Helpful Tip: Beware the Oversized Kitchen Exhaust Fan

Homeowners often select oversized kitchen exhaust fans not realizing that they require makeup air - adding considerably to the cost of their house project.

A sales representative may not even mention the “make-up air” issue at all and the the homeowner can subsequently experience some serious sticker-shock at the cost of make-up air.

For example a 600cfm fan requires 10kW of heat to temper the air.

This amount of makeup air represents the capacity of an entire electric furnace in a small home.
