Heat pump repair in Great Falls.

Almost every owner home in Great Falls is a detached house, and these are large ones. A house that size rarely runs on one heat pump. Two is common, three is not unusual, each with its own outdoor unit, its own air handler and its own thermostat. So the useful first move on a Great Falls call is to figure out which zone is cold. Tell us the room, and we know the unit. That is the whole repair, not the whole house.

The age of the housing stock matters. Most Great Falls houses were built in the 1980s and 90s, and with a median of 1986, a house with a heat pump has had that pump replaced at least once and probably twice. The newer replacements bring the usual wear parts at ten to fifteen years, a capacitor, a contactor, a defrost board, and the older ones may still be on R-22 refrigerant, which means a leak is a decision rather than a quick fix.

Great Falls is also where backup heat gets interesting. About one house in twelve heats with propane, and plenty of the heat pump houses carry a propane furnace as the second source. With dual fuel, the thermostat decides which one runs by the outdoor temperature. A pump that is down on a cold day may not feel like a no-heat call because the furnace picks it up, until the propane gets low. If your tank gauge is under a quarter during a cold stretch, tell your supplier before you tell us.

The lots are wooded and hilly. Outdoor units on a slope can sit in a drift of leaves or a patch of ice that never melts, and a driveway that takes a minute to climb is worth mentioning when you book, because we will plan the visit around it. Leaves piled against the coil are a ten-minute clean, not a repair.
