CONTROL HUMIDITY

Basement Dehumidification in New Hampshire
Basements are especially susceptible to high humidity. Cool basement surfaces combined with warm, humid summer air can create uncomfortable conditions and contribute to condensation and musty odors. Even when there isn't standing water, elevated relative humidity can become a persistent problem. A properly sized basement dehumidifier can automatically maintain the desired humidity level and discharge collected condensate directly to an appropriate drain. For larger or divided basements, we can design a ducted dehumidification system to provide better circulation between rooms rather than relying on a single portable unit in one location.
Whole-Home Dehumidifier Options
There isn't one dehumidifier installation that's right for every home. Capitol Comfort Heating & Cooling can install several different configurations depending on the application.
Standalone Basement Dehumidifiers
A high-capacity standalone dehumidifier can be an excellent solution for basements, crawl spaces, storage areas, and other spaces with persistent moisture.
Unlike a small portable unit, professional-grade dehumidifiers are designed for higher-capacity moisture removal and can be installed with a permanent condensate drain or condensate pump, eliminating the need to continuously empty a water bucket.
Ducted Dehumidifier Systems
For better air distribution, a dehumidifier can be installed with dedicated ductwork.
Depending on the home and system design, we can install return and supply grilles or multiple duct branches to pull humid air from different areas and distribute dry, filtered air throughout the conditioned space.
This can be particularly useful for finished basements, homes with multiple rooms, and applications where humidity isn't isolated to one location.
Whole-Home HVAC Dehumidifiers
A whole-home dehumidifier may also be integrated with an existing forced-air HVAC system when appropriate.
This allows the dehumidifier to work alongside your heating and cooling equipment to control indoor relative humidity independently of the thermostat temperature.
Your air conditioner naturally removes some moisture while cooling, but during mild or especially humid weather, the home may need dehumidification even when there isn't enough cooling demand to run the air conditioner.
A dedicated dehumidifier addresses the humidity itself, rather than overcooling the house just to remove moisture.
Ventilating Whole-Home Dehumidifiers
For homes that need both humidity control and controlled outdoor ventilation, we can also offer ventilating dehumidification systems.
These systems can introduce a measured amount of outdoor air while actively removing moisture and filtering the air before distributing it throughout the home.
This can be an excellent option for newer or tighter homes where controlled ventilation is desired but New Hampshire's humid summer air also needs to be managed.
A ventilating dehumidifier is different from an ERV. An ERV transfers heat and moisture between incoming and outgoing air streams, while a ventilating dehumidifier actively removes moisture using a refrigeration system.
