How to save my auto air conditioning compressor? Suction ends when the piston reaches bottom dead center. Because more of the downward stroke is used for expansion, less of the stroke can be used for suction.
These gases have to expand to a pressure just below the suction pressure before the suction valve will open. Low suction pressures also cause the high-pressure gases caught in the clearance volume of the compressor to expand more during the piston’s downstroke.This gives the compressor a lower volumetric efficiency. When the suction pressure goes below normal, the vapor that the compressor is pumping becomes les dense and gets thin (sometimes called rarified vapor).The compressor performance declines. Overcharged or improperly vacuumed auto ac systems will create high system pressures and therefore high temperatures.Ĭompressor pressure plate and rotor pulley excessive air gap will cause slippage and rise in temperature.Ī dirty evaporator will cause the suction pressure to drop. Leaking air conditioning systems will leak out refrigerant and the oil that resides inside of the compressor creating a huge frictional resistance between the compressor piston and the cylinder leading to an increase in compressor internal temperature
The properties of the bearing grease will be changed by this oil contamination causing it a poor compressor bearing lubrication and inevitably internal bearing failure. Seal could cause the compressor oil to finds it way into the hvac compressor clutch bearing contaminating the grease. The bearing loses its grease and in the process, before it locks up completely it gets rough and noisy. Slipping compressor clutches can generate temperatures as high as 1,200 degrees Fahrenheit this tremendous amount of heat will quickly melt down the bearing seal. Always add oil through the oil service port if it comes with one or compressor damage may result.Įxcessively high temperature and lack of lubrication are the biggest enemies of any automotive a/c compressor bearings. Oil could be added through the ac compressor oil service port or through the low side or intake of the compressor. Installing the ac Compressor without balancing the oil in the system, gives a high risk of liquid lock, due to too much oil in the A/C system! When adding oil to the ac compressor in your car one out of two methods could be used and the right one will depend on the type of compressor. PAO-oils do not mix well with PAG-oils and with refrigerant R134a or R1234yf, leading to poor lubrication and increased wear. This is because universal oils are PAO-oils or mineral oils with a different viscosity to that of synthetic PAG-oils. The use of incorrect oils, such as universal oils or oil mixtures, inevitably leads to seizure and damage. Technicians are now beginning to realize that low evaporator pressures cause high compression ratios.)Īnalysis of Denso A/C Compressor warranty claims shows that in a quarter of all cases

Landrigan Auto Pro's pro mechanics know that even the smallest gaps can cause serious damage to your car's cooling system and engine.What causes an air compressor to lock up? We use kits with a "Rapid Seal" designed specifically for your compressor.It includes car AC compressor, accumulator and any needed expansion devices. We use a replacement kit assembly designed to meet or exceed OE function.Landrigan Auto Pro uses AC compressors that are durability-tested for high heat conditions.What To Expect When Landrigan Auto Pro In Indianapolis Replaces Your AC Compressor This pressure forces the liquid out of the compressor and through the cooling system. Once compressed, the freon is in a volatile, high-pressure state. The compressor is powered by a serpentine belt, which provides the energy needed to compress freon refrigerant to cool the car's cabin. Replacing Your Car's AC CompressorĪt Landrigan Auto Pro we recommended that car owners replace the complete AC compressor assembly because the compressor replacement core operates under extreme physical pressure. Call today at 31 and talk to one of our pro mechanics about repairing your car's AC compressor.
