Is it ok to leave the aircon on and turn off the engine?

[tidus1203]

I see some people do this. They leave the aircon on, and then turn off the engine. So when they turn on the engine again when they use the car later on the aircon automatically goes on as the engine is turned on. Masama ata yun diba? My practice kasi is always to turn off the aircon before turning off the engine....

[alwayz_yummy]

turning off the engine 1st sisirain nun compressor mo in due time, kasi biglang hihinto... tsaka additional load agad yun sa batterya...

[Arvin Cristi]

sir, my aircon technician said never to do it that way, kasi masisira daw yung clutch and compressor when you trun on the engine dahil biglang may load yung compressor, mapwepwersa daw yung compressor. hindi naman daw ganun kahirap mag on ng AC after starting the engine

[alwayz_yummy]

unang bibigay nga pala is compressor bearing--un ang uugong kung lagi mong ginagawa to

[Memphis Raines]

No. It is NOT ok to do this

Cardinal rule before shutting the engine off: Turn-Off Everything (radio, aircon, DVD, etc)

You can't be that lazy

My grandfather is like that. Nung sinabi ng erpats ko na patayin daw muna AC nagalit pa. Kaya pag start ng engine pagdating pa lang sa "ON" sa susian, umaandar na yung AC tapos pag start magpo-pause yun pag redondo ng oto tapos start uli. Naaawa ako sa Camry nya. Pero sabi nga ni 'lo, "yaan mo matibay ang Toyota.."

Tsk tsk baluktot at pinapanindigan talaga... hahaha

Aren't newer cars with computers able to control/manage the start-up of the compressor until after the engine is switched ON and in idling speed? I don't practice this. I always turn OFF the aircon before I switch OFF the engine. But I'm just curious if new cars have this safety feature already.

big ...

Yes, boybi ... some new cars have electronic control for the A/C and will disable the compressor when engine is not running.

However, every manufacturer recommends that A/C should be turned off when not in use.

Other than being an additional electrical load for the battery while the engine is not running, and as additional mechanical load when the car is started, I really don't see why this practice could possibly cause any damage to the car. Sure, the car may have difficulty starting (which justifies manufacturer's advice), but there is nothing that would tend to break. You may have consumed more electrical energy and the starter operated with higher current to start the car, but both battery and starter are so durable, the additional load is peanuts.

I guess the recommendation was meant to avoid ... peanuts?

The lolo is correct. Matibay ang oto niya kagaya ng oto natin.

guilty ako dito kasi dati sa open parking ako nagpapark, so nagpainstall ako ng autostart remote, kaya bago ako lumabas iiwan ko naka on yung aircon para pagbalik ko autostart ko at pagpasok ko medyo di na mainit, unfortunately ayun bumigay yung compressor di ko alam kung isa sa mga factor tong ginawa ko pero di ko na ulit ginagawa yung dati

[recklus]

may bad result man o wala its better to be on the safe side di ba? mahal din compressor eh hehe

[CVT]

I make sure that I turn-off everything(A/C, lights, stereo etc).... before I turn-off the engine... Does not hurt.....

[ans_lim168]

of course it's a big.....NO....like what the other tsikoteers said it will be an additional load to the battery and the compressor will definitely give...love your car and it will serve you a lot better and longer

[mazingerZ]

uubusin ng aircon ang battery charge IMHO. . . .

[mazingerZ]

Ganyan na ba katamad ang mga tao ngayon na maski pagpatay na lang ng aircon after turning off the car di na kayang gawin. Masisira ang compressor mo and will put a strain on the car's battery and alternator upon starting. . .

[wewoy_romero]

off muna lahat bago ko patayin ang engine. actually, pagpasok pa lang ng village, patay na ang aircon at blower at nakabukas na lang ang bintana. patay na rin ang radyo. headlights na lang talaga. tapos pagpark, patay muna ang headlights, pahinga ng around 30 seconds, then turn off the engine.

[Bogeyman]

I usually turn off the A/C first (thermostat then blower), apart from the lights and radio before the engine.

Minsan pag nagmamadali ako, nauuna ko pang mapatay yung makina bago yung A/C. But the next time I start the engine, I make sure that everything is turned off first.

[XTO]

Not okay for me…it will only take few seconds or even a second to turn you’re a/c on after starting, you can also allow your oil indicator to at least fade before turning your accessories on
Turning off all the accessories including the a/c thermostat will allow your/my battery to cope up and recharge – for his next “duty”.

That’s why my battery is still in good shape after more than 6 yrs I dunno?

[Black Revo]

Madalas mangyari din sa revo ko yan dati, dual kasi, esp pag baba ng pasahero mo. Kaya I make sure in-off ko AC sa likod......

According to the link above in pointer #1 yes we should not do it. So to those who still turn on their engine with the aircon already on you are just cutting short the life expectancy of your aircon
