Air conditioning installation isn’t as simple as just dropping in a system. It takes a lot of planning and thought, with careful consideration given to factors such as on-site insulation, windows, room volume, and electronics usage.

Above all, that they’re quiet, reliable, and energy-efficient. Mitsubishi systems are used widely across both homes and businesses or larger commercial spaces, because when installed and maintained properly, they perform consistently over time.
For most systems, a professional service once a year is a good baseline. If the system runs heavily (like in an office or high-use environment), then more frequent servicing of maybe twice annually might be more appropriate to keep it performing properly and to catch any issues early.
Because air conditioning systems involve electrical work and refrigerants, which must be handled by licensed technicians, professional installation is always necessary. If you try to install your unit yourself, it’s likely that you won’t be able to properly optimise how the system will perform long-term, too. So it’s always best to leave to professional, licensed installers like the team at Tri-Tech.
Warranty coverage is provided by the manufacturer and can vary depending on the specific system. But as authorised dealers and warranty agents, we’ll help you with warranty servicing and help manage the process if anything needs attention.
One of the most important things you can do on your own is keep your filters clean, which does a huge amount to help maintain airflow and the power of the unit. It’s also worth keeping the area around the outdoor unit clear and paying attention to any changes in performance, so issues can be addressed early.
