Have read all the IRS stuff (IRS Notice 2009-53) on the manufacturer "may" issue a tax credit certificate to the home owner who "may" use it as a tax record (guess than means if he gets audited). Have seen the manufacturer certifications on various web sites. Also am quite familiar with the AHRI certification directory.
Here's my problem. My distributor recommended an AHRI HP/3rd party coil/furnace that definitely passed the AHRI certification - coil happens to be 1-ton larger than the HP. This AHRI certification is not on the manufacturer's web site as one of their certified systems - not their coil I guess. Assumed that this would be rectified and accepted the proposal with a clause that requires the contractor to provide the certification before he even starts the install to protect my tax credit which was part of my economic decision. When I called the distributor (nice guy) to ask where my equipment is (another issue) he seemed quite surprised when I asked when I would get the manufacturer's certificate. Initially he thought that the 3rd party coil maker would provide the certification. When I described the manufacturer certification he didn't seem that familiar with it and even talked off-line to his sales manager. I even sent him references to the IRS notice and pointed out the name of the manufacturer's representative who signed their web site certificates.
This situation has got to be quite frequent. Am I going to get that manufacturer's certification?
Oh, he also warned me that I better get a copy of my AHRI certification because he has a letter that states that AHRI is going to restate their certifications by July 15, I believe, that reflects a new testing method. Huh!!!!! Where does that leave HO's that bought a system based on an AHRI certificate that has changed?
