My air conditioner is making a strange noise. Is this normal?
Air conditioners, unfortunately, aren't silent machines so some noises that may seem unusual are normal.
All units have a minimum requirement for the amount of pipe length between the indoor unit and outdoor unit and if that has not been met at the time of installation it may cause the unit to make louder than normal or abnormal operating noises.
You should also take into consideration the location of where the outdoor unit has been installed and if proper isolating mounts have been used. This will help to minimise any noise or vibration that might be transferred through the outdoor unit to the indoor unit.
If you are concerned about the noises your unit is making, you can contact Fujitsu General Assist on 1300 364 484, or record the noise and send it through to [email protected]
There is an odour coming from my air con. What should I do?
If you are experiencing an odour you suspect is coming from your unit, firstly check to see if your return air filters are clean and if not, we suggest removing and cleaning them to see if that resolves the issue.
You should also take into consideration the location of your unit. Your air conditioner draws in air from the space it is operating in which means that smells such as cooking food can occur if the unit is installed in, or nearby, a kitchen.
Another possible reason for potential odour is the moisture that condensates on the indoor coil can absorb smells from the surrounding environment. If it does not drain away properly and sits in the drain tray for too long, it can start to smell.
It is recommended that you have a service carried out on your air conditioner every 12-24 months (depending on the usage and environment) which can include a coil and drain tray clean/treatment.
There is water dripping from my air con, what should I do?
You should check to see if your return air filters are clean and if they aren't, you should remove and clean them before re-installing them. Consideration also needs to be given to the environment condition, humid conditions may result in condensation dripping from the indoor unit (usually from the louvers).
Blocked drains can also cause water to drip from the unit and if you think this may be the case you should get your unit looked at by a professional. You will also find that the outdoor unit will drip water when using the air conditioner in heating mode which is completely normal from the outdoor unit coil condensation.
Drain plug kits are provided for the outdoor units in the box when new, so should be used at the time of installation if there is a chance of water dripping onto an area you would like to keep clear.

How can I tell if I have a refrigerant leak?
If the air conditioner feels like it is lacking in performance compared to the previous operation, this may be an example of potential refrigerant loss.
To confirm if there is a refrigerant leak, the unit should be inspected by a qualified refrigerant and air conditioning technician. Some quick troubleshooting tips before you have the unit looked at by a professional include checking the filters to ensure they aren't blocked, making sure the unit is set to the right mode and set temperature for the system to turn on, and if you have access to the outdoor unit, checking that it is operational.
It is recommended that you contact your installer in the first instance if you believe there is a refrigerant leak to do a full check over the system and installation.
To arrange a service call, you can then contact our Fujitsu General Assist service team on 1300 364 484 or find a recommended Service Agent at fujitsugeneral.com.au/fujitsu-service. If you are exploring an external Service Technician, please ensure they registered and licensed with ARCtick.
How do I organise a service for my air conditioner?
What happens if piping is less than the minimum recommended length (3 metres/5 metres)?
If the product is installed with less pipework than the minimum requirement specified by Fujitsu General engineers, noise and/or vibration issues may occur and also the system may not perform as well as it is designed to. Fujitsu General will not cover warranty claims for issues caused by units not being installed in accordance with their manuals.
Does the outdoor unit need to be installed on a concrete slab or on brackets?
The outdoor unit of your split system does not have to be installed on a concrete slab or brackets. However, having the outdoor installed directly on the ground may cause excessive vibration and/or noise without the use of a vibration eliminator. There are many different options for installing your outdoor unit. You should discuss your requirements with your installer to find the most suitable arrangement for your home.
Can I reuse the piping which is already installed for my old air conditioner?
It is not recommended to reuse the same piping and cable for new units as different systems have different piping and electrical requirements.
Can I reuse the ducting which is already installed for my old ducted air conditioner?
Ducting is sized and placed according to the house layout and the desired air distribution. As long as the ductwork meets the requirements of both the unit and the air conditioned space then it is fine to keep the old ducting if it is in good condition. This would need to be confirmed with your air conditioning installer for your particular requirements.
