The heat pump is a hard-working comfort appliance. It puts in more work than a standard air conditioner or a furnace because a heat pump runs in both winter and summer. When it’s cold, a heat pump draws heat from the outside to warm the house. When it’s hot, a heat pump draws heat from out of the house to cool it. It uses the same components no matter if it’s in heating or cooling mode, so these parts can wear down rapidly over the years—twice as fast as an AC or a furnace.
The best way to keep a heat pump from succumbing to all this strain is to schedule maintenance twice a year, in spring and fall. Nothing can prevent every potential problem with a heat pump, however. We’re going to look at some of the more common troubles a heat pump may run into that will require calling experts to repair it.
