Air conditioner not cooling

Compress effectively with this replacement compressor, part number 18H20, built for select Lennox Air Conditioner, Packaged Unit/RTU, or Heat Pumps.

The compressor might be defective. However, this is not usually the case. Before replacing the compressor, be sure to check more commonly defective components—particularly the overload protector and the compressor capacitor. If the compressor is defective, it should only be replaced by a licensed technician.

Air conditioner compressor won't run

The compressor itself might be defective. However, this is not usually the case. Before replacing the compressor, be sure to check more commonly defective components—particularly the overload protector and the compressor capacitor. If the compressor is defective, it should only be replaced by a licensed technician.

Air conditioner is loud or noisy

When the compressor is wearing out, it generates more noise than usual. When this happens, it is not necessary to replace the compressor—compressors often last for years after they become noisy. However, if you would prefer to have a new compressor, have a licensed professional replace it.

Heat pump not cooling

The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the unit won’t cool. However, this isn’t usually the case. Before replacing the compressor, first check all of the more commonly defective components. If all of the other components are working properly, use a multimeter to test the compressor for continuity. If there is an open circuit, the compressor is likely defective. If the compressor is defective, it must be replaced by a licensed technician.

Heat pump not heating

The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the unit won’t heat. However, this isn’t usually the case. Before replacing the compressor, first check all of the more commonly defective components. If all of the other components are working properly, use a multimeter to test the compressor for continuity. If there is an open circuit, the compressor is likely defective. If the compressor is defective, it must be replaced by a licensed technician.

Heat pump is noisy or loud

The compressor pumps refrigerant through the heating and cooling system. When the compressor is wearing out, it generates more noise than usual. When this happens, it is not necessary to replace the compressor—compressors often last for years after they become noisy. However, if you would prefer to have a new compressor, you must have a licensed professional replace it.

Heat pump won't turn on

The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the heat pump won't turn on. However, this isn’t usually the case. Before replacing the compressor, first check all of the more commonly defective components. If all of the other components are working properly, use a multimeter to test the compressor for continuity. If there is an open circuit, the compressor is likely defective. If the compressor is defective, it must be replaced by a licensed technician.

If all of the other components are working properly, use a multimeter to test the compressor for continuity. If there is an open circuit, the compressor is likely defective.

Heat pump circuit breaker keeps tripping

The compressor is located in the outdoor unit and gets power through a service panel box next to the unit. If the compressor is shorted the fuses in the service panel box or the main breaker box may trip. You can test the compressor for shorts by using a multimeter. If the compressor windings are shorted the compressor itself, or the whole unit, will need to be replaced.
