Wondering if your system is due for some maintenance? Here's our quick guide.
Obviously, if your air conditioning system becomes inoperable a service call is required. However, more often there may be signs that your system is not operating efficiently that are less apparent. If you are experiencing any of these, we recommend you book a service with one of our qualified technicians. We also suggest booking before the peak summer season when demand is at its highest.
If your bills are increasing unexpectedly, your system may be working harder and less efficiently to maintain the same temperature.
If your system loses the ability to regulate temperature, often failing to match your thermostat settings. This is more typical in older type systems.
Odours often indicate a need for filter replacement or at a minimum a thorough cleaning due to dust and bacteria. Grinding or loud noises typically point to issues with internal components like fans.
Dripping water coming from outdoor units is completely normal, however, moisture build-up inside your home or excessive water leaks outside suggests repairs or maintenance is necessary.
If you air conditioning system unit is not blowing enough air despite a higher fan setting, there may be an underlying issue with the compressor.

Common questions
It depends on the type of system. As a guide, a standard yearly service is $225 for a wall mounted split system, $260 for a single storey ducted evaporative unit, $305 for ducted reverse cycle, and $260 for ducted or inbuilt gas heating. All prices include GST and cover one unit. If you have more than one system at the property, extra units are charged from $125 each. We confirm the exact price when you book.
Our technician cleans and checks the return air filter, tests the compressor and motor currents, checks the refrigerant levels, cleans the indoor coil and clears the condensate drain, checks all electrical connections and controls, tests the unit for noise and vibration, and cleans the outdoor unit. You get a written report on the unit's condition and any repairs we recommend.
Booking times vary by system and season. Evaporative, split and ducted reverse cycle services are usually 5 to 7 days, and gas heating around 7 to 10 days, or longer through winter when demand is highest. If it is urgent, call us and we will do our best to fit you in sooner. Click here to view current wait times and book a service.
