Australia Commercial Heating, Ventilation and Air Conditioning Rooftop Units Market Size, Share, Growth and Forecast, 2025-2035

Replacement cycles and refrigerant rules set rooftop demand

The Australia commercial heating, ventilation and air conditioning rooftop units market was valued at USD 202.5 million in 2025 and is projected to increase from USD 221.0 million in 2026 to USD 364.7 million by 2035, registering a CAGR of 5.72% during 2026–2035. Demand comes from shopping centers, hotels, restaurants, offices, warehouses, schools and clinics that heat and cool single-story or low-rise spaces with packaged units mounted on the roof. New South Wales and the Australian Capital Territory held the largest regional share, 33.7% in 2025, because Sydney holds the largest stock of retail and office floor space. Queensland and the Northern Territory form the fastest-growing region at 6.03% a year, as population growth and long cooling seasons lift installed capacity. At the same time, refrigerant import bans on smaller equipment and lower-impact refrigerant ranges from local makers are pushing owners to plan rooftop replacements well before older units fail.

Which packaged rooftop equipment does the estimate cover?

The estimate measures the value of new packaged rooftop units sold to commercial buyers in Australia, including reverse-cycle heat pump packages, cooling-only packages and gas-electric packages. It counts units from about nine kilowatts to well above 100 kilowatts, whether owners buy them for replacement, new buildings or added capacity.

The estimate excludes installation labor, ductwork, maintenance contracts, split systems, variable refrigerant flow systems and chillers. The value chain runs from manufacturers and importers through specialist distributors and equipment dealers to mechanical contractors, which install units for building owners, tenants, retailers and public agencies.

Reverse-cycle units lead while inverter models grow fastest

Why do reverse-cycle heat pumps hold the largest value?

Based on product type, the market is categorized into reverse-cycle heat pumps, cooling-only packages and gas-electric packages. Reverse-cycle heat pumps led with a 58.0% share of 2025 value, because one unit heats and cools most retail and office spaces without a gas connection. Reverse-cycle heat pumps grow fastest at 6.22% a year, as electrification rules and hotter summers favor all-electric equipment at each replacement.

How does replacement anchor rooftop unit demand?

Based on application, the market is categorized into replacement, new construction and capacity expansion. Replacement led with 57.0% of 2025 value, because a large installed fleet of older R410A and fixed-speed units reaches the end of its service life. Replacement also grows fastest at 5.99% a year, as refrigerant rules and energy disclosure push owners to replace units earlier.

Which building owners buy the most rooftop units?

Based on end-use industry, the market is categorized into retail and hospitality, offices and logistics premises, and education and healthcare. Retail and hospitality led with a 41.0% share of 2025 value, because shopping centers, restaurants and hotels run large single-story spaces. Education and healthcare grows fastest at 6.29% a year, as schools and clinics expand with population growth.

How is compressor technology shifting toward inverters?

Based on technology, the market is categorized into inverter compressors, staged compressors and single-stage fixed-speed compressors. Staged compressors led with a 40.0% share of 2025 value, because twin and tandem compressor designs dominate larger packaged units. Inverter compressors grow fastest at 7.10% a year, as variable-speed models cut part-load energy use and help owners improve building ratings.

Refrigerant limits, disclosure and building work lift demand

How does the refrigerant transition reshape replacement plans?

Refrigerant rules are pushing owners to plan rooftop replacements earlier, because older R410A fleets face rising service costs as gas supply tightens. Australia began phasing down hydrofluorocarbon imports on Jan. 1, 2018, and the phase-down reaches an 85% cut by Dec. 31, 2035, leaving a residual import allowance after that date, according to the National Environment Protection Agency. The agency says small split, window and portable units using refrigerant above 750 global warming potential were banned from July 1, 2024, and the ban widened on July 1, 2025 to multi-head split and variable refrigerant flow outdoor units. Ducted and larger packaged systems remain outside both bans for now. As a result, replacement holds 57.0% of 2025 value and grows at 5.99% a year.

Why does energy disclosure lift demand for efficient units?

Building owners face growing pressure to prove energy performance, which favors efficient rooftop units when old equipment is replaced. The Commercial Building Disclosure program requires energy efficiency information when commercial office space of 1,000 square meters or more is offered for sale or lease. The Energy Efficiency Council said in June 2024 that buildings disclosing under the program since 2012 had cut energy use by an average of 42%. Air conditioners above 65 kilowatts have also faced minimum energy performance standards since April 1, 2022, with seasonal efficiency ratings required at registration, according to the national Energy Rating program. In turn, owners that chase better ratings increasingly specify variable-speed units when they replace older packages.

How does selective non-residential building lift new installs?

Non-residential construction is recovering unevenly, which supports new rooftop installations in retail, logistics, education and health projects rather than across every building type. The Australian Bureau of Statistics reported on Aug. 26, 2026 that non-residential building work done rose 0.5% in the June quarter and stood 11.5% higher than a year earlier. Approvals remain volatile, because the same agency said non-residential approvals fell 24.7% to A$8.26 billion in June 2026 after a record May. South Australia's Department of Treasury and Finance noted that national non-residential approvals had risen 41% in May to stand 65% higher than a year earlier. As a result, new rooftop orders follow building construction pipelines in growth corridors.

Why do hotter summers and electrification favor heat pumps?

Hotter conditions and state gas policy both favor reverse-cycle rooftop units over cooling-only or gas-fired packages. The Bureau of Meteorology's State of the Climate 2024 found that Australia has warmed by 1.51°C since 1910, and that very high monthly maximum temperatures now occur about 11% of the time, against 2% in 1960–1989. In Victoria, the state government says that new hospitality buildings must be built all-electric from Jan. 1, 2027, with gas space heating excluded. RenewEconomy reported that the government announced on June 24, 2025 that the rule covers new commercial buildings except industrial, manufacturing and agricultural premises. As a result, reverse-cycle units hold 58.0% of 2025 value, as owners treat the rooftop package as the building's main heat pump.

Low-GWP ranges, inverter control and retrofit openings

How is the shift to R32 and R1234ze changing rooftop ranges?

Manufacturers are rebuilding packaged ranges around lower-impact refrigerants, which changes what owners buy when older R410A units fail. Daikin Australia said in September 2020 that R32 has a 66% lower global warming potential than R410A, the refrigerant then in common use. Climate Control News reported in June 2026 that Temperzone's Ecolite OPA uses R32 and was designed mainly to replace older R410A rooftop systems with a similar footprint and spigot locations. The same report said Temperzone's Environex OPA uses R1234ze with twin compressors and runs in cooling mode at ambient temperatures up to 60°C. In turn, like-for-like replacement becomes simpler, because new units fit existing roof curbs and ducts.

Why is the rise of inverter compressors and controls notable?

Variable-speed compressors and integrated controls are spreading from small split systems into packaged rooftop equipment, which raises the value of each unit sold. Temperzone's Econex HWP range uses R32 inverter technology to replace fixed-speed R410A water-cooled packages, Climate Control News reported. Rinnai Australia acquired the controls maker iZone on Oct. 19, 2023, saying that owning controls lets it offer a complete system with after-sales support. ActronAir highlighted zoning and integrated smart controls for light commercial uses at its ARBS 2026 stand, Climate Control News reported in April 2026. As a result, inverter compressors grow at 7.10% a year, the fastest technology.

Is there an opening in education and healthcare buildings?

Schools, clinics and hospitals offer a growing opening, because population growth adds floor space that must stay comfortable through longer hot seasons. The Australian Bureau of Statistics reported that the population grew by 392,700 people, or 1.4%, in the year to March 31, 2026. The Commercial Building Disclosure expansion roadmap says public hospitals and schools will be pursued through jurisdictional commitments before any direct regulation. The Bureau of Meteorology notes that extreme heat has caused more deaths in Australia than any other natural hazard, which raises the priority of reliable cooling in care settings. In turn, education and healthcare grows at 6.29% a year, the fastest end-use industry.

Can retail and hotel retrofits open a replacement window?

Shopping centers and large hotels could open a broad retrofit window, because both face likely energy ratings under the disclosure program's expansion. The roadmap describes shopping centers as large energy users with large air conditioning, heating and lighting requirements, and it would start with centers above 5,000 square meters. It names hotels with more than 100 rooms as first in line for hotel ratings, with full roadmap implementation by 2035. Rinnai Australia sells APAC commercial package units and acquired Perth rooftop package maker Specialized Engineering in April 2017. As a result, retail and hospitality holds 41.0% of 2025 value, and rated owners are likely to favor efficient replacements.

Capital limits, roof access and new skills slow upgrades

How do capital budgets delay replacement decisions?

Packaged rooftop units carry a high upfront cost once cranes, roof works and electrical upgrades are included, which leads many small owners to repair rather than replace. As a result, older fixed-speed units often stay in service well beyond their efficient life. Tenants who pay the power bills rarely fund the equipment, so landlords and tenants disagree on who should pay. Suppliers respond with staged replacement plans and service contracts that spread the cost over several years.

Why do roof access and site limits slow installs?

Rooftop replacement needs crane access, structural checks and short shutdowns, which are hard to arrange in busy shopping centers and city sites. In turn, projects can slip into cooler months or wait for tenant approval, which delays orders for distributors and dealers. New units that weigh more or need different curb sizes add steel and design costs. Manufacturers respond with replacement models that match existing footprints, spigot locations and duct connections closely.

How do new refrigerants raise skill and handling needs?

New refrigerants need updated handling, charging and leak-check practice for packaged units and the refrigeration compressors inside them, which adds training costs for mechanical contractors and service technicians. As a result, smaller contractors may hesitate to quote for newer equipment until their staff are confident with it. Owners also face uncertainty about which refrigerant will stay available longest. Manufacturers and distributors respond with product training, commissioning support and longer warranties for installers who complete their programs.

Why do split and VRF systems compete for projects?

Variable refrigerant flow and ducted split systems compete with rooftop packages in offices, clinics and multi-tenant buildings, because they offer zoning without large roof units. In turn, designers may choose split systems where roof space is limited or noise rules are strict. Import pricing and exchange rates also affect relative costs for equipment brought in from Asia. Rooftop suppliers respond with quieter units, zoning controls and simpler installation for single-story retail and warehouse buildings.

New South Wales leads while Queensland grows fastest

New South Wales and the ACT hold the largest regional share

New South Wales and the Australian Capital Territory held a 33.7% share of 2025 value and grow at 5.63% a year, because Sydney and Canberra hold the largest stock of offices, shopping centers and public buildings. The zone had 9.16 million residents at March 31, 2026, according to the Australian Bureau of Statistics. Its large office stock also falls under national disclosure rules for spaces of 1,000 square meters or more. As a result, replacement of older units in established suburbs drives most regional demand.

How does electrification shape Victoria and Tasmania?

Victoria and Tasmania held a 24.6% share of 2025 value and grow at 5.73% a year, because cooler winters create strong heating demand alongside summer cooling. The zone had about 7.73 million residents at March 31, 2026, according to the Australian Bureau of Statistics. Victoria requires new commercial buildings to be all-electric from Jan. 1, 2027, which removes gas space heating from new projects. In turn, reverse-cycle packages replace gas-electric units in new Victorian retail and hospitality sites.

Western Australia and South Australia mix growth and local supply

Western Australia and South Australia held a 21.5% share of 2025 value and grow at 5.53% a year, because hot, dry summers make rooftop cooling essential. Western Australia had the fastest population growth of any state at 2.1% in the year to March 31, 2026, according to the Australian Bureau of Statistics. Rinnai Australia owns Specialized Engineering, a Perth-based maker of rooftop packaged units. South Australian non-residential approvals were 14% higher than a year earlier in May 2026, according to the state treasury.

Why are Queensland and the Northern Territory growing fastest?

Queensland and the Northern Territory held a 20.2% share of 2025 value and grow fastest at 6.03% a year, because long, humid cooling seasons keep rooftop units running for most of the year. Queensland's population grew 1.6% in the year to March 31, 2026, according to the Australian Bureau of Statistics. The zone had about 6.01 million residents at that date. As a result, new retail, logistics and school projects in south-east Queensland add steady demand for cooling-heavy packages.

Refrigerant bans, electrification rules and new ranges

Inverter drives, new refrigerants and smarter controls

• Inverter compressors vary their speed to match the load, which cuts energy use at part load and supports better building energy ratings.
• Lower-impact refrigerants such as R32 and R1234ze replace R410A in new ranges, which reduces exposure to the import phase-down and future equipment bans.
• EC fan motors adjust airflow electronically, which lowers fan energy and allows quieter operation on retail and hospitality roofs.
• Integrated zoning controls link rooftop units with sensors and building systems, which lets owners track performance and schedule maintenance remotely.

Local makers and global brands compete on fit and service

Competition combines Australian manufacturers with deep dealer networks and global brands that bring broad product ranges and service teams. ActronAir, an Australian company since 1984, sells commercial packaged rooftop units for small to large commercial spaces and cites ongoing investment in local manufacturing. Daikin Australia offers its UAYQ-C reverse-cycle rooftop packaged series in eight sizes from 16.3 to 84.2 kilowatts. Temperzone competes with R32 and R1234ze packaged ranges designed to replace older R410A units on existing roofs. Rinnai Australia sells APAC commercial package units, owns the Perth maker Specialized Engineering and acquired the controls maker iZone in October 2023. Suppliers compete on footprint match, delivery times, refrigerant choice and after-sales service, while mechanical contractors and specialist distributors strongly influence which brand an owner buys.

Which suppliers lead packaged rooftop equipment sales?

Credence Research view on packaged rooftop replacement

Credence Research's view is that Australian rooftop unit demand will grow steadily because a large installed base of older units must be replaced under tighter refrigerant and energy rules. Replacement remains the largest application, while inverter compressors grow fastest as owners chase better ratings. Queensland and the Northern Territory gain most from population growth and long cooling seasons. Suppliers that offer footprint-matched, lower-impact refrigerant units with strong installer support should win the most replacement work by 2035.

How the national rooftop unit estimate was built

The report uses 2025 as the base year on a calendar basis, and market values come from the Credence Research model. That model draws on official building activity and population statistics, regulator pages on refrigerants and energy standards, state electrification guidance, company product pages and trade media. Segment splits and regional growth rates are Credence Research estimates, while regional shares follow the client split. The report used no interviews or surveys at any stage of the research work.

Heat pump retrofits and efficient replacements drive growth
