Why Older Evaporative Coolers Need Regular TLC to Survive Summer
It’s a mistake many homeowners make: they only worry about their cooling systems when they start playing up. For evaporative cooling, being proactive is the difference between a breezy, affordable summer and a sweltering afternoon spent waiting for an emergency repair.
Older systems, in particular, require regular maintenance to set them up for summer and properly close them down for winter. This isn’t an expensive procedure, but the small outlay pays huge dividends by containing running costs and extending the life of your unit.
The Cost of Neglect
When an evaporative cooling system isn’t running properly, it often “sucks up” huge amounts of electricity. A malfunctioning unit forces the fan motor to work overtime to push air through clogged filters, putting a massive strain on crucial internal parts.
Recently, we were called to an Adelaide property where the owner reported their system just wasn’t “doing its job.” Our in-house technician discovered that while the unit was in reasonable condition for its age, it was suffering from two common issues:
- Dirty Filter Pads: Over years of service, pads accumulate dust and mineral deposits that block airflow.
- Faulty Water Inlet Valve: This crucial component was no longer delivering the correct amount of water to keep the pads moist.
Spotlight: The Water Inlet Valve
The water inlet valve is the gateway for your system’s cooling power. Since an evaporative cooler works by drawing hot outside air through water-saturated pads, if this valve fails, your system becomes nothing more than a giant, expensive fan.
Our trusted and experienced technicians specialize in detecting these specific failures. By replacing a single valve and cleaning the system, we can often bring an older unit back to its full performance specifications without the need for a total system replacement.

FAQ
The most common cause is a lack of water on the filter pads. This can be due to a faulty water inlet valve, a blocked pump, or a malfunctioning float valve. Without water, the “evaporation” process cannot occur.
If the cabinet and motor are in good condition, replacing minor parts like water valves or filter pads is a very cost-effective way to get several more years of life out of your system.
Depending on the water quality in your part of Adelaide, pads typically last between 5 and 10 years. If you notice a “musty” smell or see white mineral crusting on the pads, it’s time for a replacement.
A technician will drain the water reservoir, clean out any sediment, and turn off the water supply. This prevents stagnant water from breeding bacteria over the winter and protects your pipes from freezing or leaking.
