Seeking advice as to strength of my case. Have documented most everything. Stack of paper/emails is enormous. Here are basics: Geothermal system installed 5 years ago. WaterFurnace NDVO38. One closed loop. Countless lockouts for freeze detects mainly, one for comp monitor, each year. Repeated service calls and visits (initially paid for these and yearly preventative maintenance contract, in later years no charge for these visits/parts). You name it we've had it assessed/replaced: --countless loop flushing (including initial situation with pipe in basement coming detached and glycol spilling throughout utility room) --changes to staging of equipment due to manufacturer problem (soon after install) --replacement of failed Intellistart (only 3 years old) --A preventative maintenance visit that we requested in which technician did next to nothing. Company told me he was new and didn't do these visits, as usual technician was out. Company had technician return to house to do requested work. --Heat exchanger replacement (4 years old). Much investigating to determine this was problem—initially circulator pump and “air in pipes” thought to be issue --More freeze detects this January and company owner came and merely increased aux heat (significantly). Had to request follow up to reduce as heating bills extremely high. We are now being told that heating/cooling loads are too high for house and second loop needs to be installed and possibly upgraded system (NDVO49) Company owner is not offering to pay for digging, and necessary repairs to landscaping, stone work, irrigation system. Owner claims we did not furnish him with accurate info about our conditioned space for his Manual J heating/cooling analysis. Important to note that owner also does solar install. Gave us a hard sell for putting panels on roof. We sought second opinions from three solar companies who all said interference from numerous trees in yard did not make solar a good option for us. Input/feedback/help would be most appreciated. Thanks for reading.
