Varying amounts of exposure to sunlight will modify its electrical return signal to the programmer to adjust system output toward cooler air; less sunlight will cause the programmer to adjust system output toward warmer air. Some multizone climate control systems have more than one sun load sensor.
To check the auto a/c compressor compression ratio, note on paper the low and high side gauge readings and add atmospheric pressure to both readings. Divide the high side reading (with the atmospheric pressure added) by the low side reading (with the atmospheric pressure added).The result should be between 6.5:1 and 7.5:1. A compression ratio of 8:1 or higher may cause compressor failure. Learn More…
The A/C compressor is considered the heart of the refrigeration system. Compression ratio is the technical expression for pressure difference. Compression ratios are used to compare pumping conditions for a compressor and is an efficient way to evaluate the health of an air conditioning compressor.

How to find an auto ac compressor problem, before is too late?
Check for high compression ratios. To check a/c compressor compression ratio, note on paper the low and high side gauge readings and add atmospheric pressure to both readings. Divide the high side reading (with the atmospheric pressure added) by the low side reading (with the atmospheric pressure added).The result should be between 6.5:1 and 7.5:1. A compression ratio of 8:1 or higher may cause compressor failure.
How long should an air conditioner compressor last in a car?
The air conditioner compressor should last the entire life of the vehicle. The car ac compressor damage is usually a sign that something else in the cooling system or car ac system is not operating properly and is negatively impacting the auto ac compressor operation.
Driving the car with a locked up a/c compressor may damage the accessory drive belt. A bad compressor could affect the engine in your car. If your compressor’s pulley bearing goes bad, your engine can stall due to the stuck compressor or the serpentine belt may break affecting all the accessories moved by the serpentine belt.
Types of A/C compressors and compressor lock up.
Clutch-less variable displacement compressors have extra protection in case the compressor seizes. In the event a compressor failure occurs the bridges on the clutch assembly will break and only the pulley will keep running, allowing the engine to keep running.
Do you need to get your car’s a/c compressor checked up ?
Low refrigerant charge causes rapid cycling. Drive belts and blower resistors do not affect compressor cycling. An excessive air gap may prevent the clutch from engaging.
