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.
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.
If you’re deciding to invest in a rooftop package unit, then you’ll likely be looking a total guarantee of confidence in both the equipment and the team installing it. But don’t worry, because Tri-Tech works with the world’s commercial air conditioning brands known for quality and long-term performance.
The Tri-Tech team, working across the whole of the South East Queensland region, are there to install, service, upgrade, and replace rooftop systems for Brisbane businesses across a wide range of industries.
That means from installation to ongoing support, you’ll be dealing with a team that has the experience to know what local businesses need from their commercial air conditioning and how to get the most from their rooftop package units.
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.
