Hi,
We live in Massachusetts and we are planning to replace our old HVAC. Our condo is of 1300 sq.ft with two sides surrounded by the walls of two other units.
We have got a few cost estimates from local contractors. For the AC we have got options from 1.5 Ton to 3.5 Ton , mostly 16 seers.
Can anybody suggest what would be the correct AC tonnage for hour house? Will 2.5 Ton be the optimum?

Thanks
