Pl.help to choose right HVAC system.
WeÃ¯Â¿Â½ve got following quotes for new furnace and ac. Existing system is abt. 20 yrs old York (ac 5ton 10 seer or so and 100000btu single stage furnace). Evaporator coil has major water leak and replacing it would cost some where near $1600-1700. All contractors said it can be repaired but of the opinion that since it is very old system its better to have newer more efficient system be installed. So got quotes now for different systems and bit confused which one to choose ( guess more options more confusion).
House is 3000SF two story. All HE system quotes qualifies for 700-900 reabte from state of NJ.
Also wanted to know why HVAC contractors offers only one brand?
IÃ¯Â¿Â½d really appreciate all expertsÃ¯Â¿Â½ help here to narrow down the choice.
A) Goodman GMVC95 HE, Variable speed furnace 95% AFUE, Goodman DSXC18 upto 18 seer AC.
B) Trane XV 95 120K BTU 95% AND Trane XR15 15 seer 5 ton ac. $11895.00
C) Rheem Prestige Series: 80% AFUE 2-Stage ECM Motor and 13 seer 5 ton AC. $8200
D) Carrier Infinity 2 stage variable speed furnace and 4 ton 16 seer AC.
$12500.00. Also this guy offers whole energy package which includes new bradford 40 gal water heater, sealing the attic to remove the draft in order to qualify us for state of NJ 10k 0% finance for 10 yrs. Looking at other quotes his price seems reasonable with extras he offers.
Please help us out to make right decision.
Thanks in advance.
