Mini Split AC System Question

If the package deal says it's pre-charged with R410 and they give you 15 feet of piping and you need closer to 25 feet. Will I have to have a tech come in and put more refrigerant in because of the extended length of the piping?

No tech needed if you buy 25' pre-charged lines to a pre-charged system (inside and outside units both must be pre-charged). If not pre-charged you will need a tech anyway to properly pump down the system in addition to adding extra refrigerant.

Get a copy of the installation instructions and it should all be there.
