Please help with sizing of these new units.

Carrier heat pumps

CH13NA043-B
CH13NA019-B

My guess is 3 1/2 and 1 1/2 ton

The home is a new 4600 sq ft construction.

A total of 5 tons seems a little small.

Thanks

Looks to be a 3-1/2 and a 1 ton and I can not say its undersized don’t know the make over of the construction but it better be well insulated;-)

You are correct 3 1/2 and 1 1/2. Just ran into this same configuration and looked them up in the manuals
