Air conditioning systems

All types of air conditioning systems for your Brisbane home or business

“What type?”

That’s often the first question that crosses a person’s mind when considering a new air conditioning system for their home or business.

In many cases, deciding which system to install is a question of costs versus benefits. In others, it’s a matter of choosing a system designed to fulfil your needs. In either case, you don’t pay for the wrong system!

So if you’re looking to install an air conditioning system for your home, office, or other type of commercial setting, but aren’t sure where to start, let Tri-Tech’s team help you understand the benefits of a variety of systems and which one is most suitable for your specific needs.

Air conditioning systems we install:

Multi split system

Choosing the right air conditioning system for your space

Choosing the right system isn’t always straightforward, but the team at Tri-Tech takes the time to assess your space, how it’s used, and what you actually need from your air conditioning. From there, we guide you towards a system that will perform properly day to day based on details like:

Room size

Matching system size to your space for balanced, consistent performance.

Cooling capacity

Capacity that handles demand without overworking the system.

Energy efficiency rating

Systems that keep long-term running costs manageable.

Climate & insulation

Factoring in Brisbane conditions and how well your space retains air.

Type of unit

We recommend system types that suit your layout and daily use.

Installation

Planning installation carefully to guarantee reliable performance, always.

We work with and install the following air conditioning systems

Wall mounted split system

Stay cool in summer and warm in winter with your choice of high-quality split air conditioning systems. Tri-Tech offers sales & installation, as well as maintenance and repair services for some of Australia’s most trusted split systems.

  • Inverter, reverse cycle technology
  • Cost-effective to install and run
  • Can be installed in just a few hours
  • Easy to maintain

Multi split system

Multi split systems allow more than one indoor unit to run on a single outdoor unit. A selection of indoor unit types ensures cool and comfortable air can be effectively mixed through a home or office space.

  • Great option for limited floor or roof space
  • Easy to install
  • Independent climate control in multiple rooms

Ducted air conditioning

Keep the whole family cool (or warm) with a fully ducted system. If you’re looking to cool your entire home or any other large space, ducted air conditioning is an ideal solution.

And for businesses with multiple zones in one area or one large open space, a ducted system delivers a comfortable, balanced air flow and overall efficient solution, all from a single control point.

  • Discreet air conditioning for year-round comfort
  • Cool in summer, warm in winter
  • Easy control from one panel
  • Unobtrusive vents that don’t stick out

Ceiling cassette units

Ceiling cassette systems are installed right within your ceiling and distribute air in multiple directions. Because they sit flush with the ceiling, they offer a more discreet look while still handling larger areas (like offices, retail spaces, and open-plan areas) more effectively.

  • Even airflow across larger open spaces
  • Discreet ceiling-mounted design
  • Ideal for offices and commercial settings
  • Keeps walls clear and uncluttered

Bulkhead units

Bulkhead systems are concealed within a ceiling cavity or bulkhead, with only a grille visible, and are a popular choice that suits apartments and modern spaces where maintaining a clean interior design is important.

  • Discreet, built-in appearance
  • Ideal for apartments
  • Concealed installation (with visible grille only)

Floor console systems

Installed at ground level, floor consoles are a great alternative if your wall space is limited or might not be suitable. Most often used in rooms with large windows or low walls, they provide strong, direct airflow and are easy to access – which is useful for both operation and maintenance.

  • Perfect for limited wall space
  • Strong, direct airflow at lower levels
  • Easy access for control and cleaning
  • Suits older homes or renovations

FAQs

Here is a simple two-step formula you can use:

  • Calculate the area of the room.
  • Multiply the area by 150* watts.

For example, if your room is 6m by 5m:

  • 6m x 5m = 30 m2
  • 30 m2 x 150 watts = 4500 watts (4.5Kw)

*It’s also useful for us to know which direction the rooms face. Southerly facing rooms require less cooling in summer but more heating in winter. If the room is facing west, or if it faces north and has large windows, use a factor of 180 watts for your calculation. In our example above, a westerly facing room would need a 5.4Kw system.

A multi-split system is used when a home air conditioning unit is required in more than one room (a bedroom, a study and a family room, for instance), can be used for an entire house with up to 6 indoor units; if that’s your requirement, you need a ducted system.

Multi-split systems are often viable in small commercial applications as well. Ceiling or floor console and ceiling cassette models are also suitable for some domestic and small office environments.

Inverter air conditioners are more economical to operate and quieter to run than conventional units. They can handle wider extremes in temperature, are smoother and more stable in operation and reach the desired temperature more quickly than conventional air conditioners.

In order to maintain optimal performance, your split system should be serviced annually. While this may seem excessive, split systems need to be checked for blockages and cleanliness to reduce the likelihood of breakdown or transfer of bacteria.

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.

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
