Why Whole-Home Dehumidifiers Are High Demand in Houston

Outdoor humidity in Houston regularly tops 80 percent. When indoor humidity exceeds 60 percent, dust mites multiply rapidly and toxic mold spores begin colonizing drywall, furniture, and clothing. A whole-home dehumidifier pulls gallons of moisture from the air daily, allowing you to set your thermostat at 76 degrees while enjoying the crisp comfort of 72 degrees.

Frequently Asked Questions

Whole-home dehumidifiers are typically installed in the attic alongside your primary air handler or in a mechanical closet. The unit ties into your central ductwork to distribute dry, filtered air throughout your entire home.

Yes. Dry air feels significantly cooler than humid air at the exact same temperature. Setting your thermostat 3 to 4 degrees higher while running a high-efficiency dehumidifier lowers overall summer electricity consumption.
