Clogged Condensate Drain

Heat pumps pull heat from outdoor air and distribute it throughout your home. Heat pumps naturally collect moisture from outdoor air and then expel it through its condensate drain system. With continual use, a heat pump’s condensate drain can become clogged by the buildup of dirt, algae, and other debris. Professional heat pump maintenance can help resolve this issue.

Dirty Heat Pump Coil

A dirty heat pump coil is one of the most common causes of a leak. A cold evaporator coil in every heat pump unit is responsible for removing condensation from the air and draining it from your heat pump. However, if this coil becomes too dirty, it can interfere with the process, preventing the condensation from draining properly. A professionalHVAC technician can inspect and clean your heat pump’s coil to resolve this problem.

Frozen Evaporator Coil

Your heat pump’s evaporator coil can freeze over if its refrigerant levels get too low. As this layer of ice around your evaporator coil melts, you may notice a pool of water forming around your home’s heat pump. Moreover, frozen evaporator coils are inefficient and can cause a severe spike in a homeowner’s energy bills. An experiencedheat pump techniciancan help remove the ice from your evaporator coil and replenish your heat pump’s refrigerant levels. 

Cracked Pan

A crack in your heat pump’s overflow pan can leak water out of the pan and onto the floor around your heat pump. Unfortunately, it’s not uncommon for overflow pans to crack, as constant exposure to moisture causes them to quickly rust and corrode. Luckily, resolving the issue of a cracked pan is fairly simple. If you discover that your pan has cracked, all you need to do is buy a new one to replace the old one with.
