Hello BITOG, I have a quick question for you. The Jetta in my sig often sits directly in the sun so it gets pretty toasty, I notice after starting the car that the A/C takes a while to start blowing cold air. Typically it takes 30 seconds or so before you feel cold air coming from the vents, before that its hot/warm air. My Accord on the other hand starts blowing cold air almost immediately. I know the Jetta has one of those variable compressors, does that have something to do with it?

Should have bought another Honda. That long without cool AC is not tolerable in the south. I would have to install a remote start if it didn't have one to pre cool the cabin.

I use windshield shades for all my vehicles. Made by covershield. Helps a lot with tint. My truck takes a while too but it gets there. I don't know about modern German cars, but the old ones struggled in Texas, even when new.

From what I've read, VW's seem to have pretty lackluster A/C.

I'm pretty sure the compressor in my Malibu is a variable Compressor. Takes about 20-30 seconds to get cool air to come out. My car also sits in the direct sunlight all day at work. Once it starts blowing it usally drops between 40-45F coming out the vents with the ac set on eco.

30 seconds???? Remember, all the vents/ductwork are all super hot too. Use a windshield sunscreen, crack windows a tad. Open all windows fully when starting out to get all the hot air out that you can. Use recirculate to get heat out of interior pieces. Have you changed the cabin air filter??? Have the freon level checked? Cheers2

There are too many variables here to give you a good answer.

The color of the paint, the type of glass, the fan mechanism -- these all factor into whether or not the AC works as well.

For example: If the Honda has a stronger blower motor, larger ducting, and electric cooling fans that run at max speed then it'll do a better job at evacuating heat from inside the cabin.

30 seconds and you are complaining?

I suspect that the car is still under warranty?
You may want to bring it to the stealership and let them check it, if you are not satisfied.

OMG. You might know by know I was a mechanic at a Honda dealer before moving on to becoming a UPS semi mechanic.
People bought a new 6th gen Civic new when I was there and we got complaints for the lousy AC it had. The condenser on those old Civics are
barley any bigger than a paper towel.

The best AC in a late model vehicle I've experienced was in a Buick Regal. I'd put it up against anything.

I think for any given class of vehicle, the American car in the bunch will have the best AC. We're rather spoiled here in the US when it comes to air conditioning and we like it ice cold ASAP. lol.

Thanks for the responses guys, it's most noticeable whenever the car sits out in the direct sun. We always use a sunshade to keep it as cool as possible and keep the interior in good shape. I just thought it was odd since my Honda also sits in the sun daily yet as soon as I start it up cool air starts coming out almost immediately. It may just have to do with the variable compressor on the VW.
