Our Story

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 Heating & Cooling, Inc. has grown to serve the greater Yakima and Ellensburg areas and more! Years of experience paired with exceptional customer service has allowed us 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.
