Max Versus Normal A/C

[Notifier]

I would think you would always want some fresh air coming into the vehicle. Most household systems aren't designed this way, mainly because of cost. You can get an "air to air" heat exchanger installed on your furnace which would bring in outside air while exhausting stale air, but then these cost money! Almost all large commercial buildings with the roof top units have a fresh air intake for bringing in outside air to the building through the duct work.

When you come to DCS you will change your mind MAX during the summer.

MAX defiantly cools much more than NORM. I will run MAX most of the summer in daylight. But when driving at night you don't really need the cabin temp to be at 50 degrees.

Keep in mind, running on recirculate(max) all the time may lead to a very unpleasant mildew odor in the evap. Constantly recirculating the air could also lead to mold growing in the evaporator. My Volvo will only allow the recirculate option to engage for 15 min, then is switches back to outside air(unless you re-engage it).

As a habit, I only run recirculate when I want the extra cooling.
