Question 1

What does "system 3" mean in an aircon installation package?

Accepted Answer

System 3 refers to three indoor units connected to one outdoor compressor, commonly used to cool the living room and two bedrooms in a typical 4-room BTO flat. The number refers to the count of indoor units, not the horsepower or cooling capacity.

Question 2

Is an inverter aircon package worth the extra cost?

Accepted Answer

For rooms used for several hours daily, such as the living room and master bedroom, an inverter system is generally considered more energy-efficient over continuous use compared to non-inverter equivalents, though it typically comes at a higher upfront package price. For lightly used spare rooms, some homeowners still opt for non-inverter units to manage costs.

Question 3

How much does a system 3 aircon package cost in Singapore?

Accepted Answer

Indicative market ranges for a system 3 aircon package are roughly $1,900 to $2,700 for non-inverter setups and $2,400 to $3,400 for inverter setups, though actual pricing varies by brand, BTU capacity, and installation complexity — always confirm with a formal quotation from your chosen aircon supplier.

Question 4

What is R32 refrigerant and why does it matter?

Accepted Answer

R32 is a refrigerant commonly used in newer aircon systems in Singapore, generally understood to have a lower environmental impact than older refrigerants like R410A. It is mildly flammable, so installers should be properly trained in R32-specific safety and installation practices.

Question 5

What should be included in a proper aircon quotation?

Accepted Answer

A proper quotation should itemise the brand and model of each indoor and outdoor unit, BTU capacity, included copper piping length and price per additional metre, copper pipe thickness, trunking type, outdoor unit brackets, drainage routing, and whether GST is included.

Question 6

How long is the warranty on an aircon installation package?

Accepted Answer

Warranty terms vary by brand and vendor, but compressor warranties commonly range from around 3 to 5 years, parts warranties may differ, and workmanship/installation warranty from the installer is often separately stated, commonly around 1 to 2 years. Always confirm each warranty layer individually.

Question 7

Can I get an instalment plan for aircon purchases in Singapore?

Accepted Answer

Many aircon suppliers offer instalment plan options, including 0% instalment payment plans tied to certain credit cards or in-house financing. Always check whether there's a processing fee, the minimum tenure and spend requirements, and the early settlement terms before committing.

Question 8

What are common hidden costs in an aircon package?

Accepted Answer

Common hidden costs include charges for copper piping beyond the standard included length, drilling through reinforced concrete, high-floor access surcharges, premiums for concealed ducted systems, additional bracket reinforcement, and GST or processing fees not reflected in the headline price.

Question 9

When should aircon installation happen relative to renovation works?

Accepted Answer

Aircon piping, trunking and drainage are typically installed before the false ceiling is closed and before final painting, while final commissioning of the indoor and outdoor unit bodies is often scheduled toward the later stages of renovation to reduce dust exposure. Engage your aircon supplier early even though installation itself happens later.

Question 10

How often should I service my aircon after installation?

Accepted Answer

General guidance suggests servicing every three to four months for units in heavy daily use, or at least twice a year for lighter usage. A yearly chemical wash is also commonly recommended for units with high usage.

Question 11

Does switching servicing providers affect my warranty?

Accepted Answer

It can, depending on the terms set by your original installer or the manufacturer. Some workmanship warranties require servicing continuity with the original installer or an authorised agent, so check this before switching to an independent servicing company.

Question 12

What's the difference between Daikin, Mitsubishi, Panasonic and Midea aircon packages?

Accepted Answer

Daikin, Mitsubishi and Panasonic are generally regarded as longer-established brands with wide servicing networks in Singapore, often positioned at a higher price point. Midea and other value-tier brands typically offer more competitively priced aircon deals with expanding local servicing support. Always compare specific models, warranty terms, and authorised dealer status rather than brand name alone.

Question 13

How do I know if my quoted piping length is enough?

Accepted Answer

Ask your aircon supplier to confirm the actual distance between each indoor unit and the outdoor compressor based on your floor plan, and compare this against the standard included metreage in the quotation. If the actual distance exceeds the standard allowance, clarify the per-metre charge for the excess before signing.

Question 14

Should I choose a system 4 or system 5 package for a 5-room flat?

Accepted Answer

Most 5-room BTO flats are adequately served by a system 4 package covering the living/dining area and three bedrooms. A system 5 may be considered if you want to cool an additional space such as a store room, household shelter, or a fourth room, or if you're in a maisonette or landed property with more rooms overall.
