Review: Lineset - Owner very helpful - Good price. The owner of the company was very helpful to explain that this would work for installing a new central air unit. The draw back is that he couldn't offer over night shipping.
Review: Good bang for the buck. - Wish it came in a shorter roll but was everything i needed in 1 package. Well packaged when shipped and arrived quickly for the install we had scheduled. Bent very nicely with the tubing bender and the insulation is good quality.
