Did he add refrigerant to it?
3 ton on 1600sqft doesn't sound undersized to me based off of the old timer method, but a gazillion different things can factor into what size you need.
Yes. He said it was such a small amount that he didn't charge me for it. I guess he was being straight up because the price didn't change and this was a re-up on the yearly maintenance contract. He did mention that the unit in the basement is a 2 ton. Is that ok to have a mismatch like that?
