About Gentech Washington
Generator & HVAC Experts
Family-owned and operated, Gentech Washington has been keeping Washington homeowners powered and comfortable for over 15 years.
Our Story
Built on Trust, Powered by Expertise
Gentech Washington Inc was founded with a single mission: provide Washington homeowners with reliable, honest, and expert generator and HVAC service. We've seen firsthand how a power outage or a broken heating system can disrupt a family's life — and we built our company to make sure that doesn't happen to our customers.
From our first Generac installation to the hundreds we've completed since, every job gets the same attention to detail and commitment to quality. We're not a national chain — we're your neighbors, and we stand behind every system we install.
