  • Check the float switch near the bottom of your indoor unit. Remove the top of the switch and see if water is present in the switch. If so then a blocked condensate drain line is the most likely cause you may use a wet / dry vacuum to clear the blockage by attaching it to the drain outside and then use it to remove the water from the switch. It is still recommended that you contact a professional so that they can properly clean the drain line and the condensate pan as well as check for other problems.
  • Check the circuit breakers for any that have tripped. To reset push the breaker all the way to the off position and then back on. If they trip again do not continue to attempt to reset them as this is a sign of a more serious issue.
  • Look for disconnects near the indoor unit that may be turned off. Many systems have disconnects that look very much like a common light switch.
  • Look for places where the control (thermostat) wire may have been damaged by a lawn mower or other lawn maintenance near the outside unit. This is very common and usually results in a blown low voltage fuse.

  • Look for signs of ice forming on the large insulated line coming out of the indoor unit, you may also see ice forming on the lines of the outdoor A/C unit. If so, first check you air filter and if it is very dirty remove it. Shut the system off with the fan in the on position at the thermostat and place towels around the indoor unit as it may leak water as the system defrosts. Do not install a new filter for at least 4hrs as the indoor coil will need time to completely defrost. Once the system has fully thawed it is safe to install a new filter and run the system.
  • It the frost returns, it is highly recommended that you contact a professional for a service call as soon you as you notice the frost. This can reduce the chance of water damage and reoccurring problems.
