Morning, does anybody know where I can get a online version of a manual J & D

calculators. This may be asking alot but free?

    Manual J

    Do you have a blueprint? I can do the calculations for you. If you are interested in the calculation process yourself, you can try the One-time version of HVAC Calc.

    Joe, this is a design and build retrofit on new construction.

    The owner went with a LG 36000 btu multi condenser split system

    With two mini air handlers. He did not want to use the factory direct wall mount

    unit. They want to have every thing done contrary to manufacturer specs.

    That is way I would like to get the manual D.
