Andover climate
by the numbers
Andover's unique heating challenges
About 160 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 Salisbury
First frost typically lands around October 17
Seasonal timing
The median first frost in Andover falls around October 17, matching Franklin. A chimney showing staining or crumbling should be examined before the appliance runs daily after that date.
