In my Tacoma with the v6 and my 09 scion xb I couldnt tell a diff with ac on or not. In my geo and insight it feels like such a load.

To make your home ac more efficient they have variable compressors. Of course most home ac runs at a constant speed and with enough extra capacity it cycles off and on. With a car its speed varies a hell of a lot and cycles as needed. Many newer cars use an ecu vs high and low psi sensors to cycle the compressor off and on. Plus it works the ac differently if you have the eco mode on or sport. My insight the ac is always colder with eco off and sport mode on addition to the settings. Eco off makes it 1 step colder, sport makes it another.
