Adding Zone Controls to Heat Pump

Hi All,
I recently built a new home and had a Lennox heat pump installed and its working very well. There is a main level and a finished basement. For heating, the basement is a bit cool relative to the main floor - no surprise there as there are no zone controls. I am able to manage this somewhat by manually closing the floor vents in the main floor level and opening the ceiling vents in basement. This allows the hot air to rise and somewhat balance things out.
It would be nice if I could essentially do this automatically with a 2 zone control system. Is there any practical way to add this to my existing system? I have a Robertson thermostat now and would like to add a second thermostat downstairs and motorized zone dampers.
Thanks,
Paul

You proposed project is not for beginners. As far as a practical way to add it to your system, I can't *SEE* it through the computer, nor can anybody else. What did your local HVAC guy tell you?? or have you asked him??

Happy Winter Solstice to you and your family.
Zoning is an "added" benefit for a residential comfort system, and is not designed to correct any deficiencies in the duct design of a system.
By closing off some vents, you are limiting the amount of air that is available for the equipment. [Not recommended.] I understand that it is hard for you to understand, but the truth to the matter is you can't close off registers and expect air to make up in other area's. If the duct system is designed well, then closing off registers only limites to the *total* system air delivery. Your system's total performance is dependent on the correct amount of air.
Zoning can increase a systems comfort and efficiency, but the duct system must first be designed without zoning. Then adding the zoning will increase the comfort level.
I'm not going to give you a lesson in air properties and movement, [not that there isn't books on the subject.] Contact your local HVAC company, and tell them what you want to do. Get some prices from three different contractors recommended by family, friends and relatives.
