I know about the severe drain of the PTC heater (and its many-minutes-delay before supplying heat) so if I need to change the interior temperature or get rid of moisture, I prefer to open the windows a bit, rarely using the A/C, and in winter combine this with intermittent bursts of using the windshield defogger button, turning it off as soon as the A/C has made the windows clear again.
