Aircon Chemical Overhaul
A chemical overhaul is the most comprehensive aircon service we offer, and the one most Singapore homeowners wait too long to book. Unlike a standard chemical wash, which cleans the coil while the unit stays mounted, an overhaul means the entire indoor unit comes apart. The blower wheel, fan motor, casing, and every internal component are removed, individually cleaned with chemical solution, then reassembled and tested. If your unit is more than 2-3 years past its last deep clean, has a persistent musty smell that survived a regular wash, or is rattling louder than it used to, this is usually the fix — often for a fraction of what replacement would cost.

Common Questions
No — a chemical overhaul is significantly more thorough. In a wash, we clean the coil in-place without removing the unit from the wall. In an overhaul, we completely dismantle the unit, remove the blower wheel, and clean every internal component separately before reassembly.
About 90 minutes to 2 hours per unit. We recommend scheduling a morning slot so the unit can be tested and cooled down before the evening, especially if you have multiple units being serviced in one visit.
For most units under 8–10 years old that are structurally sound, a chemical overhaul can restore performance significantly at a fraction of the cost of replacement. Our technician will advise honestly on-site if replacement makes more sense instead of pushing an overhaul that won't solve the underlying issue.
Labour, chemical solution, and all standard cleaning work described above. Gas top-up (if needed) and any part replacements are quoted separately and only carried out with your approval first — no surprise charges after the job is done.
Most HDB and condo households in Singapore need one every 2-3 years if they're doing regular servicing and chemical washes in between. If your unit hasn't had a proper overhaul in 4+ years, or you're not sure when the last one was, it's worth booking one now before a small issue becomes a costly repair.
In most cases, yes. Leaking is commonly caused by a clogged or damaged drain pan, blocked drainage, or a dirty blower wheel throwing water off-course. Since an overhaul cleans and inspects all of these directly, it resolves the majority of leak complaints we see.
