An air conditioner clutch that repeatedly engages and disengages is usually an indicator that the vehicle's system is low on refrigerant. AAMCO recommends having the system checked and charged, as operating an air conditioning system in this condition causes further damage.Continue Reading
Air conditioners operate as a closed system. The same refrigerant cycles through the system many times. Air conditioners have sensors that determine the pressure and temperature of the refrigerant, starting and stopping the compressor by engaging or disengaging the clutch. As the vehicle ages, the system sometimes develops a leak. The reduced pressure causes the switches to misread the pressure of the refrigerant. Leaks allow moisture to invade the system as the coolant leaks. The units include a dryer to catch moisture before it causes the compressor to fail. Operating a leaking air conditioner has the potential to overload the dryer, resulting in system failure.
Automobile air conditioners work much like those used in homes. The greatest exception is that a belt from the car's engine powers the compressor. The compressor transforms the refrigerant from a gas to a liquid. As the liquid expands back into a gas and passes through the system's evaporator's coils, it cools the air and reduces the humidity in the cabin of the vehicle.Learn more about Heating & Cooling
A separate outside compressor and condenser unit is used with ductless split system heating and cooling installations. Ductless operation requires a wall-mounted indoor evaporator and blower unit. One outside compressor can service multiple wall units in a split system configuration.Full Answer >
In order to troubleshoot a standard air conditioning system, the control unit should be inspected, as well as the breaker, outside fan, compressor and other main components. The refrigerant lines that run into the house should also be inspected to ensure there are no leaks in the system.Full Answer >
A central air conditioning system consists of two main components: an indoor air handler and an outdoor compressor. The air handler contains an evaporator coil and a fan to force air over the pipes, while the outdoor unit contains the compressor, a condenser coil and an exhaust fan.Full Answer >
A mini-split air-conditioning system has an outside air compressor like a central air conditioning system, but the evaporator system is located in the room it cools, eliminating the pumping of cooled air into the room through ducts. With more than one evaporator unit, the system is considered multi-split.Full Answer >
