Evaporative Cooling Repairs Melbourne

It’s 38 degrees in Melbourne and your evaporative cooler has decided not to work. The fan is running but there’s no cold air, or nothing happens when you switch it on, or it makes a noise it didn’t used to make. It was fine last season. Now it isn’t.

Luno Electrical diagnoses and repairs evaporative cooling systems across inner Melbourne. We know the most common failure modes — pump failures, motor capacitor failures, blocked water distribution systems, failed wall controllers — and we carry the parts most commonly needed on the truck.

We give you an honest assessment of whether repair makes sense or whether the unit has reached end-of-life and replacement is the better investment. We don’t repair things that shouldn’t be repaired just to generate a job.

How It Works

Call us and describe what the system is doing — we’ll advise on likely causes and whether it’s worth an inspection.
We inspect the system, diagnose the fault and provide a fixed-price repair quote before touching anything.
We complete the repair, test the system across all settings, and clean up before we leave.

Assessment for repair vs replacement

An evaporative cooler that isn’t working isn’t just uncomfortable — Melbourne summers can be genuinely dangerous for elderly residents and young children without adequate cooling. A system that appears to be working but is running without water reaching the pads is just moving hot air.

A unit that isn’t serviced regularly accumulates mineral scale and algae that degrade efficiency, damage components, and in some cases create air quality issues. Regular servicing costs far less than replacement.

A repaired and serviced evaporative cooler running at full capacity can drop a room’s temperature by 8–12 degrees on a Melbourne summer day — at a fraction of the running cost of a reverse-cycle system. The pump is delivering water to fresh pads, the motor is running smoothly, and the wall controller works on every setting.

Call Luno Electrical on (03) 9982 9737 before the next heatwave. We diagnose and repair evaporative cooling systems across inner Melbourne, usually within 1–2 business days.

Commercial Evaporative Cooling

Evaporative cooling systems are common in older commercial and light-industrial buildings across Melbourne’s inner west and north. We service and repair commercial evaporative systems alongside our regular commercial electrical work, and can co-ordinate repairs around your operating hours.

Frequently Asked Questions

Why is my evaporative cooler running but not cooling?

The most common cause is a failed water pump — the fan is working but the pads are dry, so you're moving hot air without any cooling effect. Other causes include clogged or deteriorated pads, a failed water distribution header, or a thermostat set incorrectly. We can usually diagnose this on the first visit.

How much does evaporative cooler repair cost?

Minor repairs — pump replacement, capacitor, wall controller — typically cost $150–$350 including parts and labour. More significant component failures cost more. We provide a fixed-price quote before starting any work so you can decide whether to proceed.

How often should an evaporative cooler be serviced?

Annually — at the start of the cooling season (October/November in Melbourne) and a winterisation service at the end (March/April). Annual servicing replaces the pads, flushes the distribution system, and checks the pump and motor before the season starts — avoiding emergency repairs in the middle of a heatwave.

Whatever the job

From a single power point to a full rewire — one team for the lot.

What our customers say

Andrew and the team installed a Tesla wall charger at my home. They did an outstanding job and went over and above to make sure everything was done professionally and worked properly. Before finding Luno I spoke to many electricians and they often hadn’t done an electric car home charger installation before and didn’t seem to know what was involved. Andrew and the team at Luno quickly put me at ease because it was clear they knew how to install electric car charging. Would highly recommend.

Andrew and Alex were very professional and friendly, they took measures to not leave mess and tidied up after themselves. They were thorough in asking if we wanted switches changed etc to look the best. We love our new fans and bathroom heating light. Thank you
