Thermall Story
ThermAll has 160+ years of combined experience in the residential heating and cooling business. We began when our owner, Paul Wyatt, was working for another heating and cooling business and wanted the opportunity to provide better service, value, and experience to his customers. In 1988, Wyatt opened his own HVAC business.
Since that time, ThermAll has grown to serve the greater Yakima and Ellensburg areas and more! Years of experience paired with exceptional customer service has allowed Thermall to grow year after year. We owe much of this growth to our outstanding team of dedicated employees, who value our customers and strive to offer them the best in service, sales, and installation.
We value our team and our customers and believe this is what sets ThermAll apart from other HVAC contractors. We are confident in our service and offer a complete satisfaction guarantee on all of our work. We respect your time and arrive promptly and perform our work efficiently. When you call Thermall, you can rest assured that we will take care of you!

  • Just finished up my ductless heat pump system and couldn’t be happier. Cooper and Jesus did a great job and were a pleasure to work with. They were very professional and tidy. Roland and Terry were also very helpfull getting all the financing in order and helping us learn about what was best for our home and budget. I would happily give these guys more stars if that were an option. Highly recommendable!

  • Had a ranch home with base board heating and wanted to go a electric furnace and pump so we had cooling also for summer. They had to put in ducting and all and did a very good job. Can not wait to see how much we save long term in heating and cooling cost. Our home from the 60's is 2100 ft so needed to update it. Would recommend them for your heating and cooling system.

  • This company was so great! I had a furnace fixed on a rental property. I paid for the service. It wasn’t until 4 months later they realized that it was still under warranty. The company refunded the cost of the repair. Thank you! Thank you! The kindness with which this company conducts business is not the norm. I will definitely be referring people your way.
