Bought a $30,000 Geothermal system in 2010. I paid and had my HVAC unit serviced every six months at a cost of $140 per visit.
A valve (TVX) broke making the unit useless. The installer/servicing company informed me that there is a limited "allowance" for this repair. I called WaterFurnace, the Regional VP, coperate headquarters and no one wants too stand behind the product. WaterFurnace only paid part of the repairs leaving me wiht a huge bill!
(I thought a ten year warranty, which sounded good, would cover the product. Don't you???) Stay away from this company!
