Company Overview

Whole House Fan Company is a family-owned contractor with deep roots in California, operating since 1980. For over 45 years, we've been dedicated to perfecting whole house fan technology, driven by a personal belief in their effectiveness. We started in Sacramento, originally installing standard paddle-blade fans, but customer feedback about noise led us to innovate. We now design and manufacture our exclusive, powerful ZEPHYR blade and partner with QuietCool, offering the two most advanced systems available. Our six branches across the state allow us to provide San Dimas homeowners with energy-efficient cooling that can slash AC costs by up to 90% while improving indoor air quality. We've also expanded into insulation services to ensure our fans work optimally year-round, keeping homes cool in summer and warm in winter. We personally use and recommend these systems for every home.

Q&A

How does a whole house fan system work with my existing HVAC in San Dimas?

A whole house fan is a complement to your HVAC system. In our San Dimas climate, you can use it during cooler mornings and evenings to pull in fresh air and flush out hot, stale air, giving your air conditioner a break. This can significantly reduce runtime on your AC, helping to prevent common issues like capacitor strain and dirty evaporator coils from overuse, while lowering your energy bills.

Why is professional insulation installation important for a whole house fan?

Proper insulation is key to maximizing your fan's efficiency. Our insulation services ensure the cool air brought in by your whole house fan stays inside during our hot summers, and that your home's heat is retained in the winter. This creates a more stable indoor temperature, reduces the workload on all your systems, and helps you achieve the maximum energy savings from your investment.

What makes your whole house fans quieter than traditional models?

We addressed noise complaints head-on. After years of installing standard fans, we engineered our exclusive ZEPHYR blade, designed specifically to operate more quietly while moving more air. Combined with our advanced QuietCool systems, our fans provide powerful, whole-home ventilation without the disruptive noise associated with older paddle-blade designs.
