Air Conditioner Might Not Start After Winter: What’s Behind It?

September 3, 2025

As summer creeps back in, some Gold Coast homeowners are caught off guard when their air conditioner might not start after winter. Months of dust, moisture, or even pests can quietly affect performance. While basic checks can help, only preventative maintenance ensures your cooling is reliable, especially with trusted air conditioning Gold Coast experts nearby.

5 sneaky reasons your air conditioner might not start after winter

Several factors can affect an AC system after months of inactivity:

  • Tripped circuit breaker: During startup, an AC draws a high amount of electricity. Voltage fluctuations or power surges can trip the breaker, cutting power to your unit.
  • Clogged air filters: Dust and debris often accumulate during winter, blocking airflow and forcing your system to work harder than it should.
  • Low refrigerant levels: Leaks may have developed over time, reducing the cooling capacity. If your AC isn’t cooling effectively, this could be the reason.
  • Damaged wiring: Moisture or even pests can damage wires, leading to startup failures.
  • Frozen or dirty coils: Dirt buildup or lingering moisture can freeze the evaporator coils, preventing the system from operating normally.

DIY lifesavers when your system refuses to start

Before calling in a technician, you can check a few things yourself:

  • Reset the circuit breaker: If your AC has no power, try resetting the breaker switch.
  • Check the thermostat settings: Ensure it’s set to “cool” mode and the temperature is appropriate.
  • Inspect for loose wires: If you can safely identify disconnected ends, tightening them may restore function.
  • Clean or replace filters: Fresh filters improve airflow and reduce strain on the system.
  • Check the drain line: A blocked drainage pipe can trigger safety shutdowns. Clearing it may solve the issue.

These steps often resolve minor problems. However, if your air conditioner still won’t start, it may point to deeper system issues.

When your air conditioner might not start after winter, it’s time to call the pros

Certain signs suggest that DIY efforts won’t be enough:

  • Persistent power failures: If the breaker continues to trip, internal wiring should be inspected by an expert.
  • Refrigerant leaks: Only licensed professionals can safely detect and refill refrigerant gas.
  • Strange noises: Loud humming, rattling, or buzzing usually indicate compressor or motor issues.
  • Weak airflow: Even after filter cleaning, poor airflow may mean blockages or failing components.
  • Frequent shutdowns: Continuous on–off cycling suggests deeper mechanical or electrical problems.
