5 Common Signs Your Air Conditioner Needs Servicing – And What to Do About It

GT HVAC & Electrical

 

When Melbourne temperatures soar, the last thing you want is an air conditioner that’s not doing its job. Whether you’re in Mornington Peninsula, Yarra Valley, Melbourne CBD, Heidelberg, Alphington, or surrounding suburbs, knowing when your system needs professional attention can save you from costly breakdowns, high energy bills, and uncomfortable days indoors.

 

At GT HVAC & Electrical, we help homeowners and businesses stay cool with expert air conditioning servicing. Here are five of the most common signs your air conditioner needs servicing—and what you should do next.

 

1. Weak Airflow or Inconsistent Cooling

If your air conditioner isn’t pushing out strong, consistent airflow, it may be a sign of:

  • A blocked or dirty air filter

  • Issues with the ductwork

  • A failing blower motor

What to do:

Check and replace your filter if it’s clogged. If the issue persists, it’s time to book a professional inspection. Our technicians can quickly diagnose airflow problems and restore your system’s performance.

 

2. Strange Noises or Vibrations

Hearing rattling, grinding, or buzzing sounds? These are not normal and could indicate:

  • Loose internal components

  • A failing motor or fan

  • Electrical issues

What to do:

Turn off the system and call in a technician. Continuing to run a noisy unit could lead to more serious (and expensive) damage. Our team at GT HVAC & Electrical can inspect and repair your system before things escalate.

 

3. Unpleasant Odours

A musty or burnt smell when your air conditioner is running can signal:

  • Mould or mildew inside the system

  • Burnt-out wiring or insulation

  • Clogged drain lines

What to do:

Unpleasant smells are both a health and safety concern. A thorough clean or internal inspection may be required. We offer HVAC cleaning services across Heidelberg and the broader Melbourne region to keep your indoor air fresh and safe.

 

4. Sudden Spike in Energy Bills

If your energy costs have jumped and you haven’t changed how often you run the aircon, your system may be operating inefficiently.

 

What to do:

Schedule a system check-up. Servicing your air conditioner regularly helps maintain optimal efficiency and can significantly reduce energy consumption and running costs.

 

5. Water Leaks or Excess Moisture

Puddles forming around your indoor unit? That’s usually a sign of:

  • A blocked condensate drain

  • Refrigerant leak

  • A broken condensate pump

What to do:

Water leaks can damage flooring and walls, and may lead to mould growth. Don’t ignore it—book a service immediately to address the underlying cause and protect your home.
