Do you turn off the aircon when turning off the engine?

[swordsman]

I guess the aircon deserves a separate thread, so here goes...

Do you turn off the aircon first when switching off the engine? Because when you don't, the next time you switch on the engine, the aircon turns on automatically. I don't know if it has bad effects. Personaly i do turn off the aircon before switching off the engine. A couple of times though, i may have forgot to kill the aircon... buti na lang walang masamang effect pa. Curious lang ako what bad effects this causes when done regularly.

I personally turn it off before turning off engine. Yun turo sa ken before when I was just learning to drive. They say hirap engine if you don't. Sa B12 ko ngaun, namamatay engine minsan if I forget. Sa N16 ko, okay lang.. kaso I still try to heed the advice to turn it off first. Let's wait if the gurus can provide explanation...

Pinapatay ko aircon(with fan on) pag malapit(2 to 3 minutes) na ko sa bahay or san man ako pupunta.

me too.. pinapatay ko aircon then engine, or ON engine then 2-3 minutes tska on ang aircon

[sarceangel]

I always make sure that the aircon was turned off before engine start and engine stop...

Sir question...

why do you need to wait 2-3 minutes before turning the AC ON after the engine is ON? pag malamig ba engine kaya ginagawa ito? or same din kahit mainit na engine?

ako kasi pag turn ON ng engine ah susunod ko na din ang AC... is there a bad effect on this?

on topic:

i do turn the AC OFF before turning the engine OFF as well... turo lang din sa akin ng mga nag turo sa akin mag drive...

Agree here. I do this, too, especially in the morning ..... A matter of habit. Although, kung talagang mainit, I have no choice but to turn on the AC after a few seconds.

Also, turning-off the compressor a couple of minutes, leaving the fan on, just before reaching your destination, IMO, is a good practice, as the engine and battery will have a reprieve before shutdown..... Although, I do this only for one of our vehicles....

same here. 5 mins warming of the engine where it is park and i just turn on the AC after makalabas ako ng village thats about 5 mins from house to the subd. gate all in all 10 mins before i turn the dial to #1, but how long is the interval before you turn the blower to no. 2, 3, 4?
my routine po kc, i switch it to the other for approx. 5-6 mins interval, just like aircon sa bahay.
