12-YEAR LIMITED WARRANTY If the System is installed in a residential single-family home and registered by a Ductless Pro within 90 days from installation, the parts and compressor will be warranted for a period of 12 years, to the original owner, so long as the original owner resides in the home. So all the same legalities mentioned in the standard warranty apply, but you can receive 12-years of parts coverage.
