Furnace Problems We Fix Every Week in Chicago
Furnace won’t turn on at all. Usually the thermostat, a tripped safety switch, or a failed control board. We check the simple causes first — many no-heat calls are fixed in under an hour.
Furnace starts, then shuts off after a few seconds. The classic short-cycle. Nine times out of ten it’s a dirty flame sensor; the fix is fast and inexpensive.
Blowing cold air. Could be a failed igniter, a gas supply issue, or a heat exchanger safety lockout. This one deserves a same-day diagnosis — some causes are harmless, one is serious.
Banging, screeching, or rumbling. Motors and bearings announce their failure before they quit. Catching it early is the difference between a part swap and an emergency call at 2 AM.
Dust or a burning smell from the vents. Often maintenance-related — we wrote up the causes in why your furnace might be kicking dust into your house.
Heating bills climbing every year. An aging single-stage furnace running at 80% efficiency costs real money in a Chicago winter. Sometimes repair is right; sometimes replacement pays for itself. We’ll show you the math on both.
Oil Furnace Repair and Service
Still heating with oil? We repair and service oil furnaces as well as gas and electric. An oil furnace needs a cleaning every year: a new nozzle and oil filter, a check of the burner and the electrodes, and a clean heat exchanger and flue. Skip it and the furnace soots up, burns more oil and eventually locks out. If yours has shut down, smells of oil or is leaving soot around the registers, call (312) 243-9896. Thinking about replacing an oil furnace? Estimates on new installations are free: request a free install estimate.
Garage Heater Repair and Installation
We install and repair gas garage heaters for home garages and workshops. On a repair call we check the igniter, the flame sensor, the gas valve, the venting and the thermostat. For a new heater we size the unit to the garage and run the gas line and the vent. See what a garage heater installation costs in Chicago.
