Anyone Install a Humidifier on a Downflow Furnace ?
I would like to install a 95 + furnace in a my m/h and thought about using a coil cabinet rather than the non combustible base. The coil cab install could be used in a future install of a coil when my newer goodman package air goes south. Any comments, thoughts, suggestions. GBY

You most certainly could install the coil cabinet & I would suggest doing so. Just be sure to install a damper in the base of the cabinet which will open when the heat is on & be closed when using the package A/C. Many times I've found a piece of rigid foam insulation needed to be cut to fit & installed in the bottom of the coil cabinet, even with the damper, to keep the cold A/C air from blowing up thru the furnace. Sometimes you even have to weight it down with a couple of bricks. Install in the cooling season & remove when it's time for heat.

Thanks Grady. Only thing is there are some cool nights after a good storm and the heat might come on early morning. With the the Miller has I believe a 14 x 14 supply and damper is up the shaft a bit. My concern would be the static pressure with that size damper. I figure if the Trane is mobile home approved it would be able to accommodate the m/h duct system. I guess it would be better with the damper at the bottom of the coil cabinet.

The Miller dampers are directly under the furnace. The only damper elsewhere might be where the package A/C connects. My suggestion, & I know it costs more, is to install split system A/C when you do the new furnace. The next question would be if the Trane can handle enough A/C for your place.

If I had extra to spend I would go with the AC change but I have a pkg unit that was recently installed by the person we bought the place from. With the damper could it be installed in the bottom of the coil cabinet where it enters the 14x14 transition duct to the 14x4 plenum?

The Trane may or may not be able to flow enough air with the small ducts in a mobile home. I honestly don't know at what kind of static they are rated.
I understand your reluctance to install a piece of foam in the coil cabinet but the manufactured dampers just don't do a very good job of stopping the cold air from blowing up through the furnace. that cold air caused considerable condensation & can rust out a furnace in a very few years. This particularly true if the supply from the package A/C is fairly close to the furnace.
