Whole House Fan for New Construction

If your home has recently had construction or construction is still ongoing, you may be wondering how to ventilate the space.

When sawdust, dust, and fumes from construction buildup it can leave a lingering smell for new construction and leak into other parts of the home if proper ventilation isn’t carried out. In this way, ventilating new construction benefits workers and homeowners — neither of them has to endure poor air pollution, bad smells, or high temperatures.

How Does a Whole House Fan Work?
Whole house fans are much more effective and powerful than your everyday house fan. They exhaust trapped indoor air and replace it with fresh outdoor air through open doors and windows.

Benefits of Whole House Fans for New Construction
Whole house fans offer an effective ventilation solution, eliminating the following problems: 

  • Air pollution: Air pollution is an often inevitable result of construction. Sawdust, concrete dust, and other particulate matter can hang in the air and cover the surfaces of the new construction, even if the construction team sweeps the floor and cleans up afterward.

Furthermore, if there’s little ventilation inside the construction site, then fumes created from gas-powered equipment and generators can create indoor air pollution which can hang in the air and create a bad smell.

  • Heat: New construction doesn’t have to be unpleasant. If the new space is fully sealed, it’s sure to heat up in the summer sun. Using a whole house fan or garage exhaust fan is a good way to cool the space down and increase comfort without using as much energy as an air conditioner.
  • Damage: The last thing you want for your new construction is any damage to happen to it. Unventilated new construction spaces are particularly prone to moisture damage. Mold, mildew, and rot can set in if moisture and humidity are allowed to accumulate over time.
