AC Cleaning
Bangkok dust and humidity clog an evaporator coil in about six months. One proper wash restores the cold, the airflow and the power bill — and we show you the numbers.
Noticing any of these?
You don't need to diagnose it — that's our job. Send a photo or a short video on LINE or WhatsApp and a technician will tell you what you're dealing with before you book.

- Not as cold as it used to be, or takes forever to cool the room
- Weak airflow from the vent even on high fan
- A musty smell when it starts up
- Water dripping from the indoor unit or along the wall
- Electricity bill creeping up with no change in use
The CoolRova protocol
Isolate & bag
Power isolated at the breaker, cover and filter off, the unit sealed inside a wash bag that drains to a bucket — drop sheet on the floor.
Coil & blower wash
Biodegradable foaming coil cleaner, then a low-pressure wash through the evaporator fins and blower wheel until the water runs clear.
Drain flush & test
The condensate line is flushed and tested with water so the drip you'd get in three weeks doesn't happen.
Measure & report
Reassembled, run, and the supply-air temperature and gas pressure logged. Before and after photos sent on LINE before we leave.

How long does it take?+
About 45 minutes per wall-mounted unit, including photos and readings. Three units is a comfortable two-hour visit.
Do I need to do anything before you arrive?+
Just clear a metre or so under the unit. We bring drop sheets, ladders and everything else and leave the room exactly as we found it.
Will you check the gas?+
Yes — a pressure reading is part of every clean and goes in your report. If it's low, we'll tell you it's a leak and quote the fix rather than topping up blindly.
