Why Whole House Fans?

Whole house fans bring a breath of fresh air into your entire living space. Whether you’re looking to reduce the cost of running your air conditioner or improve ventilation to combat indoor allergies, whole-house attic fans from Air+Health blow away the competition. Browse our collection to find the perfect whole house fan for your needs.

How to size a whole house fan?

First determine your home’s square footage and ceiling height. Second, use our whole house fan calculator by entering your home’s square footage and ceiling height. The calculator will determine the airflow CFM (Cubic Feet per Minute) rate needed to cool your home. Two CFM rates will be provided:

 

1) EFFECTIVE cooling rate which provides the appropriate CFM level needed for a standard cooling environment

2) RAPID cooling rate, which provides a higher level of CFM to provide faster cooling

 

You can then match the CFM to our whole house fan models to find out which whole house fan is right for you.

Whole House vs. Attic Fans

You’ve got a lot of options when it comes to cooling your home. Central air conditioning does a great job of it, but the monthly bills for continuous A/C use can really raise your internal temperature — and install a new HVAC system is cost-prohibitive for many. In some climates, a window fan might suffice part of the year, but it won’t cut through steamy, humid summer air. So, which is better, a whole house fan or an attic fan?

 

Attic fans: Can cut attic temps by up to 50 degrees and living space temps by up to 10 degrees. Installed in an attic, these fans blow hot attic air out through a roof-level vent and prevent attic heat from transferring to lower floors. They’re not designed to cool the living space directly.

 

Whole house fans: Provide up to 20 total air changes per hour, depending on fan size, which can stir up enough air circulation to cool down your entire home. Installed in a central location, whole house fans draw in cool night air through open windows and send warm interior air out through the attic. As the sun and outdoor temps rise, turn off the fan and close windows to preserve the coolness.

How Much Does a Whole House Fan Cost?

Not sure what size whole house fan you need? Use our whole house sizing calculator tool to determine the size fan that suits your needs.

Is there a benefit to runing a Whole House Fan at the same time as a mechanical air conditioner?

No, there is no benefit and the whole house fan should not run simultaneously with mechanical air conditioning. Air Conditioning would be discharged outside the home which would drive up electric usage.

How much time does it take to cool down a house with a Whole House Fan?

How much time it takes to cool down the home depends on many factors including size of home, ceiling height, direction home is facing and number of windows. Every home is different. The greatest cooling benefit will occur when temperatures are cooler outside than inside. Plus, the greater the difference in temperature between outside and inside, the faster the home will cool down.

How do I determine which whole house fan I Need?

There are several variables in determining the fan you will need. Rule of thumb is to base whole house fan selection on the square footage of your home and your specific needs. Proper sizing will take into consideration the whole house in cubic feet (CUFT) and air changes per hour (ACH). See our whole house calculator or see answer below “Will I Feel a Breeze.”
