Answer:
Yes, mini-split lines can run upward, and in our experience, this is a common routing method for reaching higher floors or attics. We think it’s a practical and efficient solution, as long as the lines are properly secured and insulated to ensure optimal system performance.
More On “Can Mini Split Lines Run Up?”
Running mini-split refrigerant lines upward is a standard practice when the indoor and outdoor units are located on different levels of a home. In our years of installing these systems, we’ve found that vertical routing is particularly useful for multi-story homes or when outdoor units are placed on the ground while indoor units are on upper floors.
To prevent inefficiencies, it’s crucial to ensure the refrigerant lines are correctly insulated. Without proper insulation, heat transfer may occur, reducing the efficiency of the mini-split system. Additionally, securing the lines in protective conduits not only enhances their durability but also provides a clean, professional appearance.
One aspect to consider is the drain line for condensation, which also needs to run upward in some cases. In our opinion, a condensate pump is a reliable solution to manage this, ensuring that moisture is safely transported away from the system. With the right planning and professional installation, running mini-split lines upward is a straightforward and effective way to optimize your HVAC setup.
