Homeowner Tips

Keep the exhaust fan clean to ensure adequate ventilation. Use a vacuum or duster to regularly clean the fan and inside the housing.

Consider replacing an old and noisy bathroom fan with a new quieter and more energy efficient model at the time of this work. Look for a fan that is Energy Star® qualified with a noise level of less than 1.0 sone.
