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.

AC Facts

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 Mountain Air Cooling & Heating, we provide all the services you need to keep your AC running in top-notch shape. Call us at 479-782-4328 for repairs, maintenance, or new-system installation.

Air Conditioner Repair in Sallisaw, OK 74955

“I called Mountain Air just before noon Aug 10. The very nice young lady stated someone would arrive TODAY (unheard of in so many other places). Chris arrived just after 1:00 and was extremely professional, yet friendly and understanding. Chris took about 15 minutes troubleshooting and another 20 minutes replacing the blown capacitor (which he had in stock in his truck). I was not expecting this outstanding level of service. I very highly recommend Mountain Air for all your HVAC needs.”

Air Conditioner Maintenance in Barling, AR 72923

“I have never been as impressed as I was watching these two work together as they performed my annual AC maintenance on the Trane AC unit. I have watched all the maintenance on my AC/Heating over the past 35 years. These two were professional and thorough. You could tell that David was training Joshua and was explaining why certain steps were important to perform the job properly. I never have seen the cover removed by any other AC technician, but these two did that! They also cleaned out debris from inside the outdoor AC unit. These two individuals can return anytime to maintain my unit! I have no doubt that the job will be done right! I have a great confidence in Mountain Air for any of my future business! Thank you very much!”

Went the Extra Mile

“Zach came out to service our A/C unit. He was very friendly and professional. He took the time to explain what was done and what needed to be done. He went the extra mile to make sure we were taken care of and set for the coming summer heat.
We have yet to encounter one of your employees that were not professional and courteous.”
