I spent a lot of time on this forum back in 2009 while I tried to get a duel fuel HP system that would handle our large house AND meet the Federal Energy Tax Credit requirements. Finally found a York SEER 18 HP with NG furnace Got it installed in July 2009. The system is: a 2-speed compressor York Affinity YZH04811C dual fuel HP with a natural gas, variable speed YP8C10020MP11 NG furnace/air handler and a large matching 10-year warranty, Model MD-CC60E44-245L-036 Aspen coil.
The vent temps were warm this spring (and maybe even sooner) so I measured them at around 74 degrees for 3 dispersed vents and a temp at the HP fan of only 93 (seems like it should have been much hotter in hot weather). Since both the original contractor had retired and even the York distributor in business for decades went out of business. Long story short, after hours of time and lots of nitrogen, etc. the new contractor isolated the problem to the Aspen coil and the system had already lost over 1/2 of the required 13 pounds of 410A coolant. I am looking at diagnostic time/materials, remove/install coil, recharge system and test of close to $ and that is not definite since the contractor is leery of the large coil and the working space, as well as, locating the new coil.
Aspen has offered only to let the contractor find an OEM coil at a supply house that they finally agreed on. Since this is a high-efficiency system and coil I am very concerned that just any coil will not match. The duel fuel system and original Aspen coil meet the tax credit under ARI Reference# 3227959. Trouble is that Aspen does not make that coil any longer. I am NOT an expert but I went to the AHRI Certification Directory and found ARI Reference# 4581661 that seems to meet the requirements. I have been insisting that Aspen state the certification that is required. Is this a correct position?
I also feel that I have been made a fool of if I pay the kind of costs that were caused by their failed coil in only 4 years. To be more accurate, the first winter I hardly used the HP because York had a HP controller board problem on this new system that took that long to diagnose and correct. Also, this last winter I ran the system mostly on NG because the location of the tstat in a sun-drenched room caused it to be happy and some other bedrooms to be cold. With the son and his family there it was unacceptable to run the HP until I finally, using this forum, identified appropriate remote temp sensors for the excellent Honeywell VisionPro tstat and figured out how to install just 2 of them. So this coil hasn't even realistically been used anywhere near 4 years. What are your thoughts on me getting Aspen to cover much more than a suitable coil and maybe $50 to me and the new supply house and what percentage of the cost is realistic to get them to pay (I am going for 100% as my starting position, but having a real problem getting them to talk to me, even to specify an exact coil)?
I would much appreciate expert opinions and advice on this difficult issue. The house is hotter than .... and the progress seems very slow. Thank you for your help.
