Based on the following would you recommend the 2000 cfm blower for the Carrier infinity gas furnace that is speced?
My current system is an 19 year old 4 ton Lennox A/C and a 24-25 year old 120,000 BTU York gas furnace in a house built in the early 1930 with two returns in the larger rooms and one in the smaller bedrooms. The house is located in washington dc and is pretty poorly insulated --blown in insulation in the attic and storm windows is about it. Plaster outer walls get pretty cold in winter. The house has about 2700 square feet of living space over two upper levels and a finished basement. Thanks for all the help and input. Any comments or suggestions appreciated.
Here is what the contractor has recommended for the retrofit:
Carrier infinity Furnace: 58MVB 100-20
Carrier infinity Condensing unit: 24ana748--four ton
Carrier COIL: CNPVP48
Carrier INFINITY CONTROL: SYSTXCCUIDO1-A
