Avoid Water Damage From Air Conditioning Leaks

Your air conditioning system naturally creates water as a byproduct of cooling your home. The water forms on the evaporator coil and drips into the drain pan, where the drainpipe siphons it off into your home’s plumbing system, or it runs outside and drains into your yard. When something goes wrong, the condensation can drain into your home, where it’s capable of creating significant water damage. 

Keep your A/C draining properly with these tips:

  • Keep the air filter for the air handler clean. When too much dust collects on the filter, it slows the passage of air through the system, and frost can form on the evaporator coil—the part that carries the refrigerant through the air handler. As the frost evaporates, it can flood your drain pan.
  • Clean the outdoor condenser periodically by hosing it off with a light to moderate spray. Remove vegetation from all sides of the condenser and never set anything on top of it. The condenser has to blow away the heat from your home, and anything that slows it makes the whole system run longer, which can also make the evaporator coil freeze over.
  • Have your air conditioning system serviced annually. As part of the service, HVAC technicians check your drainpipe, clean the drain pan and clean all the components of your system. Sometimes debris collects in the drainpipe, like dead leaves, insects or even small rodents, which climb inside the pipes in search of water. The technician can also add an algaecide to the drain pan and pipe to keep the water flowing easily.
  • Have the HVAC technician install a safety float switch inside the air handler. It senses when too much water accumulates in the pan and turns the air conditioner off until the water drains.
