Kool Air removed an ageing cassette unit and installed a new 14kW Daikin premium inverter cassette system at Traralgon’s local Subway restaurant. The job required a crane lift to position the outdoor unit onto the rooftop, and the full installation was completed with the professionalism and attention to detail that Gippsland businesses have come to expect from the Kool Air team.
Project Details
- System installed: 14kW Daikin Premium Inverter Cassette System
- Location: Traralgon, Gippsland
- Sector: Commercial
- Space type: Quick service restaurant
- Services provided: Removal of old cassette unit, supply and installation of 14kW Daikin inverter cassette, crane lift for rooftop outdoor unit placement
The Situation
For a busy food service business like Subway, a comfortable in-store environment is not optional. Customers and staff need reliable air conditioning throughout the day, and an ageing cassette unit that is no longer performing efficiently puts both comfort and running costs at risk. Older systems work harder to maintain temperature, which drives up energy bills without delivering the results a modern inverter system can achieve.
The existing unit had reached the end of its life and needed replacing. With a high-traffic location in Traralgon and customers coming through the door all day, the priority was a fast, clean changeover with minimal impact on store operations.
The Solution
Kool Air specified a 14kW Daikin premium inverter cassette system as the replacement. Cassette units are the go-to choice for retail and food service environments because they distribute conditioned air evenly in four directions from a ceiling-mounted panel, covering the full floor area without wall-mounted units getting in the way of signage, fitout, or workflow.
The inverter technology in the new Daikin unit is a significant step up from older fixed-speed systems. Inverter compressors adjust their output continuously to match the cooling or heating demand of the space, rather than switching on and off at full power. For a store open long hours every day, this translates directly into lower energy consumption and more consistent in-store temperatures.
The rooftop placement of the outdoor unit required a crane to lift it safely into position, which the Kool Air team coordinated and managed as part of the installation. It is the kind of logistical planning that separates a professional commercial air conditioning installer in Gippsland from a basic trade job.

The Outcome
Subway Traralgon now has a modern, energy-efficient 14kW Daikin inverter cassette system delivering consistent, even comfort throughout the store. The new unit runs quieter and more efficiently than the old system it replaced, which means a better environment for staff working long shifts and a more comfortable experience for every customer walking through the door. The rooftop outdoor unit is neatly positioned and out of the way, and the ceiling cassette panel sits cleanly within the store’s existing ceiling grid.
