With summer temperatures heating up, residents across Australia will be using their air conditioners frequently. But one thing that’s common with AC units during summer is performance issues and breakdowns. You may need to have your system repaired, particularly if it cannot cool a room efficiently. If you find yourself in such situation, don’t panic. Just call your local plumber if you can’t fix it. Here are some of the common repairs for residential air conditioning systems:

Common Home Air Conditioning Issues

Refrigerant Leak

Leaking refrigerant is among the most common problems with home AC units. Refrigerant is the fluid that allows the system to run efficiently by releasing heat from the air to cool it. If the level falls below the required amount, then it will affect the performance of the AC unit. In the case of a refrigerant leak, you need a professional plumber to fix the problem. The contractor should also fix the source of the leak. It’s important to have the unit recharged to the proper amount of refrigerant to avoid the problem reoccurring.

Drainage Issues

Aircon Drainage SystemThis is another problem that’s common with home AC units. The cooling process of an air conditioner produces condensation that normally flows away from the unit. But a problem can arise if there is a clog in the condensate drain lines. Also, if the outdoor humidity levels are high, moisture backing up in your unit is like to cause drainage issues. Similarly, if there’s an excess of condensation, indoor humidity levels will be increased, and this will hinder the unit’s performance. AC technician should inspect the drip pan and drainage lines and clear any clogs. The unit should also be treated for algae growth to prevent future clogs.

Broken Compressor Fans

This is a common problem with outdoor units. Note that outdoor units contain condenser coils, compressor and the fan. They are responsible for releasing heat from your house to the air to keep the room cool. In this process, the outdoor fan plays a huge role in transferring this heat, and if it’s not working properly, then your AC unit will have a problem. Most of the time it will cause the compressor to overheat, and this will trigger the safety control to turn off the air conditioner. Other than that, it can damage other parts of the unit. You need a technician to fix the fan. Sometimes a replacement is necessary.

Frozen Condenser Coils

This is a serious problem that can affect the performance of your home air conditioner. The main reason why the condenser coils may freeze up is poor air flow. Many other factors may also cause frozen condenser coils such as a faulty fan, dirty filters and blocked return air duct. You should also ask the technician to check the level of refrigerant among other issues behind this problem.
