Rooftop package units

What is rooftop package air conditioning?

Rooftop Package Units (or RTUs) are self-contained commercial air conditioning systems designed specially for heating and cooling larger buildings from a single unit installed on the roof.

Because all major components are housed together, they’re a hugely practical and space-saving option for many businesses, retail centres, offices, schools, warehouses, and more.

  • Space-saving rooftop installation
  • Heating and cooling in one unit
  • Easy service access
  • Flexible zoning options
  • Efficient operation

Rooftop package air con units built around your commercial site

The mobile tech team at Tri-Tech, with over three decades of experience in major commercial air con systems, takes a tailored approach to every rooftop package unit installation because we know that every commercial property works differently. Occupancy levels, operating hours, internal heat loads, ceiling heights, and building layout all affect how an air conditioning system should perform.

Rooftop package units mean:

  • Strong whole-building coverage
  • Zoned temperature control
  • Efficient operation
  • Reliable year-round comfort
  • Simple central controls
  • Reduced indoor plant space
  • Scalable for growing sites

FAQs

A rooftop package unit is an all-in-one commercial air conditioning system installed on the roof of a building, which contains the main heating and cooling components in a single unit. They’re most commonly used in offices, warehouses, retail stores, schools, restaurants, medical centres, gyms, and other commercial spaces that need reliable whole-building climate control.

Rooftop units can be very efficient when correctly sized and installed for the building, since modern systems are designed to improve performance and reduce wasted energy – especially when paired with zoning or smart controls.

That’ll depend on your floor area, ceiling height, insulation, occupancy levels, equipment heat load, and trading hours. But our team can help you properly assess the size of your site and recommend the right system so you don’t end up with one that’s too small or oversized.

Yes, many rooftop package units offer both heating and cooling, making them a high-powered year-round solution for commercial buildings.

Yes, older systems can be repaired or upgraded in most cases: our mobile technicians can inspect the unit, diagnose faults, and advise whether repair or replacement is the better long-term option.

Rooftop units are often better for larger commercial sites because they can handle bigger spaces, keep equipment out of working areas, and provide centralised control across multiple zones.

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
