The contractor we are dealing with has his own formula for the size of coil: figure out the ton needs per the climate data, and make it bigger. My brother's system would work with 2.5 tons. He is getting a two speed 3 ton.
600 ft loop of 3/4 pex per ton. 1 square foot per foot of pipe. 1800 square foot excavation 6 feet deep.
His system will run most of the time as a 1.5 ton.
