One room too hot while another is too cold? Not with Aprilaire Zoned Comfort Control.  The Aprilaire Zoned Comfort Control system increases comfort by controlling specific temperature needs in designated areas of your home — making you and your family more comfortable while saving money by using less energy for heating and cooling needs.

Aprilaire Zoned Comfort Control is a system of more than one thermostat, electrically connected to a control panel which operates a number of dampers in your forced air heating/cooling system. Conditioned air is then distributed to various parts of your home as needed. The system can be installed in new or existing homes helping you achieve total indoor comfort. Plus there is no service required — only changes in living habits may make it necessary for system adjustments from time to time.
