Common Signs of Aircon Failure

When you think of your air conditioning system, there’s always something to worry about. Of course, it’s normal for home and office appliances to malfunction every now and then. However, it’s important to deal with the issue as quickly and effectively as possible. The same goes for air conditioners. Whether at home or at the office, every air conditioner needs a certain level of maintenance in order to ensure proper operation.

Generally, when they happen, not everyone is able to troubleshoot their aircon’s issues on their own. For this reason, here are a few helpful tips that will definitely improve your knowledge of ACs and troubleshooting AC problems.

Condenser Malfunction

First of all, the outdoor condenser does a huge bulk of the work. In addition, being outdoor means even more problems. Therefore, it’s not a big surprise if the condenser malfunctions. What you should do is check if the air conditioning unit has power and is plugged in. The second thing you should check is the thermostat. If the problem is in the AC, try lowering the temperature around 5 degrees. If the problem comes from the heater, try doing the opposite.

If the condenser still doesn’t turn on, then the issue might be in a faulty motor or bad compressor. In such cases, you should contact a professional to fix it.

Warm Air

Secondly, after some time, your air conditioner might start blowing warm air. You might not pay attention at first, but if you’re trying to cool your room unsuccessfully, then you have to check for any malfunctions. The first thing to check is the thermostat. Try lowering it by around 5 degrees to see if the aircon turns on. If you need to relocate your thermostat or your unit constantly blows warm air, you have to contact a professional. Even though this might not be a serious issue, it may also be a serious sign of expensive repairs.

Low Power

If you’re experiencing low or weak airflow power, then you can try some DIY fixes. Some of them include replacing the air filter, opening the vents and registers or sealing duct leaks. However, weak airflow often indicates AC compressor failure. This will definitely need a professional to solve the issue. Also, it’s suggested that you schedule a regular air conditioner servicing at least once a year.

Loud or Strange Noises

Another common sign of AC failure is any buzzing, hissing, squealing, rattling or humming sounds that may occur. If this is the case, you should contact your local HVAC expert to investigate the problem. Most of the new AC models don’t have a belt system. However, older units have one which increases the chances of experiencing noise-related problems. On top of that, you will hear the noises both inside and outside of your house. What you should do is turn off the air conditioner until a professional deal with the issue. Such noises might opt for AC motor bearings replacement, a need for part lubrication or motor replacement.

High Electric Bill

Obviously, if your electricity bills are constantly going up, it’s time for you to check your aircon unit. Although there are lots of reasons why you may have higher bills than the usual, chances are high that your unit needs a repair or replacement. No matter what, it’s best that you contact a professional. By doing this, you’ll make sure there are no energy leaks, ductwork or insulation problems. You’ll also be able to check your AC efficiency and evaluate other problems that may occur.

Leaks

Often, moisture can cause problems. It can come either from refrigerant or condensate leaks. The former can be extremely poisonous, especially if you have pets or children at home. For this reason, if you suspect any Freon leaks, you should contact a professional immediately. As for the issue with the condensate drain pan or line, water can clog them which may result in water dripping down on the floor around your indoor air handler.

Dirty Coils

The coils in every AC’s cooling system are essential to the unit’s proper operation. They provide uninterrupted airflow but over time, they store up dust and dirt which require regular cleaning. However, you shouldn’t clean the dirty coils by yourself because it’s a job specifically designated for professionals. Therefore, it’s best advised that an aircon technician cleans the coils as part of the service.

Tips to Prevent AC Failure

First and foremost, you should schedule a professional air conditioning service at least once a year. The best time to do this is usually in the early spring. Then, you should clean your air filter regularly. Generally, it should be done every 30 days. Also, don’t forget to find and seal any air leaks. Consider adding additional insulation if necessary. This might require sealing duct leaks and air leaks around the home. Last but not least, ensuring that your aircon system works properly always has to be done with a professional HVAC technician.

At the end of the day, every air conditioning appliance has its approximate lifetime. Usually, aircon units last about ten years. If you change the filters regularly, check and evaluate any issues on time, you’ll do enough to extend your air conditioner’s life. For this reason, you should always rely on professionals. They can give your AC thorough maintenance and tell if there are any potential problems. In addition, a technician can predict the remaining life of your unit and some other things that can be troubleshot.
