High Pressure Chemical Cleaning

Musty air. Weak cooling. It's what's inside.

Rinsing the filter only cleans the surface. The real build-up sits deep in the coil and blower. We open the unit and flush it out with chemical and high pressure water — so you get clean, properly cold air back today.

Common questions

How long does it take?

Around an hour per wall-mounted unit, depending on how dirty it is and where it's installed.

Will it make a mess?

No. The wash bag wraps the unit and channels the dirty water into a bucket, and we cover the floor before we start.

Is the chemical safe?

Yes. It's completely rinsed out with high pressure water before the aircon is switched back on.

How often should I book it?

For bedrooms used every night, most households do it every 6 months.
