The load calc indicates a need for a 120,000 BTU unit and a 4 ton A/C. The units would replace a 120,000 BTU that was original to the house (1982) and a 3 1/2 ton A/C that was also original to the house (1982). Since the house was built, there is an additional 300 sf or so, with a total of almost 3,300 sf of space.
There is a fair amount of work to be done in connection with any installs, including a lot of venting/piping for the furnace and the A/C, as well as lining our chimney to handle only the hot water heater. In addition, we will certainly require some damper adjustments.
We have been quoted $6,500 for an install of a Carrier 58 MVP 120 and $6,300 for an install of a Carrier 38 TDB (16 SEER).
These prices seem high, but they are actually lower than pricing we received on comparable (equivalent?) Bryant equipment.
