Call 012-716 4653 [tel:+60127164653 →](tel:+60127164653) 5.0 ★ Google 69 reviews Same-day PJ response Written quote Before any work Pay on completion Cash · DuitNow · QR Have you noticed a sudden spike in your monthly TNB electricity bill? A dirty air conditioner is often the hidden culprit, forcing the compressor to overwork and driving consumption straight into the expensive 51.60 sen per kilowatt-hour tier under the 2026 rates. Booking an Aircond Chemical Wash & Chemical Overhaul is the most effective way to restore efficiency. AMg Aircond Servicing technicians in Petaling Jaya, rated 5.0 stars across 69 Google reviews, find that this targeted deep clean on wall-mounted split units and ceiling cassettes resolves the problem of high electricity costs across Selangor. A standard service just rinses surface dust, but a chemical treatment uses professional-grade alkaline foam to dissolve stubborn mineral scale and biological slime. We’re going to walk you through exactly how this works, step by step. Grab a cup of coffee, and let us show you how to get your cooling back on track. ## Which Cleaning Level Does Your Unit Need? In Petaling Jaya, the constant 80% humidity means evaporator coils in residential and commercial units accumulate thick gunk far faster than standard dry-climate manuals assume. Aspergillus mold and a jelly-like biofilm love to breed in your drainage pipes. Our specialists evaluate every unit carefully before recommending a specific cleaning level, whether you own a terrace house, condo, or shoplot office. This honest approach prevents you from paying for a massive overhaul when a simple tune-up would do the trick. | Service Tier | Duration | When You Need It | | --- | --- | --- | | Normal Service | 45-60 minutes | Keeps a healthy unit running smoothly. Includes a filter wash, surface coil rinse, drain hose check, and gas pressure verification. | | Chemical Wash | 90-120 minutes | Solves mid-stage problems like mild musty smells or slightly weak airflow. Ideal if it has been over 12 months since the last deep clean. | | Full Chemical Overhaul | 2-3 hours | Rescues units with visible mold on the louvers or persistent water leaks despite a clear drain hose. The entire indoor unit is completely dismantled. | We always inspect the situation first and give you clear advice on the right tier. Sometimes, a full overhaul can save an older aircond that a customer was ready to throw away. A thorough chemical wash restores airflow and cooling efficiency, helping units last past the typical 10 to 15 years expected in Malaysia. ![AMg Aircond chemical overhaul - indoor unit dismantled with evaporator coil and drain pan at a Petaling Jaya home](/images/misc/aircond-indoor-unit-fully-dismantled-during-chemic.webp) ## Our Coil & Drain Pan Deep Clean Process 1. **Preparation and Protection:** The actual cleaning process requires careful preparation before any chemical even touches your walls. Your home and furniture deserve total respect during the job. Our crew starts by laying down drop cloths over your floors and fitting a waterproof canvas wash bag tightly around the indoor unit. Safety is paramount, so shutting off the power at the main AC isolator happens next. 2. **Dismantling and Foaming:** We then systematically remove the front panel, filter, blower wheel, and drain pan to fully expose the evaporator coil. A professional-grade alkaline foaming cleaner is applied directly to the dirty components. This specialized foam clings tightly to the delicate aluminum fins instead of simply dripping off, giving it a crucial 10 to 15 minutes of contact time to break down heavy buildup. 3. **High-Pressure Rinsing:** Our team then uses a high-pressure neutral rinse to blast away the dissolved gunk and ensure zero chemical residue is left behind. The drain pan and hose receive this exact same intense treatment. Thick biofilm colonies in the drain hose are actually one of the most common reasons for annoying, intermittent water drips inside your bedroom. 4. **Testing and Verification:** We carefully reassemble every single piece once everything is sparkling clean. A vacuum test verifies the integrity of any touched refrigerant lines, followed by a strict gas pressure check using a manifold gauge. If the R32 or R410A refrigerant level is low, we recommend a gas top-up on the spot so cooling output is fully restored. The final step is running a 10-minute temperature test at the supply louver before we ever ask for your signature. ## What PJ Homeowners Notice After Service What you’ll notice immediately after a deep clean usually comes down to three clear improvements. Customers across Petaling Jaya report a clear difference in everyday comfort. Here’s what changes: - **Stronger Airflow:** The breeze is visibly more powerful. You can hold your hand a full metre below the supply louver and clearly feel the cold air rushing past. - **Faster Cooling:** The time it takes to cool down a hot room drops by several minutes, taking the heavy workload off your compressor. - **Zero Odours:** Removing deep biofilm stops the spread of volatile organic compounds (VOCs). That embarrassing wet sock smell that used to drift out for the first 30 seconds simply doesn’t happen anymore. The AMg Aircond team runs every job to this exact standard. Dozens of Google reviewers across Bayu Puteri, SS2, Damansara Utama, Kelana Jaya, and Puchong consistently highlight these same positive results. They appreciate that the room is left spotless, the technical work is explained in plain English, and the final invoice perfectly matches the written quote with zero hidden fees.

Chemical wash uses phosphoric or alkaline coil cleaner to dissolve mould, scale, and biological slime that water alone can't reach. A full overhaul goes further - full disassembly of the indoor unit, soak each component, then rebuild. How long does a chemical wash take? + Standard wall-unit chemical wash takes 90-120 minutes per unit. Full chemical overhaul takes 2-3 hours. Cassette units take longer (90 minutes plus scaffolding setup) because of the ceiling-mounted access. Will the chemical damage my unit or leave a smell? + No. Coil cleaners are designed for HVAC use. We rinse thoroughly with a neutral rinse so no residue remains, and the smell clears within 30 minutes of finishing. How often should I do a chemical wash? + Every 12-18 months for residential daily-use units. Every 6-9 months for commercial cassettes, smoker households, or homes near construction sites. If you're noticing mouldy smell or weak airflow already, it's overdue. Does a chemical wash include a gas top-up? + A gas top-up is not included in the standard chemical wash price. During every job we check the R32 or R410A refrigerant pressure with a manifold gauge. If the level is low, we quote the top-up separately so you only pay for what you actually need. ## Related guides Deep-dive reads on Chemical Wash — written by the AMg team.
