Hi all, I posted earlier about some estimates we got. We got another one on a Trane today but this contractor is suggesting a 2 ton outdoor unit (max our electrical system can handle) paired with a 2.5 ton coil. He says this would cool better. Until the current coil failed on our 25 year old 2 ton Ruud, we didn't have any trouble keeping the house at 80 which is fine for us while we're home. (we live in the DC suburbs, so summers aren't particularly brutal, just humid) Does it make any sense to mismatch like this? None of the other contractors suggested this. What would the benefits to this be? Possible drawbacks?
