Types of Whole House Fans

Whole house fans are important tools for improving indoor air quality in your home and keeping it nice and cool when the weather outside is anything but. It is important, though, to make sure you are getting the right kind of whole house fans to meet the needs of your home and your climate.

There are essentially two main types of whole house fans.

1) Unvented Ceiling Mounted Whole House Fans

2) Ducted Whole House Fans

Beyond the two major types, there are other considerations to keep in mind as well, such as standard whole house fans, inline whole house fans, and whole house fans with insulated doors.

People who have a good mix of winter and summer weather, for instance, might be more interested in insulated door whole house fans that provide some degree of defense against colder air creeping into your home during the long, cold winter months.

Ceiling Mounted Whole House Fans

These fans are mounted on the ceiling in the space between the attic and your living area. These fans are popular with homeowners as a result of their lower costs and relative ease of installation. The one downside for some homeowners, though, is that these fans do produce more noise than ducted fans, the tradeoff is that the right-sized ceiling mounted fan moves a lot more air.

There are considerations to keep in mind, however, when installing and using ceiling mounted whole house fans.

Choose the location wisely. You do not want to install the fan in a location where the air will not circulate properly throughout the house.

Watch out for potential energy losses. It is easy for air to escape through the whole used to install the whole house fan, mitigate that by buying a vented door unit or investing in a cover you can install over your fan during winter months.

Size does matter when it comes to ceiling mounted whole house fans. If you get one that’s too small for your home, it won’t accomplish the goal you have for it. If it’s too large, you may experience other problems. The ideal size for your fan is one that will remove a certain amount of cubic feet of air per minute (CFM). To determine this value, you divide the total cubic feet of your home by three or four. For efficient cooling, a 2,000 sq. ft. home would need a fan rating of (3,000 – 4,000 cfm).

Ducted Whole House Fans

Unless, of course, you are interested in a quieter fan. In that case, you’ll want to know more about ducted whole house fans. Ducted fans are quieter than ceiling mounted varieties and they expel heat from many locations.

The final choice comes down to a matter of preference, if not price for most people. Both types of whole house fans, though, are better than living without one. Keep in mind, QuietCool fans are designed to quietly cool your home, regardless of model.
