MRCOOL's DIY Advantage: Empowering Homeowners

What truly sets MRCOOL apart is its commitment to providing a genuinely do-it-yourself experience with its mini splits. The DIY design revolutionizes the installation process, eliminating the need for professional HVAC technicians and reducing associated costs. MRCOOL achieves this through several patented innovations:

1. Precharged Line Sets: MRCOOL's mini splits utilize R-410a pre-charged Quick Connect line sets, allowing non-professionals to install the system without requiring specialized tools, equipment, or training. These line sets simplify the installation process significantly. Without them, connecting, vacuuming, and charging the line set would necessitate expensive HVAC tools, making the installation considerably more expensive. To ensure reliability, the line sets undergo rigorous hydrostatic pressure testing conducted by independent product testing companies, subjecting the connected fitting assemblies to a minimum pressure of 400 PSI in an environmental chamber for eight hours. Additionally, a pull test of 500 pounds of force is performed to ensure the durability and strength of the line sets.

This armored cable is shielded in coated flexible conduit, providing higher mechanical protection and durability. It comes equipped with flexible easy connectors for seamless and trouble-free coupling, further simplifying the installation process.

3. Coupler Kits: MRCOOL also offers coupler kits for situations where the included 25 ft line sets may not be long enough to accommodate specific installation needs. These coupler kits come in two sizes: one for 9,000, 12,000, and 18,000 BTU units, and another for 24,000, 36,000, and 48,000 BTU units. The coupler kits provide a convenient solution for extending the line sets, ensuring flexibility and adaptability in various installation scenarios.
