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.

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.

These rules come from HDB’s official renovation guidelines for air conditioner installation works. Non-compliance can result in mandatory rectification at your own cost.

System 3 and System 4 are the two most popular aircon configurations in Singapore homes. Both use a single outdoor condensing unit to serve multiple indoor fan coil units. The difference is how many indoor units the system supports. But that one-unit difference affects cost, cooling capacity, outdoor unit size, and electricity consumption. This guide […]
Copper piping is the connection between your indoor and outdoor aircon units. It carries refrigerant in both liquid and gas form, and its condition directly affects how well your system cools. When piping fails, the result is a slow refrigerant leak that gets worse over time, costing you in repeated gas top-ups and declining performance […]
