Can I replace all of the vents in my home with Smart Vents?

Yes you can. We recommend replacing at least 1/3 of the vents in your home with Smart Vents, but if you do replace every vent, be sure to leave at least one Smart Vent open to keep air flowing through your heating and cooling system. If you don't replace every vent in your home with Smart Vents, we suggest leaving your standard vents open at all times.
