Heat Pump Selection

I am building a new house- 2 story, 2820 sq. ft. 1st floor 1684 sq. ft, 2nd floor 1136 sq. ft. House is basically a rectangle in shape. Location is north Texas (DFW area).
I realize that an HVAC (heat pump) sizing estimate needs to take into account a lot more information but I would like to get a general consensus on what size unit I should select. I am guessing 13 to 16 seer, in the 4-ton range.
Again, this is for a heat pump.
Thanks in advance.

Heat Pump Selection

I'm not a HVAC pro. I believe the HVAC professionals (I do not have many where I live) will tell you that a heat gain/heat loss must be done on the house.

A heat gain/heat loss takes into consideration many factors such as square footage, individual room square footage, number of windows, type, and size, exterior doors, type and size, wall, ceiling, and floor insulation, building orientation to the sun, an on it goes. No guessing allowed. HVAC is science! Be sure the company you select does one.

Heat Pump Selection

Depends how well built the house will be.

A spray foamed house might only need 2 tons. A loosely built house could need 6 tons.

Another person on another forum built a house in Texas, 4,000 sq ft, cools it with a 2 ton A/C.

So best to have a load calc done, so your not over or under sized.
