When your air conditioner quits in the middle of a Lafayette Square summer, you need a tech at your door fast — not a voicemail box. We diagnose and repair every major AC brand, often same day.
AC Repair in Lafayette Square
St. Louis summers bring weeks of 90°+ heat and crushing humidity, and a failed AC isn't just uncomfortable — it's a health risk for kids, seniors, and pets. Our NATE-certified technicians arrive in fully stocked vans ready to diagnose your system on the spot, whether you have a central split system, a packaged unit, or a ductless mini-split. We repair every major brand — Carrier, Trane, Lennox, Rheem, Goodman, American Standard, and more — and we carry common parts for compressors, capacitors, contactors, fans, and refrigerant so most repairs are done in a single visit. You get a clear, upfront price before any work starts, and every repair is backed by our workmanship guarantee.
HVAC in Lafayette Square — Neighborhood Context
Lafayette Square's ornate 1870s–1890s Victorian row houses were built before central HVAC existed, so most systems are retrofitted into tight spaces. Original plaster walls limit ductwork options, making ductless mini-splits ideal for upper floors and additions. The high ceilings common in these homes also mean larger heating loads per square foot than modern construction.

"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."
