Improper installation is the cause of many air conditioning faults that can occur over time. Consequently, it is important that you work alongside a trusted installer that offers a guarantee on all work they carry out. The newest blog post from Air Conditioning Direct discusses some of the most common air conditioner problems.

Refrigerant Leaks

When an air conditioner is low on refrigerant, it usually means that it was undercharged at installation or there is a leak. The performance and efficiency of your system will be at its best when the refrigerant charge exactly matches the manufacturer’s specifications.


Over time, the filters and coils in your air conditioning unit can harbour trapped dust and dirt, leading to an efficient performance. To ensure your air conditioning unit works at it best, regular maintenance should be carried out. If your air conditioner is left to build up dirt, the compressor fans may stop working prematurely.

Electric Control Failure

If an air conditioner is turned on and off frequently, the compressor and fan controls can wear out at a quicker rate. One of the most common reasons that an air conditioner is frequently turned off is due to it being too big for the space. All electrical connections should be checked during a regular service.


If you experience problems with the sensor for your air conditioning unit, the unit can begin behaving erratically, which can seem like a bigger problem than it may actually be. In some cases, it may be something as simple as the coil touching the sensor which just needs to be carefully moved.
