The sticky heat instantly ruins your comfort. Our service team is built around showing up fast and finding the real problem. A quick fix requires the right tools and a proper diagnosis. We will walk you through exactly what this repair process covers and how much it costs. Grab a cold drink. Everything you need to know is laid out right here. ## What Does Our Aircon Repair Service Cover? We require every technician on our professional service team to have at least three years of hands-on experience. This ensures an expert comes to your home within 24 hours to diagnose the fault properly. Our crew will always tell you exactly what the repair costs before any work starts. Guessing is never part of a reliable diagnosis. Highly accurate tools are essential to pinpoint the exact issue quickly: - A **digital manifold gauge** reads the refrigerant pressure at the outdoor unit service valve. - A **clamp meter amp check** tells the technician whether the **rotary compressor** and fan motors are drawing the correct current. - Our technicians use a **digital multimeter** to test the **run capacitor**, the **magnetic contactor**, and the wiring. Testing the indoor side requires checking the **thermistor sensor**, the **printed circuit board (PCB)**, and the drain path. We usually find the root cause of the fault within the first 30 minutes. Clear, plain English is how the problem is explained to you. Our quote includes a transparent price for labour and any specific parts like a new capacitor. Work only begins once you give the firm green light. ### Common Problems We Fix - **Aircon blowing warm air.** We receive calls about this frustrating issue more than anything else. A dirty coil, a failed capacitor, or low refrigerant from a leak can stop the compressor from starting. Poor airflow is another factor that often causes a **frozen suction line**. Our guide on why your aircon is not cold [/guide/why-is-my-aircon-not-cold/ →](/guide/why-is-my-aircon-not-cold/) walks through each cause and the quick checks you can do first. - **Water leaking inside.** This messy problem is usually caused by a clogged drain or a buildup of aircon jelly. We see this bio-slime form constantly because of Malaysia’s 80 percent humidity mixing with dust in the drain pan. Water dripping onto walls and wardrobes causes expensive damage very fast. Treat this situation as urgent and see why your aircon leaks water inside [/guide/aircon-leaking-water-inside/ →](/guide/aircon-leaking-water-inside/) for immediate steps. - **Rattling, buzzing or clicking.** Loose panels, worn fan bearings, or a failing capacitor often create annoying noises. We also frequently find chattering contactors in popular brands like Daikin or Acson. Some mechanical sounds mean you should switch the power off straight away to prevent further damage. Our guide on aircon noises [/guide/aircon-making-strange-noise/ →](/guide/aircon-making-strange-noise/) explains which ones are dangerous. - **A blinking timer LED or error code.** Each brand uses its own specific codes for sensor, communication, and compressor faults. We regularly see modern inverter units flag an **inverter IPM module** problem. Checking the manual is a good first step to decode the alert. See aircon blinking light error codes [/guide/aircon-blinking-light-error-codes/ →](/guide/aircon-blinking-light-error-codes/) for a comprehensive list. - **Outdoor unit not running.** A silent outdoor unit combined with a blowing indoor fan usually points to a broken capacitor or contactor. We find that the intense Klang Valley heat puts severe strain on these exterior parts. Fixing this promptly restores cooling power to your home. Read more in outdoor unit not running [/guide/aircon-outdoor-unit-not-running/ →](/guide/aircon-outdoor-unit-not-running/) . - **Leaks at the flare joint.** A poorly made or corroded **flare nut joint** lets refrigerant gas escape slowly. We locate these hidden leaks using a specialized electronic leak test or soap solution. A proper repair must be completed on the joint before any new gas is added. Our technicians will then recharge the system so it runs perfectly again. ## How Much Does Aircon Repair Cost in KL? We keep our repair labour costs strictly between **RM80 and RM200**, depending on the complexity of the fault. This fee covers the professional diagnosis and the manual work required to fix the machine. Specific parts like a new capacitor, fan motor, sensor, or circuit board are charged as extra. Our team will always provide a firm quote for these components before fitting them. Ignoring small issues can cause your TNB electricity bill to spike rapidly. Getting early repairs is a smart financial choice. | Type of fault | Where labour usually falls | Notes | | --- | --- | --- | | Drain unclog, loose wiring, sensor reset | Lower end of RM80 to 200 | Often fixed on the first visit | | Capacitor or fan motor replacement | Middle of the range | Part priced separately | | Leak repair, PCB or major component | Upper end, up to RM200 | Gas recharge or parts quoted separately | We will tell you honestly if the fault is simply a dirty unit rather than a broken mechanical part. A thorough chemical wash [/aircon-chemical-wash/ →](/aircon-chemical-wash/) might be the only service you actually need. Low gas levels are always the result of a leak somewhere in the copper piping. Our technicians know that a gas top-up [/aircon-gas-top-up/ →](/aircon-gas-top-up/) only makes sense after that leak is permanently fixed. This honest approach prevents you from paying for gas that will just escape again. ## When Is a Repair Not Worth It? A failed compressor or a repeatedly failing circuit board on an older unit can cost a huge percentage of a brand new machine. We always compare the quoted repair price directly against the cost of a new inverter unit for you. According to the Suruhanjaya Tenaga (Energy Commission), upgrading to a 5-star rated inverter model can reduce your electricity consumption by up to 60 percent. These monthly savings on your TNB bill often make a replacement the much smarter financial decision. Our detailed guide on whether to repair or replace an aircon [/guide/aircon-repair-or-replace/ →](/guide/aircon-repair-or-replace/) explains exactly how this calculation works. You can take your time and decide without any pressure. We offer a dedicated installation team [/aircon-installation/ →](/aircon-installation/) that can supply and fit a reliable replacement from just RM280 if that is the better call. Helping you stay cool and comfortable with professional aircon repair KL solutions is always the main goal. Upfront Pricing ## How Much Does Aircon Repair Cost?

Repair labour is RM80 to RM200 depending on how complex the fault is, plus parts if any are needed. Simple jobs like unclogging a drain sit at the lower end. Leak repairs or board replacements sit at the higher end. We confirm the total after diagnosis and before starting the repair, so the price never changes once we open the unit. How fast can a technician come? We guarantee a response within 24 hours. We operate 24/7, including weekends, public holidays and after-hours appointments, across the Klang Valley, Penang and Johor Bahru. Why is my aircon running but not cold? The most common causes are a clogged coil or filter, low refrigerant from a leak, a failed run capacitor, or a compressor that isn't starting. Wrong remote settings happen too. We check pressure and amp draw to find the real cause, then quote the fix. Is it just low gas? Sometimes, but not always. A sealed system doesn't use up gas, so low pressure means a leak somewhere. We confirm with a pressure check and recommend fixing the leak instead of repeated top-ups. Which aircon brands do you repair? We repair all major brands sold in Malaysia, including Daikin, Panasonic, Mitsubishi, Acson, LG, Samsung, Sharp, Midea and Hitachi, both inverter and non-inverter models. Will the price change after the technician opens the unit? No. Our prices are flat and published. If a repair or extra part is needed, we explain it and confirm the price with you before any work starts. My aircon is blinking. What does it mean? A blinking timer or operation light is an error code. It can point to a sensor, a communication fault between the indoor and outdoor units, or a compressor protection trip. Our guide to aircon blinking light error codes explains the common ones by brand. Can you repair older aircons in Petaling Jaya? Yes. Many older PJ terrace and landed homes still run ageing non-inverter units. We diagnose them on-site and tell you honestly whether a repair or replacement makes more sense. Do you repair inverter aircons? Yes. Inverter units have more electronics, such as the inverter IPM module and control board, so diagnosis takes a little more care. Servicing costs the same. Some inverter parts cost more to replace, and we'll quote them upfront. Is there a warranty on repairs? Every repair gets a 7-day follow-up check. If the same fault comes back, we come back. Parts carry the manufacturer's warranty where one applies. ### Still have a question? Send us your unit type, HP and area on WhatsApp. A technician will reply with a straight answer.
