No use of aircon at high speeds, why?

[Gerbo]

When i bought a new compressor last year the old lady in the shop specifically told me to disengage the aircon during speeds of more than 100 kph to prolong compressor life. Does this make sense?

Anyway, when I used the car 2 weeks ago at medyo nagmamadali, I average 100-110 kph and 2 hours later before I arrived at my folk's home. Nawala lamig ng aircon.
Naisip ko tuloy sinabi ng ale? What gives or is it just a thermostat problem?

[cablespy]

sounds like bs. have compresser replaced.

[cocoy]

what most likey happend was that your compressor was producing too much pressure that may have iced up your evaporator..the termostat would have shut down your compressure.
but if after you drove normally again and the aircon compressor didnt cycle on again then that could be a totally different problem...

Doesn't make sense....

It looks like nag-overpressure sa linya kaya nag-shutdown ang compressor. How is it nowadays?

AC compressors can stand high engine RPMs

your problem could be somewhe from leak to electrical or mechanical fault

you'd be rather it checked by a qualified tech

[Gerbo]

A ok.

What's the cause of compressor overpressure?

[XTO]

I do follow that saying at more than 100 kph…. wala lang

Because personally I consider my a/c compressor as important as my engine so sending it side by side to it’s LIMITS will not give any takings in the future so I suppose it could really lessen the existence when subjected to continuous high revs.

[yapoy86]

aircon compressor is designed to withstand high RPM specifically... some advise it should be turned off so as to lessen the stress on the engine at high speeds or at inclined roads..

since it is attached to the engine, manufacturers surely incorporated it in the design that it can take high rpms.

[L3GO]

SIR;

kailangan pong i switch off ang a/c switch kung hi-speed or mag overtake para gumaan sa makina, skabilang banda maari pong bumigay ang bearing ng compressor and mag burn out ang magnetic clutch.......

pwede rin pong nag hi pressure ang a/c system at i cut ng pressure switch ang current supply ng compressor, mas mainam po n ipacheck nyo po sa a/c technician bago p lumala ang sira....

[[archie]]

same recommendation yung nasira yung compressor ng crv ng dad ko. yun naman parang nag crumple yung compressor kaya palit. sabi wag daw aircon sa high speeds kasi hindi kaya ng compressor... ano po logic dito? kasi ba mas mabilis ikot ng pulley at high speeds?

pero yung sa ek ko kahit takbo ko 140kph-180kph hindi naman ganon.

[den1106]

This is only a myth about not turning on the air conditioner at highway speeds. Kung totoo kasi ito hindi ka na puwedeng magbukas ng a/c sa highway. And we know that isn't true. Otherwise, lahat ng makita natin sa highway pinagpapawisan na dahil walang a/c. The timing was pure coincidence lang. Marahil talagang may problema na ang compressor beforehand. They are right, the compressor was designed and engineered to handle those high RPMs.

I will advice to bring your car to competent a/c repair shop.

[flakez]

ako pag hahataw, as in yung tipong laro-laro mode pinapatay ko aircon. pero pag cruising even at high-speed naka bukas aircon ko. hehehe.

[afrasay]

Di kaya reconditioned ang nabili niya na compressor? Pag di ka sany tumingin di mo mapapansin yun recon sa brand new.

[mbeige]

Ewan ko kung saan niyo nakukuha yan, sa owner's manual ng sasakyan ko it is recommended to use the A/C mostly during high speed drives to take advantage of the added cooling effect on the condenser.

As what others have said, find a different mechanic or take it to a reputable shop. Have the A/C electrical sensors and switches checked, it's possible something was not done right. At high speed your A/C should be cooler because your compressor is spinning faster and thereby giving more cooled air.

I have no problems on mine even all the way up to 160kph. It's also the original on my car, and my car was made in 1983.

[youngrider]

'Computerized' car models have automatic controls to disengage the compressor in excessively high or low A/c system pressure. The compressor is also automatically disengaged during 'wide open throttle' or when the car really needs power e.g. when accelerating heavily, going uphill, etc.

[shadow]

another car myth by the neighborhood mechanics....kasama na sa design ang A/C compressor during high speed...

[alwayz_yummy]

pure bs.. i drive my maxima high speed no aircon issue..lumalamig pa nga lalo,e..

may prob ac system mo. your pressure switches are at wotk!

+1 on that Pat... :D

[Gerbo]

Ok...the car is parked at my dad's farm house....anyway, I happened to use it 3 days ago for a long drive. The sliding thermostat was adjusted to the fullest end and after a 1 1/2 hour high-speed drive di na lumamig aircon and when I felt the evaporator its icy cold.

On the way back, I adjusted the thermostat level to halfway and after another 1 1/2 hour drive, the aircon still works fine (i.e. malamig pa rin).

[XTO]

It’s just a matter of preference, you can switch the compressor off or on and yes, it can and it’s designed to withstand at high speeds/ RPMs no issues about that but the question is how long it could last? dun magkakatalo yan, say how many years before the compressor will give up or needs to be overhaul / replaced.

Also the climate of the place it’s being used. humid countries like ours where a/c is always a need at any time of the day kaya mas maikli life span ng compressors dito. not to mention pati battery dito sa 'tin mabilis bumigay sa init ng panahon….it’s a major factor IMO.
