Took delivery of my P90DL last week here in AK. I have to say that unless I'm missing something, I'm pretty disappointed in the HVAC performance of this thing so far in cold temps. First off, it really sucks the power more than I was anticipating. But that's not a concrete complaint. Specifically, when driving in 0-10F temps, which are pretty common around here, the HVAC cannot keep up with defrosting all the windows, much less keeping floor warm. The windshield can stay fairly clear, if you have the floor heat off, however with even just two people in the car (much less 7), all the side windows frost up like crazy! There should be a lot more CFM and BTUs available. This of course also makes my consumption about 500Wh/mile, so I really only have about 170 miles of usable range. Thoughts? Did I get a lemon of an HVAC system? I've never read of anyone having trouble keeping their windows clear on here in cold climates.
