Maplewood 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 Downtown Maplewood from Laclede Station.
Maplewood's 1920s-30s homes on small lots mean compact mechanical rooms and tight outdoor unit placement. Ductless mini-splits are a frequent solution for these older homes, and duct sealing helps fix the comfort and efficiency issues common in original plaster-wall ductwork.

- Workmanship warranty on every repair and installation
"Our 1920s home has a tiny mechanical room and every other company said a modern furnace wouldn't fit. STL Air Pros found a compact unit, did a clean install, and even improved the airflow to the second floor. Problem solvers."
