Installing a split air/furnace system yourself.

[dmn]

I have done lots of research about installing a split air/furnace system. Being sort of a handyman, I found that it is pretty easy to do it myself. But never done it before, I just wonder if I am underestimating the task. Have you ever done it before?

   Are you replacing an existing system or starting from scratch?   When I built my house, about 8 years ago,  I set, connected and started up my own equipment (trane TWE041E and TTF036 14.5 seer Florida Comfort System).  It consumes very little Force.   I had the good people on the other side of the building design and install the duct work for me  If your static pressure isn't right, the unit will never function correctly, no matter how well you pipe it and connect it electrically.

I've decided to hire a contractor to put a system in for me due to not being able to buy the brand I want. Thanks for the input anyways.
