Common Aircond Problems We Diagnose and Fix
Is your aircond acting up? CoolBreeze Aircond Services handles all types of aircond faults, from simple drain blockages to complex circuit board failures. Here are the most common problems we see from homes and businesses across Kepong.
Water Leaking from Indoor Unit
This is the single most frequent aircond problem in Kepong, and the humid tropical climate makes it worse. Water leaks are usually caused by blocked drain lines, dirty evaporator coils pushing water off the drain pan, or cracked drain pans on older units. In many terrace houses in Taman Kepong and Kepong Baru, drainage routing can be tricky due to the building layout, and improper installation sometimes contributes to recurring leaks.
Our technicians clear the blockage, flush the drain line, and check the insulation to prevent condensation dripping. If the drain pan is damaged, we replace it with the correct part for your unit model.
Not Cooling Properly
Your aircond runs but the room stays warm. This could be caused by low refrigerant gas, heavily soiled evaporator coils reducing heat transfer, a failing compressor, or even incorrect thermostat readings. We systematically test each possibility to identify the actual root cause rather than guessing.
If the problem is dirty coils, we will recommend a chemical wash. If it is low gas, we check for leaks first and then top up. For compressor issues, we give you a clear picture of repair cost versus replacement value so you can make an informed decision.
Strange Noises and Vibrations
Rattling, buzzing, grinding, or clicking sounds coming from your aircond are never normal. These noises can indicate loose components, a failing fan motor, worn bearings, or debris caught in the blower. Ignoring these sounds usually leads to more expensive repairs down the line.
CoolBreeze technicians pinpoint the source of the noise and address it properly, whether that means tightening loose parts, replacing a worn fan motor, or removing foreign objects from the system.
Unit Not Turning On
When your aircond does not respond to the remote control or wall switch at all, the problem is usually electrical. Common causes include blown fuses, faulty capacitors, damaged PCB (circuit board), or wiring issues. Our technicians use multimeters and diagnostic tools to trace the fault and identify exactly what needs replacing.
Capacitor failures are particularly common in Kepong due to the frequent power fluctuations in some older neighbourhoods. We carry common capacitor sizes in our service vehicle so most replacements can be done on the spot during the same visit.
Blowing Warm Air
An aircond that blows air but provides no cooling is frustrating, especially during Kepong’s hottest months. This typically points to low refrigerant, compressor failure, or a problem with the reversing valve. We check the gas pressure first and work through the diagnostic process to find the exact cause.
How Our Repair Process Works
CoolBreeze keeps the repair process simple and transparent:
- Describe the problem: Send us a WhatsApp message at 03-6277 8899 with a description of what is happening. Photos or videos of the issue help us prepare.
- We schedule and diagnose: Our technician visits, inspects the unit thoroughly, and identifies the problem. We explain what we found in plain language.
- You get a written quote: We provide a clear repair quotation with no hidden costs. The RM50 diagnostic fee is waived if you proceed with the repair.
- You decide, no pressure: Take your time. There is no obligation to proceed if the quote does not work for you.
- We fix it: Most common repairs are completed during the same visit, backed by our 90-day workmanship guarantee. If specific parts need to be ordered, we schedule a return visit at your convenience.
Genuine Parts and Lasting Repairs
CoolBreeze uses only genuine OEM parts for all repairs. We do not use third-party substitutes or refurbished components. This matters because generic parts often fail sooner, leading to repeat breakdowns and additional repair costs.
Our technicians, led by Marcus Tan (CIDB Registered, Daikin Certified) and Faizal (Mitsubishi Certified, Licensed Refrigerant Handler), have the training and experience to diagnose problems accurately and fix them right the first time. With over 5,200 completed projects, we have seen virtually every aircond issue that exists in Malaysian homes and offices.
When Repair is Not Worth It
Sometimes the most honest advice is to stop spending money on an old unit. If your aircond is over 10 years old and needs a major repair like a compressor or PCB replacement, the repair cost often approaches half the price of a brand new unit with a full manufacturer warranty.
In these situations, CoolBreeze will always be upfront with you. We will explain the repair cost, compare it with replacement options, and help you make the decision that makes the most financial sense. We would rather earn your trust and future business than push an expensive repair on a unit that is past its useful life.
