Coleman AC
Contractors tell people they cant put ac on a small pipe system...they are telling a lie just to sell new ductwork, the Coleman system moved just as much air as a new large duct unit does, it just moved the air much faster under higher pressure, AC works great on them.Coleman did offer AC on their units in the 50s and 60s,Dunham Bush made a unit called a space pack which used even smaller ducts and simple round vents in the ceiling, they are about 2 inches in diameter, this system is still being made but under another name.
