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.

What do our customers have to say?

Couldn’t be happier with the service from Tri-Tech. From booking the appointment through to the technician completing the work, everyone was helpful and professional. The air conditioning system was given a really thorough clean and service, and it’s running noticeably better now. Great local company and highly recommended.

We had 4 split systems installed by Tri-Tech Air Conditioning around 5 years ago and have continued to have them serviced every year. We’ve always been really happy with the service and professionalism. From the friendly office staff through to the technicians, everyone has been reliable, helpful and great to deal with. Highly recommend.
Always on time, always courteous, and very thorough.

Excellent experience with Tri-Tech Air Conditioning. The technician ‘Aidan’ arrived on time, was friendly and professional, and did a very thorough service of our systems. He took the time to explain everything clearly and made sure everything was running properly before leaving. Would definitely recommend Tri-Tech.

Outstanding service. Tritech installed a ducted system for us. Paul gave us a quote quickly and was able to thoroughly explain what their works would entail. The team was professional and tidy, and made sure everything was done well. You could barely tell a team came in and removed a ducted system and installed a new one, it was that clean. Workmanship was great. No complaints and we would certainly reach out to them again for any air conditioning related things in the future.

We got several Aircons through tritech air-conditioning. Darren was amazing from moment of quoting to seeing the job through. I highly recommend Tri-texh air-conditioning.
I had such a great experience with Tri-Tech Airconditioning & Electrical. Andrea who I dealt with was fantastic from start to finish friendly, organised and genuinely cared about getting things right. Everything was explained clearly, the service was prompt, and the job was done properly with no issues.

I’ve had Jayden and the Tri-Tech family install air conditioners across two of my houses, and they have impressed me every time. Their level of service is outstanding — always efficient, highly professional, and clearly experts in what they do. On top of that, their pricing is very competitive. I wouldn’t hesitate to recommend them to anyone looking for quality air conditioning installation.
All my dealings with Tri-Tech have been fantastic. We had 2 air cos fitted a couple of years ago and just recently another older unit (not installed by TT) repaired and serviced. From office staff to technicians – courteous, efficient, clean and professional! Shout out to Xavier great job!

Our experience with tri-tech was great. All the people we dealt with were fantastic and the team that installed our ducted system were respectful and professional. We also had an individual unit installed and we were very happy with how the work was carried out. When there was a problem, tri tech were quick to help solve it and rectify the problem without delay. Highly recommend.

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
