Clogged filters, dirty evaporator coils, and freezing refrigerant lines are some of the common air conditioner problems and are easy to spot and fix. However, sometimes, when you have electrical issues related to the air conditioner, it is hard to tell what’s causing the problem. In fact, it could be challenging to determine whether the problem is with the air conditioner or the electrical system in your house.

In most cases, you need to call the aircon installation Sydney technician. There is a range of power-related problems that can cause AC failure and performance issues. An HVAC technician can diagnose the problem and are properly trained in how to work around high-voltage electricity.

Here are the electrical problems that can impact your air conditioner:-

Overloaded Circuit

When your AC trips the breaker, flipping the breaker back to the ‘on’ position isn’t the fix. Of course, doing so will get your air conditioner working again immediately. But, you’ll have to find what caused the breaker to flip in the first place.

Identifying the cause and fixing the issue can help prevent the problem from recurring and ensure that the air conditioner doesn’t pose a fire threat in your house. This usually happens when the air conditioner consumes more power than the system is designed to handle. This means any airflow blockages or usage changes that put extra strain on the system can cause the breaker to trip. In short, an overloaded circuit that’s when the tripper trips to prevent causing damages to the electrical appliances connected with it.

A clogged filter, blocked airflow in the condenser, and a faulty thermostat are some of the common causes of this problem. That’s why regular air conditioning maintenance Sydney is crucial as it helps to keep the system in good shape.

Wiring Issues

The wiring in your cooling unit can experience wear and tear like other electrical appliances. In case if there’s exposed wiring inside the system, it can lead to an electric short that can shut down the entire cooling unit. Also, the vibrations caused by the blower motor running can shake wires, leading to loose connections. Due to the problems with the wiring, the air conditioner can experience a surge of power when they start up and overload the wires. This can lead to shorts or even create a fire hazard inside the unit. If your air conditioner shuts off on its own after a power outage, call in a professional technician for inspecting and fixing.

AC Won’t Turn Off

If your cooling doesn’t turn off even when the set temperature is reached, there’s an issue with the electronic controls that requires immediate attention. The thermostat could be malfunctioning, or the sensor might have knocked out of position.
