wow . i wish i had of seen this thread at the beginning, i have been in the hvac business all my life , and my dad before me . in 30 yrs , i think i have worked on just about every brand of residential furnace and a/c that is out there .. somebuddy mentioned TRANE. very good advice, yes they are more expensive, . yes get the D.C.variable speed motor. a dc motor running 24/7 . is like 50 bucks a year for hydro, if you will be staying in the house for more than 5 yrs it will pay for itself , i have replaced more motors than i can remember , d.c motors have been around for about 15 yrs or more and i swear i have only ever replaced a dozen or so, THEY ARE WORTH THE MONEY.
a regular direct drive A/Cmotor pulls average 4-5 amps startup maybe 15 or more. and it cycles on and off how many times a day
your d.c motor pulls .8 amps.. it roughly uses about as much hydro as 1 100 watt light bulb
goodman sucks, you should go look at the collector box on your furnace right now !! it is the black plastic box that the ventor motor is attached to, 1 outta every 3 goodmans i see of that age are cracked, their heat exchangers dont last very long either. they have a seiries of rings that hold the halves of the exchanger together . they pop off and the chamber will open . not good !!
so then goodman buys Amana .they are better now cuz amana heat ecxhangers are almost bulletproof and do not fail. im sure it has happened but i have not seen it yet.
but i am still not impressed with the rest of the Amana furnace (only my opnion though ) time will tell.
carrier . was always the best, had some issues, class action lawsuits, the problems have supposed to have been addressed and corrected, when i have seen the new models trouble free for a few more yrs i will endorse them again. i always liked carrier
lennox ? used to be really good , they are not bad now, not great either, middle of the road,
keeprite ? same problem with heat exchangers as goodman. ring poppers, lifetime warranty on the ht exchanger 1 time, the replacement has 1 yr warranty ,
i replace ALOT of keeprite heat exchangers. the youngest furnace was 4 yrs old. in my opinion that just sucks. so this customers lifetime warranty on the heat exchanger just became toast . 5 yr old furnace with no warranty left . and that sucks,
rheem/ruud would not have one in my house no way.
colman/york. should have stuck to camping gear.
the list goes on from there.
so i myself have just purchesd some acerage and an older home and will be moving in next month.
it is a small bungalow 1100 sq ft the first order of business is to rip out a 16 yr old goodman mid eff . and replace it with a 2 stage trane high eff with d.c motors, and a new rinnia tankless water heater,
i might put the goodman in the barn but im not sure it will do the job. the barn/workshop is twice the size of the house
if you have not replaced or done anything yet pm me and i will try and answer any questions that you may have
