Tried breakers, etc. Called and they had a guy out to my place within 45 minutes on a Sunday. Now that is fast! Travis did an excellent job. Turns out a wire had fried. Got me back up and running. It was already up to 82 degrees (see photo), so it was not comfortable. It's now blowing cold air again. Thankfully, I won't have to go to the hotel tonight. Keep up the great work guys!

Jason is very friendly, knowledgeable, professional, and detailed. He walked us through everything he was going to do during the energy audit, always asked if we had any questions, and was very thorough in all of his explanations and findings. The service was $99 and it was worth it to get detailed information about our home and how we can improve our energy usage. I will be recommending his services to all of my friends and family that own a home.

It's our second house and rather than waiting years before getting an energy audit this time we did…read morethe thing right and within the first year I contacted Jason who also did the audit in our first house. We had significant issues related to voids, lack of insulation and a very warm bedroom located above the garage. After he came and did the assessment, we came up with a plan to do what we thought were the fastest ROI. We changed all of our ducts to R-8, extended the plenums, increase the insulation level to R-30 and filled up all the voids and air leaks, added a return and put more efficient grills. At the end, our electric bill went down, the rooms were more comfortable and temperature equalized. Jason is really meticulous and really knows its stuff. I would recommend him for new or old constructions. Yes, you read that right, he can tell you if the builder did the right things for your AC or if he took shortcuts which may lead to issues to you as soon as your system is out of warranty. Also, for $99, it's well worth the price!

I had Kilter Mechanical replace my HVAC unit in 2019, and it was one of the best decisions I've…read moremade as a homeowner. Greg, my technician, installed the unit (he even remembers the day because it was pouring rain, yet they did it anyways because it was the middle of winter and my house was absolutely freezing), and every year since, Greg has come out to service the unit, ensuring it runs smoothly and efficiently. The unit was reasonably priced and has performed wonderfully, even during the hottest months in Phoenix. As far as the office team goes, the customer service has always been prompt, courteous, and the team seems thorough in their work. They are honest and transparent, which is something I highly value. Scheduling my annual inspection is always easy, and they offer a maintenance plan that is affordable and convenient. I look forward to partnering with Kilter Mechanical for as long as I own an HVAC system in Phoenix. Their consistent and exceptional service has made them a trusted partner in maintaining my home's comfort.

We decided it was time to take advantage of the SRP rebates to add insulation to the attic of our…read moreolder home. We got estimates from the three highest rated companies. Thermo S and another company's estimates came back close but with very different approaches to cooling down a bedroom that was always hot. In the end, we decided Thermo's solution sounded more logical. In the end we went with Thermo S because of Caden's expertise with duct work. He recommended duct sealing and adding an extra vent in addition to insulation. Day of, the team showed up on time, did the work efficiently, and cleaned up their mess. The difference was instant. The air felt cooler coming out of the ducts, the A/C comes on less, the hot bedroom is cooler, and the house is quieter. I do have bad allergies/chemical sensitivities and the duct sealing was rough but after 3-4 days the smell faded and it's been fine. I would say communication with the office could have been better but they always returned calls the same day. All and all a very positive experience--I would highly recommend Thermo-S.

They called ahead of time to let us know they were on the way. Did the inspection and gave us the cost and we just had them do the job that day. Phil, Erik & Quan were fantastic.

Our AC shut-off on it's own - hallelujah!! We are super excited about keeping our home cooler this summer. THANK YOU GUYS - very much appreciated! Bev Beaudoin

UPDATE Mr. Russo,…read morethe owner of REEis, called me several times; he wanted to talk to me. I agreed to speak with Mr. Russo on Saturday February 28, 2026. He called and asked me what he could do to find a solution that would make me happy. We discussed both units. We paid for new units, but the grilles are damaged and look pretty bad. He said he'd send his best technician, Dennis, to examine the units. We also discussed the electrical panel, which I paid $6,800 for (it didn't need replacing). He agreed to reimburse me $4,800, and he said Dennis was going to bring the check. Dennis came and inspected the units.  I asked him about the check he was supposed to give me.  He said he didn't know anything about it. I sent an email Monday march 9th  to Mr. Russo why he hadn't given me the promised check and how he planned to resolve my issues.   I am still waiting for his response. It's terrible that after agreeing to something there has been no follow-up.  His word is worthless.  This reflects very poorly on the company.   Don't hire this company.  If the owner doesn't keep his promises, what can you expect? I was going to update my review to a positive one if they had honored their word; but he didn't, even after repeatedly asking me what he could do to find a satisfactory solution. Today is Monday March 23th, and I still haven't heard from Mr. Russo.

Exceptional Service from Ian S. and Desert Diamond! I have…read morebeen using Desert Diamond for years (they even installed my new air conditioner a couple years ago) and they have earned my HVAC and Plumbing business forever. Their latest service only solidified why I will never go anywhere else. Ian S. came out to install a water softener system, Reverse Osmosis system, a pressure regulator and some plumbing rework throughout the laundry room for us, and his work was absolutely impeccable. From start to finish, his customer service far exceeded my expectations. He was extremely friendly, personable and so good with my annoying dogs too!! What I appreciated most was his incredible attention to detail. Ian took his time to make sure every single aspect of the installation was perfect, and he left the workspace absolutely spotless. He also took the time to explain everything thoroughly, ensuring we knew exactly how the new systems worked before he left. If you want honest, meticulous, and top-tier service, ask for Ian at Desert Diamond. They truly are the best in the business! And worth every $!
