Frequently Asked Questions View all FAQs
How do you order the correct replacement parts?

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.
