What customers say
"I had Everest Air handle a fairly involved project at my home, including replacing my water heater, installing attic insulation, insulating the header above my garage door, and making several HVAC improvements. This included replacing the roof jack, elbow, and stand, upgrading the ductwork to an over-under drop setup, and adding a new return in the master bedroom to improve airflow and efficiency. As with any large…"
— Reid Gottschalk · Jan 22, 2026 · Google Reviews"Everest Air is great. I recommend them to my clients when they need someone to look at the HVAC during the inspection period. I have personally used their plumbing services to do a tankless hot water heater flush.

They always get back to me in a timely…"

— Kim Anderson · Mar 7, 2026 · Google Reviews"We knew we were going to need a new AC system when we purchased our house in 2020. Everest Air was recommended to us from a close friend and they have been fantastic. Since 2020, our 20-year-old system has been dying slowly but Everest Air has always been able to put a band-aid on it until this last summer (unit finally died). After shopping many different companies (including Costco’s Collin’s Comfort), we went wit…"
