What is an aircon maintenance contract?
Our aircon annual maintenance contract books four general servicing visits a year, about one every three months. You never have to keep track of dates or call to book. It is quarterly servicing on a schedule, with priority booking if something goes wrong between visits.
Each visit is the full 8-point service, the same one you get from a single booking. The only difference is that it’s planned ahead and priced lower over the year.
| Indoor unit | Checks and tests |
|---|---|
| Air filter cleaning | Refrigerant pressure check |
| Evaporator coil check and clean | Thermostat test |
| Drain line flush | Electrical check |
| Drain pan check | Airflow and temperature test |
How much does a contract save?
The contract starts from S$200 a year for 2 units. Four single visits for the same 2 units cost S$220, at S$55 each. At that starting size, the contract works out S$20 cheaper.
| Option (2 units) | Visits per year | Yearly cost |
|---|---|---|
| Annual maintenance contract | 4 | From S$200 |
| Four single bookings at S$55 | 4 | S$220 |
Got 3 or 4 units? We quote by unit count, so the price fits your flat. Full prices for every service are on the price list.
Why does a regular schedule matter in Singapore?
Singapore is hot and humid all year. According to the Meteorological Service Singapore, the mean annual relative humidity is around 82%, and it often tops 90% just before sunrise. Most units in Ang Mo Kio run through that almost every day.
Here’s what builds up inside your aircon:
- Filters clog with dust and grease.
- Dust settles on the evaporator coil.
- The condensate drain line slowly chokes with slime.
That last one matters most. A 2026 HomeJourney guide on aircon leaks in Singapore lists a clogged condensate drain line as the most common cause of dripping water. Leave it for a year and you often end up with a wet wall or a room that never quite gets cold.
Servicing every 3 to 4 months keeps cooling steady and catches small faults early. Our guide on how often to service your aircon explains the timing.
Who is the contract for?
It suits HDB owners with a few wall-mounted units, and it works well for:
- Homes with 2 to 4 units, or more
- Rental flats that must stay in working order
- Units that keep breaking down
- Anyone who’d rather not track servicing dates
If you have one unit that you use now and then, single general servicing visits may be enough. We’ll tell you so.
Common Problems We Solve
Forgetting to book servicing
Most breakdowns we see start with a unit that went far too long without a service. The contract removes the guesswork. Visits are scheduled for you and confirmed ahead of time.
Repeat breakdowns
If the same unit keeps leaking or losing cooling, regular visits catch a choked drain or dirty coil before it turns into a repair. Sometimes a visit finds a deeper problem, such as heavy mould that needs a chemical wash. In that case, we explain it and quote first.
Rental units that must stay working
Landlords need working units for each tenancy. The contract keeps a service record from every visit, which helps when tenants move in or out. Our guide on servicing before a tenancy handover covers the handover side.
Many units in one home
Landed homes in Yio Chu Kang and Sembawang Hills often have more units, including cassette and ducted units. Condos may run a multi-split System 4. One contract covers them all at a price based on unit count, so you aren’t booking five or six separate visits each quarter.
What does a contract visit look like?
The technician arrives at the agreed time and starts with the units you use most. Here’s how a typical visit runs:
- Each indoor unit has its air filter taken out and washed.
- The evaporator coil is checked and cleaned, and the drain pan is inspected for slime.
- A drain line flush clears the pipe that carries water away from the unit. This is the step that prevents most leaks.
- At the outdoor unit, the refrigerant pressure is checked.
- A thermostat test and electrical check follow.
- Each unit is run and tested for airflow and temperature.
If something isn’t right, you’re told what it is and what it would cost to fix. Examples are a coil that stays dirty after servicing, or a pressure reading that suggests a leak. Nothing extra is done without your go-ahead.
The visit is then logged as a service record. You can see when each unit was last serviced and what was found.
What if you move or need to pause?
Tell us early. Visits can be moved around holidays or renovation work. If you move to another home in Ang Mo Kio, the schedule can follow you.
