Winchester climate
by the numbers
Winchester's unique heating challenges
About 114 nights a year below freezing, when aging heating systems give out
The oldest blocks in town run heating systems decades older than the newer builds toward Woburn
First frost typically lands around October 30
Seasonal timing
Winchester's median first frost lands around October 30, the same date it lands in Arlington just to the south. A zoning issue that showed up as one cold room late last season tends to reappear right around that point once demand climbs again.

Yes. A mismatched wire count behind the wall plate is a common reason a newer thermostat misreads the room or won't call for heat consistently. It's worth having a technician check the wiring itself, not just the thermostat.
