Where’s the job?

Scope of Works

• survey the route for refrigerant lines, condensate drain and cable runs

• measure, cut and prepare copper tubing and fittings, including flaring or brazing joints

• install thermal insulation and protective conduit, secure lines to walls, joists or rafters

• form and seal wall or roof penetrations, core drill where required and weatherproof external runs

• pressure and vacuum test the system, check for leaks and charge/reclaim refrigerant by an F‑Gas qualified engineer

• connect to indoor and outdoor units, run electrical isolator if required and complete commissioning checks

• remove and dispose of old tubing and contaminated materials following regulatory requirements

Typical Cost

Time on Site

Typical tubing runs for a single domestic split system take 2–4 hours on site; factors that extend it include long external runs, chasing walls or ceilings, need for scaffold or cherry picker, reclaiming old refrigerant, or waiting for parts

Questions to Ask Your Tradie

• are you F‑Gas certified and insured to handle refrigerant and provide paperwork

• what length of copper tubing, insulation and fittings are included in the quote

• will you perform vacuum and pressure tests and provide a leak test or commissioning report

• do you include sealing and weatherproofing of penetration points and who makes good after chasing

• what extras might be charged (scaffold, hot‑works permit, extended pipe runs) and how are they priced

• what guarantees cover workmanship and materials and do you provide documentation for future servicing

How to Avoid Surprises

• clear access to indoor and outdoor unit locations and mark where you want the pipe route

• arrange parking or loading space for van and materials close to the work area

• confirm if scaffold or working‑at‑height permits are needed for high external work

• move fragile items, protect carpets and floors, and secure pets during work

• check leasehold rules or building management requirements for external works or alterations
