About us
Built on craft. Trusted by neighbors.
Owner-operated HVAC service in Chattanooga, TN — rooted in honesty, accountability, and 35 years of expertise.
Our story
A local business with a personal commitment.
Assured Comfort Heat & Air opened its doors in 2009, but the experience behind it goes back much further. Owner Ray Belvin brings over 35 years in the HVAC industry — installing, repairing, and consulting on systems of every size across the Chattanooga region.
We built this company on a simple philosophy: be the contractor we'd want to hire ourselves. That means honest assessments, fair pricing discussed up front, and craftsmanship we'd stand behind in our own homes.
Today, we serve homeowners and businesses within a 50-mile radius of Chattanooga — and we still answer the phone ourselves.
