Make sure all the registers in the house are wide open. Then be sure the furnace filter is clean. Then go outside and clean off the condenser coils (Photo 2). If several registers were closed or the filter was clogged, the reduced airflow could have caused the evaporator coil to ice up and stop cooling your home.

Ensure the thermostat and front panel are not obstructed by drapes or other objects. Check that the condenser coil is not obstructed with leaves and that its fins are not damaged or bent; repair bent fins with a fin comb. Have the unit serviced and checked for a refrigerant leak if performance continues to worsen.

The most common cause of window air conditioners icing up is a lack of adequate air flow. Room air is drawn over the evaporator coils where it is cooled and then re-circulated back into the room. Insufficient air flow over the evaporator coils will cause them to become too cold.

If the refrigerator condenser coils are dirty, then the refrigerant running through the coils cannot lose heat easily. ... Dirty condenser coils cause the compressor to overheat. Overheating causes the compressor to stop working, and therefore, the entire refrigeration process stops as well.

First make sure there is power to the indoor unit and that a switch or breaker isn't off. ... Try setting the thermostat fan switch to the "on" position. Feel for air coming out of the vents. If it is in the air conditioning mode, check for ice around the evaporator coil and on the refrigerant lines at the indoor unit.

If your air conditioner is low on refrigerant, then your air conditioner can freeze up. This is due to lower pressure inside the system itself. ... As your air conditioner's evaporator coil drops below freezing, the moisture in your air will freeze as it comes into contact with your coil causing it to ice up.

Reasons your AC trips the circuit breaker. If the air conditioner is the source of the tripping, it may be overheating. When an air conditioner overheats, it draws more amps (a measurement of electrical current) from the circuit. ... 2) Dirty condenser coils: The condenser coils are in your air conditioner's outside unit.
