Before we get into figuring out the best small whole house fan for your home, let’s get a couple questions out of the way.
How do Whole House Fans Work?
When you think of a whole house fan, the design of it is actually pretty simple. The attic mounted fan pushes through the hot air through attic vents, while it brings in cooler, outside air through doors and windows that are open. Not only does this quick air exchange remove any built up heat in your house, but it also makes the house that much cooler with a nice breeze that will travel through your home.
Are Whole House Fans Better than Air Conditioning?
For the longest time fans have been replaced with air conditioning units but fans are now finally making a comeback. Why? Mostly because when it comes to energy efficiency and cost, they are much better than an air conditioning unit.
Also, the latest models of whole house fans have self-sealing insulated shutters that close when the fan isn’t on. This makes it harder for any heat to leave through the fan even when you are not using it. This key feature is what makes fans much more cost effective to use than air conditioning. Whole house fans are more efficient and cheaper than air conditioning in the long run.

Factors You Should Consider When Buying a Whole House Fan
Do You Want Moderate Flow and Efficient Cooling?
Then choose 1.5 to 2.0 CFM of air flow per square feet of living space.
Cooling your home will take a lot longer using this option. The greatest benefit from an efficiency standpoint happens within the first few air exchanges in the living area of the room. After all that happens, the cooling effect is lowered. However, a constant flow of air is usually required to make sure that the heat radiating in your walls, rooms, ceilings, and attic is removed.
Or Do You Want the Breeze Effect?
You should choose 2.5 to 3.0 CFM of air flow per square feet of living space.
This is the most commonly used air flow rate. A lot of people like to feel the breeze effect that whole house fans can create. It is probably the biggest reason why people choose whole house fans. When the air moves across your body, it will have an evaporative effect on your sweat. This means your skin will feel a lot cooler than it actually is.
Sizing your whole house at this rate will allow you to feel the most cool and relaxed. It will also help make the temperature in your house go down the quickest.
Do You Have Cathedral Ceilings?
If you live in a space with high ceilings, all that does is increase the total cubic feet of air space. What that means is you have more air that you need to fill up when you turn on your whole house fan. You will definitely want to take that into consideration when you go out and start shopping for the right whole house fan for you.
If you have a large house with large ceilings, most experts believe it would be wise for you to size up. That way you can actually feel your fan working. You do not want to spend money on a whole house fan and not be able to reap the benefits.
Is Your Home Built Ranch Style or Oddly Shaped?
The type of home you are living in plays a major role in what kind of whole house fan you should target. If your home has a centrally located system, and you live in a ranch style home, you may not need a huge whole house fan. But if your house is unusually shaped or large, it would probably best for you to go out and get a decent sized unit.
Again, you want to make sure that your air is evenly dispersed. You do not want to walk in one room, feel a nice breeze and be comfortable, but then walk in another and feel the heat and start to sweat. You are just asking for trouble if that happens!
Do You Have Enough Existing Ventilation to Accommodate Air Flow off the Fan?
Before you buy your whole house fan, you want to make sure that you have enough roof venting to allow the air being pulled into your attic by the whole house fan to have the ability to escape out. In the end, it is all about balance when it comes to these things. What air comes in, must come out!
