Chatham Heating & Cooling Company - Chicago's Certified HVAC Repair

In Chicago, with its urban air quality and seasonal debris, we recommend a professional cleaning at least once a year, ideally during your spring maintenance tune-up. Dirty coils force your system to work harder, increasing energy bills and the risk of a mid-summer breakdown.

Common signs include rooms feeling unevenly heated or cooled, your system short-cycling (turning on and off frequently), or the thermostat display being blank or unresponsive. These issues are especially problematic during Chicago's temperature swings. We can diagnose if it's a calibration, wiring, or battery issue, or if an upgrade to a smart thermostat is needed.

Absolutely. Our comprehensive seasonal maintenance is designed specifically for Chicago-area systems. It includes a thorough cleaning of condenser coils, calibration and testing of your thermostat, and a full system check to catch small problems before they lead to costly repairs and uncomfortable emergencies during peak weather.
