Installation and Maintenance
I consider the installation process when selecting a line set. A 50-foot length is generally manageable, but I always ensure I have the necessary tools and expertise for a proper installation. Additionally, I think about maintenance; a line set that is easy to access for inspections and repairs is a definite plus.
