1 year warranty.When you are paying to have your heating or cooling system repaired, you want it to last. Other companies use the most inexpensive parts and provide the shortest warranty term possible (typically 60 days). Let's face it, you wouldn't warrant something you didn't expect to last.

That's why we use top quality parts, giving us the confidence to back all our repairs with a 1 Year repair warranty.

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 Arizona Comfort Systems, we provide all the services you need to keep your AC running in top-notch shape. Call us at 520-415-5681 for repairs, maintenance, or new-system installation.

Would highly recommend

“Robert not only came out on a holiday for the initial diagnostic but was able to tell us a rough estimate of what could be wrong. Upon getting the parts he worked persistently on our A/C he gave me a step by step on the process and fixed the issue that was caused by previous owners of our home. He was informative and professional. Would highly recommend him.”

Thank you Juan L. for everything and God bless you all AZ Comfort, you guys Rock!

“I ordered the A/C for my home, since I have been living utilizing evaporative coolers to cool down the house for the past 10+ years, at first it was a scary decision as it felt like it was going to be costly and I wasn’t too sure. The prior visits by the AZ Comfort staff Mr. Tomas (who sold me the system) Mr. Nacho Tapia (Who did the initial walk thru to get things rolling) the eased my concerns on getting this done. Then here came the installer the great Mr. Juan L., I can honestly say that in my life I have not met a person so dedicated and passionate for the quality of work he can perform to supersede customer satisfaction, this guy its a true believer or quality work vice quantity of work, a quality trait that in todays market it is seldom to find. Mr. Juan L. from day one, from the minute he arrived he introduced himself and explained everything that was going to happen, and how it was going to happen to develop the picture to answer any concerns, I don’t think I asked a question he didn’t have the answer to it. Then he went to business, Mr. Juan on day 1, he went from nothing to have everything installed and running, he wanted to make sure that, on is first day of work, we could start enjoying our new quality of life and investment. I for sure wasn’t expecting that. On day two he perfectioned his quality of work from day one, because then he stated to detail everything he did the day before, one of my most impressive take away from his was the fact that he could have cut corners on doing his work, but he didn’t wanted to, because then he would feel uncomfortable that he wasn’t providing the best service he was train for. I was amaze with his honesty, professionalism, customer needs comes 1st mentality, and mostly his quality of work. Words do not describe how much I do appreciate the time and dedication he put into installing my A/C system. To me, if every employee in AZ comfort do conduct themselves and provide the same quality of work in the same manner that this team did. Anyone who gets a system installed in their house will enjoy the experience as I did and mostly the piece of mind knowing that we are in good hands for the life of the system. Thank you Juan L. for everything and God bless you all AZ Comfort, you guys Rock! I don’t think that there is competition in the AZ counties that could ever catch up with you guys. Awesome Job!”


Thank you, Gilbert!

“Gilbert was on time, very professional, and got to the bottom of our problem right away. He had the needed part on hand with him and was able to get cool air flowing within our house on the spot. Thank you Gilbert!”
