Answer:
Yes, mini-split lines can run through an attic, and in our experience, this is a common and effective way to route refrigerant lines when outdoor walls or other direct paths are unavailable. We think it’s a practical solution, provided the lines are properly insulated and protected to prevent potential issues.
More On “Can Mini Split Lines Run Through an Attic?”
Routing mini-split lines through an attic is a viable option for many homes. This method is often used when outdoor unit placement or wall access requires an alternative route. In our years of experience, we’ve seen homeowners benefit from this approach, especially when aesthetics and convenience are priorities.
However, proper insulation is critical to ensure the lines are protected from extreme temperatures in the attic. Without adequate insulation, the refrigerant lines may lose efficiency, affecting the system’s performance. We also recommend securing the lines to prevent any movement that could cause wear or damage over time.
Another consideration is condensation. Attics can be prone to moisture, so it’s essential to include a drain line to manage any condensation effectively. In our opinion, working with an experienced HVAC professional is key to ensuring the lines are installed correctly, following all building codes and manufacturer guidelines.
