Mornington Peninsula, Bayside & Greater Melbourne
Whether your solar panels have developed a leak, your heat pump is throwing fault codes, or your gas heater won’t fire up — our technicians have the skills and parts to fix it fast.
From fixing leaks to repairing bird damage, we ensure your solar system is performing at its peak.
Expert troubleshooting and maintenance for all major brands. We focus on compressor issues, refrigerant leaks, and flow rate analysis to keep your heat pump running efficiently.
We ensure your gas system is safe and operational with comprehensive checks and repairs for pilot lights, burners, and heat exchangers.
We restore automated precision by repairing or replacing faulty digital thermostats and solar controllers with genuine, high-quality components.
We fix the "heart" of your system to ensure optimal flow and pressure, preventing your heater from overheating, stalling, or causing system errors.
Recognising these early can save you from costly repairs down the track.
This typically occurs when a sensor is faulty or miscalibrated, or the system is struggling with flow issues. We run full diagnostics to check for system faults, recalibrate your digital controls, and precisely balance your operating pressure to ensure the reading on your screen matches the actual warmth of the water.
Visible leaks often signal a perished seal, a cracked manifold, or a solar collector that has reached the end of its life. We perform pressure tests to pinpoint the leak and stop water waste before it causes further damage.
Your system is likely protecting itself from damage. This usually indicates a communication error or a faulty part cutting off the system's flow. As multi-brand heating specialists, our technicians run full diagnostics to identify the exact component failure, clear the error codes, and install genuine replacement parts to get your automation back on track.
Unusual noises usually mean your system is working too hard due to mechanical issues or an internal restriction. We inspect your entire setup to quickly locate the source, clear the issue, and ensure smooth, quiet operation before it turns into a major breakdown.
This is a classic sign of solar degradation. Your old solar collectors are breaking down internally and flushing into the pool. We can assess if a localized repair is possible or if it's time to upgrade to a high-durability system.
As a Sunbather Authorised Dealer, we use genuine components engineered for tough Australian conditions — not generic parts that fail within a season.
We don’t just “parts swap.” Every job starts with system pressure tests and flow rate analysis to find the root cause, so the same fault doesn’t come back.
While based in Somerville, we provide rapid mobile service from Brighton and Bayside to the tip of the Mornington Peninsula and beyond.
