Learn moreHazelwood's Trusted HVAC Team
Hazelwood homeowners face real St. Louis weather — 95°F summer heat waves with 70% humidity and January lows dipping below 24°F. That means your HVAC system runs over 3,200 hours per year. When it breaks, you need a local team that knows Old Hazelwood from Hunter's Ridge.
Hazelwood's 1960s-70s ranch homes and the nearby Boeing and manufacturing facilities mean we service both aging residential systems and commercial rooftop units. The flat terrain allows easy condenser placement, and many homes benefit from duct sealing to fix the comfort issues common in original builder ductwork.

- Upfront pricing — no surprise charges after the work is done
- NATE-certified, background-checked, uniformed professionals
- Workmanship warranty on every repair and installation
"Two other companies told me I needed a whole new system. STL Air Pros actually diagnosed a bad capacitor and a dirty coil, fixed both for a fraction of the cost, and told me my system still had years left in it. Finally an honest HVAC company."
