    I don't think the furnace being on the right side of the room would have made any difference.

    I bought a new home last fall...
    LONG ranch with a 3 room suite upstairs (guess it is not really a ranch).

    The main floor had a 4 ton unit, with HORRIBLE metal duct from the 1970's that leaked like a sieve... air did not really get to the far ends of the long main level.
    I decided to separate the main level into 2x systems: one for the living space and one for the bedrooms...
    Both are 70K 97% MOD furnaces with 2 ton 20 SEER inverter AC and the obligatory factory thermostat.
    The upstairs has lots of attic space, some of which is gonna be closed in, in the future... so I put a similar system up there with a 3 ton inverter unit.
    All 3 have new ductwork (kept the boots), with some added return capacity.

    My gas bill went down about 1/3 month to month...
    However I did not live here last summer so I do not have anything to compare the elec to.

    I can say this...
    The comfort level of MOD/Inverter is a new level... that cannot be achieved with conventional equipment.

    Oh yeah... got most of the equipment on 'personal use'... including all aluminum evap coils...

    Speaking of my system, the contactor on my 67 carrier just took a dump.
    Be lucky to get 5 years out of a new one.

    I'm just glad to hear he is finally getting with the program. I had a VS system in my office 20+ years ago.

    In Ga I bet the 70k furnaces have NEVER been out of low fire. I live in a 2 ton house but got a deal on a 75k mod furnace, old stock, rated 94% back when 95 first got ya tax credits and they couldn't sell it. never gets out of low unless it's been in set back mode. Most of the time,since i'm a single guy I keep it about 64 degrees. 9 years and have only changed filters and UV light bulbs and checked drains.
