Ceiling Fans vs Air Conditioning: How Much Can You Really Save?

A ceiling fan uses roughly the power of a light bulb, while central air can use 3,000 watts or more. Fans do not cool the air, they cool people, so the savings come from raising the thermostat.

The four degree rule

Most people feel just as comfortable at 78 with a fan as at 74 without one. Each degree can save several percent on cooling costs during California summers.

Installation matters

A fan needs a fan-rated box, correct blade height and a dedicated switch leg. Our ceiling fan installation service handles new wiring where no fixture exists.

Pair it with LED

Swapping fixtures during a fan install is efficient. See our lighting installation page.

Find your city on the locations page to book an install.
