Greater Phoenix AC Installation

A high-efficiency unit can save on utility bills, and the right features will curb system wear and tear, but we will never push you into a unit you do not need or want.

If you are considering a new air conditioner, call us for a consultation. We’ll discuss your comfort goals and topics such as:

What Is SEER2?

Your air conditioner’s Seasonal Energy Efficiency Ratio 2 (or SEER2) measures cooling system efficiency. The higher the SEER2 rating, the more efficient the air conditioner.

Discover how much you can save with a new air conditioner by visiting our SEER2 calculator on our installation page.

Compressor Capacity

Single stage, two stage, and variable speed are terms relating to compressor capacity.

  • A single-stage compressor works at capacity. It has “on” and “off” settings.
  • Two-stage compressors operate on a high or low setting, making them more efficient and able to control the temperature more precisely.
  • Variable-speed compressors operate from approximately a quarter of their capacity to 100 percent capacity and everything in between.

HVAC Tax Credits

Tax credits and rebates can help you trim the cost of your new air conditioner. You can claim a 30 percent credit up to $600 through 2032 for qualified high-efficiency air conditioners. Local rebates may also be available.

AC Maintenance

At Desert Diamond Air, we are big believers in regular preventative maintenance. When we tune up your air conditioner, we clean it, restore efficiency, lubricate moving parts, and fix minor problems that might otherwise need costly repairs if allowed to spiral out of control.

Our Desert Diamond Club maintenance plan is a cost-effective approach to equipment upkeep. It offers four tiers of benefits and monthly fees. You choose the level that is best for your budget and comfort goals. We will remind you when to schedule maintenance, and we discount parts and accessories.

Here are three practical AC maintenance tips to keep your home comfortable and efficient:

  1. Remove any vegetation or debris that might block the airflow from your outdoor condenser unit.
  2. Change your air filter routinely for a strong airflow.
  3. Use ceiling fans to improve circulation and add charm to a room!

“I have used Desert Diamond for years, and my latest visit with Ismael didn't disappoint He was very knowledgeable, and thorough in his inspection of my two AC units. This is why I stay with Desert Diamond- competent techs who know their job, are passionate about doing a good job and always are courteous and kind.”
- Bonnie M.

“Thanks Desert Diamond! I've been in construction for over 30 years. Your team came out to do an AC replacement. I can't say enough about what a truly professional job you did. From Bree whom I talked with on the phone to Damien who first came out to Chris and the 2 installers. What a great team! They left our house in better condition then they found it. I hope the owner takes good care of you guys at Christmas! I rent so I can't speak to the price. But would highly recommend Desert Diamond!”

“Deceitful practices, Tech's use scare tactics to convince you urgent work is necessary, then scamming you for huge amounts of money.
– Tech arrived with outdated, non-working equipment that stalled and died during repair. My AC needed refrigerant, a full 5lbs. was necessary to receive cool air in my home. The canister he brought was barely half full and "went dry" during installation and stopped filling at 2lbs. unable to give us the full 5 lbs. necessary, and tech was unable to know exactly how much had gone in so he "guessed" the amount and ultimately charged us over $800.00 for a full 5lbs, which could not be verified. His digital reader that displays the number of lbs. distributed also 'died' during the process, obviously a used and broken piece of equipment that should never have been used. With two pieces of equipment that were not up to standards, there was no way of knowing how much Freon was accounted for, which is where the tech's "guesswork" came into play. He was young & inexperienced and should have called for a back-up tech to come out with properly working equipment to give an honest readout. Instead, he claimed there 'probably' was a Freon leak and would have to tear down the drywall in the garage and check the AC pipes to find the leak, and if I didn't comply, I'd be looking at serious costs ahead. I declined and asked him to leave. He then demanded the $800.00 for what he 'guessed" had transpired, and wouldn't leave until I paid. He openly admitted that the canister he brought was 'not full' when he picked it up earlier. Meanwhile, it's 100 degrees out side, house heating up rapidly with two seniors inside, and we were left with an AC unit that would not shut off at all, only manually. We went to a hotel at our cost to keep cool. This tech literally ruined our AC and we had to call another company the next day to get it fixed right. I called Desert Diamond at 8:30pm that night, left a voicemail of complaint and never received a return call. The General Manager, Joseph Moeller, emailed the next day stating they did nothing wrong and stand by the $800.00 charge. I suspect this GM was probably a low level former tech who was given the GM title as a nepotism favor. WOULD NEVER RECOMMEND DESERT DIAMOND.”

“From the estimate by Craig to the installation with Dyson and Xavier I found all to be professional, timely and easy to work with. I wouldn’t hesitate to recommend Desert Diamond in the future.”

- Dava B.

“Craig came over on time and did a inspection and took all measurements . He explained the different options available and differences so I could understand and make a informed choice. WONDERFUL NO PRESSURE BID ON A JOB i CAN FEEL GOOD ABOUT.”

- Bill F.

“Leo was very nice and informative and explained things that he was doing. He was also very neat and careful in my home which I appreciated. He seems very knowledgeable and efficient.”
