One multi-split offer lists two indoor units and a small outdoor unit.
THE LIVERPOOL FIELD GUIDE / AIR CONDITIONING
Air conditioning installers in Liverpool
A sunlit living room and a night-time bedroom call for different cooling briefs. Record glazing and occupancy for each Liverpool room.

START WITH THE PROPERTY
Give each room its own day
A Liverpool living room with afternoon sun and a bedroom used only overnight do not share the same load profile. List glazing, occupancy and desired temperatures separately instead of requesting 'air con for two rooms'.
BEFORE YOU ACCEPT A QUOTE
Compare comfort room by room
The proposal should explain capacity, indoor position and airflow for each room. If one outdoor unit serves both, ask what simultaneous operation means for performance and noise.
ILLUSTRATIVE QUOTE COMPARISON
Can the living room and bedroom cool at once?
Another states simultaneous capacity and the night-time sound at the bedroom.
Ask both firms for performance when both rooms call for cooling. Nominal room-unit ratings do not prove the combined outdoor system can meet that use.

Set expectations for simultaneous use.
If one outdoor unit serves a living room and bedroom, ask how performance changes when both call for cooling. Controls and sound at night deserve their own explanation.
