Recently had a commercial building with small offices internally approach me to swap out a Samsung split system which had failed due to being short on gas. We swapped it out with a Mitsubishi Electric split which was more efficient and quieter. Outdoor unit located on the roof out of the way of the carpark so it was no where to be seen. Having no gas in an older unit is a tough one due to gas prices fluctuating and the older gas is becoming more expensive due to it being phased out. Repair is always an option but due to the age and cost involved in repairing a 3.5kw unit, the better option was to swap it out and not have anymore problems arise.

We had an issue with the older Actron Air ducted air conditioner where multiple parts were failing and pricing to repair would outweight the cost of a new unit. The new Fujitsu unit was physically half the size of the Actron which allowed a lot more space. The control system installed was an Advantage Air Ezone tablet which allows full control from your phone/tablet via wifi and percentage control of airflow per zone. This gives greater control of temperature between rooms
