    Trave vs American Standard Model Numbers

    I'm bidding a job where the other contractor is a Trane dealer; I install American Standard.

    Air Handler Question: The other contractor has submitted an air handler model GAF2AOB36S31SA. I cannot find that model number in Dealer Net, or by performing a google search (the closest found is model number: GAF2A0A36S31SA). Is GAF2AOB36S31SA a valid Trane model number; if so, what is the equivalent American Standard model number. I've checked with my AmStd supplier, and they, also, have been unable to ID the GAF2AOB36S31SA.

    Heat Pump Question: the Trane contractor has specified a heat pump model 4TWR3036B1000A. Would the American Standard equivalent be 4TWB3036B1000B (the builder’s model), or 4A6H3036B1000A (the Heritage line)?

    Air handlers should be 100% identical so likely a typo. The 4A6H3 would be the match to the 4TWR3.
