Hello,

I have to make a decision regarding a new project, and maybe i could use a third party opinion:

Current system is a 4 ton Fraser Johnston (Westinghouse) unit that is getting tired. The house is 2 story, with lots of vaulted ceilings, and we are planning on zoning the new system with 3 zones. I have talked to 4 contractors and received the suggestions below.
I'd appreciate any feedback on these units. I'm confident on the contractors, though contractor D spent quite a bit of time measuring the room sizes and current duct and register sizing. He gave the most complete report, by far. System reliability is a big importance here, will most likely purchase a labor warranty. The manufacturers are Trane, Coleman, Lennox, Goodman, Carrier, and York.

Thanks in advance,

Contractor A:

I would choose option D1....very efficient system and it sounds like your contractor did his homework.

The Affinity is a nice system with a great HSPF, you will enjoy the comfort.

I agree. I would go with option D1. I have used that system before and loved it. It's very efficient and dependable. I also like that the contractor seems to be on top of things. I would anticipate that you would be satisfied with his work by the sound it.
