AIR CONDITIONER

WHY ISN'T MY AIR CONDITIONER BLOWING COLD AIR?

  • Your outdoor cooling coil may be clogged or blocked Debris can easily stick to the inlet side of the cooling coil in your unit. Be sure to clear away any tall grass, sticks, or leaves that may be surrounding your outdoor unit.
  • Your indoor air handler coil could be blocked Ordinary house dust and debris like soot or pollen can block indoor air handler coils. For your indoor air handler, try to wipe away any buildup of dust on the coil and change the air filter often.
  • Your filters may be clogged or dirty Clean or replace the filters. Consult your local Trane Comfort Specialist™ if you are unsure where the filters are located.
  • Your thermostat controls may be set incorrectly Try turning the thermostat off and then on again. Reset to the desired temperature and see if that helps.

WHY IS THERE NO AIR MOVEMENT OR AIR BLOWING FROM MY AIR CONDITIONER?

The air handler might not be working because of a blown fuse or open circuit breaker. Reset the circuit breaker or replace the burned-out fuse. You should also check return grills for blockages that could keep air from circulating freely in the system.

WHY IS MY AIR CONDITIONER CONSTANTLY RUNNING?

Your thermostat could be set too high. Reset your thermostat by turning it on and off, then adjust the temperature to a comfortable level.

WHY IS THE DRAIN PAN FOR MY AIR CONDITIONER OVERFLOWING?

The drain pan below your interior AC unit collects condensation. An electric pump is supposed to move this condensation to a nearby drainage pipe. The pump might have come unplugged or there may be kinks or blocks in the drainage line. Contact your local Trane Comfort Specialist™ if you need help.
