Why Furnaces Break Down in Winter
Furnaces almost always quit on the coldest night. Here's why — and how to avoid it.
It's not bad luck. Furnaces fail in winter because that's when they work hardest. Here's the pattern in Cambridge.
Why the cold exposes problems
- Continuous running stresses worn parts
- A marginal ignitor or motor finally gives out under load
- Dirty filters choke airflow when demand peaks
Prevention
An annual tune-up before heating season catches the weak links, and a fresh filter keeps airflow healthy.
Book maintenance in the fall to avoid the January no-heat call.
Frequently asked questions
Can maintenance really prevent winter breakdowns?
Most no-heat calls trace to issues a fall tune-up would have caught.
