central air - new question added

Ok, I'm not sure if it's in the budget since I only have a couple of K and i need to do some 0otherprojects as well, but does anyone know a ballpark figure on central air.  I have a 1200 sq ft house, with forced hot air, a fairly new furnace and duct work.  I'm thinking roughly 2700.  1500 for the unit, 1000 for the labor, and 2-3 hundo for misc parts.  Am I in the right ballpark, or am I way off on this.

If you already have the ducting for the forced hot air, you should research doing most of the work yourself.  It's not that hard especially since you have the ducting.


I installed my own central air in my house.  That included making the duct work.  The only thing I needed an HVAC guy was to pull the vacuum for the freon.

from what I understand the pipes need to be brazzed (sp?) and not welded.  I know I need to take off my skirt and be a man about certain things, but major hvac (I think this qualifies) and electrical I won't touch

AtomSmasher:
I would guess that your estimate is about right, but it doesn't cost anything to get estimates from your local contractors, so I'd recommend you start calling around to see what a few places say it will cost.

mpm32:
The pipe connections need to be sweat like copper pipes, the difference is you need to use silver solder and the appropriate liquid flux.  Really not any harder than sweating for plumbing.  When the HVAC guy comes out to pull a vacuum, you will see if you did a good job as a leak will show up at that time.

I'm sure if you look around the web there will be some guy that documented his project installing AC.  And there has to be tons of info out there and probably forums that would help.

Take a look at www.buildyourownac.com.   ;)
