Furnace Problems Common in Arlington Heights Homes
Arlington Heights has one of the most diverse residential building inventories in the northwest suburbs. Post-war bungalows, mid-century split-levels, and contemporary new construction all coexist within the same school district boundaries. That range of home ages translates into a wide variety of furnace types and failure modes:
- Cracked heat exchangers in pre-1990 furnaces: Older natural-draft and induced-draft furnaces in Arlington Heights’s established neighborhoods are reaching the age where heat exchanger fatigue becomes a real concern. A cracked heat exchanger can allow combustion gases, including carbon monoxide, into the living space. We perform visual and camera inspections and will flag this issue immediately if detected.
- Ignitor failure in electronic-ignition furnaces: Hot-surface ignitors are the most common failure point in modern gas furnaces. Silicon carbide and silicon nitride ignitors become brittle after thousands of heat cycles and eventually crack. Homeowners notice the furnace clicking on, attempting to light, then locking out after three tries.
- Inducer motor burnout: The draft inducer motor clears combustion gases before the burners ignite. When it fails, the pressure switch never closes and the ignition sequence halts. A grinding or high-pitched whine from the furnace cabinet typically precedes total failure by a few weeks.
- Flame sensor fouling: A dirty or oxidized flame sensor tells the control board that no flame is present even when the burners are lit. The board shuts down the gas valve as a safety precaution, usually within a few seconds of ignition. Cleaning or replacing the sensor is a fast and inexpensive repair.
- Blower motor bearing failure: Arlington Heights homes with furnaces running 12 or more years often develop blower motor issues. Worn bearings produce a persistent humming or rattling sound, and the motor eventually draws excessive amps before stalling entirely.
- Pressure switch errors: The pressure switch verifies that the inducer motor is producing adequate draft. A cracked hose, a blocked condensate drain in high-efficiency models, or a weakened switch diaphragm can all generate a pressure switch fault code on the control board.
- Thermostat wiring degradation: Low-voltage thermostat wiring in older Arlington Heights homes can become brittle, develop shorts, or lose continuity at terminal connections, causing intermittent heating failures that are difficult to reproduce.
