Whole-house fans are a type of ventilation system that can be used to cool your home by exhausting hot air and bringing in cooler air from outside. These systems are installed in the attic and use a large fan to circulate air throughout the home. They are most effective when used in conjunction with other cooling strategies such as shading and natural ventilation.

Whole-house fans are typically more energy-efficient than traditional air conditioning systems, as they do not use refrigerants or compressors. They are also less expensive to install and operate, making them an appealing option for homeowners looking to save energy and money.

To get the most out of your whole-house fan, it’s important to properly size and install the unit. The size of the fan should be based on the size of your home and the local climate. It’s also important to ensure that the fan is properly vented to the outside, as this will help to exhaust hot air and bring in cooler air.

In addition to using a whole-house fan, there are several other steps you can take to cool your home efficiently. These include sealing and insulating your home, using energy-efficient windows and doors, and shading your home to block out the sun’s heat. You should also consider using a programmable thermostat to control the temperature in your home and reduce energy use when you’re not there.
