Oakville 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 Oakville from Riverside.
Oakville's 1980s-90s suburban homes are hitting their first replacement cycle, with many builder-grade systems now 15-20 years old. The large lots and hillier terrain toward the river make outdoor unit placement and airflow important, and right-sized replacements with smart thermostats are a common upgrade.

- Upfront pricing — no surprise charges after the work is done
- NATE-certified, background-checked, uniformed professionals

"Our AC went out on a 97-degree day and STL Air Pros had a tech at our house within two hours. Fixed a blown capacitor on the spot, explained exactly what failed and why, and the price was totally reasonable. Won't call anyone else."

Replaced our 18-year-old furnace with a new high-efficiency unit. The crew was on time, professional, and cleaned up completely. They also caught a small carbon monoxide issue with the old heat exchanger — probably saved our family from a serious problem.

I've used three different HVAC companies over the years and STL Air Pros is in a different league. Straight answers, no upselling, competitive pricing. My maintenance plan has caught two small issues before they became expensive repairs.
