Had a great experience with Snowflake Services for my aircon installation. Tony was super experienced and really took the time to explain options clearly without pushing any unnecessary upgrades.

Aircon Piping Work in Singapore
New pipe runs for a fresh layout, rerouting after renovation, or replacing damaged pipes from a previous install. We handle the pipe work itself — copper lines, drainage, insulation, and trunking — scoped to the site and quoted before anything starts.
How we approach piping work
Site assessed before quoting
Pipe routing depends on the building layout, wall construction, and discharge point. We check all of this before giving a number.
Pressure-tested before connecting
Every pipe run is pressure-tested after brazing to confirm the circuit holds. We do not connect the system until the test passes.
Coordinated with renovation timelines
For renovation work, we schedule around your contractor. Pipe runs go in at the right stage — after hacking, before plastering.
When this page applies
This covers pipe work that sits outside a standard installation or relocation. These are the most common situations.
- Renovation changed the layout and pipes need new runs or rerouting
- Previous contractor left incorrect or undersized pipe work
- Drainage is discharging to the wrong location or at the wrong slope
- Pipe insulation is deteriorating and causing condensation on walls
- Trunking needs to be replaced or extended to match new finishes
- New aircon pipe runs needed ahead of a unit installation
How piping jobs are handled
Every pipe job depends on the site. We assess the route, confirm the scope, and quote before starting. No assumptions about what is needed before we see the layout.
1. Describe the job and send photos
Tell us what needs to be done and the property type. Photos of the current pipe routing, discharge point, and any wall changes help us give a more accurate initial view.
2. Site assessment
We assess the pipe route, drainage gradient, wall penetrations, and trunking path on-site. For renovation work, we check against the new layout before quoting.
3. Clear scope and quote
You get a breakdown of what is included — pipe run length, drainage work, insulation, trunking, and any wall penetrations — before we proceed.
4. Pipe work and reinstatement
Pipes are run, brazed, insulated, and pressure-tested. Drainage is plumbed to the correct slope. Trunking is fitted and finished to match the wall.
5. Leak test and sign-off
The completed pipe work is pressure-tested before the system is connected. We confirm the circuit holds before leaving.
Pricing
Piping work is quoted per job based on the actual scope. Pipe run length, number of wall penetrations, drainage complexity, and trunking finish all affect the price.
- Quoted per job based on assessed scope
- Pipe run length and routing complexity are the main cost drivers
- Drainage replumbing and trunking quoted separately where applicable
- No work starts until the quote is agreed
Booking and visit timing
Timing depends on the job scope. Simple rerouting may take half a day. New pipe runs across multiple rooms may take a full day or more.
- Simple rerouting or drainage correction typically takes half a day
- Full new pipe runs across rooms may take a full day or more
- Site assessment is a separate visit for complex layouts
- We coordinate with renovation contractors where needed
What piping work covers
This is the pipe infrastructure itself — the copper lines, drainage, insulation, and trunking that connect the indoor and outdoor units.
- New copper pipe runs for fresh installations or layout changes
- Rerouting existing pipes after wall or layout modifications
- Drainage replumbing with correct slope to the discharge point
- Pipe insulation replacement where existing insulation has failed
- Trunking installation, extension, or replacement
- Wall penetrations and core drilling where new routes are needed
Common renovation scenarios
Most piping jobs come from renovation work. These are the situations we see most often in HDB and condo units.
- Wall moved or removed — pipe route no longer viable
- Aircon ledge or discharge point changed during renovation
- Old pipes reused but undersized for the new unit
- Drainage slope insufficient after floor level changes
- Trunking clashes with new ceiling or cabinetry
- Previous contractor left pipe work unfinished or incorrect
When piping work is not the right starting point
If the unit itself has a fault — not cooling, leaking, or showing an error — the fault should be diagnosed before touching the pipe work. Replacing pipes does not fix an electrical or refrigerant fault.
- Unit not cooling → diagnose the fault before replacing pipes
- Gas loss without visible damage → pressure test first to locate the leak
- Water leak from the indoor unit → check drainage blockage before replumbing
- Error code on display → read the code before assuming a pipe issue
