Guys need your advise on my AC Unit

**eyescube** · February 7th, 2004 03:38 PM

Mga bosing,

Whats seems to be the problem on my REVO GLX Yr. 2000 AC Unit, last Oct. 2002 nagpa-refill na kami ng freon then again lately napansin ni misis na di na gaanong nalamig yung AC, i think its very odd na 2 years palang eh nagpa-refill na agad ng freon, di ba it takes years bago ito ma-deplete kasi nga nagsi-circulate lang yung freon...Paano ba ma-determine kung merong leak ang AC? tsaka whats best thing to do then? sa CASA ko ba dalhin para ipa-check or home service na lamang ng isang AC Tech. para i-trace kung meron leak? kayo ba ilang years bago kayo nagpaparefill ng freon?
need your advise please.

thanks

Hindi dapat nade-deplete ang refrigerant. Closed system iyan parang aircon sa bahay. Yung Montero namin is still on original refrigerant, 1997 model pa yun.

I usually have my a/c stuff done at Mang Mario in Bago Bantay. Nakapunta na sina Ungas, GlennSter, mbt at CaRGirL dun.

Kadalasan, butas na evaporator ang problem. On a Revo, it requires taking down the dash.

Doc Otep, kung sa ganito bang problema,kaya nila ba sa Mang Mario lalo nat aalisin yung DASH ng REVO kamo? kasi iniisip ko rin baka kung ipabaklas ko eh baka merong masira or di pa nila na-encounter ang mag-tanggal nito, tsaka magkano naman aabutin sa ganitong problema? or magkano naman pag evaporator problema?

calling for bosing Ungas,Cargirl,MBT,Glennster, need your advise please, na-encounter po nyo itong naging problem ko? magkano po inaabot expenses nyo?

Try lowering the thermostat or temp control to 50%, baka po nagyeyelo lang ang linya. I suppose your wife did notice the cold temp dropped after a long drive with thermostat up 100%.

Pag butas ang evaporator, minsan may lumabas na mabahong amoy. The freon stinks inside the cabin. Pero kung pinhole lang ang singaw walang amoy. I think it costs 4-5K each evaporator. Merong ibang klaseng evaporator na sealed type like Pajero's use which will last double or sometimes triple the lifespan but the price starts from 12K up.

Freon refill, airduct cleaning & other services is plus plus. Other shops require dryer also changed after 2-3 freon refills.

You can tell pag kulang and freon by looking at the glass peepehole on top of receiver dryer dapat buo ang ikot ng freon hindi bumubulabula.

Ingat ka sa mga a/c shop. Madaming shop pag lapitan mo at sabihin mainit ang a/c they will recommend paltan ito paltan yoon. Always ask for 2nd or third opinions.

Tama si Oep, freon can last for even 10 years pag walang singaw.
First check kung sumingaw na freon by looking at the receiver dryer sight glass para at least may clue ka kung ano ang problema

Pag dual aircon po kailangan 2 blower bukas (front and rear), there are some instances that the dryer unit window showing bubbles even after filling it up full.

eyes,

Yes, kaya nila Mang Mario ibaba iyan. Sila nagbaba ng dashboard ng MB100 namin (evap problems, too) as well as a BMW 3-series they were working on (same problem). Madami talagang sasakyan na kailangan pang ibaba ang dash to gain access to the evap unit like some Pregios and the REVO.

I just use an ordianary evaporator. Mga Php4K nga ata ito if I recall correctly. Ang labor at freon ni Mang Mario ang Php 1,200 total.

Tiwala na ko kina Mang Mario. He does not recommend changing parts. Hanggat makukuha sa repair they will repair it. Pero yung evaporator, kapag butas, palit na ang recommendation niya for that.

Madami ngang gagong a/c shops. Evap lang ang problem pati drier, expansion valves, at kung ano ano gustong palitan. Ultimo tape at basahan na gagamitin sinisingil pa sakin. Hayuf!

hmm, thanks for the tip guys... at least malinaw na sa akin ang possible problem ng AC unit ng REVO namin, laking taka ko nga ng malaman kong very odd daw yung nagpapa-refill ng Freon na 2 years pa lamang...

Doc Otep,

paano nga pala yung location o map ng kina Mang Mario... paki post naman po dito detailed direction... tsaka by appointment ba? meron ba tel. number?

One more thing Doc Otep, kina Mang Mario nagawa rin ba sila ng mga minor trouble shoot ng sound set-up? kasi merong problema yung sounds ng REVO namin, nawawala yung tunog ng speakers sa driver side at sa likod din eh since na may possibility na bubuksan yung Dash baka pwede ko na rin ipa-check up yung Audio ko, ano kaya problem nun? loose connections ba?

thanks again.

pag leaking ang evaporator mo kadalasan mainit talaga sa loob ng sasakyan..check mo na rin ang condenser mo..at just incase na pagawa mo sya..pwede mo na rin palagyan ng heat insulator yung firewall ng engine mo from the inside
