I'd imagined that in this relatively modest-sized house the HVAC guys would recommend some dedicated make-up air system, with dampers and duct heaters and all that mess. But they just presented a plan that just upsized the size of the furnace fan (not sure to what) and upsizing the AC compressor from 2.5T to 3.5T. It's not a high-efficiency furnace, so there is an duct run that brings fresh air in.
Does this sound reasonable to you?
No!
Increasing furnace size to accomodate make up air? Yikes!First check with your local building codes on make up air, they may have some requirements you have to go buy. Without the lay-out of your kitchen it may be a bit hard to get a concrete sollution. Maybe call a mechanical engineer in your area for ideas. Is their an architect involved?
How about a vent in the kitchen with a reversed damper to open on negative pressure and close on positive pressure?
