If you have a geo  heat pmp, I assume you can use it for both radiant heat as well as forced air  A/C. Do you have two exchangers , one for heat another for A/C ? Of course you will need ducts for the A/C and tubing for radiant heat , how does that work?

Thanks,

Unit may have both an aircoil for AC and a watercoil for radiant. It won't do both at the same time

Waterfurnace has a line called Synergy - check it out.

Thanks  I'll check it out.
