Concealed vs Exposed Aircond Piping — Aesthetics, Cost & Which to Choose
Should you hide your aircond pipes inside the wall or run them externally? Compare aesthetics, cost, maintenance access, and when each option makes sense for Malaysian homes.

Concealed or Exposed Piping — Which Is Right for Your Home?
The choice between concealed (in-wall) and exposed (external trunking) piping affects your home's aesthetics, installation cost, and future maintenance access. Our installation specialists explain both options honestly.
Quick Comparison
| Factor | Concealed Piping | Exposed Piping |
|---|---|---|
| Aesthetics | Invisible — clean walls | Visible trunking/casing |
| Cost (new build/reno) | RM 200-400 per point | RM 0 extra (included in base) |
| Cost (existing home) | RM 500-1,000 per point | RM 0 extra |
| Installation time | 2-3x longer | Standard time |
| Maintenance access | Harder (wall access needed) | Easy (trunking opens) |
| Leak detection | Harder to spot | Visible immediately |
| Best timing | During renovation | Any time |
When Concealed Piping Makes Sense
- During renovation or new build — pipes laid before plastering, zero extra wall damage
- Living rooms and master bedrooms — where aesthetics matter most
- Long pipe runs — visible trunking across a long wall looks unsightly
- High-end homes — clean, invisible finish matches premium interior design
When Exposed Piping Is the Better Choice
- Existing homes without renovation plans — hacking walls for concealed pipes means repainting entire rooms
- Rental properties — easier to maintain and replace
- Budget installations — saves RM 200-1,000 per point
- Service areas and kitchens — where aesthetics are less important
- Easy maintenance priority — trunking opens easily for inspection and repair
Exposed Piping Done Right
Even exposed piping can look clean and professional when done properly. Our expert installers follow these standards:
- White PVC trunking — color-matched to most Malaysian wall colors
- Straight, level runs — no sagging or diagonal shortcuts
- Minimal wall penetrations — one clean hole, properly sealed
- Hidden routing where possible — behind curtains, above cabinets, along ceiling edges
Cost Breakdown
| Scenario | Concealed | Exposed |
|---|---|---|
| New build / during reno | RM 200-400 extra | RM 0 (included) |
| Existing home (brick wall) | RM 500-800 extra | RM 0 (included) |
| Existing home (concrete) | RM 800-1,200 extra | RM 0 (included) |
Our Recommendation
If you're renovating: Go concealed — the marginal cost is small and the result is much cleaner.
If your home is already finished: Go exposed with professional trunking — hacking walls for concealed pipes costs more in repainting than the piping itself.
