Service whole-house fan
Why it matters
An uninsulated attic louver allows cold air to leak into the house in winter, negating heating efficiency. Debris jams the shutter and forces the motor to work harder.
Stop forgetting to do this.
Hearth generates a personalized maintenance schedule so you never miss another service whole-house fan.
