Home Ductless System FAQs
Can I install my own ductless system?
There are manufacturers and others on the internet who over-simplify the installation of a ductless system. If the system is sold with pre-charged, quick connect refrigerant tubing, it is possible however since cutting the tubing to length is not possible the end result will not look like their pictures. In addition, these connections do not last as long as mechanically flared connections and if there is a problem with the O-ring seal at the time of installation you have a real mess on your hands. The labor warranty for any problems encountered at the time of installation and the first year is usually covered by the installing contractor, so if that’s you, you may be dealing with something totally beyond your ability.

Over the life of the system this savings can exceed the original expense.
