If you use your aircon every day in Singapore, you already know it needs regular servicing. The question is whether to book each visit individually or sign up for an annual maintenance contract that handles everything on a fixed schedule. This guide breaks down exactly what a contract includes, how much it costs, and how to decide whether it is the right option for your property.
A standard residential aircon maintenance contract in Singapore includes scheduled professional service visits at agreed intervals, typically quarterly. Each visit covers a full service checklist:
The contract also includes scheduling handled by the service provider (we send reminders and pre-book your slots), priority booking over ad-hoc customers, and a consistent service standard across every visit.
What is NOT usually included: chemical wash, chemical overhaul, parts replacement, and gas top-up. These are separate services priced individually if needed during a scheduled visit.
| Contract Type | Visits Per Year | Number of Units | Approx. Annual Cost | Best For |
| Tri-Year (X3) | 3 | 1 Unit 2 Units 3 Units 4 Units 5 Units 6 Units | From $120 From $150 From $207 From $252 From $300 From $342 | Lighter-use homes or specific commercial contracts |
| Quarterly (X4) | 4 | 1 Unit 2 Units 3 Units 4 Units 5 Units 6 Units | From $152 From $192 From $264 From $320 From $380 From $432 | Standard, daily-use residential homes |
| Bi-monthly (X6) | 6 | Multi-unit | Quote on request | Heavy use or dusty environments |
| Monthly (X12) | 12 | Multi-unit | Quote on request | Commercial properties, F&B establishments |
| Custom Commercial | As agreed | Large systems | Quote on request | Large offices, industrial spaces |
All prices include GST. Multi-unit homes receive package pricing. Final costs depend on the number of units, system type and property access requirements.
| Annual Contract | Ad-Hoc Booking | |
| Cost per visit | 10 to 25 percent cheaper than ad-hoc rates | Standard per-visit pricing |
| Scheduling | We handle it and send reminders | You book and track each visit yourself |
| Priority | Contract clients get scheduling priority | Subject to availability when you call |
| Consistency | Same scope, same standards, same records | May vary between visits and technicians |
| Best for | Daily-use homes and businesses | Holiday homes, investment properties, occasional use |
The honest answer depends on how much you use your aircon.
If your aircon runs daily (which is most Singapore homes), a contract is almost always worth it. You save money per visit, you never miss a service interval, and early-stage issues get caught before they become expensive repairs. The cost of one skipped service that leads to a blocked drain and a $200 repair easily exceeds the annual contract price.
If you have a property that sits empty most of the year, or a guest room that gets used a few times a month, ad-hoc servicing every 6 to 12 months is more practical.

A contract provides scheduled visits at a fixed annual rate with priority booking and consistent service records. Ad-hoc servicing means you book and pay for each visit separately, with no guaranteed slots or pricing.
No. A standard maintenance contract covers general servicing visits. Chemical wash, chemical overhaul, repairs and parts replacement are separate services. If our technician identifies the need for a deeper clean or repair during a scheduled visit, we advise you and provide a separate quote before proceeding.

If your aircon still smells musty, blows warm air, or leaks water after a standard service, the next step is either a chemical wash or a chemical overhaul. Both go deeper than routine servicing, but they are not the same thing and they are not interchangeable. Choosing the wrong one means either paying more than […]
Getting a new aircon installed in Singapore is not complicated, but there is a lot that can go wrong if you choose the wrong contractor or go into the process without knowing what to expect. Prices between contractors vary by thousands of dollars for the same job. In HDB flats, the rules around installation are […]
Table of Contents Singapore runs on air conditioning. With temperatures averaging 31 to 34 degrees Celsius year-round and humidity that regularly tops 80 percent, most homes run their aircon 8 to 12 hours a day without pause. At that kind of usage rate, regular aircon maintenance is not optional. It is the most cost-effective […]
