What heat pump repair involves
Heat pumps move heat from outdoor air into the house. In winter the outdoor coil frosts and the unit periodically defrosts. A failed defrost control or sensor lets ice build up.
Refrigerant leaks, failed reversing valves and fan motors reduce heating. Dual-fuel systems also depend on the controls that switch between the heat pump and furnace.
Outdoor units need clearance from snow, roof runoff and ice.

Heat pump repair in Marlborough: local context
Marlborough sits where Route 20 meets I-495, with a historic downtown, older neighborhoods of capes and colonials, and newer subdivisions and condo complexes built as the city grew along the highway.
Forced-air furnaces are common in the city's mid-century and newer homes, fueled by natural gas or oil, and many homes add central air through the same ductwork. Older homes may still have boilers, and more owners are adding cold-climate heat pumps.
