7 Signs Your Air Conditioner Needs Repair

Air conditioners rarely fail without warning. Catching the early signs usually means a smaller repair bill and less time without comfort.

Warning signs to watch for

1. Warm air when set to cool — often a refrigerant, sensor or compressor issue.
2. Weak airflow — commonly blocked filters, a failing fan motor or duct problems.
3. Water leaking indoors — usually a blocked drain line or an iced-up coil.
4. Grinding, squealing or rattling — loose parts or worn bearings.
5. Musty or burning smells — mould build-up or an overheating component.
6. Error codes or short cycling — the system switching on and off frequently.
7. Rising power bills — the system is working harder than it should.

What to do

Switch the system off and book an inspection. Continuing to run a faulty unit can turn a small, inexpensive fix into a major repair.
