When your car air conditioning blows hot air, the system is failing at one of three jobs: moving refrigerant, shedding heat, ...

Your air conditioning can feel fine one day and then blow warm air the next, with no warning. When that happens, the AC compressor often sits at the center of the failure, because it carries the ...

Low-pressure controls are a common accessory added to many refrigeration systems. They are normally used to electrically cycle a compressor on and off; however, when and why they do so will vary based ...

In principle, air conditioners and refrigeration units don't produce cold air. These systems transfer heat from one place to another and therefore reduce temperature in a confined area (passenger ...

Refrigeration systems with an air-cooled condenser and receiver located outdoors may need to have additional components installed to prevent the low-pressure switch from opening during startup in ...

The compressor is the power unit of the air-conditioning system that puts the refrigerant under high pressure before it pumps it into the condenser, where it changes from a gas to a liquid. A fully ...
