What We Do

Is Your Aircon Telling You It Needs a Chemical Wash?

Most aircon issues come from dirty coils and blocked drains — not broken parts. A chemical wash fixes both.

Water dripping inside

Common Questions

How is a chemical wash different from regular servicing?

Regular servicing rinses the filters and coils with water. Chemical wash uses a foaming chemical solution that breaks down mould, bacteria, and mineral deposits that water alone can't remove. It also includes cleaning the fan barrel and drain pan — parts that general service skips.

Is the chemical safe for my family and pets?

Yes. We use a food-grade, biodegradable chemical solution. After application and rinse, no chemical residue remains in the unit. We recommend waiting 30 minutes after the job is done before using the aircon, just to be safe.

My aircon still smells bad after a general service. Will chemical wash fix it?

Almost certainly yes. Persistent musty or sour smells are caused by mould and bacteria on the fan barrel and coil — areas that regular servicing doesn't reach. Chemical wash eliminates these at the source. If the smell persists after a chemical wash, we'll diagnose it under our 60-day warranty at no extra cost.

How often should I get a chemical wash?

Once a year is enough for most homes if you do regular servicing every 3 months. If you live in a high-humidity area, cook a lot, or have pets, every 6–8 months is better. Commercial spaces should do it every 6 months.

Do I need to be home during the service?

Yes, someone should be present to let our technician in and confirm the job is done to your satisfaction before we leave. The job takes 90–120 minutes per unit, so plan for that time window.

"Had 4 units serviced at my condo. They gave me multi-unit pricing without me even asking. Technician was polite, wore shoe covers, and cleaned up after."

"My office aircon was barely cooling. Smart Fix diagnosed a gas leak, fixed it, and did a top-up the same day. Office feels brand new now. Thank you!"
