  The Best Furnace, Electrical and More. Thank you, All. I have been with Thermall since moving into our home, back in 1980s.

  There was a recent software update to the thermostat and our cooling system wouldn’t turn on. A technician came to the house and easily fixed the settings plus showed us the new features. ThermAll has always responded quickly with technicians who are well trained and very helpful.

  Danielle acted as our service technician for the bi-annual inspection. We valued her meticulous attention to detail and dedication to completing tasks promptly and efficiently. During her initial visit, she examined the crawl space for potential duct leaks, noted minor issues, and offered informed recommendations for suitable solutions. Additionally, she installed a Google Nest Thermostat in an exceptionally timely manner. After nearly five years with another prominent regional company, we transitioned to Thermall and are extremely satisfied with this decision.

  On time, friendly/personable tech. Gave some tips for better efficiency and recommendations for future use. Good communication ahead of the appointment. I'd recommend Thermall to anyone in the greater Yakima area.

  Thermal did a fantastic job with our HVAC system. We are moving into a new house and the ducts were disgusting and the lint trap was really clogged. They spent several hours cleaning everything, inspecting, repairing, sealing, and replaced our thermostat. We are really impressed with their thoroughness and highly recommend them for all your HVAC needs!!
