• Volatile organic compound (VOC) off-gassing diminishes, improving overall IAQ
• Houseplants maintain healthier transpiration rates without developing moldy soil surfaces

The Science Behind Dehumidification

Psychrometrics in Everyday Terms

By lowering the dew point of indoor air, a dehumidifier forces water vapor to condense on its cold coils, expelling dry air back into living spaces. The process removes latent heat, making rooms feel cooler without lowering thermostat settings.

Latent vs. Sensible Heat

• Latent heat: Energy stored in water vapor; removed by the dehumidifier
• Sensible heat: Temperature you feel; primarily managed by heating or cooling systems

Balancing latent and sensible loads through proper dehumidifier sizing keeps HVAC units from short-cycling or over-working.

Addressing Humidity in Renovations and Additions

Home Theater Build-Outs

Soundproofing materials such as acoustic foam can trap moisture. HEP recommends an auxiliary return vent linked to the primary dehumidifier.

Sunroom Conversions

Large glass areas amplify condensation risk. Integrating a dedicated supply register from the dehumidifier curtails moisture accumulation on frames and sills.

Finished Attic Spaces

Expanded living areas near the roofline require careful duct routing through tight cavities. Low-profile dehumidifier models fit between rafters, preserving headroom.

Preventing Future Moisture Intrusion

Exterior Measures

• Redirect downspouts at least six feet from foundations
• Maintain proper soil grading away from basement walls
• Seal exterior penetrations around utilities and hose bibs
