Windham's newer colonials and custom homes have some of the highest heat pump adoption in southern NH — multi-zone systems, ducted cold-climate units, and premium inverter equipment. Premium systems still fail, and when they do, they need a tech fluent in inverter diagnostics, not parts-swapping. That's our lane.
Multi-zone systems dominate Windham, and their failures are usually system-level: one zone dead while others run, communication errors between indoor and outdoor units, and branch-box faults on multi-head setups. Larger homes also expose undersized or poorly balanced installs during cold snaps.
We read manufacturer fault codes, test sensors and boards, and verify refrigerant charge by weight — then give you one upfront price for the repair.
Usually not — single-zone failures on multi-head systems are often a stuck electronic expansion valve, a branch-box fault, or a communication error. All are repairable without touching the other zones.
Yes — we repair all major heat pump brands, including the inverter and multi-zone systems common in Windham.
A properly sized and charged cold-climate system should hold setpoint well below that. Losing ground in the cold usually means a charge, defrost, or control fault worth diagnosing.
