Location: North Florida, coast
1 story stucco
Sq ft heated/cooled: 2283
Current unit Trane 5 ton and 12 yrs old
I've had five contractors come to quote systems. Two "ball parked" the estimate; one says he will send me the load to confirm his quote. Two did the full job (measurements, loads, duct inspections, asking questions, etc.); both refused to quote for Goodman (my request, very strong opinions against) so I cannot get a full apples to apples comparison. But here is what I have:
Install 20" return, upgrade current supply (10" and 14") to 2x16", 18x18 boot, 2500CFM duct cleaning, any resealing, UV lights (dual), digital thermostat, new pad to code, breaker change as needed, new copper refrigerant lines, AH stand, MERV 16 filter box, heat strip
Comfortmaster 3.5 ton N4H342 paired with FVM4X4800 AH (low quote)
Comfortmaster 4 ton C4H3 paired with same
Comfortmaster 4 ton C4H748 with FVM4X600AT1
Bryant 16 seer dual speed (cannot read model or AH) - same price as above and we did discuss this was a variable speed unit
Upgrade returns and supplies to correct sizing, copper lines, new pad, UV light (single), duct cleaning (sisal with vacuum), heat strip, digital thermostat
Lennox 1414X048 15 seer/CBX2764048 AH 2 speed
* I need to pay for breaker upgrade
I am concerned that Contractor #1 is insisting I can get the comfort I need in a 3.5 ton unit in the lowest priced option and not raise electrical costs; I prefer to lower them. I feel we need a 4 ton based on sq ft; yes, I am aware of how a 2 speed compressor and variable speed air handler operates.
So what say you?
