To make things even better, Manny called the next day and said they could put my unit in on Wed...yay! Summer is no fun without ac in Tucson. Wed. they started at 730 and we're done by 1 15. Manny came in, showed me pics from the unit on the roof, answered my questions, took care of the thermostat and put a new filter in for me. They also removed all of the cardboard etc from the job. Considering how wary l was this job couldn't have gone any better. Thank you Ultra ac and Manny!

Super tech Jacob was prompt, courteous, and very skilled. He gave our units a thorough, gave us insight on status, options, and wrapped up his checks very nicely.

We had a routine, pre-season inspection of our home heating by a "big box" provider. The…read morerepresentative came to the house to inspect and declared our system was leaking carbon monoxide, resulting in him shutting down and locking out the system and arranging a a follow-on visit to propose replacement HVAC systems for our home. Suspicious of this result, we found two highly-rated independent HVAC shops - including ComfortX - to perform their own inspections, neither of which corroborated the CO reading. Likewise for the gas company, who came out and also confirmed no leak. So, the CO panic was wrong, whether intentional or not. Jacob from ComfortX was fantastic! He showed how the CO sensors may provide a false positive reading if not operated correctly. He then showed how to test correctly and that the test confirmed no CO. Separately, he DID identify a problem in the controller board that resulted in intermittent heating, a symptom we had experienced the last few years. He was able to isolate the problem to and perform a repair, and got everything fully functioning by the end of the same day. So, rather than us being shut down and waiting for a quote to replace two HVAC systems, instead, thanks to Jacob and ComfortX, we have two fully inspected and functioning systems and a comfortable home, all for a very reasonable inspection and repair charge. It's a huge relief whenever you find someone competent and trustworthy. I am thrilled to have Jacob and ComfortX in my contractor Rolodex! As an added bonus, our house had two systems that were nonfunctioning since we moved in three years ago: air purification and whole house humidification. Numerous visits from various contractors resulted in versions of "We don't know how to do that" type answers. In contrast, ComfortX explained how these systems worked, described what it would take to get them functional and installed optimally, and they will be soon doing the repair that we have been struggling to get done for years now.

We have now been without AC for 4 days. We have contacted them numerous times, as our units should still be under warranty. They have not even bothered to return any of our calls.

I remembered that Nour did AC so I called him for a second opinion. Turns out it was a bad capacitor and Nour had me up and running quickly and inexpensively. I won't call anyone else. He's done new installs at my moms, my in laws, my dads, and about a month ago at my house. We discussed the odds of my existing 17 year old system lasting the hot tucson summer and decided to be proactive instead of reactive. Nour shows up on time, his quote is precise (no add-ons or unexpected overages), the work he does is immaculate and you can tell he takes pride in his work. He leaves the job site clean. When I got home he was sitting in his truck waiting for the recycler to pick up the old unit. I told him hey I'm home go ahead and take off, you don't need to be here for them to come. He told me that's not how he works and he won't leave until it's gone. If you're looking for an honest, hard working, professional then seek no others.
