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.

We had Comfort Air install our new HVAC system seven years ago and called them when we had an…read moreoutage. The tech came out, fixed it, and then noted our whole duct system was inadequate. We contracted to have it replaced for a little over $9k. The crew who came to work didn't seem to have the full work order and did not provide tarps or anything to cover the mess that fell from the ceiling during the job. We were promised a portable AC unit during the day while the AC was off but that didn't happen either. Our order called for all new vents, but that was news to the crew on site. They did leave and eventually return with replacement vents. The original tech said he would follow up the next day to make everything right, but that's two weeks ago and no word. I'm not 100 percent sure that everything on my work order was installed, but the vents and system are working well. I guess I expected better customer service since we had a great experience the first time. Update: the general manager is following up to investigate our concerns. He was immediately responsive to my review. Hopefully all will be made right.

I have been looking for someone of this caliber for years, no lie, and I am truly grateful for them Tom is a true professional. Knowledgeable, friendly, efficient, timely, reliable, extremely fair pricing and the response time is just like nothing I have ever witnessed. I feel like he is the Superman of Repairs, he can literally fix ANYTHING! Need a new AC unit or HVAC anything? He can. Plumbing issues? Call Tom! Refrigerator issues? Call Tom! Washing machine acting up? Call Tom! Seriously, just call them! I cannot say enough great things about this company. Tom specifically, as he is the only one I have dealt with. Something breaks or acts up, I text him and within mere moments I have a response setting up an appointment. What used to stress me out SO bad is now the easiest thing in the world, thanks to my new best friend, Tom! Thanks Tom, for always taking care of my house and restaurant!

Then when it was reported to the owner, he claimed, "You can't prove it was our fault" and refused to take responsibility. Even though my electrical use went through the roof beginning with their "repair" and didn't return to normal until I discovered the mistake (both A/C and Heat running together) and they returned to fix it. If I had the time and resources I would have filed a lawsuit against them.

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.
