Nakakasira ba to ng Aircon???

[alwayz_yummy]

i mean pala ung common econo cars,trucks,vans,etc...

[ILuvDetailing]

oo nga pala may cabin microfilter pala to... sorry na overlook ko.

[alwayz_yummy]

e di madali palang linisin yan..lesser dumi for the evaporator...

[OTEP]

Hindi ko din pinapalinis yung sakin. Sinasabay ko na lang ang cleaning during repairs.

A few things about aircon:

1. During the 70's and 80's, an airconditioner could last the lifetime of the car. Tibay talaga ng mga aircon that time but inefficient. Compressors are mostly piston types which quite heavy for the engine and evaporators are made of copper piping and aluminum fins. To make things lighter and efficient, manufacturers use vane type, wobble type, etc compressors. Better for the engine. As for evaporators, they switched to pure aluminum to make it efficient, lighter and slimmer.

2. If you want to pro-long the life of your evaporator, make sure that you always clean your interior. Vacuum at least thrice weekly specially the front passenger side. Avoid bringing in pet dogs or cats inside your car. Bumabara yung balahibo sa evaporator.

3. The ac system is a closed system so never have your system refilled with refrigerant. Freon btw is a product name for refrigerant 12 made by dupont. Most new model cars uses R134a refrigerant. If you think there is not enough refrigerant, bring your car immediately to a reputable aircon shop and have it check. Kung kulang ang refrigerant cgurado may leak yan.

4. Why not have it refilled? Like your car's engine, the compressor needs lubrication to run efficiently. The ac systems lubrication mixes with the refrigerant. Therefore, if you keep on refilling just the refrigerant, lumalabnaw ang lubrication. Sooner or later, your compressor will give in. Masmahal ang gastos.

5. The recommended interval for cleaning is between 2-3 years. Better if you can do it every year but it is costly for most people.

6. When having a general service of your aircon, replace the drier and expansion valve. You can have the old valve cleaned butit is better to have it replaced. Corrosion and micro dirt could have started to accumulate.

7. I recommend that you use the original valve for your ac. You can buy replacement valves, fittings could be the same, but most probably not the same calibration. OEM spec is that the valve should lower the temperature right after the valve at zero degree. To achieve this, the pressure of the refrigerant must be reduced to a specific pressure. If it is not calibrated properly, zero degree will not be achieved.

8. regularly hose with water your condenser, the one in front of your radiator.

9. Have the bearing of your compressor clutch checked at least once a year. If there is noise have it replaced. The the bearing stucks up, the compressor hub could be damaged.

10. This is a must to prevent costly repairs to your ac. If it stops cooling, stop using the AC. Bring it immediately to your trusted aircon mechanic.

Most AC will give you worry free operation for at least 4 years. Beyond that, it all depends on how you maintained your AC. There are exceptions though. Korean cars like MB100 and Starex have history of evaporator problems at less than one year of operation.

eto naman tanong ko....

pano kung kabubukas pa lang ng makina, tapos nagbukas ka ng aircon. pwede bang iset kagad sa no.2 ung aircon? sabi kasi nung iba nakakasira daw....

Those are myths. There is no sense to it. If every component of your ac is in good condition, walang problema even if you used no. 4 pa. In fact, you will notice that in auto aircon systems. The ac goes to full blast as soon as you turn it on to immediately cool down the cabin.

Vehicles now are equipped with vacuum switch valves (also known as idle up valves) or ecu controlled. When they sense that the aircon unit is running, the engine rpm is increased. For most cars now, you dont even have to warm up the engine before turning on your aircon. Pag-start, turn-on the aircon, then zoom zoom na.

i think sa blower lng ang fan settings, not really connected to the sealed a/c system.

eh bakit nilagay pa ng car manufacturer yang thermostat na yan kung di rin pala pwede galawin?

[niwde11]

after reading the first post, kaya siguro nasabi na nakakasira dahil iba iba ang nakakabit or design ng isang kotse. example ay ang esi body na civic(like mine) compared dun sa mga early vtec civic(96). tingnan mo mabuti yung themostat. yun esi(94) walang red bar(heater) while yung vtec has blue(a/c) and red bar(heater). siguro dahil assembled yung esi(no heater) dito while yung early vtec ay cbu sa japan(cold country). my ac mechanic ay "hindi" nya iniencourage na galawin yung thermo na may heater(very complex/arguable explanation).lagi nya pinasasagad sa coolest. pero kung purely blue bar lang yung nasa thermo, galawin daw hangang gusto. now, eto pa isang variation. yung pajero at adventure(yata) ay hindi nag-iistart yung red bar hangat di nag-zezero yung blue bar sa rotation as compared dun sa vtec(trooper din) na habang numinipis yung blue bar ay kumakapal naman yung red bar(simultaneous). kaya nung ask ko about sa pajero, sabi nya ok lang din daw galawin since di gagana yung heater habang inaadjust within the blue bar. kaya try to compare yung themostat(ac) desing ng vehicle nyo. HTH.

Eh yung mga bagong kotse may blue and red bar. So yung sinasabi ng mekaniko mo eh wag galawin ang thermostat pag may heater? tama ba? mmm... interesting.

Thanks for the detailed explanation zeagle.

which one ba? yung like sa vtec(simultaneous) or pajero(matatapos muna yung blue bago mag red)?
as what boybi posted, yung red ay para sa heater(independent sya talaga sa aircon). kung ang thermostat mo ay combination ng blue and red(like sa vtec 96), pinalalagay nya sa coldest always while kung like sa pajero(local gen 2) na di gagana yung heater hangat di napupunta yung blue(a/c) sa lowest, ok lang daw pag-papalitin ang pwesto.

Yung sa X-trail ko hiwalay yung blue (left) and red (right), so if I follow your mechanics advice, pwede ko siyang galaw galawin? Yung sa adventure (ss 2003) wala atang red marker so wala siyang heater so dapat palaging ilagay sa coldest setting?

yung red bar is hot air coming from the engine heater. ginagamit ito ng aircon pang timpla sa hangin para mabilis magbago ng temp ang output air. like kung naka max cooling ka, gusto mong bawasan ang lamig, kung walang heater, hihintayin mo pang mawala yung lamig sa evaporator para magbago ang output air. pero kung meron heater, magmimix na yung cold air from the aircon and the hot air. totally indenpendent yung heater sa aircon system mo.

[CLAVEL3699]

Ako ginagalaw ko sya... para wag masyado malakas ang aircon.

para hindi sagad compressor tama ba ako?

[wrcastro_ph]

Ako . everytime sasakay ang misis ko. ginagalaw ko. Dahil gusto nya malamig na malamig. Tama ka Clavel, para mas matagal mag ON ang compressor. pero ewan ko kung makakatulong yan para tumagal ang serbisyo ng aircon.

[CLAVEL3699]

yah. Kunwari sa gabi masyado na sya malamig ang gagawin ko bawas ako thermostat para hindi sya malamig masyado.

Honda Civic pala car ko may blue and red sya.

[boybi]

yung nakikita nyo pong red and blue markings, design lang po yun. the minute you move the slider or the knob away from the full/coldest setting, papasok na paunti-unti ang hot air.

yup, ganito nga explain ng mechanic sakin(sa trooper kasi ganun at nakipagtalo pa nga ako nung una). but since me pajero at that time sa shop at ganun yung nakita ko dati, ask ko sa kanya? sabi nya pwede raw siguro galaw-galawin yung ganung design ng thermostat(pajero).
