Sizing a Bryant Evolution heat pump
We have a rambler with basement, max size is 2100 sq.ft with nothing inside, factor in livable space and were right at 1700 sq.ft.
We have a 2 ton Lennox which is poorly matched to a 2.5 ton air handler, it work's but not that great. My unit is about 21 years old and it's time to go. I would like to install a Bryant Evolution but it's either a 2 or 3 ton as there are no 2.5 ton units.
I have 4 estimates, one says the 3 ton can work since the 5 stages can compensate. If my existing system easily cools when it's 90 deg outside down to 69 deg, would a 3 ton evolution 5 stage be overkill or will it work? I would like the extra BTU in the heat department as we get cold Mid-Atlantic winters.
Both the inside and outside units will be variable speed.
All input appreciated.

Even with variable speed, manual j, manual d, and manual should be used for sizing.
Duct work may be the limiting factor for tonnage, unless it's modified.
