❄️ The 2026 Guide to Lowering Gas Bills in Berwick, Hallam & Endeavour Hills

If you’re a homeowner in the City of Casey, you’ve likely noticed your winter gas bills creeping up. With the weather jumping from 34°C heatwaves to frosty mornings, it’s easy to get “bill shock.”

Most people think they need a new heater to save money. As a local specialist who has spent years in the roofs of Hallam and Berwick homes, I can tell you: Maintenance beats replacement every time.


🛠️ Why Your Current Heater is “Wasting” Money

Many “budget” service companies just brush off the dust. At Mr. Frosty, we look at the technical calibration that actually lowers your MJ (megajoule) usage.

FeatureThe Problem (Higher Bills)The Mr. Frosty Fix (Lower Bills)
Burner PressurePressure too high = Wasted gas.Calibrated to factory specs.
Duct IntegrityLeaks = Heating your roof cavity.100% seal check on all joins.
Return Air FilterClogged = Motor works 2x harder.Deep clean for maximum airflow.
ThermostatSet at 23°C+ = 30% more usage.Calibration & 19-20°C advice.

1. The 1°C Thermostat Hack

This is the single most effective way to save money. Most homes in the South East are kept much warmer than they actually need to be.

  • The Rule: Aim for 19°C – 20°C.

  • The Math: Every degree you drop your thermostat reduces gas usage by up to 10%.

  • Pro Tip: If you have a Brivis or Braemar controller, set it to 16°C overnight.

2. Thick Curtains: Your Secret Insulation

In Endeavour Hills, where we get those biting morning frosts, your windows act like massive ice blocks.

  • The Move: Close thick, light-blocking curtains as soon as the sun goes down.

  • Why it works: It creates a pocket of still air that prevents heat from escaping through the glass.


💰 Pro Move: Get $200 Back from the City of Casey

Did you know the City of Casey offers a Home Energy Efficiency Rebate? Residents can claim up to $200 per household for products that help “seal” your home.

  • What’s covered: Draught stoppers, gap sealants, and thermal blinds.

  • Mr. Frosty Tip: Borrow an “Energy Audit Kit” from the Bunjil Place Library to find your leaks before we arrive!


⚠️ Safety First: The 2-Year Rule

Beyond the savings, safety is paramount. Energy Safe Victoria recommends a professional service and Carbon Monoxide (CO) test every two years. A cracked heat exchanger is a silent danger that only a qualified technician can detect.

Whether you’re in Narre Warren, Hallam, or Berwick Springs, don’t wait for the first 10-degree morning to find out your heater is inefficient (or unsafe).
