Do I need an ERV or an HRV?

Both recover most of the energy from the stale air they exhaust while bringing in filtered fresh air. The difference is moisture: an ERV transfers humidity as well as heat (the right choice in humid Texas and Florida), while an HRV moves heat only (better for cold, dry winters). A tight, stuffy, or newly-sealed home is the main candidate.

How is the right ventilation size determined?

Sizing follows the ASHRAE 62.2 residential ventilation standard, which sets the fresh-air rate from the home's floor area and bedroom count. A good installer calculates that rate rather than guessing — an undersized unit won't clear stale air and an oversized one wastes energy.

When is the busiest season for Green Bay IAQ companies, and how does it affect scheduling?

Demand rises during humid summers and just before winter sealing work, which can delay scheduling. Book dehumidifier and ventilation installs early in spring to avoid summer backlogs. For winter preparations, schedule ventilation and humidifier checks in autumn. Flexible scheduling and early booking reduce wait times during peak months.

What ventilation upgrades reduce mold risk in Green Bay's humid summers?

Balanced ventilation with ERV or HRV systems and targeted exhaust in damp areas reduces indoor humidity and mold risk. Ensure installers measure baseline moisture and design for continuous or demand-controlled ventilation. Proper insulation and duct sealing alongside ventilation are essential to prevent condensation in duct runs and building cavities.

Which IAQ systems in Green Bay typically require a licensed HVAC crew to install?

Major equipment such as whole-house dehumidifiers, ducted ERV/HRV systems, and furnace-integrated humidifiers usually require licensed HVAC professionals. These systems tie into ductwork and electrical systems, and correct sizing matters for performance. Look for installers who document load calculations and provide manufacturer warranty registration.

Google rating. A strong rating floor reflects whether the install actually fixed stuffiness/odors.
