HVAC in Downtown St. Louis — Neighborhood Context
Downtown's residential stock is a mix of historic loft conversions, mid-century high-rises, and newer condos. Loft conversions often need ductless or high-velocity mini-duct systems because the open layouts and concrete floors make traditional ductwork impractical. High-rise condos typically have individual fan coil units or PTACs that need coil cleaning, thermostat repair, and refrigerant service.

"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."
