Aircon servicing frequency in Singapore

If you live in Singapore, you probably run your aircon almost every day. With high humidity and constant heat, it's not a luxury. It's a necessity. But how often should you service it to keep it working well?

The Ideal Aircon Servicing Frequency in Singapore

Most experts recommend servicing your aircon every 3 to 4 months. If you live in an HDB flat or condo and use your aircon daily, quarterly servicing helps maintain performance and prevent breakdowns. For light use, every 6 months may be enough.

"Regular maintenance improves efficiency by up to 15% and reduces breakdown risk." – BCA Green Mark Guidelines (2024)

Why Regular Aircon Servicing Matters

Skipping maintenance shortens your unit’s lifespan. It also leads to problems like:

• Poor cooling

• Water leaking

• Higher electricity bills

• Mould or foul smells

In Singapore, dust and moisture build up quickly inside indoor and outdoor units. Without cleaning, the system clogs and struggles.

Recommended Servicing Schedule Based on Usage

Usage Frequency	Recommended Service Interval
Daily (8+ hrs/day)	Every 3 months
Moderate (3-6 hrs/day)	Every 4 months
Light (<3 hrs/day)	Every 6 months
Rare (guest room)	Once a year

You can also check your aircon service contract. Most companies in Singapore, including ours, offer flexible packages based on these cycles.

HDB and Condo Residents – What to Watch For

If you live in an HDB flat, especially with older systems, quarterly servicing helps prevent leakage that could damage floors or walls. Condo residents should check with the management before booking as some MCSTs restrict outdoor unit access.

What Each Service Should Cover

A basic aircon servicing usually includes:

• Cleaning the filter and cover

• Vacuuming drainage pipes

• Checking gas levels

• Inspecting parts for wear

If you notice weak airflow or noise, you may need chemical cleaning or even a chemical overhaul. These are deeper services done less often, around once every 12–18 months.

Signs You’re Overdue for Servicing

Look out for:

• Air not cold

• Leaking water

• Bad smell

• Loud noises

• Increased electricity bills

These are not normal. They’re signs your aircon needs attention.

Cost of Not Servicing

Servicing might cost $40–$80 per unit, but repairs can hit $150–$300. Compressor damage? That’s $600+. Servicing is cheaper than repair. Always.

Final Tip – Stick to a Schedule

Set reminders. Use your phone calendar. Or better, sign up for a yearly servicing plan. It saves you time and keeps your aircon running smoothly.

FAQ

Q1: Is servicing really needed every 3 months?

Yes, especially in Singapore’s climate. Dust, humidity, and daily use wear out your unit fast.

Q2: What happens if I don’t service my aircon?

You risk gas leaks, breakdowns, mould, and higher bills.

Q3: Can I clean the aircon myself?

You can clean filters, but internal parts need a technician.

Q4: Is chemical cleaning necessary?

Not always. Only when basic servicing can’t solve cooling or smell problems.

Q5: How long does one servicing session take?

Usually 30–45 minutes per unit.

Q6: Do I need to service the outdoor unit?

Yes. Outdoor units gather dirt and affect performance. At least once or twice a year.
