If you want to get the most from your air conditioner and if you want your air conditioner to last for as long as it possibly can, you need to make sure that you are conscientious about maintenance. 

These common issues with air conditioners can cause your air conditioner to perform poorly when you need it the most.

Dirty filters

Filters that are clogged up and rarely changed significantly reduces the efficiency of your air conditioner. Airflow is restricted and your power bills will rise. The more you use your system the more often you will need to change your filters. If you have pets and they are prone to shedding, then your air conditioner will clog more often. 

Too much sun getting in

Too much sun getting inside your home will increase the temperature and cause your air conditioner to work harder than necessary. Keep your blinds and curtains pulled to reduce the amount of heat in your house. The less your air conditioner needs to work the longer it will last and the more efficiently it will run. To make sure there is no heat sneaking in around the perimeters of your windows and doors it’s a great idea to use weatherstripping.

What if my air conditioning unit is vibrating

This is most likely the on and off cycle of the compressor. It could also be the result of poor installation. To be doubly sure, check the owner’s manual and trace the installation instructions. If you are convinced that it is an installation problem then you should contact a specialist in home air conditioner repair in Sydney.


Smart thermostats are brilliant at controlling the temperature inside your home. But if you feel for any reason that the thermostat is not working as efficiently as it might then you should be checking that there is nothing affecting its performance. A common problem is thermostats placed in direct sunlight.


You should regularly vacuum the registers on your air conditioner to remove the presence of dust, dirt and if you have them, pet hair. Pay special attention to your lounges and soft furnishings. 


Because most compressors live outdoors you need to make sure that there’s a metre or two from plants and other structures. The same applies to anything overhead. Suitable clearance from branches or other structures above the compressor can also adversely affect performance.
