Claim This BusinessThermAll Heating, Cooling & Electric has served Yakima and Kittitas County since 1988, making it one of the longest-operating family-owned HVAC contractors in the region. With a 4.8-star rating from 697 customer reviews, the company employs a team of trained technicians across its offices in Yakima, Ellensburg, and Cle Elum. Whether you need a furnace replacement, a heat pump tune-up, or indoor air quality improvements, this contractor offers a single point of contact from scheduling through job completion.
One advantage that separates ThermAll from smaller regional contractors is its broad scope of offerings: full HVAC installation and repair, ductless mini-split systems, whole-home air filtration, and a licensed electrical division handling EV chargers, panel upgrades, and standby generators. The company backs every job with a 100% workmanship guarantee and provides free second opinions on diagnoses from other contractors. Customers report that technicians arrive with parts stocked on their trucks, cutting diagnostic-to-repair time down to the same visit in many cases.
Reviewers repeatedly mention technician Mike by name for replacing bedroom fans with flush mount lights, noting his speed and friendly manner. After one customer transitioned from a competing regional company, service technician Danielle performed a crawl space duct inspection during a bi-annual check-up, identified a leak, and installed a Google Nest thermostat in the same visit. Another reviewer credits a technician with diagnosing an 18-year-old gas furnace within 20 minutes and completing the repair before the end of the same day.
Five of six featured reviews give the highest possible rating, with specific technician names appearing in every one-star testimonial as well as all five-star entries. Reviewers frequently mention thorough cleanup after installations, competitive pricing, and diagnostic speed, with one noting they have been a customer since 1990. No negative reviews are visible in the sampled set.
