Start With the Home
A More Comfortable Home Starts With the Right Fit.
Tell us where heat lingers and how you use the home. We can help you decide whether a whole-house fan belongs in your cooling plan.
Your Home Stays Warm Into the Evening
If the outdoor air has cooled while rooms remain warm, it may be a useful time to bring that cooler air through the house.
You Want Another Cooling Option
A fan can complement air conditioning when conditions are suitable. Your home, weather and operating habits determine how much you use each system.
You Want the Installation Planned Properly
Equipment, location, electrical work and controls should be considered together. Start with an evaluation of the home and a clear installation scope.
How It Works
Move Cooler Air Through the Home.
A whole-house fan uses outdoor air to cool the living spaces. It needs an open air-inlet path and a suitable way to exhaust the warmer air.
Open the Required Windows
Use the window openings specified for your installed system so outdoor air can enter.
Draw Air Through the Rooms
The fan moves that cooler air through the home toward the intake grille.
Exhaust the Warmer Air
Warm indoor air leaves through the planned exhaust path, commonly a properly ventilated attic.
Use It When Outdoor Conditions Are Suitable.
Run the fan when outdoor air is cooler than indoor air, with the required windows open and air conditioning switched off. Follow the instructions for your installed equipment.
Keep it off during wildfire smoke or poor outdoor-air conditions. A whole-house fan draws outdoor air into your home.

Before Choosing a Fan
The Fan Needs to Fit the Home.
Square footage is a starting point. We also look at where air can move, where equipment can be installed, and what the electrical work will involve.
The proposal should explain the fan, installation location, controls and any additional work identified during the evaluation.

Common Questions
Whole-House Fan Installation FAQs
Will a whole-house fan replace my air conditioning?
It can reduce the need for A/C when outdoor conditions are suitable, but it does not provide refrigerated cooling. Your home and the weather determine when each system is useful. Use the fan and A/C separately.
Do windows need to be open?
Yes. Open the required windows before switching the fan on. The amount and location of those openings depend on the installed equipment and the home's layout.
Is this the same as an attic ventilation fan?
No. A whole-house fan moves air through the occupied rooms and exhausts it outside, often through a vented attic. An attic ventilation fan moves air through the attic itself. Tell us which space you want to cool so we can discuss the right service.
How noisy is a whole-house fan?
Sound varies with the equipment, fan speed and installation. We discuss location and noise preferences when selecting a system; ducted designs and appropriate mounting can help reduce noise in the living space.
Can I use it when the air outside is smoky?
Keep the fan off during wildfire smoke or other poor outdoor-air conditions. Because it brings outdoor air inside, it should not be used to ventilate the home with smoky air. Follow local air-quality guidance.
How much will installation cost, and how long will it take?
The equipment, attic access, installation location, ventilation and electrical work determine the scope. We confirm pricing and scheduling after reviewing those conditions. When you contact us, share the approximate home size, number of stories and any fan model you are considering.
