Shutdown Your Evaporative Cooler for Winter!

Shutdown Your Evaporative Cooler for Winter!

Now that Adelaide is experiencing colder, wetter weather, it is time to give your evaporative air conditioner an end-of-season shutdown. Many homeowners forget about their cooling units once the heat fades, but a “set-and-forget” approach can lead to higher heating bills and nasty surprises when summer returns.

At Sharpe Trade Services, we follow manufacturer recommendations that your unit be professionally serviced at both the start and the finish of the season.

The Benefits of a Professional Winter Shutdown

Correctly preparing your system for the winter months offers several critical benefits for your home and your wallet:

1. Improve Your Home’s Heating Efficiency

An open evaporative cooler acts like a giant chimney on your roof. Without a proper shutdown and the installation of internal winter covers (if applicable), your expensive heater-warmed air escapes straight out through the vents. Closing the system keeps the warmth where it belongs—inside your living rooms.

2. Prevent Bacteria and Algae Growth

If water is left sitting in the reservoir over the winter, it becomes stagnant. This provides a perfect breeding ground for algae, slime, and bacteria. When you turn the unit on again in spring, these contaminants can be blown into your home. We drain and clean the reservoir to ensure it stays hygienic.

3. Increase System Longevity

Summer takes a toll on your system’s components. During a shutdown service, we check for wear and tear on the pump, motor, and pads. Identifying small issues now prevents them from turning into expensive breakdowns during the first summer heatwave.

4. Protect Against the Elements

Winter in Adelaide can be harsh. Ensuring the unit is securely covered and the water supply is isolated prevents frost damage to pipes and keeps debris like damp leaves from rotting your cooling pads.

“Energy audits from 2025 show that homes with unsealed evaporative cooling vents can lose up to 25% of their ducted heating efficiency through ‘thermal siphoning’ into the roof cavity.” — Australian Sustainable Housing Report 2026
