turn off the a/c when start?

Do you turn off the air conditionner before start the engine? Or you can let it on everytime?

 

you can leave it on, but i always recommend turning it off. leaving it on puts unnecessary stress on the motor and all when you crank the truck up.

 

I've always left mine on. By stress do you mean on the starter?? I'd agree w/that. lol Never really gave it any thought.

 

well, whether it creates too much of a load, which i have always believed be it the case or not, i always turn mine off. and i got the wifey doing that now too!!

 

I always turn it all of before turning off my truck.

Mildew?? That changes it.lol AC off.Living in the desert I'd forgot about that stuff.

 

Tring to sneak in first time poster?? Welcome to TW.

 

+1- Habits from work- the A/C just always was on the list to be off before the ignition. Plus I'll roll windows down pretty often.

SgtJim- Welcome to the board!!

 

I try to turn the AC off a minute or two before I turn the truck off, Usually when I turn into the subdivision I will turn it off and let the cold air out of the ducts so mildew does not form or at least help it not to form.

 

I voted yes but honestly mine is rarely on & when I need to defrost have found the first setting (defrost & feet) works the best for me. Never thought about the stress on the engine.

 

+1, Think I used my A/C only two or three times so far this year...

 

I can't really agree that the A/C will put stress on the engine when starting. With 236 HP I don't believe that would be an issue. As far as hurting anything, I had my last vehicle 10 years (98 Chevy Conversion Van) and never turned the A/C off and never had a problem.

 

Im 50/50 on this if its hot outside i live it on so when i get ready to leave work i can hit my remote starter and cool it off but at night i will turn it off when i turn into the neighborhood just because

Idk why i do just seems like the right thing to do just trying to save the enviroment by saving that .00000001 gallon of gas LOL

 

Triangle dude:

Regarding the mildew smell. There should be a drain for your condensor in the firewall on the motor side. make sure it isn't clogged with something. The water should be able to drain freely and you shouldnt be getting the mildew smell.

I went through this on my beater VW a while ago, the hole was clogged with shit, after I unclogged it the smell went away. Stick a coat hanger or something in there.

 

I have mildew problems and have read plenty about it on other boards. In the hot/humid climate here, many cars (my taco included) smell like dirty diapers if you run the a-c and let them cook a couple of days.

The manufacturers generally recommend that you run the system with compressor off a few minutes before shut-down, to dry the evaporator coil. There is no way to flash this into control system, as the ECU has no idea when you are going to shut-down.

The air conditioning condenser engages after the engine starts. It does not load the starter.

 

I go one step further as well and turn it off when I'm about a half mile from home. Gives the condensation time to drip off so I don't have a puddle on my garage floor. I've heard that helps the compressor as well if it's frozen with ice.
