Heat Pump Repair in Westminster

The reversing valve is what makes a heat pump a heat pump. It redirects refrigerant so the outdoor coil collects heat in winter and rejects it in summer. When it fails or sticks, a heat pump blows cool air in heat mode, or gets stuck partway and does neither job well.

Not every cold-air call is a bad valve. The thermostat has to energize the valve's solenoid in the correct mode, and wiring mistakes are common after a thermostat replacement. A failed solenoid coil is a quick fix. A stuck valve body is a bigger job, requiring refrigerant recovery, brazing, a vacuum and a recharge. On an older system, that cost often leads us to price replacement alongside it.

Downslope winds can roar across the western edge of the city. They pack snow into outdoor coils, throw grit and debris into the fan and can nudge a unit off its pad. A heat pump that can't breathe frosts heavily and leans on backup heat. After big wind events, check the unit for a clear coil, level cabinet and undamaged fan guard.

Hail is the summer risk, and it damages the same coil the heat pump needs in winter. If a storm hits your roof, have the heat pump inspected too. Fins can often be combed straight; a coil with punctured tubing has to be repaired or replaced, and insurers generally want photos and a contractor's written assessment.

About 10% of homes here are townhomes, where outdoor units often sit in a row on a shared pad or side yard. Close spacing can let one unit's cold exhaust blow straight into the next one's coil. Units in corners collect drifting snow.

Some townhomes use electric strips rather than a furnace for backup. When the heat pump quits, the strips carry the whole load and the bill climbs fast. If your thermostat shows auxiliary or emergency heat for long stretches, call us. See our dual fuel guide for how furnace backup compares.

The Westminster Building Division handles permits for replacement. Most electricity in the city comes from Xcel, though United Power serves some addresses. Xcel's rebate amounts changed October 1, 2026; confirm with your utility. If you replace with a cold-climate model, we can pre-apply for Power Ahead Colorado's $1,500, and Colorado's credit gives you at least $333 off the invoice. The federal credit is no longer available.
