What is the difference between an ERV and an HRV?

An ERV transfers both heat and moisture, which helps manage humidity in warmer climates. An HRV transfers heat only and is typically better for colder, drier climates.

Do I need mechanical ventilation in a new home?

Many codes and best practices recommend or require mechanical ventilation in tight, energy-efficient homes to provide consistent fresh air and control indoor pollutants and moisture.

When should I use a whole-house dehumidifier?

Use a whole-house dehumidifier when indoor humidity stays high, especially in humid climates or homes with limited natural ventilation. It provides consistent humidity control through the duct system.

Are bathroom exhaust fans enough to control humidity?

Exhaust fans remove localized moisture from bathrooms, but whole-home humidity issues may require balanced ventilation (ERV/HRV) or a whole-house dehumidifier depending on climate and building tightness.

Ventilation & Fresh Air

Modern homes and light-commercial spaces are built tighter than ever. Without controlled ventilation, pollutants and moisture can build up, leading to odors, comfort complaints, and long-term damage. This category covers the equipment that brings in fresh air, exhausts stale air, and manages humidity for healthier indoor air and better system performance.

Shop bathroom exhaust fans, ERVs and HRVs for balanced ventilation, plus whole-house dehumidifiers and comfort-focused humidifiers/dehumidifiers. Choose the right solution based on climate, square footage, occupancy, and whether your goal is code compliance, odor control, humidity reduction, or full IAQ improvement.

ERVs are often preferred in humid climates because they transfer both heat and moisture. HRVs transfer heat only and are commonly used in colder, drier regions. Exhaust fans remove localized moisture at the source, and whole-house dehumidifiers provide stable humidity control through the duct system.

Pro tip: If you’re fighting humidity, fix ventilation and drainage first. Dehumidifiers work best when the house has controlled fresh-air intake and proper exhaust at kitchens/baths.
