What matters for heat pump repair in Marlborough
Ice buildup
Some frost in winter is normal. A unit encased in ice that never clears points to a defrost control or sensor fault.
Snow and roof runoff
Outdoor units need clearance from drifts and dripping roof edges, which can freeze over the coil.
Dual-fuel settings
The balance point that decides when the furnace takes over affects comfort and bills. A technician can set it for your system.
