Looking at the RKM50ZVMG for your home?
This is the outdoor half of a pair. The indoor unit is the half you live with, and it should be named before anything is agreed.
What to pin down before you commit
- The paired indoor model number — the unit that mounts in the room
- Whether the capacity suits that room, and how that was decided
- What happens to the existing piping, drainage and bracket
- Whether the old unit is being removed and disposed of
