Question

Will a 2 1/2 ton central a/c/ cool a 1300 sq. ft. 2 floor home?

Answer 1

It also really depends on your climate.   I have 1600 sq ft home (1f) and a 3 ton could not keep up. I replaced it  with a 3.5 ton Lennox and it works great.  I have a high ceiling in the den.

But I live in Texas.  One rule of thumb I have always heard is you need a ton for every 500 sq ft.  So I would think 3 ton unit

would work better.

Answer 2

sounds good . , and if not then just keep the a.c on longer and lower

Answer 3

A two and a half ton unit should do just fine. Unless the house is not well insulated, or if the trees offer little direct shade, then a 3-ton unit might be more appropriate.

Answer 4

That sounds like it should be sufficient.  The more ideal situation would be to have a 1 1/2 ton unit for the bottom floor and a 1 ton for the upper floor, but a single unit should suffice.
