Unbelievably Parasitic A/C

Anybody else have issues with the A/C sucking down fuel economy? I spend the majority of my time on the road without the air on, because I can watch the Econ estimator drop .1 mpg at a time. Disgusting. Any ideas for curbing this? It's always hot in South Florida, even when it's cold.

Anything that takes power from the engine drives down mpg, wether it be wipers, lights or A/C. You have to accept the lower mpg if you want cool comfort just don't set it to so cold maybe, you're not trying to stop icecream from melting.

lol @ stopping ice cream from melting. I will give the a/c system credit there, it is freezing. None of vehicles have ever had this kind of parasitic a/c. My 03 Accord EX (2.4L) averages 28 mpg with the a/c running all the time.

In my winter beater (2002 Neon, 90hp lol) if you go WOT and turn on the A/C you can really tell what a difference it makes!
Of course the Cobalt automatically disengages the A/C when you go WOT. It knows you can't have both

Options to improve are to cycle the A/C on and off.
If you don't want to do that you could get an underdrive pulley.

I do most of my driving with the a/c off. When it gets REAL hot, I do exactly that^ (cycle the a/c). Im looking into an underdrive pulley for my 2003 Accord, because the lights dim constantly (and I plan on having it for a looooong time. I only have 48k miles on it at present.)

All car A/Cs are parasitic. One tip to keep things cooler switch your fresh air off and recirculate your cabin air. That way you are cooling cooler air compared to the air outside.
