours of making the initial trouble call

“Our A/C went out on a Sunday afternoon. We called Airheads and they had a tech at our house in about 1 hour. Ryan, our tech, was prompt, knowledgeable and professional. He wore a mask, and boot covers when he came in the house. He diagnosed the problem quickly and fixed it. He then made sure everything was cooling as it was supposed to. All said, our A/C was up and running within about two hours of making the initial trouble call. Great work!”
