Aircon piping & trunking work
New pipe runs, extensions, replacements, and trunking concealment. We confirm routing and access on-site before pricing. We’ll assess first, then confirm whether this is the right scope before you book.

What piping & trunking work covers
Piping and trunking work covers the copper refrigerant lines, drainage, insulation, and the trunking that conceals it. Most jobs come out of renovation work or fixing a previous install that went wrong. We quote after seeing the site, because the right route depends on the wall type, access, and what your contractor's planning. Common situations where piping work fits:
New installation needs pipe runs
Copper refrigerant lines, insulation, drainage, and trunking planned from scratch.
Renovation changes the route
Walls, cabinetry, ceiling work, or outdoor unit placement have shifted the original route.
Existing piping is damaged or poorly routed
Corrosion, insulation damage, poor drainage slope, or repeated gas loss all point back to the line set.
When piping & trunking work isn't suitable
Some related work needs a different starting point before piping gets touched.
Whole-house electrical is needed
We handle aircon-side wiring only. DB board upgrades and whole-house work need a licensed electrician.
Wall hacking or structural work is the main scope
We'll advise where penetrations are needed, but hacking is your contractor's scope.
The unit fault hasn't been diagnosed
Start with on-site inspection if the symptom could be the unit, not the piping.
What you get
An aircon line set that's reliable, serviceable, and matched to the install.
Route planned before quoting
We check distance, wall type, access, drainage, and finishing constraints before work starts.
Pipe integrity verified
We pressure-test new or replaced pipe runs before introducing refrigerant.
Drainage slope checked
Condensate flow planned end-to-end so water doesn't back up after installation.
How a piping job works
From your first message to a tested line set, here is what happens.
You message us
Tell us the situation, a new install needing pipe runs, a renovation reroute, or damaged piping, and what your contractor's planning around it.
We survey the route
We check the wall type, distance, access, drainage path, and how the route fits the finished space. No quotes over the phone.
We quote the scope
Copper lines, insulation, drainage, and trunking, priced as one job around your layout. Nothing starts without your approval.
We run and conceal the lines
We install or replace the copper piping and drainage, then finish the trunking or concealment to suit the wall.
We pressure-test and commission
We pressure-test and vacuum the new run before charging, then verify cooling and drainage.
What we check before piping work
Piping quality decides cooling performance, refrigerant integrity, drainage reliability, and how clean the finished route looks.
Refrigerant line route
Distance, bends, wall penetrations, copper diameter, insulation condition, and whether reuse is sensible.
Drainage path
Condensate slope, discharge point, floor-trap access, pump need, and backup risk.
Trunking and concealment
Visible trunking, false-ceiling route, cabinetry constraints, and how the route fits the finished wall.
Testing and commissioning
Pressure test, vacuum, refrigerant charge, drainage test, and cooling check once the pipe work's connected.
