Anyone know about residential HVAC?

The installation is more important than brand. It needs done right or any brand will fail. Ask friends, coworkers, neighbors who they use and trust.

I sell mainly Armtrong(Lennox product) Rudd and American Standard, but I can get most anything. If you were closer I'd give you quote.

Most that I sell is 14 seer which was high efficiency not long ago. Bump above that you get into more components to fail and more out of pocket. It pays off eventually if you maintain it. Upper seer units require a TXV that's guaranteed to fail eventually.

Help me out. What's a TXV? American Standard is what we did on our upstairs unit a few years back, worked out great.

What DocJJ said. It meters the flow of refrigerant into the evaporator.

This, many times over. Also, make sure they do a "Manual J" to get the size right; oversize is almost as bad as undersize. If they won't do one--or especially if they don't know what it is--they're highly suspect. They shouldn't charge to do it, either.

That was what they replaced on our Trane system, at the time my buddy said that most systems were having issues as they used the same source for them.

i work for 2 brothers that do HVAC and plumbing,they keep busy so they dont want to go back and fix anything, since its on their dime,they looked at call backs vs brands and Lennox(Airflow) had the fewest so thats all they will put in.
