    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?

    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

    Guys, a friend told me that he was surprise na mag- 4 years na yung REVO ko eh di pa nakakatikim ng linis yung AC ko.

    Ano po ba ang dapat na schedule ng cleaning ng AC? How much do they charge for cleaning lang?

    Duke > Heat insulator is a good idea, pero tanong ko lang, di ba itong mga sasakyan na model 2000 above or any kind fully packed na sila ng heat insulator right?

    Sir eyescube, iisip ako ng detailed directions. hehehehe. Mahirap kasi magpaliwanag by words. Hindi ko na din makita ang number. hehehehe. Basta sa likod lang ng SM City North EDSA yun. Sa Fort Santiago St. Alam ng mga tricycle drivers sa area yan.

    Wala namang prescribed cleaning maintenance ang a/c. I just wait for it to break down saka ko na pinabubuksan. Maari pang pagmulan ng problema iyang cleaning dahil baka mabutas nila evaporator o may magawang hindi tama. May thread na about this dati. Sa Pilipinas lang naman nililinis ang a/c. Have you heard about regular a/c cleaning in Australia or the U.S.? Mas matindi pa ang conditions dun sa ibang areas nila compared sa Pinas. Sobrang mahal ang a/c cleaning sa kanila. Usually ginagawa lang kung may masamang amoy or sobrang nabarahan na ang evaporator.

    Php 650.00 ang cleaning ng single aircon kina Mang Mario. Mas mahal ng konti ang dual a/c.

    Bosing Ungas,
    wala naman mabahong amoy na lumalabas sa cabin, malamang baka pinhole lang ang leak nga kaya...

    Salamat Doc Otep sa ff-up reply.

    Calling Mam Cargirl baka meron po sa iyo tel. # ni Mang Mario?

    Mga Bosing Follow-up Symptoms:

    Sirs,
    This is what My wife observed when:

    Temperature Control was Set in LOW then thermostat was put on High then a "Krek-Krek-Krek sounds appeared parang sa Dash or sa may engine bay nagmumula pero naman pag nakalagay yung thermostat sa kagitnaan eh nawawala ulit yung sounds, Ano po kaya ang problema nitong AC ko?Why is that?what causes the sound?

    Temperature control and thermostat are the same.

    Tatlo lang ang control ng a/c ng REVO:
    *Fan speed
    *Thermostat/Temperature control
    *Vent selector

    Alin po ba ang ginalaw bossing?

    Doc ito po yon,
    Yun po AC selector> FAN-LOW-MEDIUM-HIGH (naka set po sya sa LOW)>
    Then nakafull yung ina-adjust na Thermo regulator yata yun.

    eyescube,

    kung year 2000 GLX ... ang alam ko eh meron defect ang aircon ng mga model na yan.. (denso po yata).. meron kasi ako kilala na mga revo GLX owners na less than a year eh busted na po agad aircon nila.. pero swerte kayo at ngayon pa lang kayo nagka-problem sa aircon ninyo..

    huwag po ninyo i-full ang thermostat ng revo... mga 3/4 eh oks na po dapat ... based on experience sa 2000 GL revo (sanden type) ng dad ko eh nawawala po ang lamig pag naka todo thermostat dahil nagye-yelo na at less na yung air na lumalabas sa aircon vent kahit naka todo na ang fan.. this usually happen on highway driving.. kaya laging 3/4 lang at oks pa naman ang aircon hanggang ngayon...

    once pa lang nalinis ang aircon ng 2000 revo GL sa toyota balintawak north.. mga 5K din pa-linis...

    sa case po ninyo eh mukhang kelangan na talaga ipa-check... mukhang oks po suggestion nila na kay mang mario kayo punta..

    wala din ako alam na aircon shop na mapapagkatiwalaan... at lalong hindi ako naniniwala sa mga "free aircon estimate" dahil pag binaklas na nila eh biglang dumadami ang problema..

    canvass po ninyo yung mga possible parts na pwedeng palitan para at least alam ninyo yung maximum amount..

    Dude RevoGSX,
    thanks for the input, Yung AC po sa REVO GLX 2000 is Sanden.
    Well, sa ngayon maintain ni Esmi na nasa kalagitnaan yung thermostat maayos pa na naman daw yung lamig though still gusto ko na itong ipa-check kasi nga very odd na nagpa-refill na kaagad ng Freon eh 2 years pa lamang ng na-acquire based on the history.
    i will try Mang Mario's HVAC expertise subok na subok daw sya sa quality ng work nya :

    Mang Mario in Bago Bantay call 920-1708

    Yung iniisip ko lang kung bakit merong "kreking sounds"?

Guys need your advise on my AC Unit
