How to install High eff gas in/ex vent

[David A. Andersen]

Sometimes there is only one "exhaust", combustion air comes from inside.

Not if it is a concentric vent. It has a pipe inside a pipe. One intake, one exhaust.

I was planning on doing most of the install if not all myself.

I wouldn't. The pro's can't get it right half of the time!

Im also thinking about using Goodman units that I found at
good prices online from a few diffent places.

That figures! That is the biggest piece of ***** engineered.
It will go well with a do-it-yourself install.

Unless your unemployed, and your time is not worth anything, I would not try a new install. It's worth the $$$ to learn to get it done right. I hope you don't expect a warranty (Goodman dosent have a warranty worth anything anyway, so forget that). If you were replacing something with the same parts, maybe.

Do you have centeral AC to install as well?
Do you plan to get certified by the EPA as well?

I now see others have covered other serious points, so I'll quit here.
Just don't do it! You'll be glad you didn't.

Someone mentioned evacuation. In this part of Ohio, it is illegal to work with refrigerants in any manner unles the workman is trained and licensed by the EPA to do so.

This not only applies to residential A/C, but to automotive, as well.

The fines a quite steep. Some dealers won't sell A/C units to the general public for that reason.

I realize that times are difficult for you, but trying to save a buck today will cost many more bucks tomorrow.

I been reading reviews online and hear some say goodman is junk.
then there are others that say they have cleaned up there act.
and are just as good as any since they have less complicated
electronic circuitry to breakdown.

has anyone witnessed problems with newer Goodman equipment? or
are people basing their opinions on old furnaces that have died after
10 or 20 years?

all opinions are appreciated thanx.
