Common problem
Air Conditioner Not Turning On in Prospect
Nothing happens when you press the controller, and the house is heating up fast. Prospect homes call us about this fault all summer, and Prospect Air Conditioning gets a dead air conditioner running again, usually in one visit.

Why Your Air Conditioner Is Not Turning On in Your Prospect Home
A unit that will not start usually has one simple cause, not five. The trick is working through them in order, cheapest first, before anyone starts pulling parts off a wall.
Plenty of homes here are semi-detached pairs on tight inner-northern blocks, so the outdoor unit and its isolator sit in a narrow side passage and get forgotten. Start there before assuming the worst.
In detail
Likely Causes, Cheapest First
Power and Switchboard
A tripped breaker kills the whole system silently. Homes built through the 1940s to 1960s often still run original switchboards, and an aircon circuit that keeps tripping points to wiring that needs a proper look.
Controller and Settings
Flat controller batteries or a unit switched to heating mode fool plenty of people. Check the display and the mode before anything else.
Isolator and Wiring
The outdoor isolator switch can corrode or get knocked off. A burnt-out capacitor is the next step up and is a common, affordable fix.
Compressor Failure
A dead compressor is the expensive end of the scale. If the unit is old, air conditioning replacement often beats throwing money at a repair.
Get it sorted
Safe Checks Before You Call
A few checks cost nothing and solve a good share of no-start calls. Work through this list:
- Press the controller reset and replace its batteries.
- Check the switchboard for a tripped aircon breaker.
- Look at the isolator switch beside the outdoor unit.
- Confirm the unit is set to cooling, not heating.
If the breaker trips again the moment it resets, leave it off. Repeated tripping means a fault, not a nuisance, and forcing it back on makes things worse.
Do not wait on this
When a Dead Aircon Becomes an Emergency
A no-start on a 40-degree day is not a convenience problem. Elderly residents and young kids cop the heat first, and a house that cannot cool becomes unsafe by mid-afternoon.
We treat urgent calls accordingly, with 24/7 emergency availability and a Within-the-Hour Response where availability allows. If the unit shows error codes before it dies, our error codes page can tell you what the controller is trying to say.
How it works
How We Get Your Air Conditioning Running Again
- 01
Test Onsite
We trace power from the switchboard through to the unit and find where the circuit actually fails, rather than guessing at parts.
- 02
Quote in Writing
You get the fixed price before any work starts. No hourly rates, no bill shock, and no surprises when the invoice lands.
- 03
Repair and Verify
We carry common parts for the brands we service, including Daikin and Fujitsu, so most repairs finish same visit. Every fix gets tested under load before we leave.
All refrigerant and electrical work is carried out under ARC Licence L162586, the full RAC01 refrigeration and air conditioning authorisation.

Repair or Replace a System That Will Not Start?
Age decides this more than anything else. A capacitor on a six-year-old split system is a cheap fix, while the same symptom on a fifteen-year-old unit usually signals the start of a run of failures.
We will tell you straight.
Older homes hide causes.

Aircon Questions From Prospect Homes
Can I fix a dead air conditioner myself?
You can safely check the controller batteries, the circuit breaker and the isolator switch near the outdoor unit, but anything past that needs a licensed technician, because refrigerant and live wiring are not DIY jobs.
How fast can you get here?
We run 24/7 emergency availability across Prospect and the inner north, so urgent no-start calls get a Within-the-Hour Response where availability allows, and we prioritise homes with young kids or elderly residents.
Is a dead compressor worth repairing?
Often not. If the unit is past fifteen years or the repair costs a third of a new unit, we will say so honestly and quote a replacement alongside the repair so you can compare.
Do you quote before starting work?
Always. Fixed Upfront Pricing means you get the fixed quote before any work starts, so there are no hourly rates and no bill shock, whatever the fault turns out to be.
