What Customers Are Saying

Customers overwhelmingly praise this line set cover for delivering a clean, professional finish that transforms mini-split installations. Most highlight how it hides unsightly copper lines and wiring, creating a polished appearance that rivals contractor work. Many find installation straightforward and intuitive, requiring no special tools. Reviewers confirm it effectively protects refrigerant lines from sun, rain, and weather exposure. Some note the 12-foot length falls short for standard 25-foot line sets, requiring additional purchases. A few report gaps between sections or color mismatches. Despite minor drawbacks, most consider it a worthwhile aesthetic and protective upgrade.

Looks great and protects the lines

We had one for about 3 years. It looked great. We had to remove it to reside our house and decided to buy another new one after siding was done. The hose wrapped inside still looked brand new.

Misleading. Not 5.5" it is 4.5"

Would Not Recommend

This model number is for a 4.5" wide kit. Mr. Cool apparently does not make 5.5" wide kits in tan.

A necessary add on

I bought this with the Mr Cool mini split installed last week. Quality better than expected. Trimmed out the otherwise unsightly lines nicely. Good fit and finish. Recommend.
