Our technicians recommend servicing air conditioning units at least once a year, with periodic checks up to four times a year. We can build a service plan to match your financial requirements while keeping your system working reliably based on the age, size, and use of your system.

As a general practice, you should clean air conditioner filters every two weeks if it’s an indoor unit. However, there are a few exceptions.

Cleaning filters more often is recommended in dusty settings. The same is the case if you have pets in your house. Overall, the bottom line is that cleaning your air conditioner’s filters is the most crucial maintenance you can perform.

When your air conditioner is over ten years old, you should consider replacing it, especially if you notice any of the following symptoms:

  • Frequent failures
  • Excessively high power costs
  • Changing humidity in the air-conditioned room
  • A costly repair.

For a better understanding, you can also call us. We will analyse your present unit and draw out your next steps.

The first step is to keep the surrounding grass and plants away from the outdoor compressor unit and to brush away dust, leaves, and cobwebs regularly. Then, use a vacuum cleaner and remove dust from the air intake.

However, we do not advocate opening the machine to clean its interior components; leave it to an expert team like ours!

You can reach us in two ways. You can either call us on 02 4061 7050 or email us at If you want to test the waters first, you can also request a free quote for your requirements. This will help you reach a decision.

First, clean the unit’s air filters regularly. Secondly, replace the air filters as and when required without delay. These two maintenance practices will improve the energy efficiency of your air conditioning system to a good extent.

Also, use a programmable thermostat to optimise temperature settings and save energy use. Schedule yearly professional maintenance to keep the system functioning well and to detect possible problems early.
