Hello,
I live in the Pacific NW and currently have a NG furnace installed by the builder in my attic. The unit is a 2006 Bryant 315AAV. I am adding AC and have purchased my equipment from an online retailer and I'm having a local HVAC company install most of it for me. I have purchased a Goodman DSXC180481 - 4 ton, 18 SEER, with 2 stages along with a CHPF4860D6 coil. The line set that I need to run is approximately 75 feet and will go from the second story attic down the exterior of the home to the backyard where my condenser will be. The retailer, and documents that I have reviewed indicate that a 1 1/8" suction line is ideal, however, my installer insists on using a 3/4" suction line because that's what he's always used for the many years he has been in the business. I'd like to understand what concerns I should have in using the 3/4" suction line and any advice/insight that you have would be greatly appreciated. Will this lower SEER rating and life of the condenser?
Thanks!
