central air on residential flat roof
(OP)
What are the options for constructing a central heating and cooling system in a house with a flat roof, no attic and slab on grade foundation? The home is 1400 sq ft with cinder block exterior walls and currently has an evaporative cooler on the roof and gas wall heaters. All ideas are welcome.

High-velocity system, distribution could be tucked into soffits, at least in part. Hope the penetrations don't leak too much.

At home in SoFla, it's not uncommon to see an entire system mounted on a flat roof, external ducts and all, insulated and painted. Clearly somebody sells horizontal weatherproof air handlers for that servce. I have no idea how they seal or flash the penetrations; I'm guessing lots of hot tar.

A rooftop evaporator exposed to the atmosphere atop a flat roof is probably operating in a more benign environment, efficiency-wise, than the same evaporator installed under a moderately pitched roof. ... and is easier to access for service.
