QuietCool Whole-House Fans vs. Running the AC: What It Really Costs

A central air conditioner can draw 3,000–5,000 watts. A QuietCool whole-house fan draws a small fraction of that while moving huge volumes of air. On a typical Fresno evening, that difference adds up fast.

Here's how it works: when the outside air cools in the evening, the fan pulls that cooler air through your open windows and pushes the hot air out through the attic. Within minutes, your house feels dramatically cooler — without the AC compressor running.

Most Fresno homeowners use the fan in the evenings and early mornings, then rely on AC only during the hottest afternoon hours. That combination can cut cooling runtime substantially over a Valley summer.

A QuietCool works with your AC, not against it — and because it also flushes superheated air out of the attic, it takes load off your whole cooling system.
