The Australian summer is such a fun time of the year. But when your air conditioning does not work it can be a nightmare. Sweltering nights, tossing and turning in bed is no fun at all. The AC has become a necessity in everyone’s home. At Glenco, we provide installation, servicing and maintenance for both residential and commercial air conditioning systems. 

In this article, we will discuss some of the common reasons why your air conditioning does not work. 

Inadequate Maintenance

Like most things in life, it is important to do regular maintenance to prevent issues from occurring. It’s no different when taking care of your air conditioning unit. So, let’s discuss some of the common maintenance issues: 

Clogged Filter

If you find your AC not blowing out much air it could be a clogged filter. This is a safety feature to prevent overheating and damage to the motor. If you feel comfortable checking and cleaning it yourself then go ahead. Otherwise, call a qualified air conditioning technician to have a look. 

Ice Build-Up

An ice build-up may result from dirty coils or filters. Give your coils and filter a clean to see if this fixes the problem. You will need to run your AC with just the fan blowing to melt the ice first. If that doesn’t fix the problem, it may be from low refrigerant levels which we will discuss later. 

Dirty Compressor

Over the years, dirt, leaves and other debris can build up around your compressor. It is important to clean it regularly to keep your AC in tip-top shape. We recommend that you leave this cleaning to the professionals. They will do a thorough job and can perform any other maintenance needed. 

Power Issues

Have you checked it’s plugged in? Such a basic question but sometimes it reveals  the answer to your AC problems. Make sure the unit is properly plugged in and the power cord is intact. If this doesn’t solve the problem, then it could be that your AC has blown a fuse or tripped a breaker. 

Electric Control Failure

Switching your air conditioner on and off frequently can lead to the compressor and fan controls wearing out. The wires and terminals in your system can also corrode. It is important to call in a professional AC technician to check this out. 

Thermostat Sensor Problems

If you find your AC still isn’t blowing out cold air it could be a simple thermostat issue. Try turning your unit to the coolest setting and see if this works. You can also check that the wiring going into the thermostat is intact. If you’re using a remote- try replacing the batteries. 

Drainage Problems

Air conditioners work by removing moisture from the air. This moisture will typically drain out of a hose or pipe. The hose or pipe can become clogged with algae. If this occurs your unit will stop working, again as a safety feature to prevent damage. You can clean the drainage system yourself with a mild bleach solution. Sometimes it may require replacing. 

Refrigerant Leaks

If your air-conditioning unit is low on refrigerant, it could mean there is either a leak or it was undercharged when installed. Refrigerants do not deplete over time. If there is a leak you will need a trained technician to fix it. They will be sure to put the correct amount of refrigerant in the unit. It is important to charge your unit with the exact amount of refrigerant the manufacturer specifies. This will lead to maximum efficiency. If you think your unit is leaking, call a professional immediately as it is also harmful to the environment.
