I plan to install a geothermal in Northeast PA. Primarily heating, maybe 10% cooling. I'd been planning on a 5 ton single stage Waterfurnace unit.

I looked at the waterfurnace and fhp web sites. Neither has a unit with a variable speed compressor - just the two stage scroll.
Does anyone have a geothermal unit with a variable speed compressor?
