Why is my air conditioner not turning on?

Check whether the system has power. Confirm that the wall isolator is switched on, the controller or remote has working batteries, and the relevant circuit breaker or safety switch has not turned off. If the controller is blank or the indoor unit does not respond, do not open electrical covers. If the circuit breaker or safety switch turns off again after being reset, leave the system off and contact a licensed electrician or air conditioning technician.

Why is my air conditioner running but not cooling?

Check that the system is set to COOL mode and that the selected temperature is lower than the room temperature. Close external doors and windows, clean accessible filters, check indoor airflow, and ensure the outdoor unit is not obstructed. If the unit runs continuously without reducing the room temperature or cooling performance has suddenly declined, arrange professional testing.

Why is my reverse cycle air conditioner not heating?

Confirm that the system is set to HEAT mode and select a temperature above the current room temperature. Reverse cycle systems may briefly delay the indoor fan while the coil warms and may pause during normal defrost cycles. Check filters and outdoor airflow. Arrange a service if the system continues blowing cool air or cannot reach the selected temperature.

Why does my air conditioner temporarily stop heating in winter?

The system may be completing a normal defrost cycle. During defrosting, indoor and outdoor fans may stop while frost is removed from the outdoor heat exchanger. Heating should resume automatically. Arrange a service if defrosting becomes unusually frequent, lasts much longer than normal, or heating performance remains poor.

Why is the airflow from my split system or ducted vents weak?

Weak airflow can be caused by dirty filters, low fan speed, blocked supply vents, an obstructed return-air grille or incorrect ducted zone settings. Clean only accessible user-serviceable filters. If airflow remains weak, the indoor coil, fan, zone damper or ductwork may require professional inspection.

Why is one room not heating or cooling properly with ducted air conditioning?

Check that the room or zone is enabled on the controller and that its supply-air grille is open and unobstructed. Check the return-air filter and system settings. If one room remains noticeably different from the rest of the property, the cause may involve zone controls, a damper, damaged ductwork, air leakage or airflow balancing and should be professionally inspected.

Why is one indoor unit in my multi-head system flashing and not operating?

Check that all indoor units connected to the same outdoor unit are set to the same operating mode. Multi-head systems generally cannot heat one room while cooling another. If all indoor units are already set to the same mode and one continues flashing, record the flashing-light pattern and arrange a service.

Why does my air conditioner keep turning on and off?

Some cycling is normal with inverter air conditioners. Frequent short cycling may be caused by dirty filters, restricted airflow, timer settings, controller or sensor issues, incorrect system sizing, or electrical or refrigeration faults. Arrange a service if the system starts and stops every few minutes or cannot maintain comfort.

Why is water leaking or dripping from the indoor unit?

Turn the system off if water is dripping from the indoor unit, ductwork or ceiling. Possible causes include a blocked or damaged drain, failed condensate pump, restricted airflow, a frozen coil or another internal fault. Do not dismantle the unit or use chemicals in internal drains. Arrange professional inspection.

Is water or frost around the outdoor unit normal?

Some water beneath the outdoor unit and light frost can be normal during heating and defrost operation. Heavy ice that remains, water entering the building, hazardous drainage or leaks from unusual locations should be investigated. Do not chip ice from the coil or pour hot water over the outdoor unit.

Why is my air conditioner making an unusual noise?

Brief clicks and normal airflow sounds can occur during operation. New, loud or persistent rattling, grinding, scraping, squealing, buzzing or strong vibration may indicate a fan, motor, bearing, electrical or compressor-related fault. Turn the system off if the noise is severe or accompanied by a burning smell, poor performance or water leakage.

Why does my air conditioner smell musty, stale or like it is burning?

Musty or stale smells may be caused by dust, moisture or microbial growth on filters, coils, fans or drainage components. Clean accessible filters according to manufacturer instructions. A persistent burning, melting-plastic or electrical smell may indicate overheating or an electrical fault, so switch the system off and arrange professional inspection.

Why is my air conditioner remote control not working?

Replace the batteries, confirm they are installed correctly, point the remote at the indoor unit and check for obstructions. Check whether a timer, lock or controller setting is active and confirm the operating mode. Refer to the model-specific manual if the unit still does not respond.

What should I do when an operation light is flashing or an error code appears?

Record the full error code, controller message or flashing-light pattern before switching the system off. Note which units are affected and whether the problem occurs in heating, cooling or both. Do not repeatedly reset an unresolved fault. Provide the exact error code and model number when booking a service.

Why has Mitsubishi Electric Wi-Fi Control stopped working?

Check that the internet connection and router are working, the air conditioner has power and the Wi-Fi Control app is logged in. Re-pairing may be required after a router replacement, network name change, password change or network reset. Use the Mitsubishi Electric instructions for the specific adaptor.

Why has my air conditioning electricity use increased?

Higher electricity use may result from longer operating hours, extreme weather, very high or low temperature settings, dirty filters, blocked airflow, open doors and windows, poor insulation or conditioning more rooms. Arrange a maintenance check if electricity use rises significantly without a corresponding change in weather or usage and performance has also declined.

How often should I clean the filters and have the system serviced?

Follow the maintenance schedule in the manufacturer manual. For many wall-mounted Mitsubishi Electric systems, filters should be checked and cleaned approximately every two weeks during heavy use. A yearly professional service is a practical starting point for many residential systems, while commercial or heavily used systems may need more frequent servicing.

When should I stop troubleshooting and call a technician?

Stop using the system and arrange professional assistance for repeated circuit-breaker or safety-switch trips, smoke, sparks, persistent burning smells, electric shock or tingling, water near electrical parts, major indoor leakage, loud grinding noises, heavy ice that does not clear, recurring error codes or complete loss of heating or cooling after basic checks.

Why is my air conditioner not turning on?

How long does an air conditioning service usually take?

The time required depends on the type of system, its condition, and how many units need to be serviced. A straightforward residential split system will generally take less time than a larger ducted or commercial system. Climatic can provide a better indication when the service is booked.

Can Climatic service an air conditioner that you didn’t install?

In many cases, yes. If your air conditioner was installed by another provider, Climatic can assess the system and advise on its servicing requirements. Providing the brand and model details when booking can help the team prepare for the visit.

Do I need to do anything before the technician arrives?

It helps to make sure the indoor and outdoor units are accessible and that furniture, storage, or other items are not blocking the equipment. If you have noticed any unusual behaviour, noises, or performance changes, mention these to the technician when they arrive.

Will I receive information about the condition of my system after the service?

Yes. Climatic’s current servicing information states that technicians check and report on the unit's condition and can provide a written service report. Any issues identified or further maintenance recommendations can then be discussed with you.

Can Climatic create an ongoing servicing schedule?

Servicing can be scheduled quarterly, biannually, or annually depending on usage and environment.

How Often Should an Air Conditioner Be Serviced?

Most systems benefit from at least an annual service, though usage and environment affect the right frequency. Climatic custom-designs service schedules on a quarterly, bi-annual, or annual basis to suit each property's needs. Read the detailed guide on how often an air conditioner should be serviced from an Australian perspective.

What Are the Signs an Air Conditioner Needs Attention?

Your system may need professional attention sooner than its scheduled service. Common indicators include reduced airflow, unusual odours or noises, inconsistent temperatures across rooms, or a system that runs continuously without reaching the set temperature. If any of these apply, the air conditioner troubleshooting page can help you assess next steps, or call the team directly.

Do Technicians Need to Be Licensed to Service My System?

Yes. In Victoria, technicians who handle refrigerants must hold a current ARCtick licence, and installers must hold a Plumbing Industry Commission licence. Engaging an unlicensed operator can void manufacturer warranties and create safety and compliance risks.
