What condition may be prevented by fixing leaks in HVAC units?

Fixing leaks in HVAC units plays a crucial role in preventing moisture entry from crawlspaces. When HVAC systems are not properly sealed, they can create pressure imbalances that lead to moisture being drawn into the system. This moisture can then enter crawlspaces, which can contribute to various issues such as mold growth, wood rot, and damage to insulation. By addressing leaks, you enhance the integrity of the building’s envelope and help ensure that exterior moisture is kept at bay, promoting a healthier indoor environment and reducing potential moisture-related problems.

While increased energy consumption is a concern linked to leaks, fixing them primarily aims to maintain a balanced and controlled environment, which is more directly related to moisture management. Similarly, thermal bridging and unauthorized access are not directly associated with the function of HVAC systems and would not be issues primarily resolved through sealing HVAC leaks. Thus, the focus remains on preventing moisture penetration, making moisture entry from crawlspaces the most relevant condition addressed by fixing these leaks.
