Having it in the kitchen tile or as wrap on duct work is a lot better than having it in the drywall. 

I know that sometimes a condenser gets stolen from the the outside but this has no AC at all and will now need the duct work as well as the AC system which could cost me 10-15K.

I just had a difficult layout house where multiple heat pumps would be needed and we decided to do a wall mount, LP furnace and run flex duct work to each room.

The house has a forced-air system, so the ductwork is installed.

A remodel 3-2 chk a/c ,heat, plumbing ,electric,walls ,drywall, ceiling popcorn knockdown ,$$$ windows,doors, garage door,interior & exterior paint ,molding, fascia ,roof, landscaping, pool, pool-heater, sprinkler system, well,septic or city,appliances, trash, demolition, duct work, termites, floor, MTG & ins, ...what will you do what will you hire out .

What would be a good estimate for the cost of putting in duct work in a house that does not have central air, cost in sq footage preferably.

I have a 700 sq ft property that has never had any duct work put in or any A/C unit other than a window unit.

During rehab we had to pull sub floors out to replace duct work and that's when the real fun started.

Best thing to do in rehabbing a mobile it not to use standard mobile fixtures,toilets, tubs, sinks, hot water heater, duct work and if you can doors, windows should be off the conventional housing shelf, not the RV or mobile home shop.

Some between 10k-20k in my opinion b/c these have been sitting empty for years and thieves have stripped them of any & all components they can re-sell.Ex) Furnace, duct work, copper plumbing, re-shingling roof, floors repaired & refinished, possibly new electrical if the inspectors are watching you closely (which they WILL BE from the website's verbage), mold and/or asbestos remediation, etc., etc.Then throw in the cosmetics.
