Air Conditioner Running but Not Cooling — Who Do I Call?

If the air conditioner runs but the room stays warm, check cooling mode and clean accessible filters as the manual instructs. If that does not help, book an air-conditioning technician to inspect it. The local listings below show businesses to ask; optional answers describe your system without guessing the fault.

Smoke, sparks, a burning smell or water near electrical fittings? Stop using the unit; call 000 for immediate danger.

    Who inspects an air conditioner that will not cool?

    An air-conditioning service business can inspect a system that powers on but does not cool. Tell it whether the system is split, ducted, window or portable, and whether airflow is weak or simply warm. Do not assume it needs refrigerant or a replacement compressor; the same symptom can have different causes.

    The Australian Government recommends routine filter cleaning according to the manual and regular servicing by a licensed technician. Refrigerant-handling work requires an ARC authorisation, and states may have separate electrical or trade licensing requirements. Confirm the business handles your equipment and holds the relevant credentials before booking.

    What can I check before requesting service?

    Check the remote or controller is set to cooling rather than fan or heating, close doors and windows as appropriate, and inspect an accessible filter using the manufacturer’s instructions. Do not open sealed panels, handle refrigerant lines or work on wiring. Note the model, age if known, error codes and when it last cooled normally.

    If the unit leaks near electrical fittings or shows smoke, sparks or a burning smell, stop using it and keep clear. Call 000 for immediate danger. An ordinary quote request does not arrange an urgent response.

    Compare inspection and repair scopes

    Ask whether the first visit covers diagnosis, cleaning, testing and a written repair recommendation, and what parts or additional work would cost. A service quote should distinguish maintenance from a fault repair and explain whether replacement is being proposed and why.

Confirm repair scope, authorisations and service area with each business. Select eligible businesses and send one reviewed request with your optional answers and suburb.

    Good questions. Plain answers.

    Who do I call if the air conditioner runs but does not cool?

    Ask an air-conditioning technician who services your system type. Confirm ARC refrigerant-handling authorisation and any state licence required for the proposed work.

    Does warm air mean the unit needs refrigerant?

    Not necessarily. A technician should inspect the system before identifying the fault or recommending a repair.

    Can I clean the filter myself?

    Many systems have accessible filters that the owner can clean according to the manufacturer’s instructions. Do not open sealed equipment or handle wiring or refrigerant.
