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.

The previous Mitsubishi air conditioner had a good run at 20+ years old. We replaced it with a new Fujitsu unit which is physically smaller and quieter unit plus being a lot more efficient. The customer was elderly and it was important to have a wall control that is very simple to use. We set it up so everything is on automatic and he only had to press the on/off button.
