Everything
under
one roof.

Comfort, compliance and plant that runs quietly for twenty years.

Design through to commissioning, and the hard part, actually operating it, across office, retail, healthcare, hospitality and industrial facilities. Chilled water, VRF, split systems, DX, ventilation and air quality all sit under the same team.

Every HVAC scope ships with a BMS strategy, commissioning records, O&M manuals and a named engineer on lifecycle.

Keeping product cold, compliant and on-shelf from the store back to the DC.

From supermarket cases and walk-ins to ammonia plant rooms and trans-critical CO₂ systems, our refrigeration team runs the full lifecycle, design, install, commissioning and lifecycle maintenance. Registered on every site, instrumented where it matters.

We hold manufacturer accreditations with Danfoss, Bitzer, Emerson, Carel and LU-VE, and report leak rates, energy and uptime monthly against your SLA.

Licensed electrical, wired into every mechanical scope we deliver.

Our electrical division exists so we don't have to wait on a subbie to energise a plant at 11pm on a Saturday. Master Electricians accredited, all PrescribedElectricalWork signed off to AS/NZS 3000.

We cover the full spread, switchboard upgrades, lighting retrofits, EV charging, data & comms and power quality investigations, on the same ticket as the mechanical work.

Certifying plumbers and gasfitters, on the same job sheet as the mechanical crew.

Plumbing lives next to the plant, chilled water make-up, condensate, tundishes, gas trains to rooftop units, hot water rings serving the same building we're conditioning. Running it in-house means one set of penetrations, one set of brackets and one commissioning record.

Certifying Plumbers, Gasfitters & Drainlayers on staff, all PGDB-registered and signed off to G12 / G13 of the NZBC.

Mechanical, electrical and controls design, by the same team that installs it.

ACSL provides mechanical and electrical building-system concept development, design, installation and commissioning for architects, consultant engineers and property owners — without the disconnect that happens when one company designs and another builds.

Three design streams under one team, run through a design-and-build method that takes a project from preliminary meetings and developed design through estimating, construction and commissioning.

One contract across your portfolio, with numbers you can actually report on.

PPM cycles, reactive desk, compliance reporting and lifecycle capex, bundled under a single master service agreement. We'll take over your asset register or build you one from scratch in the first six weeks.

Monthly client reporting, quarterly QBR, and a named account manager. No ticket system hide-and-seek.

Medical gas systems, designed, priced, installed and maintained to healthcare spec.

ACSL designs, prices, installs and maintains complete medical gas systems for hospitals, day-surgery, dental and aged-care facilities, from the plant room through to the outlet at the bedhead.

Every install is pressure-tested, purity-verified and certified, with commissioning records and alarm-system sign-off handed over on completion.

Fire protection across wet and dry systems, installed, certified and maintained with the rest of your building services.

ACSL delivers both sides of fire, wet systems that get water to the fire, and dry systems that detect it, warn people and hold the building together. Designed and installed alongside your HVAC, electrical and plumbing, on one programme with one point of contact.

Every system is installed to the relevant NZS standards, certified, and kept compliant with scheduled testing and BWoF / IQP sign-off.
