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 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.”

“We've had great service from these folks. Previous companies left a trail of problems after their "maintenance ". Not these folks. They are honest and have educated us on how to get the longest life out of our units. I'm very glad we found them!!!”

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!”

Air Conditioner Maintenance in Gilbert, AZ 85233

“Red Mountain was recommended to us by our neighbor who is particular about his dwelling so I basically knew he had done his homework. I had an older system that was hot water heat and that caused some problems with the air conditioning. Since I also found out Red Mountain had done work on similar systems, I felt that they would be a good fit for me. I was not disappointed. They arrived timely, worked hard for several hours, did a great job, cleaned up after and were very professional in the installation. The system appears to be running as, or better than expected. Cooling is faster, system is quieter and I am extremely satisfied. I would recommend them with confidence.”

Air Conditioner Installation in Mesa, AZ 85200

“Our original AC unit, installed in 2005 at time of house construction, was performing poorly the last couple of years and the SRP bill was increasing as a result. After 12yrs it was time to replace the unit, especially since my wife and I had little confidence it would make it through the 2017 summer. This was in mid-April and we didn't want to wait until the heat of summer to get it replaced.

We researched quite a few companies, had some estimates and called Red Mountain as the last one to come out before making any decisions. The sales rep Tim came out on a Saturday morning, early in the time window he gave us for arrival. He even called to say he was nearby and arriving soon. He was, professional, personable, knowledgeable and easy to talk with. After a thorough walkthrough and check of the current system, Tim took plenty of time to explain our system's issues and several options for new units. We settled on a unit that fit our budget and needs. What we really appreciated was that he explained upgrade options BUT did not push to upsell them.

Tim had a crew at our house for the install that Wednesday morning (3 days after the estimate). Two excellent, friendly, professional techs showed up on time and a third joined them within 30 minutes. They were respectful of our home and laid down tarps to minimize dirt, worked hard and knocked the job out in 6.5hrs (with only one short break) and cleaned up perfectly when they were done. Although the install was fairly quick, they didn't rush the job and took the time to do it well.

Tim came out a week later to ensure everything was installed properly and working well. It was! What an amazing difference the unit made in both home comfort and energy savings (cut the bill almost in half from the previous summer). The office also followed up shortly after to check that we were satisfied with the job… and we were… still are!

This company is outstanding with performance and customer service (and pricing) all around, from the office, salespeople and technicians, which is becoming more rare these days. We highly recommend them for any AC needs, whether for a new install or maintenance service.

Thank you so much and keep up the great work!”

Air Conditioner Replacement in Fountain Hills, AZ 85268

“Had a great experience with Red Mountain Air Conditioning when I needed a new AC unit installed. Tim came out quickly and provided a quote that included all the necessary information to make an informed decision… and the price was right. Had the guys out within 3 days to do the install and they were here most of the day, needing to get creative with my install due to tight quarters. My thanks to Rino, Luis and Tony for the extra time and energy they spent on the job and for a job well done. Would definitely recommend them to anybody looking to have an AC replaced.”
