General vs Overhaul Aircond Cleaning – Which One Do You Need?
Introduction
So your aircond isn’t cooling as it used to. Maybe it smells funky or even leaks water now and then. You’ve searched online and found two types of cleaning services: General Cleaning and Overhaul Cleaning. But which one do you actually need?
Don’t worry—we’ve got you covered. In this guide, we’ll break down the difference between general and overhaul aircond cleaning, so you can make the right choice and avoid wasting money on the wrong service.
Why Aircond Cleaning Matters in Malaysia
In hot and humid places like KL and Selangor, your aircond works hard almost every day. This causes dust buildup, mold growth, and wear and tear faster than in cooler climates. Regular cleaning is a must—not just for comfort, but for your health and your electricity bill.
What Is General Aircond Cleaning?
What It Includes
- Filter cleaning
- Fan coil wiping
- Drain pipe flushing
- Surface dirt removal
- Basic performance check
When It’s Recommended
- Every 3–6 months for residential units
- If your AC is still cooling well
- As routine maintenance
Ideal Frequency
General cleaning is recommended twice a year, or more often if you use your unit daily.

What Is Overhaul Aircond Cleaning?
What It Includes
- Full dismantling of indoor unit
- Deep cleaning of evaporator coil
- Chemical flushing
- Mold and odor removal

If more than one answer is “yes” to problems → go for overhaul.
What Technicians Look For
Pros check the blower, coil, filters, and drain. They’ll recommend the right service based on actual condition—not guesswork.
What Happens During Each Type of Cleaning?
Tools and Processes Used

Is It Worth Paying More?
If your aircond hasn’t had a deep clean in over a year, then yes—it’s absolutely worth it. It can make your old unit feel new again.
Mistakes to Avoid When Choosing a Cleaning Service
Choosing Cheapest Option
Cheaper isn’t always better. Inexperienced cleaners may skip crucial steps or damage components.
Not Asking for Before/After Checks
Always ask for before/after photos or video—especially for overhaul services.
Conclusion
Knowing the difference between general and overhaul aircond cleaning can save you time, money, and headaches. If you just need routine maintenance, general cleaning does the job. But if your unit is smelly, leaking, or not cooling properly—it’s time for an overhaul.
Whether you’re in KL, Selangor, or anywhere humid and hot in Malaysia, regular maintenance is the key to clean air, cool rooms, and low electricity bills.
Don’t guess. Ask your technician. Choose wisely. Stay cool.
