I love my hot air conditioning...

I'm not too crazy about how badly the air conditioning works when you first start the car on a hot afternoon.. It's been a long, LONG time since I've had a car blow hot air at me when initially starting up.. Probably not since my 80's and 90's F-Bodies.. Or is it just my car?

When I first get in and turn it on it blows out very hot air for up to 20 seconds or so before it starts cooling down. In recent years, all the other "luxury" cars I've owned either have cold air blowing at me right off the bat (Lexus LS430, Lexus RX350) or they didn't blow out anything until it could give me cool air.

Pretty sure mine blows nothing for 3-4 seconds then I get cold air right away.

My air starts out hot, too, but I don't expect it to come out cold. I've only driven jalopies in the past, and they always blew out hot air initially. So I can't speak for other entry level luxary cars.

Generally, I've been impressed with the car's cooling ability - even in extremely hot temperatures (100 degrees plus).

Mines is the same but 20 seconds is a bit much, more like half.

You might need an AC service. I read that in the past BMW recommeded the AC service every two years and now it is every four years.

For about 10 sec, yes, hot air, then it cools down gradually. It takes a while to cool down the vents, air passages, etc.

My '98 Nissan has never had any a/c service and it freezes me out even when it's humid and over 95 F. I do get the impression that the 335 takes much longer to get the car cooled down. But it does work. Sometimes I wonder if the rear vents take away from the fan's ability to blow out the front.

My A/C does the same thing. It'll sometimes take a good 30 seconds before the air starts to cool off after a startup. Once it gets going, it's ice cold.

The heat soak from the engine makes it worse. There is so much heat in the engine compartment due to the turbos that it transfers over to the A/C system. This means you get warm air blowing at you for a few seconds if you are restarting and the engine is hot.
