Bought a 5 Series geothermal system (trying to be a better environmental steward). System worked well for almost 10 yeas. Then we had a leak of the polyol ester (poe), and oil found in r410a refrigerants, into our domestic water supply, I.E. all the water piping in the house (proven by spectral analysis). Contacted WaterFurnace to help identify the problem, come up with a solution. Stone walled, denied this could happen, maybe could use the warranty or just a courtesy assist. Brick wall. Called to help with testing the house water after we replaced all the plumbing in the house to hopefully rid the system of the poe. Another denial that this could have happened, mind you we have chemical analysis proof! Highly recommend you use another company for your Geothermal needs.

"Nothing but problems"

We had a Waterfurnace installed in 2008. During the first four years, we traveled much and did not really use it. After we started living in the house and we used it more, there has been nothing but problems. We have likely spent over $10,000 in various repairs. Many of them came just after warranty. Overall, it's hard to find service and repair companies. In the Seattle area, there is only one, and pricing is thereafter. This repair company recommends to get a new unit, which they priced at $15,000 – $20,000 to install. I would never use this brand again. Poor service. Unit will fail. Hard to find service people when it stops working, which is typically mid winter or peak summer temps.

"Great technology"

5.0 rating
Very Satisfied

I am very satisfied with my geothermal unit. It lowered our utility bills by about 50% and is extremely comfortable. I took the time to find a well qualified installer with great references. Many of the complaints I've heard about geothermal are due to improperly installed equipment – not the hardware. Most of the components in these systems are found in normal air conditioners and heat pumps. A++++

Great sales pitch to buy but then winter comes. I see all the great reviews are from new owners… Wait just a few years. The only thing green is what it costs to run after is starts to break down and run on emergency heat! And good luck finding a repair person. My installer after the install became MIA! (Executive Heating) Waterfurnace recommended a second repair company who showed up to analyze then must have run off with the original installer. (Cappy Heating) Don't be fooled like I was to go with this System.

"Repair problem"

I am no without heat for one month. 7 degrees in northeast Pennsylvania. The local repair folks have been great. The Waterfurnace central repair cannot figure out why it is not working after seven years of no problems. It is under warranty. There seems to be no urgency in replacing the system. Be sure this is not your only heating system
