Who we work with

Built for builders, strata, and serious homeowners.

We work with private homeowners, custom builders, body corporates, strata managers, and commercial fit-out partners. Same engineering rigour, scaled to the project.

Residential

Homeowners & Renovators

Custom hydronic design that respects your floor plan, joinery and finishes — from heritage cottages to architectural builds.

Trade

Builders & Architects

Spec partner on dozens of high-end Australian builds. We work to your construction program, not against it.

Multi-residential

Strata & Body Corporate

Hot water plant servicing, central boiler upgrades, common-area heating and 24/7 incident response.

Commercial

Hotels, hospitals, schools, offices and industrial facilities. We bring our own plant-room install crews.

By the numbers

A track record that speaks for itself.

Twenty-five years, three states, thousands of installs. We have built our reputation one job at a time — by showing up, doing what we said we would, and standing behind our work.

Every home is different. We design the network around your slab, joinery and energy source — not the other way around. Mix and match across rooms.

How we work

A four-stage handover. No surprises.

From kerb to commissioning. We treat every job — a single radiator swap or a 200-zone commercial fit-out — with the same engineering rigour.

01

Consult

Phone, plans or site visit. We listen for what you actually need — comfort, efficiency, aesthetics.

02

Design

Heat-loss calculation, zone plan, energy-source matchup, fixed quote — all back within 24 hours.

03

Install

Our in-house tradesmen install everything to AS/NZS standards — neat pipework, tested, photographed.

04

Service

Annual service, on-call repairs and 24/7 emergency line for the lifetime of the system.

Trusted nationwide

"The system has changed our lives. From the first quote to the final commissioning, the AHHAC team were punctual, on-budget and professional on site every single day. We've now had them back for two more properties."

Common questions, clear answers.

Do you service my area?

We service every state in Australia from our three workshops in Sydney, Melbourne and Queensland — covering Greater Sydney, the Blue Mountains, Canberra, Wollongong, Newcastle, Greater Melbourne, Mornington Peninsula, the Gold Coast, Brisbane, the Sunshine Coast and most regional corridors.

How quickly can you provide a quote?

Within 24 hours for most enquiries. Send us your floor plans, project type and timeline via the contact form and we'll come back with a heat-loss calculation and a fixed-fee design proposal.

What's the difference between hydronic and ducted heating?

Hydronic uses warm water through pipes (radiators, underfloor) — silent, even, healthier, 25–35% lower running cost over time. Ducted blows heated air through ducts — cheaper to install but louder, less even, and more expensive to run.

Do you do emergency plumbing 24/7?

Yes — our emergency line is staffed every hour of every day. Typical dispatch is within 30–60 minutes. Burst pipes, blocked sewers, hot water failures, boiler shutdowns — call 1300 76 53 39.

Which brands do you install and service?

We're an authorised supplier of Maxa heat pumps, Viessmann boilers and DHW heat pumps, Rheem and Rinnai hot water, ThermaSkirt™ skirting heating, plus Bosch, Mitsubishi, Daikin, Stiebel Eltron and others.
