5 furnace problems Ann Arbor homeowners report when cold weather hits
Common furnace problems in Ann Arbor stem from long, cold winters and an older home stock that force extended runtime, stress components, and expose aging flues and vents to freeze‑thaw damage. These conditions increase ignition failures, heat‑exchanger cracks, motor wear, short cycling, and vent blockages.
- Ignition or pilot failures. Continuous heavy runtime during Ann Arbor winters wears ignition modules and pilots, causing intermittent starts or no heat at all.
- Cracked heat exchanger. Extended high-load operation during cold snaps in Ann Arbor can cause metal fatigue in older exchangers, creating safety and efficiency issues.
- Blower motor burnout. Long duty cycles typical of Ann Arbor winters accelerate bearing wear and motor overheating, which can stop airflow suddenly.
- Short cycling. Older homes in Ann Arbor often have oversized or poorly matched furnaces, and frequent temperature swings cause rapid on/off cycling that stresses components.
- Blocked vents and flues. Snow, ice, and freeze‑thaw accumulation around exterior terminations in Ann Arbor can restrict combustion air and exhaust paths, triggering safety shutoffs.
