Should you sign up for a yearly aircon contract or book one-time servicing whenever your air conditioner needs attention?
A yearly aircon contract is generally more suitable for Singapore households that use multiple aircon units regularly and want scheduled preventive maintenance. One-time servicing can be suitable for occasional aircon users who prefer to book only when required.
The right choice depends on your aircon usage, number of indoor units, preferred servicing frequency and budget. This guide compares both options to help you make an informed decision.
Quick Comparison: Yearly Aircon Contract vs One-Time Service

|---|---|---|
| Servicing schedule | Planned throughout the year | Book whenever required |
| Number of visits | Usually fixed by the package | No fixed number |
| Payment | Annual package payment | Pay for each appointment |
| Price per service | Often lower for eligible packages | Depends on each booking |
| Service reminders | Usually provided | Customer must remember |
| Suitable for | Frequently used aircons | Occasionally used aircons |
| Maintenance approach | Preventive | On-demand |
| Commitment | Usually 12 months | No yearly commitment |

What Is a Yearly Aircon Servicing Contract?
A yearly aircon servicing contract is a maintenance package covering a fixed number of scheduled servicing visits during 12 months.
For example, a quarterly contract normally provides four servicing visits—approximately one visit every three months. The aircon company may contact the customer before each appointment to arrange a suitable servicing date.
A yearly contract normally focuses on general preventive servicing. It does not automatically mean that every repair, replacement part, chemical wash, or gas top-up is included.
Customers should examine the package scope and exclusions before signing up.
Current Letscool Aircon contract prices
Letscool Aircon currently offers four scheduled services per year for eligible residential properties:
| Indoor units | Services per year | Annual price | Price per unit per visit |
|---|---|---|---|
| 2 units | 4 | $160 nett | $20 |
| 3 units | 4 | $240 nett | $20 |
| 4 units | 4 | $288 nett | $18 |
| 5 units | 4 | $360 nett | $18 |
The advertised $18 per unit rate applies to four- and five-unit packages. Prices and package conditions may change, so customers should check the current aircon service contract Singapore page before booking.
Your live service page currently confirms four annual visits and the above 2–5-unit prices.
What Is One-Time Aircon Servicing?
One-time aircon servicing means booking a single service appointment without committing to an annual maintenance package.
The customer contacts the aircon company whenever servicing is needed and pays for that appointment. There is no ongoing schedule, annual payment or requirement to continue using the same company.
One-time servicing is sometimes called:
- One-off aircon servicing
- Ad-hoc aircon servicing
- Single aircon service
- On-demand aircon servicing
Use “one-time” instead of “on-time.” “On-time service” refers to punctuality and does not correctly describe a single servicing appointment.
What Is Normally Included in General Aircon Servicing?
The exact scope varies between companies, but general aircon servicing commonly covers accessible indoor-unit components.
Typical work may include:
- Cleaning reusable air filters
- Cleaning the front panel and air outlet
- Cleaning the accessible cooling-coil surface
- Cleaning the blower area
- Cleaning the drain pan
- Vacuuming or flushing the drainage pipe
- Checking basic electrical connections
- Checking the unit’s operating condition
- Testing cooling performance after servicing
General servicing is preventive maintenance. It may not resolve problems caused by failed components, refrigerant leakage, severe internal contamination, or installation defects.
Services that may be charged separately
Confirm the following exclusions before purchasing a package:
- Aircon chemical wash
- Aircon chemical overhaul
- Refrigerant gas top-up
- Replacement spare parts
- Electrical and mechanical repairs
- Dismantling and reinstallation
- Ceiling access work
- Scaffolding or specialised access equipment
- Commercial or industrial aircon servicing
If the aircon is already leaking, producing unusual noises, or not cooling, it may require inspection or professional aircon repair rather than routine cleaning alone.
Is a Yearly Aircon Contract Cheaper?
A yearly aircon contract can provide a lower price per unit per visit, especially when several indoor units are serviced together. However, the total annual cost depends on how many visits you would otherwise book.
For example, a household with four indoor units under Letscool Aircon’s current quarterly package pays:
Four units × $18 × four visits = $288 nett per year
The contract provides predictable servicing expenses and four planned visits. A household booking only one service during the year may spend less overall, but it will also receive less frequent maintenance.
Therefore, the cheaper option depends on the household’s actual usage:
- Regular daily usage: A yearly contract may provide better maintenance value.
- Occasional usage: One-time servicing may have a lower annual cost.
- Several indoor units: A multi-unit contract may reduce the cost per unit.
- One rarely used unit: An annual package may be unnecessary.
Compare equivalent service scopes when checking prices. A cheaper package may exclude drainage work, condenser cleaning, transport, GST or other items.
Benefits of a Yearly Aircon Contract
1. Regular servicing is easier to remember
Busy homeowners may forget when their aircon was last serviced. A contract creates a planned schedule instead of relying on the customer to remember every appointment.
2. It supports preventive maintenance
Regular servicing helps reduce dirt accumulation on accessible filters, coils, blowers, and drainage components. Technicians can also identify visible warning signs during scheduled visits.
Preventive servicing cannot guarantee that an aircon will never break down, but it can reduce problems caused by neglected cleaning.
3. It provides predictable annual costs
The customer knows the basic general-servicing cost for the contract period. Repairs, replacement parts, and specialised cleaning may still incur additional charges.
4. It is convenient for homes with several units
HDB flats and condominiums may have three, four or five indoor units. A contract makes it easier to maintain all units on the same schedule.
5. It may reduce the price per servicing
Multi-unit packages may offer a lower per-unit rate than separate small bookings. Always calculate the total annual price and confirm how many visits are included.
6. It encourages consistent aircon care
Many people arrange servicing only after the aircon becomes weak, noisy, or starts leaking. A scheduled contract encourages maintenance before these symptoms become disruptive.

Disadvantages of a Yearly Aircon Contract
A servicing contract is not automatically the right choice for every customer.
Possible disadvantages include:
- Upfront or advance payment may be required.
- Unused servicing visits may expire.
- Appointments may need to be completed at one address.
- Chemical cleaning and repairs may not be included.
- Customers may need to provide advance notice when rescheduling.
- The contract may not be transferable after moving home.
- Rarely used aircons may not need quarterly servicing.
Read the contract conditions carefully, particularly the expiry date, cancellation policy, rescheduling rules, and service exclusions.
Benefits of One-Time Aircon Servicing
No annual commitment
Customers can book one appointment without paying for future services.
Suitable for occasional aircon use
A guest-room aircon or a unit used only occasionally may not require the same servicing frequency as a bedroom aircon used every night.
Freedom to compare companies
Customers can choose a different aircon company for each appointment. However, changing technicians regularly may reduce service-history continuity.
Payment only when a service is booked
There is no prepaid package. This can be helpful for customers who are moving soon, renting temporarily, or uncertain about future servicing needs.
Disadvantages of One-Time Servicing
The main disadvantage is the absence of a regular maintenance schedule.
Customers may:
- Forget the previous servicing date
- Wait until cooling performance becomes weak
- Arrange servicing only after water leakage starts
- Pay a higher rate for small or urgent bookings
- Lack a consistent maintenance record
- Have difficulty getting a preferred appointment during busy periods
One-time servicing remains a reasonable option when the aircon is used infrequently, and the homeowner monitors its condition properly.
Which Option Is Better for HDB and Condo Homes?
A yearly aircon contract is usually more practical for an HDB or condominium household that operates bedroom aircons every night and has several indoor units.
Consider a yearly contract if:
- You have three or more indoor units.
- Your household uses aircon almost every day.
- You want servicing approximately every three months.
- You prefer service reminders.
- You want a predictable general-servicing budget.
- You intend to remain at the same address for the contract period.
Consider one-time servicing if:
- You use the aircon infrequently.
- You have only one active indoor unit.
- You may move house soon.
- You do not want to prepay.
- You prefer to arrange maintenance yourself.
How Often Should Aircon Be Serviced in Singapore?
Aircon servicing frequency should be based on operating hours, indoor conditions, and system condition.
As a practical guide:
| Aircon usage | Suggested inspection or servicing frequency |
|---|---|
| Used every night | Approximately every 3–4 months |
| Used occasionally | Approximately every 4–6 months |
| Heavy daily usage | Approximately every 2–3 months |
| Office or commercial use | Based on operating hours and site conditions |
| High-dust environment | More frequently when required |
These are general guidelines rather than fixed rules. Aircons exposed to renovation dust, pets, smoke, or extended operating hours may become dirty faster.
How to Choose a Reliable Aircon Contract
Do not select a contract based only on the lowest advertised price.
Check the following:
Number of visits
Confirm whether the package provides two, three, four, or more visits per year.
Number of covered units
Check whether the price applies to indoor fan-coil units, outdoor condensers, or both.
Exact scope
Ask what technicians clean and inspect during each appointment.
Exclusions
Confirm whether gas top-up, repairs, replacement parts, chemical cleaning, and condenser washing are excluded.
Expiry and rescheduling
Check how much notice is required and whether unused visits expire.
Property restrictions
Confirm whether the price applies to HDB flats, condominiums, landed properties, commercial premises, or all property types.
Company credibility
Review the company’s address, customer feedback, warranty terms, and service documentation before paying.
Yearly Contract or One-Time Service: Final Recommendation
Choose a yearly aircon contract when you use multiple aircon units regularly and want four planned preventive-maintenance visits.
Choose one-time aircon servicing when your unit is rarely used, you do not want an annual commitment, or you only require occasional maintenance.
The best choice is not simply the option with the lowest advertised price. Compare the number of services, price per unit, maintenance scope, exclusions, and contract conditions.

Frequently Asked Questions
Is an aircon servicing contract worth it?
An aircon servicing contract can be worthwhile for households that use several aircon units regularly. It provides scheduled preventive maintenance and may reduce the price per unit per visit. Occasional users may prefer one-time servicing.
How many services are included in a yearly aircon contract?
The number depends on the selected package. A quarterly contract normally includes four services over 12 months. Confirm the number of visits before purchasing.
What is the difference between contract and one-time servicing?
A contract provides a fixed number of scheduled services during an agreed period. One-time servicing is a single appointment without an ongoing maintenance commitment.
Is aircon repair included in a servicing contract?
Routine servicing contracts usually focus on preventive cleaning and basic checks. Repairs, replacement parts, and specialised work may be charged separately. Check the package terms.
Does an aircon contract include chemical washing?
Chemical washing is commonly treated as a separate deep-cleaning service. Confirm the inclusions because package conditions vary between aircon companies.
Is gas top-up included in an annual contract?
Refrigerant top-up may be excluded or separately charged. Customers should obtain written confirmation of the refrigerant type, quantity, and additional cost before approving a top-up.
Can I transfer my contract when I move house?
Transfer conditions depend on the aircon company’s terms. Some contracts are limited to the original address, units, or customer. Check this before signing up if you expect to move.
Is quarterly aircon servicing necessary?
Quarterly servicing can be suitable for aircons used regularly. Units used occasionally may require less frequent servicing, while heavily used commercial units may require more frequent maintenance.
