Air Conditioning Troubleshooting Guide – Part 1

Common Problems with your AC and the solutions

Air conditioners are a complex piece of engineering, and this means that there can be many reasons when they may not operate as intended or worse – not at all. But before you call the air conditioning repair specialists in Brisbane or the Sunshine Coast at H&H Air Conditioning for a system that doesn’t seem to be operating at its peak, we’ve put together a few common problems and their solutions in part 1 of our handy guide. ISSUE

#1: My Air Conditioner is not blowing cold air


•    Set the temperature (thermostat) to a lower temperature than the ambient temp.

•    Filter is dirty and needs cleaning or replacing. Here is our guide to cleaning air conditioning filters.

•    System is set to fan or heating mode. Use system’s auto mode to blow correct air suited for the season.

•    Low refrigerant pressure or not enough refrigerant. Call a refrigeration and air conditioning professional.

•    Outside condenser unit is dirty. Remove debris caught in fins and weeds and clutter obstructing the outside unit.

ISSUE#2: The Air Conditioner struggles to cool the home, despite high use.


•    Leaks in ductwork.

•    Are windows or doors being left open in the area you desire to be cooled?

•    Outdoor unit is not positioned in best place to receive maximum air flow.

•    System has the wrong capacity for the space you need cooled.

ISSUE# 3: System won’t turn on at all – and there are no lights on the system


•    System is not plugged in at the power outlet

•    Batteries in the remote need changing

•    Power switch is not turned on at the unit

•    Circuit breaker has tripped. Reset at main switchboard to test operation.

•    Internal fault that needs to be inspected.
