As the name suggests, a whole house fan can greatly reduce the temperature in an entire house. However, the model and make of the fan must be suitable for the house and its size to be effective.
A whole house fan is installed in the ceiling of the upper level of a house, so that it is connected to the attic. A central location, air-tight installation, and good ventilation are all crucial to the successful operation of this appliance. The following are several advantages to using a whole house fan in your home.
1. Fast Operation
These fans work by drawing hot air from the house into the attic and then outside via ridge or gable vents. The empty space left by the hot air is filled with cool, fresh air from outside the house. Compared to a central air conditioner, a whole house fan works much faster, and you begin to feel the cooling effects in minutes. However, a whole house fan will obviously only work if the external air is cooler than the air indoors.
2. High Energy Efficiency
A whole house fan is a much more environmentally-friendly option than central air systems or room AC units.
3. Low Operating Costs
During operation, a whole house fan costs about 10–25% of the money an air conditioner costs to run. It is far cheaper, and you can save hundreds of dollars in your electric bill every summer.
4. Easy Installation
Installing a whole house fan is easy and uncomplicated. Most whole house fans are built to accommodate roof trusses and attic joists, so it can actually be a do-it-yourself project, with minimal assistance from another person.
5. Low Cost of the Appliance Itself
A whole house fan generally costs half as much as a window air conditioner. It can be 10 times cheaper than a central air conditioning unit, not to mention the cost of the ductwork and installation. If you do not have extreme summer weather, this appliance can replace your AC entirely.
6. Removal of Stale Indoor Air
Because a whole house fan draws in hot air to the attic and then lets it out of the house, your indoor air is considerably fresher. This helps remove and prevent odors and provides excellent ventilation all around the house.
7. Quiet Operation
Newer models of whole house fans operate fairly quietly, and do not emit the loud, disturbing noises associated with large fans. You can operate a whole house fan throughout the night and enjoy a good night’s sleep even if you’re a light sleeper.
8. Reduced Need for Air Conditioning
When you use a whole house fan, the entire house can be effectively cooled down by drawing in air from the outside. When operated during summer mornings, evenings, or nights, there is usually no need for other air conditioning. In fact, you should not use an AC at the same time as a whole house fan, because the cool air from the air conditioner will be let out of the house and replaced by air from outside.
