5 Signs Your Aircon Needs Repair/Replacement
Noticing any signs that the aircon is due for repairs keeps your air conditioner functioning properly with a quick and efficient aircon repair whenever you need it. Not all signs of due repairs are obvious at first glance. However, you will be better equipped to identify 5 signs that your aircon needs repair or replacement.
Obvious dirt outside the unit
Check around your air conditioning unit to see if there are loads of dirt close to the outdoor unit. If there is a lot of dust or debris around your air conditioner, it is an indication that you may need to repair your aircon in the future.
Aircon not cooling
The most obvious sign that you are in need of aircon repair is when you are unable to feel the coolness of the aircon when it is working. Most times, the cause may be something that professional aircon services can fix without you having to go through the hassle of doing an aircon replacement.
Increasing electricity bill
Another sign that will tell you your air conditioner is faulty will be an increase in your monthly electricity bills. Faulty air conditioners consume more electricity than normal and this may cost you lots of money. In order to avoid experiencing such situations, it is important to schedule regular aircon servicing.
Unnatural shutdowns
When your aircon shutdowns unexpectedly and also quite frequently, you can be sure that this is a clear sign that it needs a repair. It may be due to a circuit problem or its wirings.
Bad odors
When you notice your aircon producing bad smells, you should be calling an aircon repair company immediately. The reasons why the aircon smells bad may be a result of gas leakage, an inability of the filters to keep out allergens, or a sign that mold and other microbes are growing in the unit.
Knowing the signs your aircon needs either a repair or replacement is important as it can help you decide if an aircon repair or a replacement is necessary. Additionally, it is essential to know the symptoms that indicate an aircon repair is necessary.
Aircon Repair Symptoms
There are a variety of reasons why your aircon unit is experiencing problems – while some may just need a gas top-up, other units may require an aircon chemical overhaul. Nevertheless, every homeowner should be familiar with the different aircon repair symptoms. Do not hesitate to call a reliable air conditioner repair company as soon as you notice these aircon repair symptoms:
Aircon Not Blowing Cold Air
Your aircon unit can be experiencing a weak airflow, which leads to your aircon not being cold or it might be blowing out hot air. Oftentimes, symptoms like these indicate a faulty system compressor and capacitor, or even a blown fuse. Whatever it is, get it repaired as soon as possible to prevent worse aircon problems like a refrigerant leak.
Gas Pipe Leakage
In some cases, the unpleasant odor of poisonous Freon gas is quickly noticeable when the aircon leak is happening from your indoor unit. However, you might have to check your outdoor compressor unit for such smells.
Remember to also inspect the pipes and look out for some stains as this can also be a sign of an aircon gas pipe leak. Lastly, you can also check for whistling sounds coming from your thermostatic expansion valve, which suggests low refrigerant levels.
Water Leakage
An aircon water leakage can also display itself on either the indoor aircon unit or the outdoor compressor. You may be noticing water dripping from your fan coils or ice building up on your copper refrigerant lines.
Aircon Unit Switching Off Automatically
An aircon that switches off by itself can be caused by various problems stemming from not carrying out regular air conditioner servicing. A dirty aircon compressor or condenser can lead to overheating, which then prompts the system to shut itself down. Are you still experiencing this problem despite getting your aircon regularly cleaned? Well, the issue might be from your thermostat. A broken thermostat will not be able to correctly gauge the temperature of your aircon, which can cause it to shut down automatically.
Blinking Light
There are times when you may notice your aircon light blinking and wonder how to fix it. Take this blinking light as a warning sign that your aircon is experiencing problems that require immediate attention. Just take note that it can be due to the following problems:
- A faulty compressor
- Low refrigerant levels
- Electrical issues
- Dirty filters
Compressor Not Running
Check that the start relay, the capacitor, valves, and terminal connections are functioning per normal. Otherwise, you will need to engage in the services of professional aircon services to solve the issue.
Generating Noise
If your aircon is noisy, this could very well be a result of a belt slipping out of place or other aircon parts that need to be lubricated. Get an experienced aircon technician to look into the issue and troubleshoot common aircon issues.
Releasing Foul Odour
If you are noticing a pungent smell from your aircon and think that it is nothing to worry about – remember that air conditioners aren’t supposed to release a foul odour. The odour can either come from burnt wiring that should be replaced immediately or moldy ductwork.
After knowing the aircon symptoms that require aircon repair services, knowing how to troubleshoot these common aircon issues can help your aircon’s performance.
Troubleshooting Common Aircon Issues
Occasionally, there are issues with the aircon, especially if the aircon has been around for a number of years. Troubleshoot common aircon issues early by opting for an aircon servicing contract in Singapore will ensure that you stay comfortable during the warmer months. With this being said, here are a few common problems that may occur with your aircon.
Aircon not turning on
As you turn on the unit, is it silent? Are you unable to feel or hear anything? In such situations, the blown fuse and circuit breaker should be replaced/reset. Sometimes, air conditioners will not turn on if there are thermostat issues or loose wires. In such cases, you must hire a professional aircon repair service.
Suspected faulty thermostat
These glitches can be prevented with periodic maintenance. If the thermostat gives a low reading and the aircon does not start, you must call for a professional aircon service. They will advise you whether to replace or recalibrate the device.
Room not cooling down
If your home/room is not cooling enough, you must have the cooling component inspected, particularly the refrigerant level – as this might be one of the reasons why your aircon is not blowing cool air. In fact, low refrigerant levels can result in the sticky air. The right amount of refrigerant is required to control humidity and heat in the air.
Aircon Heating up
Heating issues are caused by faulty condensers. The condenser plays an integral role in the air conditioner. It removes heat and releases it outdoors. With excess soot, pollutants, and dirt, the condenser has to work harder to remove heat. This is when the aircon starts to wear and tear.
Mentioned above are the ways you can troubleshoot common aircon issues that you might face. However, this might not be enough as it is advised that you also know some useful aircon repair tips for your home.
