What is the Mitsubishi warranty?
All parts are warranted for a period of five (5) years to the original registered end-user with proof of proper installation. The compressor is warranted for a period of seven (7) years to the original registered end-user with proof of proper installation. Ten (10) year parts and ten (10) year compressor coverage is offered when your system is installed by a licensed contractor and registered with Mitsubishi in 90 days from the date of installation. Twelve (12) year parts and twelve (12) year compressor coverage is offered when your system is installed by a Diamond Contractor and registered within 90 days of installation. This is by far the best warranty currently in the industry offered by a ductless mini split manufacturer, but it’s important to note that as with all ductless mini split warranties in the industry, labor costs are not covered under the manufacturer’s warranty – extended warranties can be offered to cover that additional expense.
