Why Is My Heat Pump Leaking Water?

In Colorado towns like Wellington, heat pumps and hybrid systems (which use a heat pump and a smaller gas or electric furnace) make an attractive alternative to more traditional heating systems. Heat pumps combine the functions of a heater and an air conditioner into one. Because they’re based on the same technology as air conditioners, heat pumps can experience the same kinds of problems. For example, you might be asking yourself “why is my heat pump leaking water?

The answers are similar to the ones you find with an air conditioner and can include:

  • Ice on the coils. When refrigerant levels are lower than they should be in the system, it can create ice on the evaporator coils. This is problematic because it restricts the cooling process, which impacts the heat pump’s ability to function. (In a heat pump, the outside coils serve as evaporators in the winter and the inside coils do the same job in the summer.) When the ice melts, it can create puddles of water that might leak.
  • Overflow pan or drain problems. Most heat pumps have a condensate pan to collect condensation in the unit and remove it via a drain line. If the drain line gets clogged or the condensate pan is set improperly, the water will run over and cause a leak. This is especially true if the coils get dirty, since the dirt will mix with the condensate and exacerbate any clogs.

Regardless of the cause, if the heat pump is leaking water it needs to be turned off immediately and a repairman called in to fix the issue. In the event of ice formation, he or she can seal the leak and recharge the refrigerant levels. If the problem is in the drain pan, he or she can clear the clogs and/or rest the pan so that it can drain at an appreciable rate. Here in Wellington, heat pumps can be serviced by the experts at Fort Collins Heating & Air Conditioning. We can determine why your heat pump is leaking water, then perform repair operations with speed and efficiency. Pick up the phone and give us a call today!
