A broken air conditioner in the middle of summer is more than an inconvenience – it's a health risk, especially for young children, elderly residents, or those with respiratory issues. Stevenson Heating & Cooling provides fast, reliable AC repair services across St. Peters. Our phone lines are monitored 24/7, and we make every effort to accommodate after-hours emergency calls so you don't have to suffer through the heat.

Our diagnostic process is thorough. We check refrigerant levels, compressor function, capacitor health, fan motors, and air filters. We also inspect your ductwork for leaks or blockages. Once we identify the root cause, we provide a clear, upfront estimate before any work begins. There are no hidden fees or surprise charges. We use only high-quality replacement parts, and every repair is backed by our service guarantee.

Preventative maintenance is just as important as emergency repair. Our annual AC tune-up includes cleaning coils, checking electrical connections, lubricating moving parts, testing thermostat calibration, and verifying system efficiency. Regular maintenance not only prevents unexpected breakdowns but also lowers your energy bills and extends the lifespan of your equipment.
