I've posted other threads today on my new split sytem heat pump. This thread is to ask about a 3.5 ton unit vs a 4.0 ton unit. Most of the quotes have been for a 3.5 ton unit. The latest Goodman quote was a 4.0 ton unit along with a 3.5 ton Carrier. He said for this SEER unit Goodman only had heat pumps available in even ton units.
What is the disadvantage of the 4.0 ton unit? Will the difference between a 4.0 ton unit and a 3.5 ton unit be noticeable in a humidity situation? Both systems are variable speed air handlers. Both qualify for the tax credit.
