Resolution 1: Voltage Stabilisation

The Impact of Electrical Surges on Aircon Operation


Ever seen your aircon blink unexpectedly? It’s like a little protest due to electrical ups and downs. Your aircon follows the beat of unpredictable voltage changes, messing up its smooth operation.


Now, when there’s a sudden voltage surge, your aircon blinks in protest. This not only messes with its performance but could also cause long-term damage and higher energy costs. To fix this, think about using a voltage stabiliser. It’s like a guard, making sure your electrical environment stays steady. With this control, your cooling buddy can work smoothly, avoiding any flashy light shows and potential damage from voltage changes.


Resolution 2: Filter Maintenance Service

The Critical Role of Filters in Aircon Functionality

Temperature Control with the Thermostat


Think of your aircon thermostat as the one in charge of keeping your home at the right temperature. But what if this controller loses its accuracy? A misbehaving thermostat can lead to unpredictable temperature changes, making your aircon’s light start blinking unexpectedly.


For example, setting your thermostat for a cool evening, but the room starts feeling too warm, and the aircon light begins to blink. To fix this, regularly adjusting your thermostat is important. It’s like tuning a musical instrument, making sure your aircon works smoothly with the right temperature, without any bothersome light shows.

Implementing Regular Blinking Light Inspections


Regularly checking the blinking lights of your air conditioner is like inspecting your car for strange sounds. Imagine you set your aircon to cool your room, but suddenly, the blinking lights start acting up, signalling a potential issue. It’s similar to your car making an unexpected noise.


By staying alert and consistently watching for these blinking patterns, you can catch issues early on. For instance, if you notice a specific blinking sequence that’s not usual, it could indicate a problem with the system.


Hence, you can take immediate action by calling in a professional aircon servicing technician to have troubleshooting & repair for your aircon. These proactive maintenance steps help prevent potential aircon problems, allowing you to address them in time before they worsen.
