Evaporative coolers are a popular choice in Melbourne for their energy efficiency and ability to keep homes and businesses cool during hot months. But like any HVAC system, they require regular maintenance to perform at their best. So how often should your evaporative cooler be serviced and why is it so important?

At Hilux Cleaning Services, we often get this question from customers looking to extend the life of their units and avoid costly repairs. Let’s break it down.

Why Servicing Your Evaporative Cooler Matters

Evaporative coolers pull in outside air, filter and cool it through water-saturated pads, and then circulate it into your indoor space. Over time, dust, debris, algae, and minerals from hard water can build up in the system.

Here’s why regular servicing is essential:

  • Improves cooling efficiency
  • Reduces electricity usage
  • Prevents health issues caused by mold and bacteria
  • Extends the unit’s lifespan
  • Avoids unexpected breakdowns during peak seasons

How Often Should an Evaporative Cooler Be Serviced?

➤ At Least Once a Year (Minimum)

For residential properties in Melbourne, we recommend having your evaporative cooler serviced at least once a year, ideally before summer begins. This ensures your system is clean, safe, and ready to cool effectively.

➤ Twice a Year (For Best Results)

In areas with hard water or frequent dust (like near construction zones or open land), a mid-season and post-season check can be beneficial. This keeps mineral buildup and dust at bay.

➤ More Frequently for Commercial Spaces

For commercial or high-usage environments like gyms, factories, or warehouses, quarterly servicing is ideal to maintain air quality and system performance.

DIY Maintenance Tips Between Services

While professional servicing is essential, here are a few things you can do to keep your cooler in shape:

  • Check water levels regularly
  • Clean the filter pads occasionally
  • Inspect the vents and grilles for blockages
  • Run the fan only mode occasionally to dry out pads
  • Turn the system off during winter months

Still, nothing replaces a deep professional clean for safety and performance.
