    Would anyone know what the difference between a Comfort-Aire HEV036 Rev A and Rev B unit would be in a 3 ton model? It must be something in the heat exchanger coax coil as the manual only has pressure drop data for the Rev B units in 2, 3 and 5 ton units for Rev B not Rev A.

    Didn't know anything about comfort-aire, so I looked up specs.

    No clue, but it does say REVA and REVB are obsolete and REVC is current.

    From what I can see the unit looks like a slightly less efficient Tranquility 3o from climate master. A lot of the same controls. 5.4 COP in stage 1 compared to 4.6 and stage 2 is 5.2 compared to 4.3. Maybe 2000 more BTU from the Tranquility compared to comfort aire.
