Heat Pump Repair in Aurora

Normal defrost takes a few minutes. The outdoor fan stops, the unit hisses, and steam rises. Problems look different: ice thick enough to hide the coil, ice building on the fan blades, or a unit that runs in defrost so long the house cools down. We test the defrost sensor and board, check that the outdoor fan restarts, and measure refrigerant pressures, because an undercharged system frosts heavily and never quite clears.

Aurora's design heating temperature is about 4°F, and a properly sized cold-climate heat pump should carry most winter days without help. If your electric strips or furnace run constantly, something is off. The heat pump may have stopped producing heat while the thermostat covers for it, or the thermostat may be configured with no outdoor lockout. Emergency heat left on after a cold snap is another common one.

With a gas furnace as backup, check the switchover point. Many systems ship with a conservative setting that hands off to gas earlier than needed, or never hands off because the outdoor sensor isn't connected. Our guide to heat pumps in Denver-area winters covers what a working system should do at different temperatures.

Hail does real damage to outdoor coils on the plains. Flattened fins reduce airflow in both heating and cooling seasons, and a direct hit can puncture a tube. If you file a roof claim after a storm, have the heat pump inspected at the same time and photograph the coil.

The outdoor fan motor and its run capacitor are the most common electrical failures we see year-round. A unit that hums without spinning, or a fan that starts only when nudged, usually has a weak capacitor. It's a quick repair if caught before the motor overheats.

Hoffman Heights' early-1950s houses and the city's large 1970s and 80s neighborhoods mostly started with furnaces and central AC. Where a heat pump has replaced the old AC, the furnace often stays as backup. Newer master-planned homes tend to have newer equipment still under manufacturer warranty if it was registered.

When a repair runs into the compressor or reversing valve on an older unit, we price replacement alongside it. A cold-climate replacement may earn $1,500 through Power Ahead Colorado, which the contractor requests before installation, along with the $1,000 state credit. Xcel's rebate amounts changed in October 2026, so confirm them directly. We pull the permit through the City of Aurora's Aurora4Biz portal.
