Common problem

Air Conditioner Not Cooling in Prospect

An air conditioner that runs but does not cool is the most common fault we get called for in Prospect, and it always gets worse right when the heat peaks. Prospect Air Conditioning diagnoses the real cause onsite, then gives you a fixed price before any repair starts.

Safe Checks Before You Call

Check the filter

Pull it out and hold it up to the light. If no light comes through, clean or replace it and see whether the cooling recovers.

Check the settings

Make sure the controller is actually set to cool, not fan or heat, and that the temperature sits below the room reading.

Check the outdoor unit

Clear away leaves and make sure nothing is blocking the airflow around it.

Do not wait on this

When Cooling Problems Need a Technician

Call us if the filter is clean and the settings are right, because the fault is now inside the refrigerant circuit or the electricals.

Book urgently if the unit is tripping the switchboard, icing up, or running warm during a heatwave. Those faults only ever get more expensive left alone.

We carry a full ARC refrigeration and air conditioning licence, so the diagnosis and any refrigerant work are done legally and properly.

Call and we will tell you honestly how fast we can get there.
