With the ever-shifting Singaporean weather, if you find that your air conditioner suddenly stops working in the day or night, you’ll want to have it fixed—stat. Usually, aircon problems need the help of an AC technician, especially if the problem is complex. However, if you know how to identify and troubleshoot some of the most common problems that occur with air conditioners, you might be able to prevent larger issues from happening and save money on maintenance fees. Here are some tips to help you figure out what’s up in the event your aircon goes awry:
1. Air conditioner isn’t turning on
If turning on your aircon requires several presses of the button—or if it’s not turning on altogether—do the obvious and check if the unit is properly plugged in. If it is, it might be a blown fuse. If you see that the fuse is okay, then it might be something to do with the wiring. At this point, you should be hiring a technician to check the wiring to see if the unit is still receiving power. If it’s not the wiring, then it might be the compressor or motor at fault.
2. Air conditioner isn’t cooling the room enough
Another common aircon problem with uncomfortable results, this aircon issue can be caused by a number of factors—but it’s usually due to dirt and grime build-up. Dirty evaporator coils and filters can hinder the cooling power of your unit. If it’s not those, then it might be a faulty thermostat. If the problem doesn’t go away even after you set a lower temperature, then it’s time to hire a technician.
3. The air conditioner is leaking water
Usually caused by a bad installation process, water leakage from the aircon can do a lot of damage to your walls, and should be nipped in the bud as soon as possible. This problem might be due to the water drainage channel being blocked off by dirt and debris. In any case, you’ll need a professional to chemically clean the unit to get rid of the problem.
4. The air conditioner is unnaturally noisy
We’re all used to the rumble of an air conditioner, especially if it’s a particularly old model. However, if the unit is excessively noisy, then that’s a sure sign that the unit needs service or repair. The noise might come from dirty evaporator coils, faulty motors, or loose internal components, and will need a servicing from an AC technician for it to get fixed.
5. The air conditioner is turning on and off repeatedly
When dust particles accumulate on the filters or the evaporator coils, a lot of normal air conditioning processes get affected. One of those is your air conditioner’s power system. If your aircon is turning on and off automatically at random intervals, then you need to give the air conditioner a good cleaning. If the problem persists even after DIY-cleaning the evaporator coils and the filters, then you’ll need to have a professional conduct a chemical clean on your unit.
6. The outside fan of the air conditioner isn’t working
Your aircon’s outdoor fan functions to release heat from the inside of the room to the outside. If the outside fan stops working, it’ll cause heat transfer issues that’ll eventually cause the entire system to overheat, and might even cause internal damage to the compressor. This one is tricky as it’s hard to notice if you’re constantly indoors, so make sure to check the outside unit of your air conditioner regularly. If you notice any problems, you’ll want to call an AC technician immediately.
Most of these problems are caused by three things: faulty installation, improper unit handling, or negligence for aircon maintenance. You can avoid most of these problems by ensuring proper installation and maintenance with a reputable aircon services company.
