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, 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. Our detailed guide on when an aircon overhaul is worth it lists all the red flags to watch for.
Reading the chemical wash vs chemical overhaul comparison gives you a clear side-by-side view.

How Much Does an Aircon Overhaul KL Cost?
A complete deep clean runs between RM180 to RM220 per unit. We base the exact price on the specific size and condition of your air conditioner.
Booking multiple units at one address instantly qualifies you for a multi-unit discount. The final price includes the free gas top-up and a complimentary 7-day follow-up check.
Our technicians sometimes spot separate hardware faults, like a blown capacitor common in York units, during the initial test run. If we find a failing sensor or a gas leak, you get a clear repair quote before any extra work begins.
Knowing exactly what you are paying for gives you peace of mind. We encourage you to read exactly what happens during an aircon overhaul so there are no surprises on the day.
