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.

SEER
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.

Air Conditioner Maintenance in Sierra Vista, AZ 85635

“I scheduled a maintenance visit with Arizona Comfort Systems to service my 12 year old Lennox heating and cooling system. It seems to be working okay but struggled a bit during last summer's record setting heat. The technician, Benjamin C., showed up promptly and did a very thorough and outstanding job checking my system and cleaning various components. As a curious homeowner, I asked a number of questions and he was happy to respond and help educate me better on my Lennox system. He discovered that the capacitor was out of spec and while it could continue to work for a while, it would be best to replace it before it could fail and harm the system. I agreed and had him replace it. At my request, he also checked the CFM "cool" speed on the blower and boosted the setting up a notch while checking the pressures and input/output air temperatures. The cooling performance seemed to work better though checking this again on a hot summer day could probably give a more accurate assessment. In summary, I was very pleased with Benjamin's skill, knowledge, and the friendly high quality customer service he provided. I will be calling on him again for future service visits. I have also been very pleased with Arizona Comfort Systems over the years in helping to keep my Lennox system working well. Thank you!”
