THAT'S HOW COMFORT GETS DONE!
During heating season the FanHandler tames that high speed off/on blower. You only get the amount of air coming from your registers that you need. Air is always circulating. Always at a comfortable speed for the temperature being delivered. Your electronic air cleaner, filters, humidifier, UV germicidal lamps, and any other added equipment is always working at peak efficiency. Temperatures throughout your home become balanced. Drafts down stairways are eliminated. That cold draft when the blower first comes on is gone forever.
HERE IS AN INTERACTIVE DEMO for OFF-ON Blower Cycle
If this seems familiar, then you need a FanHandler!
