What should be recommended if a customer complains that their walls and windows are wet after installing a Direct Vent Radiant Heating System?

Recommending the installation of a Mechanical Ventilation System addresses the issue of excess moisture accumulation in the home after installing a Direct Vent Radiant Heating System. This situation often arises from inadequate ventilation, leading to humidity levels rising, which can manifest as wet walls and windows.

A Mechanical Ventilation System helps to actively manage airflow within the home, replacing stale, humid indoor air with fresh, dry outdoor air. This not only reduces moisture levels but also improves air quality, which is essential for maintaining a comfortable and healthy living environment.

While other options may seem applicable, they do not directly resolve the underlying issue of insufficient ventilation. A dehumidifier can help remove moisture, but it does not prevent additional humidity from entering the space due to poor ventilation. Sealing windows and doors can trap moisture inside, potentially worsening the situation. Increasing the indoor temperature might provide temporary relief but could further increase humidity if ventilation is not addressed. Therefore, implementing a Mechanical Ventilation System is the most effective solution to ensure proper air exchange and moisture control in the home.
