    Kasi pag maiinit bumababa at tapos babalik sa tamang IDLE niya..

    Sabi baka daw my barado ung evaporator kasi lagpas daw ung sa 300 ung PSI at gumagalaw ung pangsukat nila habang tinetest, tapos isasabay na rin palitan ung drier at expansion valve, eh bago pa lang naman yun expansion at drier...

    Salamat po sir..

    Sir, condenser po yung nasa tabi ng radiator. Pero di ko talaga ma gets kung bakit kelangan ibaba yan dahil sa tingin ko pag barado ang internals ng condenser ay lower yung high side pressure reading dahil yung high side service port is located after the condenser (just after the drier) in TXV (expansion valve) system.

    Maaring barado lang yung condenser or evaporator fins mo o mahina yung mga fans mo. It could be also due to presence of air in the A/C system or overcharged talaga.

    Yung drier usually palit talaga after a major repair, yung expansion valve naman pwede wag na basta di lang mapasukan ng dumi while your a/c is being repaired, sabi mo bago pa naman.

    Sori po sir, un ga daw po ung ibaba, kasi masyado po siya maiinit lagpas 300, Kasi last december nagpagawa ako ng compressor, pinalitan po ng mga bearing, nun naayos po un maganda po ung lamig ng aircon pati po takbo ng sasakyan.

    Pero napansin ko lang ung idle niya bumaba, last Feb..

    Ewan ko nga po kung nu tlga cra nun... wala na ako masabi bout sa sasakyan eh.. sori po..

    Sir 'bambino' ano kaya ang magandang gawin sa a/c ni 'mykelan212002'.

    Kung kotse ko yan sa tingin ko papa-check ko uli yung pressure readings, kung 300 PSI talaga sa high side medyo mataas nga yan for a sedan, I am looking for 27 to 35 low side pressure and 180 to 235 sa high side depende sa ambient temp.

    At 300 PSI, I'll evacuate my A/C system, vacuum for at least 30 minutes and recharge it by weight as recommended in the manual, pwede na kaya yung O.6 kg sa ESI.

    Di kaya baliktad yung ikot ng mga fans, dapat parehong pahigop, power wash narin yun yung radiator at condenser, merong kotse na pwedeng i-power wash yung evaporator with out removing it.

    Maaari ding may problema sa idle-up system ng kotse, pero yung 300 PSI sa tingin ko eh kelangan talagang i-correct.

    YOUNGRIDER TAMA YUNG PROCEDURE MO MERON LANG AKO IDADAGDAG.



    ang masasabi ko dyan ,recover muna yun refrigerant para masukat ,honda civic yata yung kotse di ba ?

    1.35 lbs lang ang dapat karga nyan , pero kung sobra ang init ng panahon

    - 10% pwede na to protect the compressor .

    then evac put the right amount of oil and recharge ( 1.20 lbs.)

    during testing (performance test)

    low side = 30 - 45 psi

    high side = 175 -225 psi

    considering the ambient temp at around 35 C

    IF ANY ABNORMALITIES FROM GAUGE READINGS , AND IT'S NOT COOLING ENOUGH , AND IT'S TIME TO DIAGNOSE IT.

    AT LEAST THE AMOUNT OF REFRIGERANT IS RIGHT THIS TIME.

    malamang overcharged nga yan ,mabuti pa pasyal ka na lang sa malapit na A/C shop at pabawasan ang karga .

    mahirap ata humanap dyan ng fully equipped shop kaya puro overcharged yung nababasa ko dito .

    basta tandaan mo * idle

    low side 30-45 psi

    high side 175-225 psi

    at 2500 rpm hindi ka dapat lumampas sa 250 psi.( R134A)

    itaon mo na tanghali para mainit .

    70 PSI sa low side, ang taas nga. Goodluck po, sana maayos kaagad ang A/C ng kotse nyo. Second the motion po ako kay sir 'bambino'.

    Tama ka jan bro. Skilled at competent and techs nila jan sa shop ni Mang Mar. Mabilis at reasonable ang price. Sila ang nagpatino sa AC ng 1988 Nissan Maxima ko. Mahihiya ka ngang hindi magbigay ng malaking tip sa technician kasi talagang aalis kang satisfied.

    Yun nga lang, may isa akong request... sana mag-diet na si mang Mar. High risk na ang weight nya. Ayaw kong magsara ang shop nya. LOL!

    Sa mga hindi pa nakakaalam ng shop na ito, mga Tsikot bros, try it!!!

    plano kong ibenta sasakyan ko. mahinang mahina na aircon. malaki ba ang maidadagdag sa value nito kung ipayos ko ang aircon? o sayang lang ang gagastusin?

    If you are planning to sell your car and worry about the additional expense on your part, just have the aircon estimate for repairs, then have the next owner aware of what needs to be done. It might add up to anything between 5k to 8k in additional selling price (so I think break even).

    Reasonable price ba yung promo ng toyota ngayun? Example for an INNOVA DIESEL, it cost Php 11,794 (parts, labor, materials + VAT).

    Pag kay Mang Mario ako magpapagawa, magkano aabutin kung ang papagawa eh katulad ng offer ng toyota?

    i've been going to mang mario since 2005 pa. ganun ako ka loyal kasi mabait naman sya at mga tauhan nya. and minsan free na yung ibang parts. and free charging narin pag misyado marami nag papagawa. para next time nalang daw ako pumunta at agahan.
    pero this is what i realized... halos every year minsan 6 months lang nga or minsan after a month ako nag pupunta dahil nawawala yung lamig. pag alis mo sa kanila malamig pero after a day or so nawawala nanaman. pero di agad ako nakakabalik kasi busy rin ako.
    naka 2 palit na ako ng cooling coil sa kanila.
    1 surplus compressor..( fr mitair converted to denso. nag snap yung belt ko yung pala dahil hindi na fit para sa denso yung belt. di ba nila alam na iba ang belt na dapat gamitin? sa auto supply ko pa nalaman.)at 3 pressure switch na laging nag leleak.
    ngayon mainit nanaman a/c ko. i think it's time to say goodbye to mang mario. i'll have to find other shops na mapapatino aircon ko.

    i had our old crv gen1 fixed there before. AC was ok pero not so cold.
    just lately pinagawa ko civic 96 ng misis ko. ang sira lang was fan was replaced. pinasabay ko narin linis ng aircon since hindi pa nalilinis ever. (low milleage lang kasi un civic. we got it 2nd hand with only 33000 kms). oh boy, after wards the air con was so cold even on tanghaling tapat! and at nights, the windows would moist up because of the cold. problem ko lang ngayon.. nasira ata nila un switch. ayaw gumana sa fan setting number 1. nag sta start sa 2 na.

    dieselNUBI,
    Sounds like a thermistor (hope I got the term right) problem. The switch really wears down after a few years, especially the number 1 setting kasi parating nadadaanan. It can be fixed but better to have it fixed sa electronics shop (e.g. sa gumagawa ng TV) because most modern cars use a printed board type circuit to control the fan switch. Baka nagasgas lang sobra.

    Share ko lang very bad experience ko.
    Nasira yung clutch ng compressor ko after dumaan sa baha. Brought my car to mang mar, they replaced the clutch with a new one. after a day biglang nagstall yung car ko buti nalang malapit lang sa house. yung car ayaw talaga magstart parang stuck up yung engine. upon further inspection yung clutch & pulley pala ng aircon ang stuck up. after removing the aircon fan belt ayun one click na. binalik ko ulit sunog daw yung clutch and he told me na I will shoulder the cost of the new clutch WTF. Sabi ko bakit ganun kakagawa lang niyan sira agad. mang mar looking really pissed agreed to replace it. Ako naman matagal na din nagpapaayos sa kanila & pakisama na din decided to pay half nung cost ng new clutch. So ok na ulit, after a week nawala yung lamig. so check ulit i need a new compressor na daw kasi lost tread daw yung fitting ng compressor ko sumisingaw doon. WTF! wala pang one year yung compressor ko bought it bnew sila din nagkabit. naalala ko yung tao niya todo higpit nang todo higpit mukhang dun nadale. ginawan ni norman ng remedyo napalamig ulit. after a week nawala ulit yung lamig. check ulit sabi ni norman kailangan ibaba yung dashboard para macheck daw mabuti I agreed & left my car. Mrs. called me na butas daw yung evaporator ++ other parts. So gave her my go signal na ayusin na which cost an arm and a leg. wow! ang lamig kahit tanghaling tapat kayang kaya. after a month humina na naman yung lamig. takot na ako bumalik sa kanila mas makakatipid pa ko kung magtayo ako ng sariling shop para lang ayusin aircon ko.

    ang pag ayos ng CAR AC nowadays ay kailangan na ng precision testers and equipment para no guessing .

    lalo na ngayon ang karamihan gamit na ay R134A REFRIGERANT .

    sa mga old systems na R12 pa ang gamit pag kinargahan ng R134A sibak agad ang compressor dahil mas mataas ang head pressure ,at karamihan overcharged pa ( dahil kulang sa gamit yung shop ).

    sa leak testing naman kailangan ng electronic leak detector para hindi na ibaba ang suspected part .

    pag na ibaba na yan kahit walang leak palitan na . yun ang idea ng karamihan .

    to run a leak test with proper equipment ,it only take max of 20 minutes , and no guessing .
