Custom Wine Cellars by Joseph & Curtis. Flush Mount Heating and Air Conditioning Booster Fan, White - HC500-W. Depending on the season, lowering or raising your thermostat just 4° can cost an additional $35 to $50 per month.
Running the Heating and Air Conditioning Booster over the same period only costs about 60 cents! Unlike a traditional booster that simply mounts over your existing wall or floor vent, this device has been designed to replace a standard 4" x 10" vent for a professional flush mount finish.
