"Juan and his team were top tier professional. From the initial consultation to the hvac installation, they handled everything with care. Juan was so thorough answering my questions, the install was done in time, and everything was to spec. When I contacted him with an issue after install, him and his business partner came to take care of things immediately. I wouldn’t hesitate to recommend them in a heartbeat. So grateful for the work they did with removing our furnace and installing a split unit heat pump. Thank you Juan!"

"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

"I called the number and Diego's wife/receptionist was very helpful and told me she would contact Diego to see how soon he could come check my unit. She followed up with me a few times that day and told me he would be out early Saturday morning. Sure enough abt 9:30am Saturday he showed up and was very friendly and professional. He was quickly able to determine the problem (blown compressor) and within about 30mins had it replaced and my unit was fixed. He was a life saver, because for the next 6 days we hit 100+ temperatures including one day of 108. I definitely recommend HVAC Utor services to anyone needing repairs or replacement, they are very prompt and have genuine concern for helping you."

"Just had the initial diagnostic visit. I was given terrible news (I'll probably end up getting a new furnace $$$), but the technician Ricky was wonderful. He was extremely polite, professional, and friendly. He did a very thorough inspection and then gave me a very thorough explanation of the problems. This included photos he took on the spot of some internal parts (oil leakage, heavy dust & dirt, stress markings).... at no point did I feel like I couldn't trust what he was telling or showing me. He answered every question I had. He went into the "attic" of my Eichler to check the ductwork (via a 14" hole in the closet ceiling, into space so shallow and tight I have no idea how the ductwork was ever even installed), and came out with photos to show me. The company was easy to work with when I had to change appointments, sent me email and text confirmations of everything, and gave me a day-before reminder of the appointment. I had an 8a- 11a window and received a text at 7:50a letting me know the technician was on his way, with a photo of him included. Perfect, perfect, perfect. The visit was $89 but reduced to $39 because I signed up for the MVP membership: $107 for a year which gets me all kinds of free services plus discounts on everything else. It even includes services on my water heater which they did not install! Additionally, they have some really good guarantees, MVP or not. Before leaving he called the office, explained all he'd found, and handed me the phone to set up an appointment with a "comfort specialist". Ariel (on the phone) was also extremely polite, professional, and friendly. These people are trained right! Or they're hiring very well. So, I will be meeting with someone to discuss repairs vs. replacement options. No repair work has been done yet (although Ricky did do a temporary fix that is allowing me to get some heat), so I can't fully review the company. But thus far I'm 100% pleased. This is probably the best experience I've ever had with any kind of repair technician. I've never used them before and have also never written a review before. The experience was just that good. I'll write another when I've finished with them just to give a full review, but so far perfect!"

"I recommend Dooley’s to anyone needing new heating and air, or maintenance. They were prompt and professional. Took the time to explain in detail what I needed and why. I didn’t feel like “just another job”."

"Computer had been acting up for a while but I kept putting off getting it fixed. After reading all the great reviews, I decided to give N.A.T.S. a call. So glad I did. Jim was able to resolve all my problems remotely - no drop off or pick up necessary - so convenient! I feel like I have a brand new computer, it runs so well and FAST too. I couldn't be happier and wouldn't hesitate to use his services again. My only regret is that I didn't call him sooner.

"Called these guys for what I thought was a Nest issue, and they discovered that my heat exchanger had cracked and I was better off replacing my very old unit with a new one. They provided me with a proposal the same day and I decided to contact a couple other companies for comparison. They confirmed Jazz's findings and provided me their quotes as well. Jazz's bid was very competitive and I was happy to give them my business. On install day, Jazz showed up with two other gentlemen and they wrapped up the installation in one day. System works great. Thanks so much Jazz!"
