Perth Air Conditioning Service, Repairs & Maintenance

Air conditioning servicing begins with a thorough inspection of your air con system to assess its condition, performance and airflow. One of our qualified technicians will check key components, including the indoor and outdoor units, identify signs of wear or damage, and look for issues affecting the system’s heating, cooling, or energy efficiency.

If a fault is found, our technician will diagnose the cause and recommend the most suitable air con fix. The required air conditioner repair may involve replacing worn parts, repairing electrical or mechanical components, clearing airflow obstructions, checking for a gas leak, or resolving system faults that prevent the air conditioner from operating properly.

Keep your system running reliably and book an air conditioning service with Ford & Doonan today.

Ford & Doonan recommends having your air conditioner professionally serviced at least once a year, regardless of how frequently you use it. Annual air conditioning system servicing helps maintain performance, improve energy efficiency and prevent minor issues from becoming more costly repairs.

Ford & Doonan recommend cleaning and/or replacing your filter once every six to twelve months and this can be done at home following our DIY videos on YouTube:

Air conditioning servicing costs vary depending on the type of system, its condition and the maintenance or repair work required. Ford & Doonan offers Perth air conditioning service and maintenance options for residential and commercial systems. If your system was installed by one of our branches, please contact them for servicing. Alternatively, contact the Head Office Service Department for information relevant to your air conditioning unit.

The time required depends on the type, size, condition and accessibility of your air conditioning system. A straightforward maintenance service usually takes less time than diagnosing an intermittent fault or completing air conditioning repair work. The technician will provide more information after reviewing your service request.

Common signs include:

• Reduced heating or cooling
• Weak or restricted airflow
• Unusual noises or vibrations
• Unpleasant or unusual odours
• Higher energy use or electricity bills
• Fault codes
• Water leaking or excessive condensation
• System that frequently turns itself on and off

You should also arrange a service or repair if the air conditioner will not power on or is no longer operating reliably.

Regular servicing helps your air conditioner operate more efficiently by identifying performance issues and reducing unnecessary strain on the cooling system. A properly maintained and energy-efficient unit uses less energy to reach and maintain the desired temperature.

Yes. Ford & Doonan services most refrigerated air conditioning systems, including many units installed by other air conditioning contractors. Availability varies during peak demand periods, when priority is given to systems originally installed by Ford & Doonan.

Ford & Doonan services a wide range of air conditioning brands and models. Our local technicians maintain most refrigerated systems regardless of their age, brand or original installation company, although support depends on the system and the availability of replacement parts.

Whether an older air conditioner is worth repairing depends on its condition, efficiency, repair requirements and the availability of suitable parts. A technician will assess the system and help you compare the price of air conditioner repair with the longer-term value of a replacement or new system.

Your air conditioner may not be heating or cooling properly for several reasons. Dirty filters, blocked vents or dust building up inside the system can restrict airflow and force the unit to work harder. Low refrigerant levels, faulty sensors, electrical problems or damaged components can also prevent it from reaching the desired temperature.

For ducted systems, damaged or poorly sealed ductwork may allow conditioned air to escape before it reaches each room.

Evaporative systems rely on airflow and water, so poor performance may be caused by blocked cooling pads, a faulty water pump, inadequate ventilation or humid weather.

Please note, Ford & Doonan no longer service or maintain any residential evaporative air conditioners.

Regular servicing helps identify the cause, restore performance and prevent minor faults from becoming bigger repairs.

Unusual noises often indicate that part of your air conditioning system needs attention. Rattling could point to loose panels or components, while buzzing could indicate an electrical fault. Grinding or squealing noises often indicate worn motor bearings, belts, or other moving parts. Clicking during start-up is usually normal, but repeated clicking could signal a faulty control or electrical component.

Turn the air conditioner off if the noise is loud, persistent or accompanied by reduced performance, unusual smells or weak airflow. Avoid repeatedly restarting the system, as this could worsen the fault. Record when the noise occurs and arrange an air conditioning service so a qualified technician can inspect the unit and recommend appropriate repairs.

Servicing helps improve the cleanliness of the air moving through your system by addressing dirty filters and internal build-up. Clean filters and coils improve airflow and reduce the amount of dust and unpleasant odours circulating throughout your home. For refrigerated systems, servicing can also identify excess moisture, mould growth or drainage issues that may affect air quality.

We recommend booking an air conditioning service in Perth between April and September so your air conditioner is inspected before peak summer demand.

Servicing your air conditioner before summer also helps improve energy efficiency and reduces the risk of an unexpected breakdown during hot weather. Booking early gives you more time to complete any recommended air conditioning repairs before you need to use the system regularly.

Check your air conditioning filters every three to six months and clean them when dust or debris is visible. Homes with pets, smokers, high dust levels or frequent air conditioner use may require more regular cleaning, often monthly. Replace disposable filters according to the manufacturer’s instructions, as these are not designed to be washed or reused.

Ducted and split system air conditioners have different filter requirements, so refer to your system manual or ask a qualified technician for guidance.

First, check that the air conditioner has power and that its circuit breaker has not tripped. Review the controller settings to confirm the system is set to the correct heating or cooling mode and temperature. If it is safe to do so, inspect the filter for dust or airflow restrictions and check whether the indoor or outdoor unit displays a fault code.

If the air conditioner still doesn’t work, switch it off and avoid repeatedly restarting it, as this could place further strain on the system. Record any fault codes, unusual noises, smells or changes in performance before submitting an air conditioning repair request. These details will help our qualified technician diagnose the fault and determine the appropriate repair.

Regular air conditioning servicing is important for Perth homes that rely on consistent, efficient heating and cooling throughout the year. Even when your system appears to be working normally, worn components, restricted airflow and minor faults affect its performance and potentially lead to more expensive repairs.

You should book a service if your air conditioner is not heating or cooling effectively, will not turn on, is making unusual noises or is no longer performing as well as it once did. Routine air conditioning maintenance also helps optimise performance, reduce energy use and lower the risk of an unexpected breakdown during Perth’s hottest months.
