I'm looking for some advice, please. We need to replace our furnace and A/C. We live in NJ and our house is a 1957 split level with about 2500 sf, not including the basement (where furnace is located) which is an additional 500. We also need to move the location of the A/C unit from the back to the side of the house (which didn't seem to be a concern).
We received 2 quotes so far:
The first was for a Rudd 90% 100K BTU, 4 ton, 13 seer. Price $x. A second price was given for an 80% 125K BTU, same A/C, for $x. I was told the Rudd systems are all variable systems.
The second was for a Goodman 80% variable 115K BTU, 3.5 ton, 14 seer (said runs as a 15 Seer?). He ran a duct calculation and said our ducts wouldn't support a 4 ton but he would update the coil to a 4. Price $x.
Are we better off with a 90% furnace and 13 Seer or 80% with a 14-15 Seer? Any thoughts on the size of the A/C? Is there any appreciable difference between Rudd and Goodman?
Any advice would be greatly appreciated!
