What we do
- Split AC cleaning & maintenance
- Advice on your AC's condition and servicing needs
- If we find something that needs repair, we explain first before doing anything
Musty smell, weak airflow, or not cleaned in ages? A proper clean keeps your AC running clean.
After running for a long time, dust and moisture build up beyond the filter, in places you normally can't see. Willson cleans and services ACs, planning the work around the model and where it's installed. Before booking, feel free to tell us how your AC is doing.

Every AC is used differently, so before cleaning we find out:
Wall-mounted split ACs are the most common. How many units and which rooms they're in affects scheduling.
Furniture and appliances under and beside the indoor unit need to be moved so they don't get splashed with water or dirt.
Tell us about any musty smell, weak airflow, dripping or noise. If it sounds more like a fault, we'll check it as an AC repair instead.
The method differs for outdoor units on a balcony, a platform or an outside wall. Never climb out to clean a wall-mounted unit yourself.
For filter cleaning and pre-season test runs you can do yourself, see AC maintenance tips中文. For outdoor units near the sea, see the rust advice in Local notes for Dayuan中文.
Tell us the brand, number of units and current condition.
We explain the cost, then set a time to come.
Work done according to the model and installation position.
We tell you how it went; if we found anything needing repair, we explain it first.
Actual steps depend on the job. For details, see How it works.
There's no fixed answer — it depends on how much you use it, how dusty the room is and whether you have pets. You can clean the filter yourself regularly; if it still smells musty or the airflow is weak after that, or the indoor unit hasn't been cleaned in a long time, it's time to book a clean. For everyday care, see AC maintenance tips中文.
Filter cleaning is routine care you can do yourself. Dirt deep in the heat exchanger, fan and drain pan needs tools and experience — and water must be kept out of the electrical parts — so we recommend leaving that to a professional.
Tell us the brand, number of units, where they're installed (which room the indoor unit is in, where the outdoor unit is) and the current condition — for example a musty smell, weak airflow or dripping.
If we find something that needs repair, we explain it to you first and only fix it once you agree. For AC faults, see AC repair.
It depends on the model, installation position, pipe length and site, so we don't give prices on the website. Please call 0953 144 721 and we'll explain for your situation.

AC on but not cooling? First check the mode, temperature setting, filter and outdoor unit ventilation, then see whether it's a refrigerant, parts or capacity problem that needs a pro.

Common reasons for a dripping indoor unit: a blocked drain pipe, not enough drain slope, a very dirty filter, poor insulation or a unit that isn't level.
