Built on Trust. Proven by Time.
Randy and Teresa Lazenby founded 1st Class Heat & Air in 2004 with a simple belief: every DFW family deserves an HVAC company they can actually trust. Not a company that sends a stranger to their door. A company that shows up, tells the truth, and stands behind the work.
Â
For over 22 years, that belief has driven every service call, every repair, every installation across 48 cities in the Dallas-Fort Worth metroplex. 5,000+ customers and a 4.8-star rating aren’t marketing numbers — they’re the names of neighbors who called again.
Â
“We’ve always had the heart. We’ve just never said it.” — Randy Lazenby
