Who We Are

How We Repair Heaters in Hornsby

When we come out in Hornsby, we diagnose the real fault before quoting, not swap parts and hope. Every repair covers these four steps, with a fixed price up front and a written summary after.

Full Fault Diagnosis

We run your Hornsby system through a complete diagnostic, read any fault codes, and find the true cause instead of chasing the symptom. You get a plain-English explanation and a fixed repair price before we begin.

Ignition & Gas Component Check

When a Hornsby heater gives no ignition, a dropping pilot or short-cycling, the igniter, flame sensor, gas valve or board is normally to blame. We test each component, confirm the fault and replace it with quality parts.

Carbon Monoxide Safety Test

We carbon monoxide test every Hornsby gas heater we repair and check the heat exchanger for cracks. Your family's safety comes first, so an unsafe appliance never gets left running.

Performance Test & Sign-Off

Once repaired, we run full heating cycles, check airflow and outlet temperatures, and confirm your Hornsby system is heating correctly and operating safely before we pack up.

Not Sure If It's Worth Repairing?

If your heater won't ignite, blows cold, smells of gas, keeps shutting off or is flashing an error code, do not tough it out in the cold. Call us and we will diagnose the fault and give you an honest repair-or-replace recommendation, with no pressure either way. If we ever detect a gas or carbon monoxide risk, we shut it down and tell you on the spot.

The usual culprits are a failed igniter, a faulty flame sensor, a stuck gas valve or a control board fault. Our Hornsby technicians diagnose the exact cause on site and give you a fixed repair price before starting.
In most cases, yes. Many repairs are finished in one visit and our vans carry common parts. If a specialist part needs ordering, we will tell you upfront and book the return quickly.
Short-cycling usually means an overheating safety trip, a dirty flame sensor, a blocked flue or a failing fan. We find which it is, fix the cause rather than reset it, and confirm it runs a full cycle before leaving.
A dusty smell on first use of the season is normal and clears quickly. A persistent burning, chemical or gas-like smell is not. Turn it off and book a repair. We will test for carbon monoxide and inspect the heat exchanger as part of the visit.
Yes. Alongside gas ducted and wall furnaces, we repair hydronic systems (pumps, valves, boilers), gas log fires and reverse cycle units, all by licensed technicians with a full test before sign-off.
