Pre-Installation Process: Site Survey & Planning (30–60 Minutes)

Before installers start any work, a proper site survey must be conducted. This ensures your new aircon system is compatible with your home layout, electrical capacity, and cooling requirements.

What Happens During the Site Survey?

  • Assessment of room size and measurement

  • Planning of trunking route

  • Checking outdoor compressor placement

  • Verifying electrical load and safety

  • Identifying potential issues like aircon water leakaging or weak airflow in existing units

This planning stage is crucial because improper installation may lead to problems such as aircon not cold, aircon light blinking, aircon error code, or premature system failure.

Why This Step Matters

A rushed or skipped survey can result in:

  • Wrong BTU capacity selection

  • Overloaded electrical circuits

  • Poor piping layout causing future leaks

  • Compressor overheating

By choosing experienced professionals like LetsCool Aircon and Services Singapore, you ensure your installation starts with accurate planning and safety checks.

Installation Timeline for Different Aircon Systems

The time required for aircon installation Singapore depends heavily on the number of indoor units and the complexity of the setup.

System 1 Installation (1 Indoor Unit): 2–3 Hours

A single-split system is the fastest to install. It typically includes:

  • Mounting indoor unit

  • Laying copper pipes and trunking

  • Setting up drainage

  • Installing outdoor condenser

If the layout is straightforward, it can even be completed within 2 hours.

System 2 Installation (2 Indoor Units): 3–5 Hours

More piping and wall work are required, especially if the rooms are far apart.

System 3 Installation (3 Indoor Units): 5–7 Hours

This setup includes:

  • More routing work

  • Longer piping

  • Additional electrical connections

Extra time is needed when drilling through reinforced concrete walls.

System 4 Installation (4 Indoor Units): 6–8 Hours

This is the most complex among residential setups. Multiple trunking routes, condensate drainage lines, and electrical circuits need to be coordinated.

Additional Work That May Extend Installation Time

Every home is different, which is why installation can sometimes take longer than expected. Here are the common reasons:

Replacing Old Aircon Systems

Removing old piping, trunking, brackets, and compressors can add 1–2 hours to the job.

Aircon Gas Top Up

If the new system requires refrigerant balancing or testing for leaks, technicians may perform a quick aircon gas top up which takes an additional 15–20 minutes.

Electrical Upgrades

Older HDB units may need upgraded wiring to safely handle the aircon load, which may extend the timeline.

Space Constraints

Condensers installed in tight service yards or high ledges require careful handling and safety equipment, slowing down the process.

Complex Trunking Routes

If you want hidden trunking or customised installation, expect an extended timeline.

Bad Weather

Outdoor condenser installation is delayed if installation staff cannot work safely on ledges or open spaces.

Testing, Commissioning & Handover (30–60 Minutes)

After all units are installed, technicians will test the system thoroughly.

Testing Includes:

  • Checking cooling performance

  • Inspecting for aircon water leakaging

  • Ensuring no aircon light blinking

  • Verifying system pressure

  • Checking for aircon error codes

  • Ensuring proper wiring and drainage

  • Testing compressor efficiency

Professionals like LetsCool Aircon and Services Singapore also explain basic maintenance tips and warranty coverage to help extend your aircon’s lifespan.

What Happens After Installation?

Even after your aircon is installed, maintaining it ensures long-term performance.

Recommended Post-Installation Services

  • Aircon general servicing every 2–3 months

  • Aircon steam wash for eco-friendly deep cleaning

  • Aircon chemical wash when there is moderate dirt buildup

  • Aircon chemical overhaul for severe blockages or mold

  • Aircon compressor servicing when the system is not cooling efficiently

To save cost, many homeowners choose an aircon service contract for regular maintenance.
