You get to choose the color you want and staining wood is not a difficult DIY project.

HVAC replacement turns into a full duct tear-out inside walls, floors and ceilings, including lots of sheetrock and concrete repairs.

There are two solutions that we topically recommend: (we are a license HVAC company in the DC are) one is to separate de ducts for each floor, and add automatic dampers controlled by thermostats on each floor.

Several items were not finished including a missing gutter, unfinished trim, and completely covered a bathroom vent (the duct now vents into my attic).quite a few columns of nails completely miss the joist (I was able to see this after opening up the interior)I ate the cost of two additional dumpsters because he didn't know what size he needed.I'm not going to eat any additional cost due to his shoddy business operation.

David, I did like your point about not installing AC ducts unless you are already opening the ceiling for something else. 

On the day of her lease ending and her returning the keys to me, I walked in the house saw she didn't use primer but painted white quickly on the walls and the color she used prior to painting it was showing through the white paint!

Let's assume:- a 10x12 room- ceiling one color, with a simple piece of moulding in the same color- walls a different color- 2 windows, 2 doors, cutting in- two coats needed- not including painting baseboards and casing and prepping all done.

I mean what do they need your hud 1 for its none of there darn business what color your underwear are in this deal.

The difference in the brick vs siding on your house could be made more appealing through good use of a darker color with white trim.

Adding ducts is expensive.
