    Try Manual J and D available through If you prefer PC work, use Right J and D software. Also, Invest in a good ductulator... You can play with different duct sizes and it will help you in your work.

    For residential

    Greeutings Denis,

    For residential applications, your best bets are Manuals J and D. Although more time consuming to perform, I am partial to the Manual D method and this is what I teach at the college.

    As far as seminars go, there will likely be some Manual D and Manual J sessions coming to a Long Island near you.

    Will keep you posted.
