Panasonic Ventilation Fans
Panasonic ventilation fans are engineered for 100,000 hours of continuous use!  Very quiet – and many models are Energy Star rated with a 3 year warranty. Why do you need to ventilate? Too much moisture can cause allergy problems and structural damage by encouraging the growth of mold, mildew, bacteria, dust mites, dry rot, and insects.

Our website offers information on how to calculate the proper-size fan for your project, as well as the complete line of Panasonic ventilation fans.

Whole House Fans are engineered to quietly and efficiently reduce the indoor temperature of your home. By running the fan all night long, you will wake up to a much cooler house! A/C units will start much later in the day. Then at night, turning off the A/C and running the fan will save you money.

Reiker Room Conditioner
The Reiker Room Conditioner, the ceiling fan for all seasons, is the ideal zone heating device. Current heating systems fail to address the few basic tenets that impact their efficiency: Heat rises; duct systems are inefficient ways to transport heated energy; and window glass temperatures must be taken into account if you expect to efficiently heat a room. The Reiker room Conditioner is a totally ductless system and is the first system to turn these negatives into positives. It is the ideal energy saving product for heating your home, office, condo or mobile home. The revolutionary design of the Reiker room Conditioner never allows warm air to rise, stagnate against the ceiling, and cool off. The Room Conditioner constantly keeps air in motion adding just enough heated energy to maintain your desired temperature.
