Whole-house dehumidifiers remove excess moisture throughout your home giving your home a more comfortable feel without having to rely on your HVAC system to remove all the humidity.

The Model 1750 also features automatic control, so there’s never a need to manually control the dehumidifier–just set it once and forget it! It is installed directly into your new or existing heating and cooling system.
