Attic fans get mixed reviews, and the truth is that they help in some Oklahoma City homes and hurt in others. A powered attic fan pulls hot air out of the attic, but it also pulls replacement air from somewhere. If the ceiling is leaky, some of that air comes from inside your air-conditioned house.
That is why we always check the attic before installing a fan. If the soffit intake vents are clear and the ceiling is air sealed, a roof or gable fan or a solar attic fan can lower attic temperatures on summer afternoons. If the ceiling is leaky, we seal it first or recommend better passive ventilation instead.
We also install whole-house fans, a different tool that pulls cool evening air through open windows and exhausts it through the attic. In the spring and fall, when Oklahoma nights cool off, a whole-house fan can let you skip the AC on many evenings.
Oklahoma City tip
A powered attic fan should never be installed in an attic with spray foam on the roof deck. That attic is designed to be sealed. Fans belong in vented attics only.
When an Attic Fan Can Help
- ✓A vented attic with clear soffit intake
- ✓An air sealed ceiling with no major leaks
- ✓Very hot attic on summer afternoons
- ✓Not enough roof vents for the attic size
- ✓Mild spring and fall evenings you want to use (whole-house fan)
- ✓A failed or noisy existing attic fan
Powered, Solar or Whole-House: Which Fan Fits
Powered roof and gable fans move the most air and can be set with a thermostat and humidistat. Solar attic fans cost nothing to run and work hardest on sunny afternoons, but move less air on cloudy days.
Whole-house fans are not attic ventilators. They cool the house itself on mild evenings, which suits Oklahoma's spring and fall. If your real goal is lower bills, insulation and air sealing usually come first, and we will say so.
