Furnace Repair in Lafayette Square
St. Louis winters swing hard — 60° one week, single digits the next — and an older furnace under that stress will find its weak point. Our NATE-certified, EPA-licensed technicians repair gas furnaces, electric furnaces, heat pumps, and dual-fuel systems from every major manufacturer. Because a cracked heat exchanger or a faulty ignition can be a carbon monoxide risk, we start every heating call with a safety inspection before we touch anything else. We stock igniters, flame sensors, blower motors, pressure switches, and control boards for common models, so most heating repairs are completed in one trip. You'll always get a written, upfront price and a clear explanation of what failed and why.
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."
