Aircon installation in Singapore

Assess the space and cooling needs

Room dimensions, ceiling height, sunlight, glazing, occupancy, heat-producing equipment and insulation all affect cooling load. A site assessment helps determine capacity and which rooms need cooling at the same time. Oversizing and undersizing can both cause problems.

Choose a suitable system

Compare the capacity range, noise, controls, maintenance access and local energy-efficiency labels of suitable models. For multi-split systems, check how indoor units share the outdoor unit's capacity.

Evaporative coolers add moisture and are not equivalent to refrigerant air conditioning; Singapore's humid conditions limit their usefulness. Equipment life and electricity costs depend on the model, installation, use and maintenance—not a guaranteed lifespan or savings percentage.

Plan the installation

• Confirm indoor and outdoor locations, maintenance clearances and safe access.
• Check appropriate electrical supply, refrigerant pipe routes, insulation and condensate drainage.
• For ductless split systems, plan refrigerant piping and drains; these are not air-distribution ducts. Ducted systems need a separate duct design.
• Confirm any relevant building-management, HDB or other approval requirements before work.
• Agree suitable leak checks, evacuation, commissioning and drainage checks for the equipment.

Get a clear quotation

Provide the property type, rooms to be cooled, existing equipment and any access constraints. Ask the quote to identify the proposed models and capacity, included installation materials, removal work, electrical work, access charges, applicable tax and workmanship/manufacturer warranty terms.

Check payment timing and the appointment arrangements before accepting. Do not assume every installation includes the same materials or extras.
