    AHRI Certification

    Can you help me understand the AHRI certifications? What does it mean if a heat pump is certified but there is no furnace listed? Confusing since every HP requires some kind of air handler.

    Is the "Indoor Unit" a non-furnace, air handler? Does it mean that one can get the tax credit only with a stand-alone HP and listed air handler??

    The heat pump & coil listing is for those using the existing blower unit, electric, gas, oil, whatever. The listing assumes so many watts per ton of capacity for the blower.

    On higher SEER stuff, the rating includes a specific furnace or air handler so exact electric usage of the blower is known and can be used to increase SEER due to low electric usage.

    Still a bit confused. I am looking at the Bryant and Carrier 18 and 19 SEER HP's. These are the highest SEER units either has. Despite the different SEER ratings, they are exactly the same unit according to the AHRI SEER, EER and HSPF ratings. Are you telling me that it doesn't matter what I use as the air handler, basically ANY furnace or any other means of pumping the inside air past the coil, these HP's are certified at the listed capacity? Or ??????

    If you find a listing, that only list the HP and indoor coil without an air handler. Then that listing is the one you use if you use a furnace/air handler of any other brand, or model.

    How many times must one fix something before it is fixed?

    beenthere, there seems to be some confusion on what a contractor can and can't do given such a certification. Some have to see the exact system certified before they will use it. That eliminates some nice systems because they refuse to read between the lines. Seems like there is a need to educate everybody to the same standard.

    They don't make it easy for any of us.

    They could put an instruction/guidence sheet with the AHRI lisings telling how to read the results. But they don't.

    As long as the heat pump & the coil are approved to use together, any blower can be used as long as it moves the appropriate amount of air.

    But if you want a utility rebate or tax credit, the exact model # furnace listed in the certification must be used.

    BaldLoonie, beenthere said the same thing elsewhere. I'll have to work on the proposers. Is there something in writing or on the web or ???? that says this is acceptable?

    Thanks, guys.
