Why is my aircon not working properly?

With winter now in full swing, you might find that your air conditioner is not producing the necessary heat to create a comfortable environment. There are a few factors that could impact the efficiency and effectiveness of your aircon unit.

Aircon size

The first thing you need to consider is the air conditioner size. If your aircon is not operating at its full capacity, it might be that the space you want to cool is heat is too large for the size unit you currently have. An aircon that is too small will have to work a lot harder which results in excessive wear and tear. On the other hand, if your aircon unit is too large for the room you want to heat, it will over heat your room and have shorter heating cycles which uses more electricity. Our experts are able to advise you on the right size for the room you want to heat or cool.

Using your air conditioner

Air conditioners should essentially only be used when you are actually using the room or space. If you are utilising the space, then it is important to close all doors and windows because it will drastically reduce the time you have to run the unit. For heating purposes, try not to turn up the temperature too much. When the difference between is temperature on the inside and outside are relatively small, it will lower the amount of electricity needed.
If you have an air conditioner that can be programmed, you can pre-heat your room on the eco mode to reduce your energy consumption. Certain aircons can even detect if people are actually in the room and then adjust the output as needed.

The state of your aircon and the area around it

Decent circulation around the inside and the outside of your aircon unit is important to maintain the heating efficiency of your aircon. Make sure that furniture, plants, curtains and other appliances are kept well away from your aircon and make sure that these items are a dust-free as possible. A build-up of debris will cause that your unit will have to work so much harder to heat or cool your home – this increases energy use. It’s also advisable to wipe down your aircon unit’s surfaces on the inside and outside.

Dirty or faulty filters

This could be one of the biggest reasons that your air conditioner is not functioning properly. When your aircon gets a service, it’s vital that air filters are cleaned or replaced. Aircons filter out dust and other particles from the air to supply clean, healthy air. Dirty filters and vents decrease your aircon’s productivity and could also lead to health problems like allergies and asthma. To reduce these issues, your system should be cleaned every few months.

Regular servicing

Servicing your aircon on a regular basis will help maintain it’s heating and cooling efficiency and prolong the life of your aircon.
