Garfield Heating and Cooling: Reliable HVAC Services Serving Chicago, IL 60609

Warning signs include a yellow burner flame (instead of blue), soot around the furnace, excessive moisture on windows, and a stale, stuffy smell. The most critical step is to install working CO detectors on every floor and have your furnace professionally inspected annually by a certified technician, especially before each Chicago winter. We perform thorough safety checks that test heat exchangers and venting to ensure your family is protected.

This is a common issue in older Chicago homes. Often, it's due to incompatible wiring (like lacking a 'C-wire' for constant power), voltage fluctuations, or incorrect installation settings for your specific furnace or boiler. Our experts diagnose the wiring, configure the thermostat for Chicago's temperature swings, and ensure it communicates properly with your HVAC equipment to prevent inefficient short cycling and restore reliable control.

Our Chicago-specific tune-up goes beyond basic cleaning. We meticulously inspect the heat exchanger for cracks (a primary CO source), test and calibrating the gas valve and burner assembly, check all safety switches and flame sensors, ensure proper vent drafting, and measure carbon monoxide levels in the exhaust. This proactive service not only improves efficiency but is your best defense against the dangerous leaks that can occur as furnaces age in our climate.
