Troubleshoot Your Aircon: 5 Common Reasons Why Your AC Won’t Turn On

 In Tips

A working air conditioning unit has become an integral part of Australian living, as much as it has become an absolute necessity to the success of any business.

When your air conditioner stops working at the office or a large scale shopping centre such as Westfield Carousel, not only do staff members suffer so do your customers.

Unfortunately, in these circumstances, the issue is not so easy to diagnose and will generally require the help of a professional to repair and restore the system.

However, when your air conditioner breaks down at home, it might be a simple fix that you can do. But it can also be a major problem that will require a technician to come out and diagnose and repair.

Here are some common reasons why your air conditioner won’t turn on.

 

1. Has the unit been unplugged?

“Have you tried turning it off and on?” I am sure we’ve all heard this at some point in time, whether on the phone to your internet provider or calling up the IT department at work, but you’d be surprised how often this can happen. It may have been partially dislodged while cleaning or the kids playing.

 

2. When was the last time you cleaned the filters and coils?

Neglected AC units which have not been maintained and cleaned is a common reason why air conditioners break down. Built-up dirt and dust in the filters and coils can cause the compressor or fans to stop working. 

This is why it is important to clean your AC unit annually, or every 3 to 6 months if you start to notice a build-up. We recommend cleaning them before the start of summer and winter where they are going to be used the most to ensure it is running efficiently all year round.

 

3. Malfunctioning thermostat

If your air conditioner is not blowing out any cold air it can either mean the there is an issue with the positioning of the sensor or your system needs a service. Either way, you may have to call a technician out to come and have a look at your AC unit. For the time being, check the thermostat setting on your remote. If it says ‘on’, then the thermostat function should also be set to ‘cool’. Try lowering the temperature on the remote.

 

4. Ice forming inside the unit

Ice forming is another common reason why your AC system has stopped working. When you don’t clean your air conditioners filters, dust and dirt starts to build up and eventually, enough of it will create a blockage. This blockage prevents your system from being able to ‘breathe’, resulting in the formation of ice. 

This is generally quite an easy fix and one you can DIY without the need to call a technician. Turn off your system for a few hours to allow the ice to melt completely, you may want to put a towel or bucket underneath to collect the melted water. 

Once all the ice has melted off, remove the filters and give them a good clean. If your system continues to freeze over it might be time for a service. 

 

5. Tripped circuit breakers and blown fuses

Another easy way to identify why your ac system won’t turn on is to check your fuse box for your home. Double-check to see if you haven’t blown a fuse or tripped a circuit breaker or safety switch. Replace the fuse or switch the safety switch back on and try turning on your AC unit. 

If it doesn’t turn on, you’ll most likely need to contact a licensed technician. If the AC system turns on but soon trips again moments shortly, there might be a problem with the wiring in your home. 

 

Keep your air conditioner running efficiently all year round

To ensure your AC system is running optimally all year round, it’s normal to have to have it regularly serviced and maintained for cleanliness, blockages and the odd repair by a licensed technician.

Regular Air conditioning maintenance and servicing of both residential and commercial AC systems not only increase its efficiency, it can also prolong the unit’s lifespan by up to 10 years.
