I just got a quote to replace my heat pump system. I'm happy with the sales person; he did a manual load calculation and came up with around 44,0000 BTU/H (builder put in a 3.5 ton). He measured lineset, ductwork, etc. as well. Question: can a 7/8" suction line be used with a 4 ton unit? It's going to have to be used... He wants to put in a 4 ton regardless of whether we go with a dual stage or not (our home sq. footage is about 3500 he said) and we have over 30 registers. I was quoted 3 systems, the Bryant Evolution 16, the Trane XL15i, and the Trane XL16i. The prices are very, very comparable and all systems have a rebate. The Trane units would go with a 4TEE3F40 air handler (we can't really fit a *49 air handler in the basement). However, I just realized that the 4 ton XL15i and the 4TEE3F40 isn't an ARI-rated match, so I won't choose this option (unless he planned on fitting the *49 for this setup somehow). He talked about wiring issues with the Trane dual stage system; a new wire would have to be run. He wasn't pushy in either direction, which I like.
The quote includes:
-Bryant 4 Ton Evolution 16, Trane XL15i, or Trane 4 Ton XL16i
-Bryant FE4 air handler or Trane 4TEE air handler
-Evolution control or Trane TCONT803
-flushed lineset (new one would be very difficult)
-new pad, 3" pumps, disconnect, wiring, sheetmetal, etc.
-10 years parts/2 years labor warranty (extended available for extra)
Options (I think I'll go with both):
-F100 media air cleaner
-AprilAire (if we went with Evolution it would be Bryant's made by AprilAire) large bypass whole-house humidifier
So, any thoughts on which system to go with (XL16i or Evolution 16)? The ARI figures aren't terrible for both except for heating on the Trane of course (not even 3.5 tons with the *40 air handler - just over 3.5 tons with the *49 air handler).
