Buying Guide For The Best Whole House Fan

Whole house fans help to suck out heated air from the house and at the same time force it through the attic, to deliver a cooler outside air. They help to remove hot air and consume less energy than the traditional ones. We have the following guide that focuses on the top features to look out for before buying a fan.

Quality Shutters

The shutters must be of good quality to reduce thumbing and vibrations in your house. Look for an energy-saving unit with self-sealing shutters that close automatically when the fan is idle to help prevent heat escaping when not in use.

Timer Control

Some house fans come with a timer control which is recommended over the use of a thermostat. The main reason is that the thermostat turns the unit on when no doors or windows are open. Also, a lit fireplace can trigger it to go on as if the thermostat controls it.


Most fans for the whole house have compact dimensions as low as 24 inches. Go for a larger size that runs s efficiently at the lowest speed, to use less energy. A heavier one usually is quieter than the lightweight models because of its foam weatherstripping elements held down only my own weight.

Installation Method

Another thing to consider is the installation method and its simplicity. Most fans don’t require special tools to assemble and are quite easy to complete within minutes. When it comes to the Direct-drive designs, they allow a DIY setup because of the lack of cutting attic joists. Note that the Belt-drive fans that use a pulley system take longer to assemble, although they deliver quieter and smoother operation.

Size of Your House

The bigger the space, the bigger the fan should be. If you use a compact size, it will not work efficiently to produce cold air within the whole house. The old and newer fan models are rated according to the CFM, which means cubic feet per minute of air they move. Pick a large one to move air quickly and effectively. Also, consider the size of the ceiling. For instance, if your house has an 8-foot-high ceiling, multiply the overall square foot by 3 to get the correct fan size.

Attic Vents

Lastly, check the vents. There are different types, including roof louvers, gable vents, eave vents, intake vents, and soffit vents. Note the location and size of each to get a correct estimation of your attic’s square footage. Do not underestimate your ventilation needs.


Picking the best whole house fans should be more comfortable after going through this review. You will find the top products that deliver excellent service. Some of the benefits include eliminating stale and unhealthy air, prevents mold and moisture, and also leaves your house clean and refreshed. Make the atmosphere more breathable in your home by picking one of the products on the list to enhance comfort and maximum relaxation in all seasons.
