For any Singaporean homeowner, installing a new air-conditioner is a major decision. The perpetual heat and humidity make it a necessity, but the process can be stressful. You’re faced with confusing quotations, the fear of hidden costs, and stories from friends about shoddy workmanship that leads to years of leaks and problems.
The core dilemma isn’t just “how much does an aircon cost,” but “how much should a good aircon installation cost?” A cheap price tag today can easily become a major headache tomorrow.
At Vedha, we believe in 100% transparency. This guide will break down the real costs of a new aircon installation in 2025. We’ll show you exactly what you’re paying for, so you can invest wisely in a reliable system that brings you cool comfort for years to come.
The Anatomy of Your Quote: What Are You Paying For?
A professional and honest quotation should clearly itemize every component. Here’s what to look for:
1. The Aircon Unit Itself This is the largest single expense. The price depends on the brand, the system type (how many indoor units), and its cooling power (BTU). For a popular 5-tick, System 3 multi-split from trusted brands like Mitsubishi Electric or Daikin, expect the unit alone to cost between S2,600andS3,600.
2. Installation Labour This cost varies based on the complexity of the job. A brand new BTO flat is the most straightforward. A resale flat is more complex as it requires dismantling the old system. Condominiums are often the most challenging due to strict MCST rules on working hours and access.
3. The Most Important Factor: Installation Materials This is where cheap installers cut corners, leading to future problems. A quality installation is defined by the materials used. Always insist on upgraded materials—the small extra cost is the best investment you can make.
| Material | Standard Grade | Upgraded Grade (Recommended) | Why It’s Worth It |
| Copper Pipes | SWG 23 Thickness | SWG 22 Thickness | Thicker pipes are far more durable and less likely to develop gas leaks over time, saving you from expensive future repairs. |
| Insulation | 3/8-inch Thickness | 1/2-inch Armaflex | In Singapore’s humidity, thicker insulation is the best defence against condensation (“sweating”) and water damage on your walls. |
| Drainage Pipe | 13mm Diameter | 16mm Diameter | A wider pipe is less likely to clog with slime, which is the #1 cause of water leaking from the indoor unit. |
4. Optional (But Common) Charges
- Stainless Steel Bracket: Needed for older HDB flats without an AC ledge. Cost is around S$150.
- New Power Point: If your flat lacks a dedicated power point, installation by a licensed electrician can cost S150−S245.
Real-World Scenarios: How Much for My Home?
To make it clearer, here are two sample quotations for common scenarios.
Case Study 1: System 3 in a New 4-Room BTO A young couple needs a reliable, 5-tick system for their new home. They choose a popular Mitsubishi Starmex System 3.
| Item | Estimated Cost (S$) |
| Mitsubishi Starmex System 3 Unit | 3,285 |
| Installation Labour (New HDB) | 450 |
| Upgraded Materials Included | – |
| GST (9%) | 336 |
| Total Estimated Cost | ~S$4,071 |
Case Study 2: System 2 in a 2-Bed Condo A property owner wants a quiet and durable Daikin System 2 for a rental unit.
| Item | Estimated Cost (S$) |
| Daikin iSmileEco+ System 2 Unit | 2,100 |
| Installation Labour (Condo) | 550 |
| Upgraded Materials Included | – |
| GST (9%) | 239 |
| Total Estimated Cost | ~S$2,889 |
The higher labour cost for the condo reflects the extra complexity of working within MCST rules.
A Technician’s #1 Tip: Don’t Fall for the “Cheap” Trap
A quote that seems too good to be true usually is. An installer offering a rock-bottom price is almost certainly using inferior, standard-grade materials. That S300 you “save” today will be wiped out by a S500 repair bill for a leaking pipe next year.
A cheap installation is a headache waiting to happen. The Total Cost of Ownership—the initial price plus future repair and electricity costs—will always be higher. Investing a little more upfront for a professional installation with high-quality materials is the smartest financial decision.
