Brisbane split system air conditioning

What is split system air conditioning?

Split system air conditioning delivers powerful, energy-efficient comfort without the high upfront cost or complex installation. It’s fast, affordable, and incredibly versatile, which is what makes it one of the most popular choices for both Brisbane homes and businesses.

Split systems are made up of two main components: one which sits inside your home, and the other outside. The two are discreetly connected by tubes and wires.

Each component serves a different function:

  • The external unit contains the compressor, which initiates the cooling process
  • The internal unit contains an evaporator coil that absorbs the heat from the air and a fan that blows refrigerated air into the room

Compared to old “window rattler” box units, split systems are fitted with much larger fans and compressors so that they can offer more powerful and effective cooling.

FAQs

It generally depends on everything from the size of the room to factors like ceiling height, insulation, and how much sun the space gets. As a basic guide, smaller rooms need lower-capacity units, while larger or open areas need more powerful systems.

Filters should be cleaned every few months, especially if the system is used regularly. If they’re left too long, airflow can be restricted and the system has to work harder. Some filters are reusable, while others may need replacing depending on the model.

Turn the system off and check for obvious issues like a blocked or dirty filter. Water leaks are often caused by blocked drain lines or buildup inside the unit. If the problem continues, it’s best to have it inspected to prevent further damage.

No, it is a legal requirement that a licenced technician with the appropriate refrigerant handling and electrical licence always performs air conditioning installations.

Yes, most modern split systems that Tri-Tech installs are reverse cycle, which means they can both cool in summer and heat in winter for all year-round solutions.

Absolutely outstanding service! From the first phone call to the final visit, the team was professional, punctual, and incredibly knowledgeable. They explained everything clearly, provided fair pricing, and completed the work efficiently without cutting corners. Our home is now cooler than ever, and the system runs perfectly.

It’s hard to find companies that truly care about customer satisfaction, but this one goes above and beyond. I highly recommend them to anyone needing air conditioning repair or installation — you won’t be disappointed!

I had a great experience with Tritech. They had great communication and were so efficient. There was no messing about or needing to follow up with them and everything worked out with ease. The price was super reasonable but ultimately I went with them because even from my first enquiry I could tell there would be no issues! Thank you

In November 2025 one of our 25 year old Daikin ducted air conditioning systems failed.The first time in 25 years.The part to fix it was no longer available.The team at tri – tech were amazing. They were able to think through a solution to repair the old system using a different approach rather than saying it was too hard and we needed to invest in a whole new unit.It saved us thousands of dollars.I would not hesitate to recommend this company.Every member of the team was so approachable and kept us in the loop at each step as different solutions were thought through.They are definitely a 5 star air conditioning company.

Could not ask for better service. Our experience with Tri-Tech has been brilliant, from the first conversation and quote to installation. Everyone on their team was a pleasure to speak to and so proactively competent and helpful. They were the only company we called that made the quoting process easy and effective.
The team members that came to our home, to confirm the quote and to install were a pleasure, great customer service and a quality job. I feel the whole team went beyond our expectations and I cant recommend them enough.

A very happy customer who has enjoyed the brilliant customer service. Thank you.

Hi All,
I would like to thank Darren Panter, Project Manager for recommending Mitsubishi Electric AP 5 kW Reverse Cycle Inverter Wall Mounted Split System as the air-conditioning unit that will suit our 2 bedroom apartment and for arranging Peter to decommission and remove our 14 years old no longer working aircon. Peter did a wonderful and neat job of installing the new reverse cycle unit. We are happy with the result and I would recommend these guys to anyone who needs a new air-conditioning unit for the house or an apartment.

I also had a wonderful support from the Admin staff from TriTech.

I highly recommend this company for the job well done!

Kindest regards,
Veronica
