Buying new Furnace/AC units
I've been getting quotes for new Furnace and AC units. Any feedback/information would be greatly appreciated. I have decided to go with the Carrier Infinity 96 furnace and trying to decide on AC unit, the Comfort, Performance or Infinity series AC units.
I live in Chicago and have a 2-story Georgian, approximately 1366 square feet, with unfinished basement. Furnace is in basement and AC unit back yard.
So far, have gotten two quotes.
Furnace-Carrier 96.6% Two stage High Efficiency 80,000 BTU's, 3.5 ton Drive
AC-Carrier 3 ton 14 SEER High Efficeincy Condensor and A/C Coil (Puron 410-A)
White Rogers programmable thermostat.
Total Price; $9100.
Furnace: Carrier Infinity 96 Variable speed, 2 stage,
58MVC-60114 31/2 ton drive 60,000 BTU
AC: Carrier Comfort Series, 24ACB430-CNPVU30-17
21/2 ton, 30,000 btu
Humidifier: April Aire 600 Automatic Purifier
Honeywell Media Filter 16x25x5
Thermostat Honeywell 6000 Series-2 stage heat
or the Infinity Control
Total Cost: $9,439.
Add $100 for thermostat, $250 for the Infinity thermostat if he is unable to get the discount as offered in past.
Remove $1,000 from the cost if keep current 25x16x1 filter and casing.
How do these quotes sound?
Any recommendations on the AC unit? The comfort is cheaper, but the others are quieter and more efficient, with the Infinity series having a two stage compressor. Is this worth the extra cost?
Thermostat: am I better off going with the infinity model to take advantage of it's benefits?
FILTER: This is really a strange one to me. But one of the contractors is really pushing me to get a larger filter, the five inch as opposed to the one inch. Also seems to have to do with it having it's own housing and this being much more efficient in that the housing is sealed and even more importantly, has a wider area surface to filter the air. (He even offered to show me the filter in his own home to help me understand...I'm going to see it tomorrow.)
Anyway, wonder if anybody knows or has any input on this?
Thanks in advance and would appreciate any information, suggestions, etc. that you may have!
