A/C proper usage

[Kasenklaud]

mga master,

tanong lang kung anong proper na pagbukas ng a/c naka fan ba muna at off ang thermostat o sabay na bukas ang fan at thermostat...? anong mas mabuti para humaba ang buhay ng a/c...?

[shadow]

Doesn't matter really...either way walang problema but I don't see the logic of turning on the fan first bago buksan yun compressor..makes no sense

Parang aircon sa bahay? Fan muna bago Low Cool? I don't want to add unnecessary wear and tear to my switches. Basta I make sure that the AC is off before I start the engine to minimize load on the starter and battery. I turn off the aircon first before turning off the engine.

+10 bro..yung iba naman kase pag ON ng switch sagad agad sa high para daw lumamig agad..

Summer is officially here! Honda Cars Philippines, Inc. imparts practical tips on proper use and maintenance of car air-conditioning unit to beat the summer heat. The air-conditioning unit is an indispensable item in today's car especially in a tropical country such as ours.

In new cars, problems hardly ever occur but after a length of time, depending on the working conditions, its efficiency naturally diminishes. So, it is advisable that car owners know how to properly use and maintain the car's air-con system in order to obtain the longest possible service.

Here are the following suggestions:

1. Check the position of the compressor control switch (A/C knob) if it is in the 'open' or 'shut off' position. One should shut if off before starting the engine. This will avoid unnecessary drag caused by the compressor while cranking the engine.

2. Once the engine runs on, switch the fan on first. Blow the air-con's fan at the highest speed for about a minute in order to clear away the hot air trapped in the air-con's ducts. Then, depress the A/C knob to turn the compressor on at coolest temperature. The next step is to adjust the fan speed and temperature control switch to the level most comfortable to you.

3. Switch off the compressor before cutting off the engine. Keep the fan on at highest speed so that it blows away all humidity trapped inside the evaporator or 'air-box.' This will help eliminate the smell of stale air when you subsequently turn on air-con again, and at the same time, to lengthen the service of the evaporator. The process only takes about 2-3 minutes.

The smell of stale air inside air-con ducts can be eliminated by simply parking your car in a sunny, open space. Open all doors and leave the car for about 2-3 hours or until the smell finally disappears. Make sure that the sun's ray reaches the greater part of the cabin. If the stale smell still persists, however, consult a reliable service center nearby.

you're probably not old enough to know... but my parents insist that that you should turn your fan on for 5 minutes, before turning on the cool.. heh heh.
i didn't understand why then, and i still don't understand why now.
old wives' tales..

kahit anong style pwede. basta ang uunahin mo palagi bago pumasok ng kotse e yung....




maligo! ang kalimitan sanhi ng pagbabara ng evaporator e libag na galing sa iyo. yan ang kinabubuhay ng germs at fungi na siyang bumabara sa evaporator fins.

[gllenium]

By the way ang practice ko e: 1. turn on engine 2.turn on fan only 5. after 3-5 mins turn on A/C. My ride is Honda EK 99 5 years sa akin wala akong pinagawang sira ng A/C ko maliban s maintenance, wear & tear parts.

It does make sense imo

The starting current of a motor is really high so thats high current running thru your windings.. Parang hinahawakan mo yung fan blades habang naka on.. Then if you turn your a/c's fan & comp at the same time.. Imagine the power voltage drop in your system if it was in your car.. Which may shorten the life of your alternator/battery or any other electrical component on your system..

[JohnM]

Some cars with climate control do not engage the compressor agad when the car is started. Maghihintay sya ng ilang seconds bago kakagat ang compressor. Not sure with manual ACs though.

the starting current is high but it tapers off quickly also the compressor is mechanically driven by the fan belts.
kung critical ang pag-on and off ng aircon dapat nilagyan na ng special instruction yan sa manual.

[chris_d]

I would say it does not matter unless otherwise indicated in your car manual. If unsure best would be to turn on the engine first, then aircon fan, then a/c compressor on a manual a/c system. You can do all that in under 5 seconds anyway.

[kinyo]

owner's manual usually suggest the AC should be OFF before starting the car and before turning off the engine ... this ensures lighter electrical load during starting

as to whether the fan or compressor goes first, it doesn't matter ... most owners don't touch the thermostat setting when turning the AC on, so the fan and compressor kicks in simultaneously and does not hurt anything

pag mainit singaw sa loob ng oto (lalo na nabilad ng matagal), todo sa fan muna
habang naka-awang mga bintana.

turning A/C off - thermostat first, then let the fan on for a minute or two.

[vinj]

I keep the A/C switch "on" (and thermostat in my usual setting) and just turn on the A/C a few moments after i start the car (kung malamig naman panahon, i wait for the car to warm a bit and turn on the A/c when my idle is more settled) and turn off before shutting off the engine. Wala naman sira because of that aside from the usual wear and tear.

Ganito rin ang gawa ko. May nakapagsabi sakin na mag fan muna lalo na kapaga nakabilad
sa araw ang sasakyan. Laminated na kasi ang mga evaporator ngayon kaya madaling mabutas.
Sabi sakin, mag fan muna ng kahit 3 minutes para ilabas nya yung mainit na hangin.
Pag di na ganun kainit, tsaka pa lang buksan and engine at mag AC.
Kapag dumaloy kasi ang freon ng hindi pa napasingaw yung init, mag kakaroon ng "sudden change" ng temp
dun sa evaporator. Di naman sya agad na mabubutas pero pag ganun lagi ang gawa o practice, dun sya
mag uumpisang magka problema.

Makakatulong din na sa covered parking ilagay ang sasakyan kung pwede para kung may mainipin kang kasabay,
hindi mo kinakailangan mag fan ng mas matagal. Nung 2006 pa ko huling nagpalit ng Keihin evqaporator kaya
masasabi ko na epektibo yung sinabi sakin.

PInaka problema ko ngayon any yung Sanden Compressor ko para sa 2001 Civic LXI (dimensions body).
Every 3 years, kailangan kong magpalit dahil na woworn out yung shaft. Pansin ko na nagwiwigle yung
pulley kaya hindi nag eengage yung magnetic plate. 2005 nung una kong magpalit tapos 2008 at pinakahuli
ay 2011. Six months bago ko magpalit ng compressor, nag papalit na ko ng timing belt at tensioner bearing kaya
damay na rin steering belt at AC/alternator belt. Tinitingnan ko lang kung makakatulong pero walang epekto.

Mag 2014 na next month, sa May sched ng timing belt at sa November pa satingin ko bibigay yung compressor.
Ask ko lang sana kung meron pang ibang brand ng compressor para sa model ng sasakyan ko dahil hindi durable
and Sanden. Nakakpanghinayang na magpalit ng compressor worth 12K dahil lang sa worn out na shaft.

Thanks

[ghosthunter]

I just turn on the aircon as soon as the engine has started. Nothing more complicated than that.

No car freshener for me. This is my evaporator after using air spencer for 2 years.
