What is it

When the client booked the inspection, he had never seen this type of heating system. Said the heating unit was outdoor with the a/c unit. Right away, i think heat pump. This is not a heat pump (i think), what is it? How does it work? Anyone have some info I can pass on to the client?

thanks in advance

Not seen anything like that. So...I assume that ductwork is split into supply and return air. Filter(s) at the interior return grills or is that the reason for the odd "tent" shape? Is that enough exposed ductwork to be concerned about insulation or is it double-walled?

One last question and I promise to shut up...Does that lower section also contain the emergency heat strips?

Hi Richard,

Think combo gas furnace and AC unit mounted on the roof of a commercial building and it's essentially the same thing. I've done about a dozen of those on various commercial buildings and in one case on the roof of a high end condo. They're not much different than an ordinary gas furnace only they're placed outside and they don't require a chimney.

ONE TEAM - ONE FIGHT!!!

Correct.

Correct again about the typical filter location, but I have no idea what that tent shape is.

Around here it would just be insulated inside. I'm sure that may vary in other regions.

I've not seen a two-tiered unit before, but normally there would be no emergency heat strips in a gas unit.
