FAQ

Common questions

What jobs do you typically take on?

Commercial fit-outs, factory and warehouse ventilation, commercial kitchen mechanical ventilation, industrial extraction, and replacement / upgrade of existing systems. Both new-build and retrofit.

How fast can you get on site?

Site survey usually within 48 hours of you reaching out. Detailed mechanical ventilation quote within 2 business days of the survey.

Do you handle the BCA / Section J compliance paperwork?

Yes. We issue AS 1668.1 and AS 1668.2 compliance certificates on commissioning, signed by our licensed mechanical engineer. Compliance reports formatted to suit private certifier or council requirements.

Can you design as well as install?

Yes. We design the full mechanical ventilation system to suit your space, use-class, and occupancy — including duct routing, fan sizing, and grille selection. We can supply shop drawings ahead of fabrication if your builder needs them.

What's the typical lead time?

From quote acceptance to a commissioned mechanical ventilation system: 4–10 weeks depending on building size and complexity. Smaller upgrades and fan replacements can be much faster.

Do you service existing mechanical ventilation systems?

Yes — service, repair, and upgrade of existing systems across Sydney including fan replacement, ductwork repairs, sensor recalibration, and balancing.
