In this article we look atthe most common air conditioner problems, how to check for them, and what action needs to be taken to fix them. We’ll take a look at some issues require professional assistance as well as those problems that can be solved by yourself.

Issues That Necessitate the Services Of A Professional

Checking and cleaning the outdoor unit (ODU)

For some, checking the outdoor unit can simply require them to go to their garden or driveway and double-check that there is no plant matter or debris covering or blocking the unit. However, if you are living in an apartment or high-rise building, it is possible that your ODU is on a balcony, on the rooftop, or even on wall brackets. In these cases, it is essential that you call a professional to come and check it out.

One of the signs that your ODU needs cleaning is inadequate cooling inside the home. Just like indoor unit filters, ODUs can suffer from a buildup of dust, dirt, and debris, and this can impact the temperature that you want to achieve indoors. If your ODU is on ground level and accessible, this is something that you can investigate yourself and see just how dirty the system is. If the cause of the problem is indeed buildup around the unit’s casing, then you can clean it yourself. But if your ODU is attached to the side of the building, then it is time to call in the professionals and let them handle it.

Waterdripping from Indoor Unit

If your AC unit is leaking, it’s most likely just water. Water dripping is generally a symptom of the drain pipeline becoming blocked with the dust and dirt that flows out of the IDU with the condensation during operation. This can lead to mould and fungus growing, and subsequently catching other particles passing through the pipeline. As this happens, the condensation can’t drain and leads to droplets building up and falling from the IDU.

This is generally easy to identify on wall-mounted units as visible water droplets will gather on the casing. There are other ways to tell if the unit is leaking too. This not only causes water to leak from the unit, but it can also cause gases and bad odours to be released into your home, reducing comfort.

A dirty filter could also be the culprit. Why? Because if the air can’t pass through the unit effectively, this means that the evaporator coil isn’t receiving warm air and it freezes. When any moisture in the air hits the evaporator coil, this also freezes, creating ice crystals within the unit, which later melts and can eventually leak out of the IDU.

The latter problem can be avoided by adhering to decent filter maintenance but when your IDU is producing a leak, our recommendation is to contact our technical service team before attempting to fix it yourself.
