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.

At Red Mountain Air, we provide all the services you need to keep your AC running in top-notch shape. Call us at 480-836-7222 for repairs, maintenance, or new-system installation.

Air Conditioner Replacement in Fountain Hills, AZ 85268

“Great experience! Tim Freidrich was very thorough in his explanation, and details pertaining to replacing our air conditioner needing replacement based on the age of the unit and it’s lack of efficiency. We had received another quote prior to Tim coming out to address our needs, which the quote was mind boggling, and prompted us to seek additional service quotes. Needless, to say we were quite pleased with the installation, and felt very good about going with Red Mountain Heating and Air Condition near Fountain Hills.”

Air Conditioner Installation in Fountain Hills, AZ 85268

“I was in need of replacing my A/C systems as one had gone down and the other two were not far behind. Tim Friedrich and his crew from Red Mountain A/C did and absolutely amazing job in a short period of time.

The system review, discussion and quote was professional, easy to understand and written down. I was immediately impressed with Tim's knowledge and could sense his honesty and commitment to the job at hand. Thanks Tim and your crew at Red Mountain! BTW they also had the best pricing.”

Professional Service in Fountain Hills, AZ

Thoroughness + timeliness + knowledgeability + reliability + economical = professional. Bought a condo in Fountain Hills and while original Trane (20+ years) ac/heater was working we decided to replace it.

Had several estimates done. Tim from Red Mountain came out and his input, questions and inspection outshone all. He was the only one to take the time to inspect the interior and exterior units, return air and grill and to walk around the complex to look at the other units and their upgrades. With Tim’s insight and at a nominal cost, we also enlarged the air return which was one of the best decisions we made. Interior sound was significantly decreased.

While it took a full day, replacement and installation was without an issue. Follow up was done by Tim. It was thorough and provided back up information along with warranty information. Would highly recommend Red Mountain. I will go through them for future maintenance and I will also look at them when my water heater needs to be replaced.

Air Conditioner Repair in Mesa, AZ 85209

“Red Mountain was very prompt in getting me a "reasonable" quote and scheduling the replacement of my AC. Tim was my salesperson and he was excellent, not trying to sell me more AC than I needed. He came back out to test the AC and see how it was working. Thank you Tim. I would highly recommend Red Mountain for all your AC needs.”

Knowledgeable and Informative Service in Fountain Hills, AZ

Our AC was not working in the middle of the night Saturday; after spending most of Sunday trying to self diagnose the issue, we finally called Red Mountain Air. They set up an appointment for an hour away from my call and Bill arrived right on time. Fortunately our issue was not too big nor too expensive. Bill was very knowledgeable and informative and answered all of our questions. We will be recommending Red Mountain Air from now on.

Air Conditioner Repair in Tempe, AZ 85284

“My air conditioning unit upstairs was not blowing any cold air. I had a well known valley A/C company come check it out and basically told me I had to rip out and replace everything upstairs which would have cost me several thousand dollars. I was referred to Tim F at Red Mountain for a 2nd opinion, and thank god I was. Tim F and JD were awesome! They came over and checked it out. With some adjustments, it was fixed same day. Tim and JD explained everything to me, left a map as to how my multi–zone thermostat worked, and were very efficient and professional. Next time I have an AC issue, I know who I am going to call first – the company with a highly competent team that isn't going to rip me off. Thank You Red Mountain AC!”
