Who Repairs Heat Pumps In Brisbane : It Isn’t A Plumber
Who repairs heat pumps?
Licensed HVAC technicians and electricians with refrigeration certification repair heat pumps. These professionals are trained to diagnose faults in electrical circuits, control boards, compressors, and refrigerant systems. Unlike plumbers or basic installers, only certified technicians have the legal authority and technical expertise to safely service and repair heat pumps.
Heat Pumps Are Rapidy Gaining Popularity But What Happens When They Break?
Heat pumps are becoming the go-to system for year-round climate control. Efficient, quiet, and compact, they’re being installed in new homes across Brisbane at record rates. But here’s what most people don’t realize: the person who installs your heat pump (usually a plumber) isn’t qualified to repair it when something goes wrong.
And that’s a problem.
Installation ≠ Repair
Installing a heat pump typically involves mounting units, routing piping, and setting up basic connections. Many plumbers and HVAC installers can do this under a refrigeration and plumbing license.
But when that heat pump starts short-cycling, leaking water, blowing warm air in summer, or tripping your power?
That’s not a plumbing issue. That’s:
- A high-voltage electrical fault
- A refrigerant pressure imbalance
- A control board error
- A sensor calibration problem
And all of those require a licensed technician trained in electrical diagnostics and refrigeration mechanics.
The Hidden Complexity Inside a Heat Pump
Here’s what’s actually running inside your system:
- Compressor circuitry
- Reversing valves for switching modes
- Defrost control boards and sensors
- High/low refrigerant pressure lines
- Variable speed drives
- Thermostatic expansion valves (TXVs)
Plumbers don’t train for this. Licensed heat pump technicians do. And only those with the correct electrical license and ARCtick refrigerant handling certification can legally open the unit and fix it.
The Risk of the Wrong Fix
When an unqualified person tries to diagnose or “service” a failed unit, here’s what often happens:
- Refrigerant gets topped up without leak detection
- Electrical shorts go unnoticed, causing bigger faults
- Component failures get misdiagnosed as thermostat problems
- Warranty is voided due to unauthorized work
You risk turning a minor fault into a full-system breakdown—or worse, creating a safety hazard in your home.
