Why This Product Matters

Dirty indoor coils crush efficiency and kick up smells. This non-rinse formula brings back clean fins and smoother airflow without hauling in hoses. Last week in a steamy Brisbane townhouse, we hit a musty split-system: covers off, spray on, short dwell, back together — customer reckoned the air felt “brand new” and the sneezes stopped. That’s less time on site and fewer call-backs — no dramas.

Pro Tip

Kill power, pull the filters and shroud, then spray coils from top to bottom. Give it a short dwell so the surfactants can work through the fins before reassembly. Pair with a cleaning bib if you expect heavy run-off.
