When the weather warms up, the last thing you need is your air conditioner playing up and not working correctly. Regular servicing is key to keeping your system running efficiently, but how do you know when it's time to call in the pros?

Here are the top 5 signs your air conditioner needs a service:

1. Weak or Warm Airflow

If your air conditioner is blowing warm air, or the airflow feels weak even at full blast, it’s a clear sign something’s not right. This could be caused by a clogged filter, a refrigerant leak, or a more serious internal issue. Either way, it’s time to have it checked out.

2. Unusual Noises

Air conditioners should run quietly in the background. So, if you're hearing grinding, rattling, buzzing, or banging, it’s more than just annoying - it’s a warning. Strange noises could mean loose components, motor problems, or debris inside the unit.

3. Bad Smells

Foul or musty odours coming from your AC unit could be a sign of mould or mildew in the system, especially around the ducts or filters. A burnt smell might indicate electrical issues. Either way, a service can clean things up and keep your air fresh and healthy.

4. Increased Energy Bills

If your energy bills are creeping up without a clear reason, your air conditioner might be working harder than it should. A struggling unit uses more power to keep your home cool, something a quick service could fix by improving efficiency.

5. Frequent Cycling On and Off

All air conditioners cycle on and off to regulate temperature, but if yours is doing it too often or erratically, that’s a problem. It might be a thermostat issue or a sign the system is overheating. A professional check-up can get it sorted before it turns into a bigger fault.

Why Regular Servicing Matters

Getting your air conditioner serviced at least once a year can:

Improve efficiency and performance
Extend the lifespan of your system
Lower your energy bills
Improve indoor air quality
Prevent unexpected breakdowns
