Having your air conditioning system serviced should not be left until something goes wrong.
Generally, if your split system air conditioner is aging and an older model or has high demand use, such as those in commercial settings, regular servicing is imperative.
So why not take this proactive approach now and do yourself and your split system aircon a favour?
Key signs it's time for action include:
If you notice that your air conditioner is not cooling your space as effectively as it used to, it may be a sign that the coils or filters are dirty and restricting airflow.
A dirty air conditioner has to work harder to cool your space, leading to increased energy consumption. If you see a sudden spike in your energy bills without a corresponding change in usage, it might be time to clean your AC unit.
Insufficient airflow from the vents is a common sign of a dirty or clogged air filter. Reduced airflow can also lead to uneven cooling in different parts of your home.
Foul or musty odours can indicate the presence of mould or bacteria in the system. Cleaning the unit and replacing filters can help eliminate these odours.
Unusual sounds like rattling, hissing, or banging can indicate various issues, including loose components or debris in the system. Cleaning the unit and checking for any loose parts can resolve these problems.
If you or your family members experience an increase in allergy symptoms or respiratory issues when the AC is running, it could be a sign of mould or dust circulating in the air. Cleaning the unit and replacing filters can improve indoor air quality.
Moisture or water leaks around the indoor unit can be a sign of a clogged condensate drain. This can happen when dust and debris accumulate, hindering the drainage process.
If your AC is turning on and off more frequently than normal, it could indicate an issue with the thermostat or internal components.
Routine servicing for your split and multi split system air conditioner is essential to help remove bacteria, dirt and dust, ensure all components are in good condition and improve air quality.
Air conditioning systems are known to be breeding grounds for a variety of nasties and homes to cute but pesky geckos. When left unchecked over time, that's when problems start occurring.
