Air Conditioning Basics
The four main components to your air conditioner are:
Condenser: The condenser is the outside metal unit and 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.

An air conditioner doesn’t create cool air.
What happens in the AC process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The warm air runs through the lines and coils in your unit and goes from liquid to gas and back again. During this process, the refrigerant removes the heat and transfers it elsewhere so that when the air comes out the other side, it is cool.
Your AC will remove humidity.
Lower humidity helps the overall comfort level in your home by making you feel cooler, even if the temperature is the same.
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, which reduces efficiency, costing you money, and over time can put stress on your unit and could cause a costly repair.
Maintenance, maintenance, maintenance.
Your air conditioner needs regular checkups to keep it running in tip-top shape. Having regular annual preventative maintenance will bring your system longer life and fewer breakdowns over all.
The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency.
At AA-AIR Company, we provide all the services you need to keep your AC running in top-notch shape. Call us for repairs, maintenance, or new-system installation.
How Much Money Can You Save with a New Air Conditioner?
Our SEER energy calculator can help determine how much you could save on your utility bills. Simply enter your current unit’s SEER value and compare it to a newer, more efficient system. You can even customize it to better match your home’s system for a more accurate calculation.

“Kreigh was the best technician I've ever had in my home. He is naturally very courteous, very competent, highly efficient. I suggest you put him on the board of directors, if you have one. I think you have the most competent staff I've seen, to include Rob in dispatching. I suggest a substantial raise in salary for both”

“Outstanding service from Chris, Kriegh, Pat, Shane and Matt. They were all extremely professional, courteous, knowledgeable, respectful and they explained the entire process. It was a 12-13 hour difficult job, with hours spent in the crawl space on a hot summer day. The owner, Donna, even made an impromptu visit. I would highly recommend this company for any AC needs. Where was Jordan? (An employee joke)”

“John Key has been a knowledgeable, trustworthy, dependable and skilled Workman keeping our heat and air maintained over the years. He let us know within the past few years that our HVAC would need to be replaced. Well, this September our old unit finally conked out. John was helpful in getting us assistance from his co-workers and we now have a new Trane system with which we are quite happy. We look forward to many years of seeing John come out to the house for regular seasonal maintenance. John is the best!”

“Our upstairs air conditioning went out last night. Trying to find someone to come out on a Sunday was hard until we got a recommendation from a neighbor for AA Air. Chris came out and got it fixed in 30 minutes. They were very quick to answer our call and send a technician. The cost was very reasonable. Will definitely use this company again.”

“From the first encounter with AA-Air Co, it has been a pleasure working with this company. The entire staff has been wonderful!! Chris ? came out and inspected our old unit and was honest about what was wrong with it. Then Donna came to do the paperwork to get the installation process started. This was all done over the weekend and above and beyond what we expected for this to be done on a holiday weekend.the installers, Patrick and Shane were super!!! They arrived early and got right to work! After they installed all the components, they showed us how they worked, and even cleaned up the small mess that was created!! It was a great experience all around dealing with this company and I highly recommend their services!!!”
