Hi all. I need to replace my ancient Lennox HS6 311 13FFC outdoor A.C. unit. It is connected to a Boyertown Hallmark LBD85 #2 oil furnace which I will retain. My home is a cottage size, 620 sq. ft., single story with returns in the floor and outlet registers in every room. I live in New York, presently a heat wave happening.
I've looked into some options but there is so much info I'm getting confused. Is a dry charged system the way to go? Any particular manufacturer stand out as better at this capacity/home size? The old unit has a 2.5 ton rating. Is this too much for a small home?
Thanks for any input, vastly appreciated.
