Frequently asked questions
Helpful information about multi-room air conditioning
Can one outdoor unit serve several rooms?
Yes, a suitable multi-split outdoor unit can serve multiple compatible indoor units. Capacity, pipe lengths and manufacturer limits must be checked.
Can each room have a different temperature?
Each indoor unit normally has its own controller, allowing individual room settings within the system’s operating mode and design limits.
Is multi-split always the best option?
Not always. Available space, pipe routes, capacity, efficiency, redundancy and cost are considered before ARC AIR recommends an arrangement.
