I am currently facing the most frustrating purchase decision of my homeowning career. (whopping 3 years). I have a 1,453 SF house outside of Greensboro, NC that was built in 1990 with the original split system running on natural gas.
My furnace is not broken, although I feel like i'm on borrowed time, and the AC unit had a hard time keeping up this summer on hotter days. With natural gas prices going up, and the overall age of the system I feel like I should replace it. However, we only plan on being here another 4-5 years.
Issue #1 I'm unable to obtain any efficiency information on my current system:
Mfg: Snyder General Corporation
Furnace model: DGHA100A016BN
AC model: H801030
Issue #2 If I am to replace the system, what do I replace it with? I've had four different contractors suggest four different setups. I could not possibly be more confused.
Trane dealer A: Gaspack 12 seer; 8 HSPF & reconfigue all ducts
Trane dealer B: Dual fuel 13 seer; 8.5 HSPF; 91% AFUE
Amana/Goodman dealer: replace existing split system w/ 13 seer and 92% AFUE
Bryant/Carrier dealer: heatpump only
Any advice or wisdom is much appreciated.
