Family-owned. Customer-obsessed. NATE-certified.
Since 2008, Keller Heating & Cooling has delivered premium HVAC service to over 1,000 Pennsylvania homes and businesses.
Comfort, Honesty, Craft.
We believe great HVAC service should never feel transactional. Every visit is an opportunity to earn a customer for life.
Founded by master technician the Keller family, Keller Heating & Cooling began as a one-truck operation. Today, our 28-person team handles everything from emergency furnace calls to full commercial rooftop installations — with the same craftsmanship and care.
We're proud to serve our neighbors throughout Beaver County, Allegheny County, and Washington County. From century homes in Mt. Lebanon to new construction in Cranberry Township, we bring the same dedication to every job: show up on time, diagnose accurately, communicate clearly, and leave your home cleaner than we found it.
