A whole house fan is a fan that is installed in your attic and provides ventilation to your entire home. It acts as a complement or a substitute for your air conditioning system, and can help keep your home cool during the summer months. There are a number of benefits associated with a whole house fan, and understanding them can help you decide if a whole house fan fits your home's needs.
Reduced Energy Bills
Whole house fans are installed in the attic, and will pump the hot air that rises from within your home to the outside. The hot air is replaced with cooler air from the exterior, gradually bringing down the temperature of your home. This can save you money in the long run, as a whole house fan uses less energy than a central air conditioner, reducing your overall energy bill at the same time as reducing your carbon footprint.
Improved Air Quality
A whole house fan constantly pumps air out of your home, while drawing in air at the same time. This will improve overall air quality, as the air from the outside will pass through the whole house fan's filter, removing dust and other allergens in the process. Furthermore, the constant movement of air from the interior of your house to the exterior can remove odors from throughout your home, keeping every room smelling fresh.
Whole house fans are fairly quiet when they operate, especially when compared to central air conditioning units. Additionally, as they are installed in the attic and do not make use of ductwork, their noise will be largely contained within the attic. This means that you most likely will not hear when the fan kicks in, and you won't be woken up in the middle of the night due to a noisy operation, as can happen with a central air conditioner.
Ease of Installation
Whole house fans are extremely easy to install. Those with some sort of construction knowledge could even complete the project themselves--though this is not recommended, as professional installation ensures the proper operation and safety of a whole house fan. However, even with professional installation (from professionals such as Affordable Comfort Heating and Cooling), the ease of installation of a whole house fan still carries benefits. Since whole house fans can be installed so easily, the process goes by fairly quickly, saving you money in terms of labor costs, especially when compared to the more complex installation process associated with an air conditioning system.
