Michael Hamblin2025-09-12Trustindex verifies that the original source of the review is Google. Saturday evening, hot and tired, I returned to my condo to find my AC was ka-put. Since I had no previous AC service in 26 years of owning my condo I was immediately distressed. I called Everest Air, good fortune was in my favor, a technician was on his way. A portable AC unit was installed while the team went to work on the new AC installation. The team was knowledgeable and professional but most of all, for me, they were kind and calming. I knew I was in good hands and my distress was relieved. Keith Aronson2025-09-11Trustindex verifies that the original source of the review is Google. Korey and Caesar did an exceptional job.

Ferguc2025-09-10Trustindex verifies that the original source of the review is Google. Caden was awesome. On time, polite and professional. Gave us a fair assessment of our aged unit and insulation but no pressure or scare tactics. Look forward to seeing him again in the Spring.

He did answer all of our questions, we felt very confident to get your services, most for the way he was able and capable to answer all of our questions 🙏🏼, thanks L L2025-09-09Trustindex verifies that the original source of the review is Google. I called Everest after my air conditioning unit went down. Within several hours they had a serviceman on site. In the interim, the company was in touch with me by text message advising the time he would be here and when he was on the way. The serviceman went to work right away and was able to identify and fix the problem in short order. These guys were on point. At every step from making the call to taking care of the problem. Thanks Craig Der Ananian2025-09-07Trustindex verifies that the original source of the review is Google. These guys did a great job on my Attic insulation earlier this year so I tired out their plumbing service for some annual maintenance and to camera scope a pipe. Excellent experience. Professional work. Kept the area clean. Communicated well. Doanh Bui2025-09-06Trustindex verifies that the original source of the review is Google. We have been calling on Everest Air quite a few years now, for every single HVAC need at our home and a couple of rentals we manage. Whether a replacement system, maintenance or a service call, Mark and his team have come right away and made sure the job is done RIGHT! Once or twice, we did not even get a trip charge on something that I did not think would be a warranty item. Who does that? Quality. Responsiveness. Timeliness. Honesty. Communication. Great Customer Service! It is confusing seeing so many HVAC companies and brands out there. Everest Air is like having someone in the family you can depend on. We would recommend no one else to our family and friends…
