Lennox Model Numbers...............................(Starch)

John StarcherJohn Starcher Member Posts: 794
....quite a long time ago with a "decoding" chart for lennox model numbers, and how they relate to equipment size. Specifically, I'm looking at a HS29-261-3P condensing unit.

What is the BTU rating of this unit???

    hope this what you're looking for

    Lennox equipment:

    211= 1.5 ton, single phase
    261= 2 ton, single phase
    311= 2.5 ton, single phase
    411= 3 ton single phase
    413= 3 ton, 3 phase
    461= 3.5 ton single phase
    463= 3.5 ton, 3 phase
    511= 4 ton single phase
    513= 4 ton 3 phase
    653= 5 ton 3 phase

    Lennox model numbers

    14= 1 ton
    21= 1-1/2 ton
    26= 2 ton
    31= 2-1/2 ton
    41= 3 ton
    46= 3-1/2 ton
    51= 4 ton
    65= 5 ton

    So, your unit is a two ton model.

    The HS stands for high side, HP for heat pump. The next two numbers are the series of unit, they generally work up as they introduce new models. Then a dash and the next two digits which are the capacity, see above. The third number between the dashes indicates single phase or 3 phase, a single phase unit in your case. And the last numbers after the next dash will be the series number and sometimes a letter which indicates the voltage

    So an HS29-261-1P is an air conditioner, 29 series, 2 ton, single phase, first revision (we call that the dash number, important when ordering parts) and the P stands for 208-230 volts.

    Hi. Anyone know if you can buy a new one of this model (HP19-261-3P) or at least a replacement?

    Thanks. Garry

    the hp19-261 is a r-22 hp 12 to 13.5 seer depending on indoor coil. replace with any 13 seer r-22 unit dry charge. If you can still find one.
