Can anyone guide me to a good duct sizing/heat gain software? I am looking for something better than just a air duct calculator. Thanks for any help!!

    Elite Software

    has a program for residential and light commercial size projects called, amazingly enough, "Duct Size" (How DO they do it??).

    What kind of duct calculator are you using? Charts or a circular sliderule?

    For all of my work and for over 30 years now, I have never used a duct program, just a Trane "Duct-u-lator" or the Loren Cook company equivalent. And I am fast. :)

    Do you have one? I can spot you one if you send me your mailing address. Give me 30 minutes with you and one of those tools and I will have you sizing more ducks than the Northeast Flyway can handle. Trust me.

    Sir Brad

    Thanks for the response. I have a Lima Air Duct Calculator. I am (ahem) a piping guy and while I have assembled plenty of tin (plenty of hand scars to prove it!!), I have not done much in the way of sizing systems.
    A ductulator lesson is definetly in order!

    Great time seeing you in NYC. You are a real gentlemen! Anthony and myself look forward to seeing you soon.

    Absolutely, Darin!

    It is the least I can do for you and your service. Fire off your snail-mail address to me and I will get a nice duct calculator on it's way to you soon. We can do a lesson over the phone although face to face is always far better!

    Yes, Friday (into Saturday) was a night to remember. Way too short. Looking forward to seeing you again and to meeting Anthony.

    And don't call me sir! I work for a livin'.... :)

    Lima calculator

    I like the Lima calculator for the return grille sizes on the back. The Lennox ( and more recently , Home Depot ) calculator has the eqivilant length of fittings on the back. Remember , residential supply duct is .10 static within 100 ft to the longest outlet ( linear plus eqiv. length ). Return duct should be based on 600 fpm ( velocity only as compared to equiv. length with in 100 ft ). Low velocity return ducts make for great residential ac and heat pump systems ( and commercial for that matter ). - FREEEEEEEEEAK !!!
