AC Services for Homes & Small Offices in Colombo: What to Service, When, and How Much

Stay cool, save money, and extend your AC’s life with the right service schedule.

Why AC Servicing in Colombo Matters

Colombo’s tropical climate means air conditioners work almost year-round, especially in homes, small offices, and retail spaces. While many owners wait until cooling performance drops or units make strange noises, regular servicing is far cheaper than emergency repairs.

A well-maintained AC:

Cools faster & more evenly

Uses less electricity (lower CEB bills)

Lasts longer before needing costly part replacements

Improves indoor air quality, reducing dust, mould, and allergens

What Should Be Serviced in Your AC?

A professional AC service covers more than just “washing the filters.” In Colombo’s dusty and humid environment, these are the main tasks to include:

Service Task    Purpose            Recommended Frequency

Filter Cleaning / Replacement             Improves airflow & cooling efficiency          Monthly (clean) / Annually (replace if needed)

Indoor Unit Coil Cleaning        Removes dust buildup for better heat exchange         Every 6 months

Outdoor Unit Coil Cleaning    Prevents overheating & compressor strain   Every 6 months

Drain Line Flushing     Avoids water leakage & mould growth              Every 6–12 months

Refrigerant Gas Check / Top-up          Ensures optimal cooling & prevents compressor wear   Annually (or when cooling drops)

Electrical & Safety Check        Detects wiring faults before breakdowns    Annually

Fan & Motor Lubrication        Keeps the system running smoothly & quietly Annually

How Often Should You Service Your AC in Colombo?

Home Use (Light–Moderate) – Every 6 months for deep cleaning, with filter cleaning every 1–2 months.

Small Office / Continuous Use – Every 3–4 months, as systems run longer hours and gather more dust.

Near Coastal Areas – Every 3 months, to prevent salt corrosion on coils and outdoor units.
