No cooling? What to do before calling for service

The “before you call” 8-point checklist
If homeowners are not comfortable checking these items, they should call a technician.

If a/c unit outside is not on at all, check fuse or breaker. If breaker is tripped off, reset.

Ensure furnace filter is clean. If it is plugged with dirt, etc. replace the filter, turn the system off for 2-3 hours and restart.

Check your thermostat. Make sure it is set to the ‘cool’ position and also that the temperature has been turned down.

Check for ice build up. This could be caused by a dirty air filter or thermostat set too low. If there is ice build up, shut a/c off and let the ice melt.

Check thermostat batteries.

Check outside disconnect. When the box is opened, the black piece inside should say ON.

Check exhaust pipe which is located outside to make sure it is clear or debris.

Make sure you removed the winter a/c cover.
