Copy that on building one. I know that buying one in the states can be quite reasonable. A ground source is a different animal quite efficient. For 2100 sq ft in SC for ground source 2.5 would do quite well. But remember they are designed to run. Short cycling just runs up your electric bill

I would think that the 2 stage are really good for larger units 6 tons plus
