Hotels, hospitals, schools, offices, retail — we run a dedicated commercial book with on-call crews and fixed maintenance contracts.
Commercial plumbing isn't just bigger — it's different. Different codes (AS/NZS 3500), different pressures, different documentation requirements, and very different consequences for downtime.
Our commercial team handles new fit-outs, planned maintenance, central plant upgrades, and priority incident response under SLA.
Hospitality (hotels, restaurants, function venues), Healthcare (private hospitals, aged care, day surgeries), Education (schools, universities, child care), Retail (shopping centres, big-box, food courts), Industrial (warehouses, light manufacturing).
Yes — we offer tiered SLAs: 1-hour, 4-hour and next-business-day response, depending on building criticality. Hospitals and aged-care facilities typically get 1-hour; offices and retail get 4-hour. Choose your tier per site.
Yes — $20M public liability cover, full workers comp, and asbestos-aware crew where the building age requires it. Insurance certificates available on request.
Yes — we install BMS-compatible plant (BACnet, Modbus) so facility managers can see and control hydronic plant from their existing dashboards. Energy monitoring and alarm integration included.
Yes — we design, install and service commercial hot water and hydronic plant, including cascaded MAXA HWA2 reversible heat pumps that deliver heating, cooling and domestic hot water to 78 °C from one system. Typical sites: hotels, hospitals, aged care, schools, gyms and strata.
We service commercial clients across NSW, ACT, VIC and QLD from our six showrooms — Sydney, Melbourne, Brisbane, Albury, Canberra and Newcastle — with SLA-backed response tiers per site.
"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."
"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."
"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
