Nashua's median first frost falls around October 19, the same week it arrives in Merrimack and Hollis. A circulator that ran noisy at the end of last season usually gets loud again inside the first stretch of steady heating demand.

Often a worn bearing or a failing coupler, sometimes air moving through a loop that should be solid water. A technician can tell which by where the noise sits in the cycle, and it's worth checking before the pump seizes on a cold night.

Around 5 nights a year, out of roughly 141 total below freezing. That's mild by state standards, but it's still enough to find the weak point in a heat pump running without adequate backup.
It helps. Most of what fails in Nashua in January was already marginal in October, and a technician seeing it early has more options than one arriving after the house has gone cold.
