I live in MD. I am replacing an old 3.5T heat pump system. I have the following quotes.

Carrier

#25HPA542A31, #FV4BNFOO5T00, #KFCEH3101C15 - US$ 5400

American Standard

#4A6H6048C1000A, #4TEE3C06A1000A, #BAYHTR1415 - US$ 5950

Bryant

265ANA042A, FE4AN005 + Evolution thermostat, 20KW heater - US$6950

All have 2 yrs labor warranty and 10yrs on parts & compressor.

Can someone advise me on which one should I go for?
