di yan masisira provided na you maintain your a/c system. i have my a/c cleaned once a year, i asked the mechanic once, for the compressor daw may sinusunod sila na high and low pressure, on the high side wag lang daw sosobra ng 200psi and 20-30psi sa low side. nakakasira daw ng compressor is if you exceed 200psi on the high side, causes daw para magexceed is dirty lines and too much freon charging. oo nga pala, it disengages daw before reaching 200 provided the system is working properly so no need to worry
