Looking for a little advice. Looking at a couple of geothermal systems; 1) A Carrier GT-PX 3 ton spilt unit vs. a Waterfurance 3 ton unit. This is going in a 2300sq ft home. I have a 2.5 ton A/C unit now and have no issues cooling the home, but the unit is now over 18 years old. Also have a 90+ Lennox unit that will stay in place and be incorporated with the system (3 years old). Just wondering which unit would be the best buy? The quote for Waterfurnace is a couple of thousand higher.
Also I have room to put a horizontal or vertical loop in. Is there any real difference in them?
Thanks for the help!!!
