Many homeowners are quite confused about the difference between whole-house fans and attic fans. While both systems can be installed in the attic and can keep the temperature down in your home, they vary in operation. Whole-house fans can remove the hot air out through the vents and draw cool air through the windows. Meanwhile, attic fans force hot air out of the attic. Thus, whole-house fans are more efficient for your home.
Here's everything you need to know about how whole-house fans work and how effective they are:
Amazing ventilation and a cooling system
A whole-house fan is designed to work as an exhaust system that pulls hot air or the trapped heat out from a house or a building through the gables and vents by creating positive pressure. At the same time, it works as a huge fan that draws cool air to your home. This happens when the negative pressure and the fan draw the outdoor air through the window.
Take note that the windows must be opened when using whole-house fans. And for them to work most effectively, turn them on during the morning and evening when the outdoor air is cooler.
An affordable and more efficient alternative to air conditioner
Air conditioners are one of the common solutions to cooling your home. Not only are they expensive to buy—but they are also expensive to run. Your electricity bill spikes up more rapidly during the summer when the temperature is very high, and the AC units have to work double to provide cooling. This is why a whole-house fan is a more practical option. It can substantially and rapidly lower the temperature in your home while consuming 30% less than the electricity that AC units need.
Environment-friendly
Whole-house fans have lower operational costs and are much more environment-friendly compared to an AC. Aside from the fact that it doesn't require too much energy, it also doesn't need chemicals of any kind. Also, newer models from reliable brands are quieter, so you never have to worry about noise pollution.
