Aircon problem: doesn't cool when not revving

[Nelson Cabrega]

Hi, I have a Mitsubishi Adventure 2000 model. The aircon seems to be not blowing out cool air when the engine is idle or when I am not revving the engine. But when I am revving it up or driving in the expressway the aircon is still not that cold or 'hilaw yung lamig'. Could there be a problem with the compressor?

Could be compressor but check if your freon is low. If it's low, you have a slow leak in your AC system.

BTW, are your aircon evaporator and condensers are clean or when was the last time it was cleaned?

It was cleaned a few weeks ago and at the same time the freon was replaced. Didn't notice any change in the coolness of the aircon.

Was it running ok before you had it clean?

Nope, the aircon wasn't cool even before the cleaning.

Was the aircon cold after you had it serviced (cleaned and recharged with freon)?

I suggest to check the freon. Maybe you have a slow leak.

The freon levels are fine. There were no noticeable changes after the cleaning and refilling of the freon. I tested this by just parking in the street with the engine and aircon on but the aircon wasn't blowing the normal cool (hilaw na lamig).

Did you check the fans? Baka mahina na ikot or did A/C technician check the compressor Kung ok pa buga?

one of the best indicators of the health of your airconditioning is the manifold gauge. you can get the temperature of the refrigerant inside the system both on the low side and the high side. there is such a thing called the "pressure-temperature chart" this is very self explanatory as long as you see the pressures on the manifold gauge. there is no point in guessing. that's why the gauges were designed, you just have to know how to read them

check nyo po a.c. aux fan baka baliktad ang takbo pabuga.... dapat po ang air papunta sa engine....

pwede din pong masyado mababa thermostat nyo.... try nyo isagad.... yung manual type na thermostat dalawa po ang adjustment nun... yung mismong adjustment at meron din ginagamitan ng screw driver.... alam po ng a.c. techinician yun....

or it could be the compressor.... mahina na ang high side....

Sa tingin ko wala namang problem sa fan kasi manonotice mo talaga yung difference sa lamig pag nakahinto lang pati pag umaandar yung sasakyan, parang hangin nalang siya pag traffic tas pag umandar na ulet lumalamig ng konti.

Pero kung mababa lang yung thermostat bakit pag tumatakbo malamig ng konti pero pag nakahinto talagang parang hangin lang.

kung okey ang charge ng freon and bagong linis din, malamang mahina na compression ng compressor, kung 2000 model pa yan sulit ka na diyan ang price ng compressor Mit-Air pang adventure 10K orig na yon, filter drier linis ng system balik sa dating lamig yan..

kung mga surplus ba okay lang din?

depende sa makukuha mo, pero personally, kung pwede naman i repair pa yung compressor mo pa-repair mo na lang.
nabiktima na ako nyan before (nung medyo engots pa ako sa oto). bumili lang ako ng surplus compressor para dun sa singkit ko... 4k lang ata.... after six months, bumigay din.

ended up changing to a brand new sanden compressor... hanggang nabenta ko yung sasakyan, malamig pa din yung AC.

kung ganun high pressure po.... cause nyan barado na or madumi na ang condenser.... possible nagbabara na mga tubo hindi na makadaloy mabuti ang freon sa condenser... and or yung mga fins ng condenser mo eh barado na po at hindi na makadaloy mabuti ang hanging ng aux fan nyo...

pag barado na or madumi yung condenser pano gagawin dun?

[CVT]

I agree. Compressor problem na iyan, bro.

pag barado na or madumi yung condenser pano gagawin dun?

case to case basis... ginagamitan ng chemicals para mawala ang bara.... then flush with water then oven heat ang condenser to remove moisture pag may kahit kunting moisture sa loob ng condeser mag cause yan ng bara sa system (moisture will freeze).... then pressure test to test for leaks up to 450psi pag condenser....

kung may mga maliliit na leaks palitan mo na condenser mo ng bago at hindi na tatagal yun.... (take note pag hangin lang ang gagamitin para matuyo ang loob ng condenser sigurado may moisture pa din yun) (pag refrigirant naman depende sa klase ng refrigirant) yung refrigirant na ginamit ang maiiwan sa loob ng condenser and pag nilagyan na ng 134A pwedeng magkaron ng chemical changes sa refrigirant mo (134A) at mag cause ito ng high pressure... malamig kung sa malamig pa din pero pag matagal ka naka idling at medyo mainit ang panahon unti unti ulit mag high pressure ulit ang system mo.

kung external lang ng condenser ang barado, pressure water washer lang to remove dirt sa mga fins....
