A worthy opponent of air conditioners, a whole house fan also conditions the air, improve air quality, cools temperature and maintains humidity at decent level.

To begin, we’ll define what a whole house fan is and how it differs from a standard air conditioner. Afterwards, we will clarify you how to pick the correct size whole house fan and how get it installed in your house.


What is a whole house fan:

A whole house fan is a huge fan located in a home’s attic. It draws warm air from your home up into the attic., which is then forced out through attic vents in the roof, creating a pressure in the attic. It also functions as a ventilation system for the entire house. The system is located in the attic and is connected to the highest floor’s ceiling.

The air is drawn in through open windows and exhausted through the attic and roof by the whole house fan. In addition to adequate attic ventilation, it offers whole-house cooling too.


Air conditioner vs whole house fans:

While both an air conditioner and a whole house fan chill your home, they operate in quite different ways.

A window air conditioner, a portable air conditioner, or a ducted air conditioning system are all examples of air conditioners. To transmit heat from the interior air to the outside, all air conditioners utilize a chemical called Freon, which transforms from a gas to a liquid.

A ducted air conditioning system circulates the air within a residence, whereas a window air conditioner draws air in from the outside. As a result, while a central air conditioner may chill the air and lower humidity levels, it will not bring in fresh air from outside.

A whole-house fan, unlike an air conditioner, does not have Freon, a compressor, or a condenser. It’s simply just air, moving air.

To support an air conditioner, whole-house fans are often installed. That is, when the circumstances are favorable, it provides a more efficient means of cooling.


What is the best whole house fan for me:

It’s rather simple to figure out how big of a whole house fan you will need. Simply follow the three basic actions outlined below.

1. Size of your house:

Calculate your home’s square footage excluding the basement. To accommodate for this, raise the square footage figure if you have high ceilings. The estimates are based on an 8′ ceiling height. If your ceilings are 10 feet high, increase your square footage by 25%.

2. Multiply the size with 2:

By multiplying the square footage by two, you get the total area. This is the CFM of the fan that you’ll need to cool your area, and it’s what most people choose.

If your home is 2,000 square feet, for example, you’ll need a 4,000 CFM fan.

3. Vent Area:

Inspect the area around your attic vents. For every 750 CFM of fan, there should be at least 1 square foot of vent space. Simply put, ensure that the attic air vents can handle the volume of air that will be forced into the attic. If the overall vent area is insufficient, you (or your professional) should expand the roof vent area.

Returning to our example, a 4,000 CFM fan will require 5.3 square feet of vent space (4,000/750).


When buying for a whole house fan, seek for one that can deliver the required CFMs. If your home is large, you may need two systems to get the required air flow.

We also urge that you examine the degree of noise. While you’ll need to move a lot of air, no one wants a wind turbine hanging from their ceiling. These systems can be quiet; nonetheless, keep in mind to monitor the noise level.


Installing a whole house fan:

Before you start installing a new fan, make sure your home is well ventilated. If you don’t, you could have to replace or repair your complete fan system later. You should also make certain that there is enough light and fresh air in your home. As a result, it’s critical to think about the size and type of wood for your fan. Wood is typically a better option than plastic since plastic will deform over time.

Follow these safety precautions while installing attic fans:

1. Turn off the electricity at the main fuse box or circuit breaker. Make sure there is no electricity flowing through the cables.

2. Comply with all local laws. If you’re unsure about anything, consult a licensed electrician.

3. Follow the installation instructions provided by the manufacturer. Install the fan in the right area and make sure there is enough support and no blockages.
