Our Quick Connect® line sets are one of the most important components of our DIY® Ductless Mini-Split Systems, because they’re what makes the system do-it-yourself. Without these line sets, you would need to hire an HVAC technician to route, connect, braze, and charge the line set, which makes getting a new HVAC system much more expensive than just the initial purchase. Throughout our initial development and continued use of these DIY® Quick Connect line sets, these line sets have proven to be extremely reliable. They have even earned a patent for their significance, ease of use, and importance in the MRCOOL® DIY® Ductless Mini-Split’s installation.
 
Because our Quick Connect® pre-charged line set connections are unique within the industry, 360º Product Testing performed a series of quality assurance tests to evaluate and ensure their resistance to leaks. 360º Product Testing has worked with corporations and organizations like the Department of Homeland Security, LG, PepsiCo, and the U.S. Air Force, Army, and Navy, meaning they are a highly-trusted resource for product testing. Through this product testing session, we can be sure that we are consistently providing products of the highest quality to ensure your best comfort experience.
