    Arzel Zoning 1st Floor and Basement

    I had a company come in today that sells Arzel zoning equipment. They said to zone the 1st floor and basement they would insert dampers into each supply currently to the 1st floor. To service the basement they would tap the main trunk and have to split one supply to the first floor. They would add one return to the basement

    Is this the way its done?

    Do they know there is going to be enough air flow to properly service the area?

    Just really need the zoning for heat as the basement is cool in the summer

    Thanks

    How many times must one fix something before it is fixed?

    It sounds like you have a ranch and you're trying to heat the basement during the winter.

    If you have seperate supplies to the basement or if you need to add supplies, then the dampers will go into each supply run (main floor and basement).

    Or a seperate trunk line with supply runs could be run for the basement to lessen the amount of zone dampers.

    If it's a large ranch, you may want to seperate the living area from the bedrooms. Each with their on thermostat.

    Arzel Layout

    It sounds right to me.

    The Arzel system works by controlling the airflow to your home with a series of dampers. Your contractor will recommend a dampering solution that provides you with control of your whole system. The Zone Control will then open and close those dampers as required to serve the demands of the thermostats in the space.

    Zoning will deliver more airflow to the area that is calling, while managing any excess air.

    You should notice significant increases in comfort and potentially energy savings at the same time.

    Good chance that they can find another way, instead of using that many dampers.

    The beauty of "Branch" dampering is that the home owner now has options in regards to adding a zone (or two) when they realize how much more effective their HVAC system is working. The "Trunk" dampering method would force the contractor to add another trunk in order to add another zone...very costly.
    We actually have contractors that install a panel with an extra zone because they have had so many home owners that have called them back to add another zone once they lived with the results. Separating the master bedroom is a very popular request.

    Looks like the contractor is already adding another trunk for the basement.

    You're exactly right. I always gave the homeowner the option of going with a 3 or 4 zone panel (very small upcharge) so they could add a zone later if, desired.

    I did not interpret it that way...but you could be right.

    I agree with beenthere.

    Zoning has it's benefits, in certain situations/applications.

    I don't believe a ranch with a basement is one of them.

    Installing bypass damper will allow some of the supply air to enter the return air so that the system will operate within appropriate velocities.

    Zoning is excellent for improving temperature control by floor. Perhaps overkill for a bungalow.

    Arzel uses air actuated dampers instead of powered motors. When the ceiling is finished no chance for motors to fail!

    I believe Arzel recommends you don't install the dampers where they can't be reached for service later.
