Does climate preconditioning work for you? I tried it for a few months and gave up. I always go to and leave work at pretty much the same time but air con never came on ahead of time. Every day when I leave, i see a puddle of condensation in the car though. Then one day at 5pm instead of 7pm, i went to pick up something from my car and notice that the air con turned on. Since then I turned off the preconditioning as its prediction was not working.
