From $150/unit

A chemical overhaul is the most thorough clean your aircon can get. We take the fan coil off the wall, dismantle it, and soak the coil, blower, tray and casing in a chemical solution before rinsing, drying and reassembling everything.

It is the best option for units that have not been serviced in years, units with heavy mould growth, or systems that are noisy and leaking despite regular cleaning. In many cases an overhaul brings an older unit back to near-original performance — at a fraction of the cost of replacement.
