Hi-Desert Air handles all of our seasonal tune-ups, including both our HVAC system and our swamp…read morecooler (evaporative cooler). They replace our pads and calibrate the swamp cooler every year and are clean, efficient, easy to work with. Brandy always does a great job setting us up at a time that is convenient and solves any minor problem immediately. They even winterize the swamp system and reboot it come spring with fresh filters--no fuss, no mess. Three trucks showed up one afternoon, got everything done before lunch, and left with no traces behind . If only every contractor could be that efficient! A few years back they replaced our entire HVAC system and our electric bills dropped by almost 40%, and the system has never given us a moment of trouble. They didn't stop at the unit--they replaced our old ductwork with a high-efficiency ducting system. The airflow is reprioritized (they explained that's why some rooms were always hot and some were always cold), and the temperature throughout the house is noticeably more even. Great design, skilled installation. There prices are always competitive and they were will to work with us to get the most out of the limited budget that we had.

They were able to get to the house on Monday morning right on time and ready to go. The repair was done quickly and correctly. He showed me the broken part that he removed and charged me less than I expected - frankly. (Google estimated my repair between $250 and $350 and high desert was shy of $200). I'm happy to recommend this business.

On top of that, Pat saw that the housing on the same unit was cracked in a few places and the door did not open/close smoothly. Pat made 3 trips to get it right, because he wanted to do the right thing for me, as if it was his own unit that needed repair. Emma in the office was always professional and helpful and friendly, so she gets a thank you mention as well. Diversified has my business....thank you!

I contacted this company for a second opinion on an issue with my HVAC unit. When I called to…read moreschedule, I was told it would be a $75 diagnostic fee and $70 per hour for labor, which was cheaper than another company I had already spoken with. That is the only reason I chose to have them come out. The technician arrived, diagnosed a completely different issue than what the first company had told me, and then quoted me $450 + diagnostic cost + coolant cost for the repair--even though he had already found the leak. When I asked how it could possibly cost that much if their labor rate was $70 per hour, he said the office would call me to explain. When the office called, I was told that the $70 per hour was a "warranty price" and that for this issue it was a different price per hr. At no point during the initial call was this distinction made. I was understandably concerned about the lack of transparency, and when I repeatedly reminded them that I chose their company because of the hourly rate they gave me, the person on the phone became rude and defensive. I then asked to speak with the owner. When he called, I explained the situation from the beginning. Instead of listening and trying to resolve the issue, he became rude as well and said to me, "Under any circumstances here are you wrong?" I was shocked. I told him that his company had quoted me one price and then changed it after I'd already scheduled and had the technician come out, wasting everyone's time. He insisted that their labor price had "never" been what I was quoted, yet he had no explanation for why two different people from his own company had told me that number. When I asked directly what their actual fee was, he still would not give me a straight answer. The lack of transparency about pricing and the dismissive, disrespectful attitude from both the office and the owner were absolutely unacceptable. I was treated as if I was the problem simply for questioning a bait-and-switch type situation. I would not recommend this company to anyone who values honesty, clear communication, and basic respect.
