Before ordering replacement parts, make sure you have the fan model and serial number.
Where can I find instructions to wire a motor on my fan?
The nameplate of the motor includes a wiring diagram. Wiring diagrams can also be found beneath the motor image in our Buy Parts section. Simply click the wiring diagram icon to view it.
Can I install a thermostat?
Yes, but only if the thermostat has a simple on/off operation. Please note: if the thermostat varies the amount of voltage delivered, it will damage the motor and void the warranty.
Can I install my whole house fan vertically?
Comfort Cooler (CC) series whole-house fans may be mounted vertically, however, the AS and CSS shutters will not function properly in the vertical position. We do not carry a ceiling shutter for vertical installation. Vertical installation instructions.
The HeatBuster is one of the most rugged and dependably built, full service belt drive fans on the market and is engineered to provide decades of service.
