1. Assess Your Home Layout and Cooling Needs


Before installing an aircon, start by evaluating your home’s layout, room sizes, and usage patterns. Different rooms require different cooling capacities, and choosing the wrong system can lead to inefficiency or frequent breakdowns.

For example, bedrooms usually require less cooling compared to living rooms. Ceiling height, sunlight exposure, and insulation also affect performance. A professional assessment by Letscool Aircon and Services Singapore ensures the correct BTU rating is selected, preventing future problems such as aircon not cold or high electricity bills.

This is also the right time to consider future maintenance. Homes with multiple units may benefit from an aircon service contract, which covers routine aircon servicing Singapore and reduces long-term costs.

2. Choose the Right Aircon System and Brand


Singapore homeowners typically choose between single-split, multi-split, or system aircons. Each option has its pros and cons depending on budget, space, and cooling requirements.

  • Single-split systems are ideal for individual rooms.


  • Multi-split systems allow multiple indoor units connected to one outdoor unit, saving space.


  • System aircons are suitable for larger homes or families needing consistent cooling.



Beyond system type, brand reliability and availability of aircon spare parts are crucial. Reliable brands paired with expert installation reduce the risk of issues like aircon error code warnings or frequent aircon repair Singapore calls.

3. Plan the Installation Location Carefully


Correct placement of indoor and outdoor units directly affects aircon efficiency and lifespan. Indoor units should be installed where airflow is unobstructed, while outdoor compressors need proper ventilation to prevent overheating.

Improper placement can cause problems such as aircon water leakage or unusual noises. Professional installers from Letscool Aircon and Services Singapore ensure piping, drainage, and wiring are correctly set up, minimising future repair needs.

This step also includes planning for drainage systems to avoid condensation issues, which are common causes of water leakage in Singapore homes.

4. Ensure Proper Installation and Testing


Quality installation is just as important as choosing the right aircon. Poor workmanship can lead to refrigerant leaks, faulty wiring, or weak cooling performance.

During installation, technicians should:

  • Secure all piping and insulation


  • Check electrical connections


  • Test for refrigerant pressure and perform aircon gas top-up if required


  • Ensure the system runs smoothly without error indicators



After installation, thorough testing helps detect early signs of problems, such as aircon light blinking or unusual performance. This reduces the chances of unexpected breakdowns and costly aircon repair singapore services later.

5. Schedule Post-Installation Servicing and Maintenance


Many homeowners overlook maintenance right after installation, but this step is critical. Regular aircon general servicing keeps your system efficient and prevents common issues.

Depending on usage, services may include:

For older or heavily used systems, an aircon chemical overhaul may be recommended to restore cooling efficiency. Signing up for the best aircon servicing Singapore packages or a long-term service contract ensures your system remains in top condition year-round.

Look Out for Promotions and Long-Term Value


Aircon installation is an investment, so it’s wise to look for value-added services and aircon promotion deals. Reputable companies often bundle installation with servicing packages, offering better long-term savings.
