Need more info on

what specifically is suggested. In the biz "direct fired" usually means a system where air, usually outside air is pushed right over the gas flames without benefit of a heat exchanger like the one in a furnace. These are used in gialnt paint shops or welding shops or auto repair shops were alot of warmed makeup air is needed. Modern apt. retrofits should be done by gas heat, elect is easy to meter but very not cost effective for the tenant. I like to see at least a "MagicPac" by Armstrong/Lennox if you want the AC in one package or there are alot of direct vent wall furnaces some up to 90% eff. The really nice way to go is a wall hung boiler.
