The MRCOOL® DIY® 5th Gen Line Set is designed to connect compatible MRCOOL DIY indoor air handlers to their outdoor condensers. Using pre-charged R-454B refrigerant and Quick Connect® fittings, it provides a simplified installation solution for MRCOOL DIY single-zone, multi-zone, and central ducted systems.
Available in multiple line set sizes and lengths, this system makes it easier to select the correct connection based on the air handler capacity and installation distance. The kink-resistant construction is designed for easier routing while the UV-protective insulation sleeve helps protect the line set from outdoor exposure.
The No-Vac design eliminates the need for cutting, brazing, vacuuming, or refrigerant charging during a standard installation. Depending on the configuration, multiple line sets can also be combined with a compatible coupler to achieve up to 75 feet of total length.
