    Brian,
    A ductless minisplit air conditioner cannot be used to bring fresh air into your building.

    If you want to introduce fresh air, you need a ventilation system. Here is a link to an article that explains your options for a ventilation system: Designing a Good Ventilation System.

    Thanks Martin because my local Mitsubshi dealer told me they have a new ductless air conditioning unit with a fresh air vent system. Tough to know who to trust in today's world!!!!!!!!

    Brian,
    Well, it's possible that Mitsubishi has introduced new equipment with that feature. But it's the first time I've heard of it.
