Frequently Asked Questions
How effective are whole house dehumidifiers?
Whole house dehumidifiers are highly effective at controlling humidity levels when properly sized and installed. They can reduce relative humidity to around 45-50% throughout an entire home, preventing mold, mildew, and musty odors. Advanced humidistat controls precisely regulate moisture levels.
Can a dehumidifier affect the whole house?
Yes, a whole house or central dehumidifier is designed to impact humidity levels in the entire home. Ducted systems work with the HVAC air handler to circulate dehumidified air through supply vents in all living spaces. This provides whole-home humidity control.
When should I run my whole house dehumidifier?
Most homeowners run their central dehumidifier continuously during humid summer months. You can also add a humidistat control to automatically activate the dehumidifier when humidity rises above a set point, around 50-55%. This maintains optimal moisture levels year-round.
