Share 'Technical question about mini split heat pump line set maximum length'
I'm installing a two-zone Mitsubishi mini split (in Pasadena, CA area, 1400 sf, single family detached, one-story home, if context is relevant). This is my first install, and I am trying to determine if extra refrigerant needs to be added based on the line set distance to each of the two indoor units. The outdoor unit is factory charged with R410A.
