Replacing 25 yr old Trane XR800 2 ton - Need advice
Central Arkansas, mild winters hot humid summers
Replacing upstairs Trane XR800 8 seer unit that is 25 years old.
1100 square foot upstairs,
Installed in the attic
Manual J - shows a need for 16,000 btu and 1.4 tons cooling at 70% SHR and 1.2 at 80% SHR. If I am reading this correctly
I have been quoted the following
TDHIB040A9241A - 95% furnace/40,000 BTU
4TXCB025BC - 2 Ton Cooling
4TTR5024 - 2 Ton Condensing Unit, 15 Seer XR15
1-TCON 800 programable thermostat
Total cost $4999.00 plus tax. Not counting local utility rebate of $600 for the 95% or higher furnace.
One year free service,
10 yr warranty on Compressor, cooling coil. Furnace heat exchange - lifetime
All prices include installing new aux drain pan with float switch, new outdoor concrete pad, flushing lines, new return plenum, and bringing the service platform up to code.
My concerns are humidity. I am afraid that this will cool too quickly and not resolve humity.
Is the furnace to large?
I have heard some concerns about putting a high effenciency heat unit upstairs in the attic. Some say there is issue with the unit freezing.
Does this make sense?
