Air Conditioning at Idle

[toastyfries]

Hi,

I live in Arizona, and it gets pretty hot. When at stop lights the AC isn't nearly as cold as when driving. It's still cool, but not chilly cold. If I rev the engine to about 2k RPM in nuetral it gets chilly.

Is this normal? I'm thinking it is normal, but now that I've found a forum with all these helpful people I figure it can't hurt to ask. I'm talking about when it's above 100 outside. During the winter, spring and fall I don't notice it, since it's not as hot.

I've had the freon checked by one of those "free a/c check" places and they say it's full.

Thanks

Yes thats normal. When you hit the gas a little your speeding up the AC which allows it to cool better. I notice this more on my car which has a 135,000 miles. Not sure the miles on your winnie but my winne has 80,000 and it does it on hot days as well. If it were newer it may not be as noticable.Now if it were to get warm it may be time for a freon boost.

I live in the hot southeast and my ac struggles on hot days while in traffic. Once on the road, the van cools down just fine. But while in town, I've learned to switch the rear unit with the vents directed forward. I've done the maintenance checks on the ac system and everything checks OK. However, I have not yet cleaned the inside fan wheel or the ac coil.

As soon as I get an extra moment, I intend to short-circuit the coolant hoses going to the front heating coil .... why have that heat in the cabin during the summer? I think this will help, especially when making a lot of stops during travelling, as the heat coil dissipates a lot of heat inside the cabin during a rest stop.
