From start to finish, the team demonstrated a genuine commitment to doing the job right. Kyle Richardson was excellent to work with, he was knowledgeable, responsive and clear throughout the process.

I would not hesitate to recommend Larson Air Conditioning to anyone looking for a reliable professional HVAC service provider.

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.

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!

He fixed it in an hour, and charged for an hour. Such a relief - no pressure or upselling. Highly recommend.

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.

This is a bit lengthy but deserved. In Arizona, air…read moreconditioning is as important as water. Without it for nine months, you would suffer. We bought a 50-year-old home four years ago. The AC unit was at least 15 years old and struggling. We approached different companies about service and repair; one tech, Sebastian of Reiss Air Conditioning, shined in explaining the challenges of our old system and nursing it through three summers. This summer it would give out, so we asked Reiss for some solutions. They came up with a plan to replace the AC unit and update the old duct distribution system. Such a project would also require installing a new electrical panel, to replace the original. We can report that the project is completed and we couldn't be more satisfied in the work. What made a challenging project attainable? The expertise and customer focus of the Reiss crew. First, every Reiss tech -- Antonio, Phoenix, Marcus, Pablo and Marco -- was professional, on time, conscientious and patient. We set appointments and were reminded the day before and day of. Each respected our home and our time. Second, Jedi and Zane completed the switch to the new electrical box without a problem. They identified unlabeled connections and finished the project with clean tags for each appliance and location. Third, Brian and Stephen at the Reiss main office worked with us on the specs of the project, available discounts, comparable substitutions and problem-solving. They were responsive and straightforward. This was a month-long initiative due to permits, etc. but Reiss led every step of the way. And we were without AC for only half of one day. Finding a trusted partner for crucial home projects can be daunting; we recommend Reiss and the team that served us wholeheartedly.

TERRIBLE - we paid over $2k for an A/C repair, the technician came out as scheduled on Friday early…read moreafternoon, worked on the unit, told us someone would come by THAT NIGHT or the next morning to fix the A/C. NO ONE SHOWED UP, customer service has one woman working (Jenn) who did what she could but she can't contact techs or any of her managers.

Not 24 hours, not excellent care, just a bunch of overpriced services performed by people who do not want to work and do not care about lying to customers. Go anywhere else in the valley. Would give 0 stars if I could.

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 $!
