Di masyadong malamig aircon pag tanghali...

kung nag-hi-high pressure, mahina na ang condenser fan ninyo. may mga aircon shops na pinapalitan lang ang pinaka-motor ang condenser fan. problema ay yung hindi original na motor. minsan iba ang amp load ng replacement. minsan naman, mahina ang buga.

subukan mo palitan ng original na motor ng condenser fan.

also, i have to say na malaki ang difference ng trusted na shop sa magaling na shop. pwedeng trustworthy nga ang shop pero kung hindi sila magaling, sasablay pa din ang aircon mo. (halimbawa kung ang mekaniko mo ay sobrang trustworthy nga, pero pihadong sasablay pa din yan gumawa ng makina ng eroplano.) eto kasi problema ko dati. sobrang trustworthy talaga ang dati kong aircon shop na pinupuntahan pero puro remedyo lang ang alam niya gawin. nang dinala ko sa isang magaling na shop, wow, sobrang lamig ngayon ng 12-year old na sasakyan ko. kahit naiwang naka-park sa ilalim ng araw sa tanghaling tapat ang kotse ko, pagpinaandar mo na, in less than 5 minutes malamig na sa loob. sulit.

twink..trusted aircon shop nmn yung pinagpagawaan ko. bale kasi ganito nangyari nagpa-convert ako ng freon from R12 to R134a ( flush out lahat ) Dati sa R12 malamig kahit no.1 lng, eh sa R134a parang kapiraso n lng ung lamig. Hindi ako nagpalit ng compressor kasi maayos pa naman diesel kiki ung compressor ko... appreciate any inputs, tnx.

Unknown to some, converting R-12 to R-134A in a system designed for R-12, will lose 5-10% of aircon capacity and causes high discharge pressure. http://www.sanden.com/support/retro.html
It will help to replace your condenser fan to a much bigger or higher RPM fan to lower down the discharge pressure and compensate for the decrease in capacity. Of course you will have to replace your expansion valve, filter drier and compressor oil to POE oil suited for R-134A.

Observation ko lang, parang mas nalalamigan ako sa R12 na freon kesa sa R134a.

Ganyan talaga ang R134a compared to R12. I had mine converted, kasi it's too costly to maintain the R12. At least for now ganun muna, so when I save up I can probably have it converted back to R12 and replace all bad lines and components (exp valve, evap, etc).

Also, dapat both refrigerants (R134a and R12) come from a metal pressurized canister, not the cheap ones na nabibili sa auto parts store (parang DIY). Yung high pressure na sinasabi ng tech mo can probably mean it's being compressed properly (hence the high pressure) where it's needed. You might want to invest on some low shade of tint to allow for better cooling pag tanghali. Other than that I think the last thing you can do is check kung tama yung amount of refrigerant na nilagay ng tech mo. I don't know what your car is or how much it needs but they should know. If it's lower than the recommended, siguradong mahina siya.

dawa>>>> txt kita kung sakali...tnx

mbeige>>> tinted na po ung sasakyan ko.. siguro ung condenser fan lng mahina.. try ko palitan... tnx

**jpatricks1** · February 7th, 2008 01:23 PM

Nangyari sakin dati baligtad yung polarity ng aux fan. Try nyo dapat pahigop sya ng hangin imbes na pabuga if youre facing the front end.

1 taon ko din tiniis to kung san san ko pinagawa yun lang pala problema. Nug binaligtad ko ayos na.

**twink** · March 4th, 2008 07:28 PM

UPDATE:
ung condenser fan lng pala may problema, hindi na sya nag-automatic switching kaya mainit ung condenser kaya mainit din ang labas ng hangin. bale nagpalit ako kanina ng fan (900) + labor at freon charging (400). ngayon malamig na aircon ko kahit tanghaling tapat...

guys advice naman. i recently replaced my cefi's compressor. i didn't pull down the evap to clean but i replaced the drier. on my orig a/c, it could reach 4 degrees using a thermometer sa vent. now 6-7degrees na lang sya.

do i need to have the evap cleaned again? or flush the a/c system? please advise.
