How Often Should You Service Your Air Conditioner?

Intro

In Singapore’s hot and humid climate, air conditioners work hard year-round. Regular servicing is crucial to maintain efficiency, prevent breakdowns, and save on energy bills. But how often is really necessary?

At Cool & Clean SG, we recommend the following servicing schedule based on usage, unit type, and environmental factors.

1. Standard Aircon Servicing Frequency

For Residential Units (HDB/Condo):

✔ Every 3 Months – Basic cleaning (filter wash, coil check)
✔ Every 6 Months – Chemical cleaning (deep wash for bacteria/mold)
✔ Annually – Full chemical overhaul (gas top-up, full inspection)

Why? Dust, humidity, and constant usage clog filters and reduce efficiency.

For Commercial Units (Offices/Shops):

✔ Monthly – Filter cleaning (high usage)
✔ Quarterly – Chemical wash (prevents bacteria buildup)

2. Factors That Affect Servicing Frequency

A. Usage Duration

• Daily (8+ hours): Service every 2-3 months

• Occasional (Weekends only): Every 6 months

B. Type of Aircon

• Split Units: Every 3-6 months

• Window Units: Every 4-6 months (easier maintenance)

• Centralized Systems: Monthly checks for large spaces

C. Environmental Factors

• Near Construction Sites: More dust → Service every 2 months

• Coastal Areas: Salt corrosion → Check every 3 months

• Pet Owners: Hair/clogging → Clean filters monthly

3. Signs You’re Overdue for Servicing

Watch for these warning signals:
🔹 Weak airflow (clogged filters)
🔹 Unusual noises (grinding, squeaking)
🔹 Musty smells (mold in ducts)
🔹 Water leaks (drain pipe blockage)
🔹 High electricity bills (overworking unit)

 Ignoring these can lead to:

• 60% higher energy consumption

• Costly compressor repairs

• Health risks (mold/allergies)

4. What’s Included in Professional Aircon Servicing?
