DIY vs Professional Aircon Cleaning: What's the Difference?

Should you clean your aircon yourself or hire a professional? Here's exactly what each covers and when it's worth paying.

The DIY Option Is Real — But Limited

You can and should clean your aircon filters yourself every month. It takes 10 minutes and keeps airflow good between professional cleanings.

Here's what you can safely DIY:

DIY-safe tasks:

Remove and rinse the front filters under running water
Wipe down the outer casing
Clear any visible debris from around the outdoor unit

That's mostly it. Everything deeper requires partial disassembly.

What a Professional Cleaning Covers

When a GoClean technician comes for a cleaning, here's what actually gets done:

1. Full filter cleaning — same as DIY, but also inspecting for damage

2. Evaporator coil cleaning — the aluminum fins inside the unit. Dirt on these fins insulates them, dramatically reducing cooling. Requires high-pressure water or chemical coil cleaner.

3. Blower fan cleaning — this is the part most technicians skip. The plastic fan wheel accumulates a thick layer of dust and mold that doesn't come off without disassembly. A dirty blower is the #1 cause of musty smells.

4. Drain pan and drain line flushing — the pan collects condensate; the line drains it outside. A blocked drain causes water leaks inside your room and grows mold.

5. Outdoor unit (condenser) cleaning — the coils outside get clogged with dust, leaves, and debris, especially near roads or in areas with trees.

6. Refrigerant pressure check — not cleaning, but caught during the visit. Low pressure is an early warning of a leak before it causes bigger problems.

The Chemical Overhaul Option

For units that haven't been cleaned in over a year, a standard cleaning isn't enough. A chemical overhaul uses a chemical solution to dissolve buildup that water pressure can't remove. It costs more (₱1,200–₱2,000) but restores the unit closer to new condition.
