Our story
Family-owned. Community-trusted. Since 1964.
For over 60 years, Ley Heating & Air Conditioning Inc has been the Inland Empire's most trusted name in heating and cooling — built on honesty, craftsmanship, and neighbors helping neighbors.
How it all started
Ley Heating & Air Conditioning was founded in 1964 by the Ley family right here in San Jacinto, California. What started as a small one-truck operation serving local homeowners has grown into one of the Inland Empire's most respected HVAC contractors — but our values have never changed.
We are a family-owned and operated business, and that means something to us. When you call Ley, you are not calling a national chain or a private equity-backed company. You are calling your neighbors — people who live and work in the same communities you do, whose kids go to the same schools, and who care deeply about doing right by every customer.
Over the decades, we have served thousands of homes and businesses across the Inland Empire. Many of our customers are second and third-generation families who grew up trusting Ley. That kind of loyalty is not something you can buy — it is something you earn, one honest job at a time.

What we stand for
Honesty first
We tell you what you need — not what makes us the most money. If a repair will do the job, we will never push you toward a replacement.
Quality workmanship
We take pride in every job, no matter the size. We do it right the first time so you do not have to call us back for the same problem.
Respect for your home
Our technicians wear shoe covers, protect your floors, and leave the work area cleaner than they found it. Your home deserves that respect.
Community commitment
We live and work in the Inland Empire. We sponsor local youth sports, support community events, and give back to the neighborhoods we serve.
