The flat rate is RM180 to RM220 per unit and includes a complimentary refrigerant gas top-up and a 7-day follow-up check. - Full dismantling of the indoor unit - Each component washed and treated individually - Blower wheel, coil and drain pan deep clean - Complimentary refrigerant gas top-up - Reassembly, test run and 7-day follow-up ![Technician removing the blower wheel during a full overhaul](/images/content/technician-removing-blower-wheel-from-wall-mounted.webp) Technician removing the blower wheel during a full overhaul ## What Is a Complete Aircon Overhaul? Are you searching for a reliable aircon overhaul KL service because your bedroom feels warm even when the AC is blasting? We hear this complaint from Klang Valley homeowners every single week. Fixing it usually requires our deepest cleaning service. Our complete overhaul goes far beyond a standard chemical wash [/aircon-chemical-wash/ →](/aircon-chemical-wash/) , which only cleans the components while they stay mounted on the wall. Taking the indoor unit completely apart reveals the hidden grime. We carefully remove the front cover, louvres, filters, and the drain pan. Removing the blower wheel is the absolute secret to restoring your unit’s cooling power. ### The Deep Cleaning Process The dirty parts go straight into a component soaking bath. We usually set up large plastic tubs right on your porch or bathroom floor to contain the mess. A strong cleaning solution loosens years of dust, mould, and pet dander. We thoroughly scrub every single piece, rinse it clean, and leave it to drain. Meanwhile, the bare evaporator coil still on the wall gets some much-needed attention. Our technicians use a high-pressure jet wash to flush dirt directly into a secure catchment bag. In our humid Malaysian climate, a jelly-like biofilm often clogs the condensation drainage line. We see this slimy bacteria buildup in almost every neglected Daikin and Panasonic unit across Kuala Lumpur. Clearing this specific line prevents those annoying indoor water leaks. ### Reassembly and Testing Our technicians always check the fan motor before reassembly. Bearing lubrication instantly helps a dry, noisy motor run quietly again. Heavy dirt buildup easily unbalances the blower, causing annoying rattles. We perform fan blade balancing to stop that wobbling completely. Once the unit is reassembled, a full test run guarantees icy cold airflow. Our main goal is complete biofilm removal. That slimy layer of bacteria is exactly what causes foul smells, sudden leaks, and frustratingly weak airflow. Getting the blower completely out of the unit means we can finally reach every single blade. Every complete overhaul includes a complimentary refrigerant top-up. We charge a flat rate of RM180 to RM220 per unit for this comprehensive service. ### Common Problems an Overhaul Solves Are you wondering if your air conditioner actually needs this much work? We see a few specific signs that tell us a standard service just won’t cut it. According to energy experts, ignoring these warning signs can actually increase your energy consumption by up to 30 percent. Our overhaul directly addresses these frustrating issues: - **The smell comes back after a chemical wash.** Washing a unit in place simply cannot reach mould spores buried deep inside the blower wheel housing. We soak the removed blower to eliminate that sour, musty odour for good. - **A blower so clogged you can see the buildup.** Grab a torch and shine it straight through the louvres. If those blades look coated in grey or black fuzz, your airflow is severely restricted. - **Units that went years without service.** Rentals, older homes, and forgotten systems definitely need this deep clean to function properly. We find that units ignored for over two years always require a full dismantle. - **A noisy, wobbling fan.** Heavy dirt buildup throws the blower completely off balance. We clean the blades and balance the fan to solve that annoying rattling noise. ## When Is an Overhaul Worth It? Not every dirty aircon requires a complete dismantling process. We never sell you an expensive service if a basic clean will do the job. A standard wash easily handles most residential units that get serviced at least once a year. An overhaul is absolutely worth it when a basic wash fails to restore the cooling power. You should also consider this service if you are taking over a neglected unit in a new home or rental.

Removing and soaking the blower does. ### Blower caked with dust Units that went years without service often have blades so clogged that airflow drops sharply. ### Wobbling or noisy fan Heavy buildup throws the blower out of balance. Cleaning and fan blade balancing quietens it down. ### Recurring leaks from sludge Thick sludge in the drain pan keeps blocking the outlet. A full overhaul removes the pan and clears it completely.

A complete overhaul costs RM180 to RM220 per unit and includes full dismantling, component washing, reassembly and a complimentary gas top-up. Several units at the same address get a multi-unit discount. Should I choose an overhaul or a chemical wash? Choose a chemical wash for routine deep cleaning. Choose an overhaul if the unit hasn't been serviced for years, the blower is clogged, or the smell comes back after a wash. How long does an overhaul take? Longer than a chemical wash. Plan for a few hours per unit, because every part is removed, soaked, cleaned and put back. Is the gas top-up really included? Yes. Every Complete Overhaul includes a complimentary refrigerant gas top-up. We still check the pressure first, and if there's a leak, we'll tell you. Is my unit taken away? No. Everything is done on-site. We usually set up the soaking tubs on a porch, balcony or bathroom floor. How often should I overhaul my aircon? Not routinely. An overhaul is for units a chemical wash can't restore. With regular servicing and the occasional chemical wash, most units never need one. Is an overhaul cheaper than buying a new unit? Much cheaper. RM180 to RM220 compared with RM1,500 or more for a new unit plus installation. If the unit has a major fault as well, though, we'll compare the options honestly. Can you overhaul several units in one Subang Jaya house? Yes. Subang Jaya and USJ terraces often have 3 to 5 units, and we schedule them in one visit with the multi-unit discount applied. ### Still have a question?
