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.

A great bunch of guys

A great bunch of guys. They really know what they are doing. I won’t use anyone else work on my air conditioning system. They installed an air cleaner and an ultraviolet system that has helped myself and my wife with our allergies. Thanks again Kevin and Mike.

I definitely recommend their fast and efficient service.

It’s great when you get professional help during an extremely hot summer. I called them this morning and they serviced our house this afternoon. Our technician Michael answered all my questions and explained things to me that I didn’t understand. Since 2005, one of our bedrooms was always the hottest during the summer and the coldest during the winter, but thanks to his expertise and adjustment that has made on the dampers that leads to the bedrooms we are able to feel that the temperature has balanced out throughout the house. Michael also gave me recommendations on what types of filters that are good for my unit when the time comes for me to change it.

Overall, I am pleased on the work conducted to our HOME AC unit. Thank you!!

To those who are reading this, I advise you to conduct preventive maintenance procedures on your homes so you don’t find yourself on the same predicament as me.

I definitely recommend their fast and efficient service.

He looked professional in spite of the late hour call. He carried himself in a professional matter and did an outstanding job describing my AC issues and worked efficiently and quickly to resolve my AC issues. Thank you Kevin!! You earned a customer for life.

Highly recommend!

Let’s see, where to start. I phoned this company after another local place flaked out, leaving me smoldering in a crazy hot house. I spoke with the owner, and he manage to get me into a slot that same day. The technician showed up a little later than expected, but never once was I left out of the loop as to his ETA… Something a lot of companies don’t do for you . I didn’t feel like I was being forgotten . When Kevin started up the diagnosis he was extremely educated, and made sure to let me know exactly what was happening, and what to be expecting out of the pieces that he needed to replace . Knowing absolutely nothing about HVAC systems, he took the time to explain to me the in and out or workings of each component of the machine, and why it is so important to regularly maintain them . I felt completely confident in Kevin, and his knowledge of the system. He was extremely thorough, and made sure to show me each part/piece that was not doing what it was supposed to. At the end of the service I felt more educated about my central air system, and I felt a satisfaction of knowing that the job was done well. Thanks again! Highly recommend!

Thank you so much!

Kevin did a great job of diagnosing and then fixing our aging a/c system. He was here in a timely manner, very efficient, and had the a/c running. Thank you so much!
