AC compressor + high rpm = damage?

[recklus]

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

guys if this is true bakit yung sa gen2 crv ko dati nagpalit ako ng compressor 2 times in 4 years? yung 1st time sa casa then yung 2nd sa ibang shop sa banawe? all of them said na dahil daw due to excessive rpm? I find that hardly true kasi bihira naman ako mag hiway and hanggang 4k rpm pinakamataas na na reach ko. all of the compressors na pinalitan ko is orig pa (keihin ata tatak).sa bwisit ko binenta ko na yung sasakyan dahil Ive never experienced it on my other cars

^ baka naman lemon?

minalas ka lang siguro at puro mahina na compressor napalitan sayo, gen1 crv ko with 105k on the clock orig compressor pa rin, granted di na tulad sa lamig ng bnew but still cold enough.

agreed. same din to nga corolla ko 10 yrs orig ac comp and hindi talaga same ang lamig dati noong bago pa xya.. meron difference.. pero ok pa nman ang lamig.

Yung Benz ko 24 years old na siya, I *think* original Harrison compressor pa rin yung nakakabit. Lamig lamig ng AC rin. Well it can only go 5250rpm hehehe. Diesel kasi.

I always turn it off, just in case. The only problem would be that you're stressing the compressor clutch (automatically disengages at high rpms to prevent damage), but if he does it every single time, it's probably the same thing.

And, yes, it does make a difference. The guys at Speedlab showed us a B16A Civic on a roller dyno, being held at half-throttle... turning on the blower and compressor together cut maybe 15 hp from the engine's power. Yes, the SiR has a small engine. The only time the compressor will make a negligible difference in performance is on a big block or a 300hp + turbocharged engine... for us small N/A guys, it's like driving through molasses.

nung nasira compressor ko for the second time i took it to banawe and sabi nga nila na sakit na ng gen2 crv yun. talagang madaling masira,must be the compressor brand ata. I tried to find a fabricated replacement pero wala. Yung orig parin pinakabit ko and guess what? nasira after nung warranty. both times hindi overcharged ang freon dahil dun sa hi and low nasa tama naman (or at least yun ang pinakita sa akin), yung sa banawe malabong naloko ako kasi dun talaga ako nagpapagawa madalas. yung sa casa hindi ko sure. Kaya nga bago pa masira yung ika 3rd na compressor binenta ko na.

They might have been overcharging your car with freon. This causes very high pressure under high RPM.

Of course, they blame high RPM when you bring it back to them, pero culprit talaga is freon overcharging.
