Aircon Installation

When renovating a home or office in Singapore, air conditioning is often one of the most important considerations. With our tropical climate, an aircon system isn’t just a luxury—it’s a necessity. But here’s a common question many homeowners and business owners ask: Should aircon installation be done before or after the renovation process?

Why Timing Matters for Aircon Installation

Installing an air conditioner isn’t just about placing a unit on the wall. It involves piping, electrical wiring, drainage planning, and positioning to ensure the system works efficiently. If done at the wrong stage of renovation, you may face:

  • Rework on walls or ceilings

  • Added costs for adjustments

  • Delays in the renovation timeline

  • Risk of damaging new finishes

This is why the timing of installation matters just as much as the brand or type of aircon you choose.

Installing Aircon Before RenovationAdvantages:

  1. Better Piping and Wiring Integration

    Installing before renovation allows the aircon piping and trunking to be neatly concealed within false ceilings, walls, or built-in furniture. This results in a cleaner, more modern look.

  2. Flexibility in Unit Placement

    Without finished walls or furniture to restrict positioning, technicians can place indoor and outdoor units in the most efficient locations.

  3. Smooth Coordination with Renovation Contractors

    Your aircon technicians and renovation team can work hand-in-hand to design a space that balances aesthetics with functionality.

  4. Fewer Risks of Damage

    Since walls, floors, and carpentry are not yet completed, there is less risk of damaging finished surfaces during installation.

Disadvantages:

  • Renovation dust and debris can settle inside newly installed aircon units if they’re not protected properly.

  • You may need to request the aircon team to come back for a final check and cleaning after renovation is completed.

Installing Aircon After RenovationAdvantages:

  1. Protection from Dust and Damage

    With all the heavy drilling, carpentry, and painting completed, your aircon units won’t be exposed to dust and debris during renovation.

  2. Clearer Aesthetic Decisions

    Once your renovation is complete, you’ll have a better idea of the room’s layout and can decide where the unit should be placed for comfort and appearance.

Disadvantages:

  • Concealing piping and trunking becomes much harder, which may affect the interior design.

  • More drilling or hacking may be required, leading to extra costs.

  • Risk of damaging freshly painted walls, ceilings, or carpentry when installing aircon trunking

  • Limited flexibility on where the indoor and outdoor units can be placed.

The Best Approach: A Two-Stage Aircon Installation

At Letscool Aircon and Services, we often recommend a two-stage installation process for clients undergoing renovations:

  1. Pre-Renovation (First Stage)

    • Installation of copper piping, trunking, drainage pipes, and electrical wiring.

    • Careful coordination with your renovation contractor to conceal trunking and ensure proper placement.

  2. Post-Renovation (Second Stage)

    • Installation of the indoor and outdoor units after all major dusty works are complete.

    • Final testing, commissioning, and cleaning to ensure your aircon runs smoothly.

This approach gives you the best of both worlds: neat concealed piping without risking dust damage to your aircon units.

  • Consider energy efficiency: Choose inverter models to save on electricity bills.

  • Think about future needs: If you might expand or add rooms, plan the aircon capacity accordingly.

  • Don’t cut corners: Proper installation ensures a longer lifespan and better performance.
