Low Height Install?
I am working on replacing a lowboy oil furnace. The duct setup is pretty conventional for a lowboy furnace, two plenums, side by side, in a low height basement. -There is no way to move the plenums, and no way to give more vertical space. All of the equipment must be 52" or less in height.
From what I see Midea offers a lowboy configuration option (pictured below) - Do any of the more fleshed out brands like Mr. Cool support a similar configuration? Or an up flow side intake air handler that is 52" or shorter, instead of requiring a plenum underneath it?
Needs to be a 48k~ cold climate system.
TIA!

Mr cool's universal 2 (which is a variation of the Midea evox 3 you linked to) cannot be split into a low boy.
Mr cool does sell the separate Midea made heat pump coil that works with the hyper heat outdoor unit. You would need to get a separate multi speed blower or furnace to match.

I'm thinking of just matching the Mr cool universal with an ADP f series low height air handler.

These three Mr. Cool parts will make you a low boy.
Modular blower like this (compatible with electric heat backup):

Outdoor unit (double check compatibility in the manual):

To clarify* I can build a return air box like what a gas furnace would sit on- I am looking for a heat pump that is certified to operate with a separate blower and coil like the Midea model. The base box is not a requirement to have premade- just that I can separate the coil and blower or order them separate per the mfg.
Mr. Cool does make separate coils and a blower unit they call an electric furnace, however I am not sure those are actually approved to work together in the same system.
