Frequently-Asked Questions

Do I need to vacuum this lineset before use?
No. This lineset is pre-charged and factory-sealed, so vacuuming is not necessary.

Is it compatible with other brands besides MRCOOL?
This lineset is specifically designed for MRCOOL systems and may not be compatible with other manufacturers’ units.

Can it be reused on another system?
Reusing No-Vac linesets is not recommended, as the refrigerant charge may not be adequate after disconnection.
