Fault codes & resets, explained properly
Before you book anything, try the safe checks. Half the calls we get are a filter, a closed water tap or a breaker — and we'd rather tell you that for free.
Gas ducted heating
Brivis ducted heater not working
Brivis units are all over the Bellarine and Geelong, and most no-heat calls come down to one of five things: a tripped lockout, a blocked return-air filter, a failed ignition sequence, a faulty controller or a gas supply issue. Some of that you can safely check yourself in five minutes.

Braemar gas heater fault codes
Braemar ducted heaters signal faults through the wall controller or a flashing status light on the unit itself. Knowing what kind of fault you're looking at tells you whether it's a filter clean or a board replacement.

Bonaire evaporative cooling troubleshooting
Evaporative coolers only work when water, airflow and pads are all doing their job. Nine out of ten "blowing warm" calls we get on the Bellarine are a water or pad problem, not a dead motor.

Vulcan and Rinnai gas heater troubleshooting
Vulcan and Rinnai gas heaters are common in older Bellarine homes, and many are well past the age where an annual service and carbon monoxide test should be optional.

Replacing gas ducted heating with electric
Gas prices have changed the maths, and it's now the question we're asked most: when a ducted heater dies, do you replace it with gas or go electric reverse cycle? Here's the honest answer for Bellarine and Geelong homes, with real numbers rather than marketing.

Evaporative cooling vs split system
On the Bellarine this decision comes down to humidity and salt, not brochures. Evaporative cooling is cheap to run and brilliant on a hot dry northerly. A split system works on every hot day, including the muggy ones. Here's how to choose.

Ducted heating vent & duct replacement
Most "my heater isn't working properly" calls in Geelong and on the Bellarine turn out to be ductwork. Here's how to tell, what repair and replacement cost, and when it's worth doing rather than replacing the unit.

What size split system do I need?
Get the size wrong and you either run flat out and never get there, or you short-cycle, waste power and never dehumidify properly. Here's the sizing we work to, and the things that shift it up or down in Bellarine and Geelong homes.
