Hina lamig..palaki "tik-tuk" compressor

[Gerbo]

What does this mean?

Kaka-check up pala last week, no leaks s a system daw. Di rin uminit compressor binuhusan ang tubig.

Baffled with this. Please help. Car is an old 93 Corolla GLi.

[youngrider]

Ano daw ang low at high side AC pressures. Is there no problem with the compressor clutch. Baka yung compressor belt tensioner ay stucked-up.

gerbo, your "tik tuk" could be caused by one of the two: too low suction side or too high discharge side of the system. there is a compound pressure switch at the recievier dryer of your corolla. any pressure outside the threshold would trigger the "tik tuk" or short cycling

Pa-evaluate ko na rin.

Ano ipapaayos or adjust pagnag-short cycling?

gerbo,
have pressure checks done first:
a. system pressure at rest
b. system pressure at idle speed once airconditioning system is stabilized(i.e. around 15 minutes after start up)
c. system pressure at around 2000 rpm
make sure you get both high and low side pressure garuge readings

mga sir, tanong ko nalang din po yung tungkol sa oto namin about sa "tik tuk" sound na yun, Eto rin po kaya malamang ang pwedeng sira ng aircon ng oto namin, kasi laging kapag nakabukas yung ac habang naka aircon, sobrang lakas ng tik nung sasakyan, pero kapag pinatay ang ac, nawawala naman...naka mazda familia 323 big body po ako,sabi ng erpat ko parang sakit daw ng mazda 323 yun...thanks po

Mas mainam na ipacheck mo yung system pressure para madaling ma diagnose katulad ng sinabi ni jick. Free estimate naman yan sa mga AC shops at dun mo makikita kung ano ang pressure pag nakaoff and on ang ac. Di po sakit yan, katulad ng sinabi ni jick, malaking possibility na nagcucut-off and on ang pressure switch nyan.

Most probably high pressure ang problema. As jick.cejoco is suggesting, kailangan talaga i-check ang system pressure for both suction and discharge. Ang nakikita ko kasing problema sa mga gumagawa dito sa atin, karamihan ay hindi na naglalagay ng gauge sa discharge, they just look at the suction pressure, tapos konting tingin sa sight glass kung meron man, at kung sa palagay nila ay ok na, recharging is finished, kaya hindi na nila nakikita yung other side (discharge) ng system. Kaya kung may mag-crack up na problema dito na magsisimula yung palit dito palit doon. Ito yung maling pamamaraan ng pag-rerepair ng MVAC system.

As the owner, karapatan ninyong malaman kung anong klaseng repair ang ginawa sa A/C sytem ninyo.

May mga indication naman ang maayos na A/C shop.

1. Kailangan malinis ang lugar. Walang maraming kalat. Yung dumi
(contaminants) ang unang kaaway ng A/C system.

2. Technical Know How and Skill ng mga technician, it's true, maraming magaling mag-dismantle, kaya lang marami pa rin sa kanila ang kulang sa basic theory ng airconditioning.

3. Proper Equipment.

At least they have this basic but essential equipment for proper A/C servicing.

a. Manifold Gauge. (Malinis, walang crack ang mga
hose. Both high and low side are working properly. Kailangan pa nga mag-kaiba yung para sa R12 at R134a kahit gumagamit sila ng adaptor).

b. Vacuum Pump. (Maraming Car aircon shop ang wala nito, hindi ko lubos maisip kung bakit wala sila nito, kung walang vacuum pump ang pinuntahan ninyong a/c shop, hanap na lang kayo sa iba na mayroon nito, mas-malaki ang chance ninyo na magagawa ng maayos ang inyong a/c)

c. Electronic Leak Detector. Mas mabilis ito at reliable kaysa soap and bubble method. Kung kailangan itaas ang pressure ng system for leak testing kailangan dry air or Nitrogen (OFN-Oxygen Free Nitrogen) ang gamitin para maiwasan ang moisture contamination.

d. Weighing Scale. Kailangan ito para maiwasan ang undercharging 'o overcharging, mahirap magrely sa sight glass lamang.

e. Temperature Gauge (Thermometer ba ang tawag dito. Para maiwasan yung malamig na sa technician pero mainit pa rin para sa nagpapagawa, at least meron kayong basehan kung ano na talaga ang temperature.)

Hopefully makatulong sana ito para 'dun sa mga nagtatanong kung anong klaseng shop ang puwedeng mag-service ng maayos.

Good customer relations ay important din.

maraming salamat po, at least kahit pano nagkakaron ako ng idea kung san talaga problema, para once magpa check-up ako hindi ako tutungo lang basta sa sasabihin ng gumagawa..thanks po!

for the basic: kung bakit tumutunog na "tik-tuk"

Magnetic clutch are composed of 1. stator or magnetic coil (eto yung nakarewind na wire para magproduced ng magnetic field) 2. rotor or pulley 3. pressure plate.

Kapag nagkaroon ng power supply sa magnetic coil siyempre makakaroon ng magnet at didikit ang pressure plate sa pulley at lalayo uli pag wala ng power supply kaya mula noon hanggang ngayun nabuo ang alamat na tunog na "tik-tuk".

Sir Den 116, if i may ask, do you know any particular shoo with these complete equipment, even Denso is not compleye. Thanks

I assume you are from quezon city, kaya lang matagal na akong wala diyan sa metro manila kaya wala siguro akong maituturo sa iyong shop. You tried Mang Mario or Ceejay, sila yung mga kilala dito sa tsikot, baka sakali kumpleto sila.

Sad to say even famous names like Mang mario or ceejays is not complete. What most shops lack here are recovery systems,thermometer,charging machines and leak detector. Shops here always get away without these equipments. Sana they can be required by law.

If I will take your word,I'm assuming again that you've already been in their place (Mang Mario & ceejays), I have some feeling that they also belong to one of the many incompetent shops as shown on the following thread:

pero may mga times na di nila ma diagnose correctly yung problem,. akala ko kasi isang check lang alam na yung problem, hindi pala. di ko alam kung na hit and miss ako pero ginawa na yung condenser(yung parang radiator) hindi pa rin lumamig,. pinabili pa nila ako ng thermo stat kahit na ayos pa yung thermo stat ko.. tsk,. how bad,. sabi nila baka daw sira yung drier or condenser kaya inuwi ko nalang muna.. short ako sa budget eh. pero lumamig naman sya kahit papaano... kung dati 10% yung lamig, ngayon mga 30% (bagong refil kasi freon eh) overall, nagastos ko is 2,000php.. 1400 php lang sana yun kung hidni pinalitan yung thermo stat...

mga tsikoteers, wag kayong madisapoint sa sinabi ko, Ok naman sila eh, very accomodating, magaling din daw, sakin lang hindi..

hehe, wala lang, share ko lang

Ito yung resulta ng mga kulang sa proper equipment. Most of the time hit and miss ang troubleshooting. Kaya maraming nakakalusot at akala natin ay mahusay na ang isang shop, dahil ang a/c system lalo na sa mga sasakyan are very tolerable, hindi agad ito nagpaparamdam ng problema until it breaksdown.

Ito ang isa pang classic example:

HINDI NA AKO BABALIK SA KANILA. im making this long post out of frustration from their service.

we used to be a satisfied customer, we had our cars serviced there since a few years back.

pero lately, sunod-sunod na bad experience namin sa kanya.

1. less than half a year, lagi na may nasisira sa a/c ng lancer ko (*maybe* di talaga nila kasalanan, pero kung magaling sana sila, nap-prevent sana to.) lagi may tagas sa seal here and there.

2. everytime nagpapagawa ako, OVER PRESSURED lagi a/c (freon) ko, which i discover obviously after i've left the shop and kung kailan super init = BAD TRIP. (symptom is compressor disengages, but the idle rpm rises above normal. bago servo ko.)

Heto yung sinasabi ko, it seems everything is fine, but inside the system mayroon nang namumuong problema,(i.e. a lot of moisture inside the system) dito na mag-uumpisa ang mas malaking problema, kumbaga sa tao, nagkaroon na ng cancer. With the proper equipment and knowledge of how a/c works, (lalo na yung effect ng moisture sa loob ng system and they know how to remove it) tama siya, it can be prevented. And it will not shoretened the life of his a/c system.


3. despite that, i still recommended them to my bro, nasira a/c ng adventure nya. assessment sa kanya, butas daw evaporator, pero di in-explain nang maayos. hindi car-junkie bro ko, so to be sure, he asked for 2nd and 3rd opinions from other shops. WALANG BUTAS daw.

4. went back to mang mario's to have them check the evaporator again (since rekomenda ko nga sila), pero NABASTOS lang daw siya ng worker at ni mang mario himself, saying something like eh di pagawa nya raw sa iba. nice "customer service" eh.
(for those who frequent him, im sure you'll agree na may pagka-arogante talaga si mang mario at mga tao nya).
of course, my brother just left the shop immediately, pissed.

5. my lancer's a/c broke down again a few weeks back. (less than half a year since it was last serviced by them). took it to them, assessment was BUTAS EVAPORATOR. i just realized they leak-tested it WITHOUT CLEANING THE EVAPORATOR. basic ito ng car a/c diba, papaano ka magde-detect ng leak kung marumi yun. moreover, mas lilitaw nga yung butas pag natanggal yung dumi.
--i was quoted P5,800 for service + orig evaporator. wow mura, but too good to be true. i asked orig and replacement parts dealers, mahina na ang 6k. too good to be true.
--since di na ako convinced sa trabaho nila, took my car to another aircon service shop, ni-refer sa amin ng co-league ng bro ko.
--immediately, the worker spoted that there was OIL on the expansion valve, dead-giveaway of a leak in the area. (WTF, di nakita nila mang mario yun?)
--to be sure, he leak-tested it again. cleaned the evaporator, observed it underwater, all the while in-explain pa sakin yung symptoms pag may leak. verdict, WALANG BUTAS.
--pinalitan lang yung seals, replaced it. then the usual vacuum and recharging. ayun, malamig na ulit. excellent craftsmanship. total bill was a little over P1k.

btw, the a/c shop i'll be going to from now on is AVES AIRCONDITIONING. to give you an idea of their prices, their basic cleaning service is P1500 daw. sure, di hamak mas mahal kina mang mario, pero VERY PROFESSIONAL service in my opinion. WORTH IT. mala-warehouse yung place, can fit more than 10 cars (pero napupuno sila). mababait lahat ng tao, from service crew, to secretary, to the owner himself (mr. rex).

also, i noticed they used IMPORTED FREON (from japan yung nakita ko ginamit sa akin), naka box pa at naka-small shellane-like tanks. (unlike mang mario's small beat-up tanks. malay ko ba saan galing yun.)


LESSON: kung GIPIT kayo, sure you can try and risk it at mang mario's. cheap place.
if you want to be sure of the quality, go somewhere else, ask your friends.

Ang totoo nito, itong mga ganitong problema ay maiiwasan if they have the proper equipment at kahit konting theory lang sa basic ng airconditioning. Ito lang naman ang dapat gawin ng mga incompetent shop.

Acquired proper equipment and

they need to go back to school, learning is a lifetime process

This post is not to discredit them, kaya lang bigyan naman ninyo yung mga customer (car owners) ng tamang serbisyo. Mag-invest sana kayo sa mga maayos na equipment.

At para naman sa inyong mga staff at technician ganito ang para sa kanila:

that's the reason why we need to reeducate them and require them to get at least a local training and certifications. why sell incompetence to the paying public?

[bambino]

i strongly agree with den1106, kailangan talaga ng mga techs ang proper training.

Ano na kali nangyari sa tsikot ni Gerbo.

[Gerbo]

Ano na kali nangyari sa tsikot ni Gerbo.

Naayos na po sir.

Twice ako bumalik sa isang aircon shop. After a week nawala lamig. So I finally went to another shop hoping to get another diagnosis.

Result? "Camshaft seal"(?) leak sa compressor. Same defect as my other Corolla before.

So far. So good pa. 3 weeks na.

Salamat.
