Reasons to Install a Whole-House Fan

What is a whole-house fan? It is a large fan installed into a home that draws air through open windows and then exhausts it out the attic and roof. A whole-house fan requires professional installation, since it must be appropriately sized in cubic feet per minute of cooling power to match the volume of space in the building.

If you are interested in having a whole-house fan put in, call HVAC professionals to measure your home’s volume and then handle the wiring work to install the right sized fan. If necessary, the professionals will also put in new attic vents.

How does a whole-house fan benefit me?

A whole-house fan will help keep your home cooled down during times when the outside temperature is lower than the inside temperature. As the fan draws in outside air and pulls it up through the attic, it generates powerful ventilation throughout the rooms and replaces the hot air with cooler outdoor air. A whole-house fan creates 30 to 60 air changes per hour.

During many parts of the year, a whole-house fan is often sufficient to keep a home comfortable without needing to turn on the air conditioning system. Since whole-house fans use, on average, only a tenth of the electrical power of air conditioning systems, they will help save an immense amount on a household’s cooling costs.

Even during hot weather, a whole-house fan can provide a remarkable level of comfort if used correctly: you can turn the fan on during the cool of the early morning, then seal all the windows to keep out the heat during the rest of the day. In the evening, you can turn the fan back on to draw in the cooler nighttime air.

A whole-house fan will also help increase indoor air quality: the ventilation from outside removes the stale and contaminant-filled air inside, giving you a more pleasant home environment.
