[QUOTE=Quantumstate;14746271]. Ten years before that I got a Carrier condenser with a rent-house I bought; it was around 30 years old at the time and ran great until I sold the house. Just certain brands last longer and run better over the long-haul, and you notice that if you're paying attention.
If you have been paying attention...NOBODY makes stuff like they did 30 years ago. IMO I don't shop at walmart to buy something for 1/2 the price and it lasts 1/2 as long.
jtrammel; you are going to have to understand that you guys do not have the best credibility or greatest reputation. Fifteen years ago my mother's furnace quit. Instead of calling me she panicked and called out some HVAC company, who promptly put in the cheapest crap furnace in existence, and charged her $$$$!! That is all they did -- replace the frickin' furnace. I was so angry at that company, and I have never forgotten/forgiven what they did. Don't tell me some of you haven't taken advantage of an oldster. So when you say Goodman or Lennox or Bryant is "just as good" and that it all comes down to the install, forgive me if I vomit.
Sorry your mother got taken by a box salesman, but dont group all of us into we were the ones that bent her over! Quite frankly thats insulting. YOU WERE GIVEN THE BEST ADVICE OF ALL-GET a FREAKIN SMART CONTRACTOR! And another thing this site is mainly made up of HVAC contractors that love what they do and are on here giving advice to prevent what happened to your mother..
BL due to the destruction water did to the old Payne I just don't trust sloping it back. Even with these new stainless secondaries, I'd just as soon keep waste out of the furnace. Any kind of tee you put by the furnace would let products of combustion into the room, since it's under positive pressure.
IT DOESN'T let the products of combustion into the ROOM. What BL described is also the method to use when you put a 90 plus into a crawlspace and don't have the room to slope the PVC properly.
