Trusted Southern California HVAC Contractors Since 1958

Weatherite has set the standard for commercial HVAC contractors throughout Southern California for over four decades. Built on our unwavering principles of professionalism, quality, and trust, we’ve earned our reputation by doing things right the first time, every time.

The Weatherite Story

Founded in 1958 by three engineering professionals, Weatherite began as a vision for superior HVAC service. In 1983, our current owner acquired the Los Angeles division, incorporating Weatherite as an independent HVAC company—bringing fresh leadership and an unwavering commitment to quality. Since then, we have grown into Southern California’s most trusted name in commercial HVAC, driven by one simple principle: there is no other way than right.

Today, that founding philosophy guides everything we do. As a union HVAC contractor, we invest in our technicians’ education—five years of formal training—because we believe expertise matters. We’ve pioneered industry technology since 1997, creating custom solutions that benefit our customers. Through it all, we’ve maintained the personal touch that sets our family-owned business apart.
