Summer is our busiest time of year.
It's when all the other chillers on the market start to fall to pieces.
Pool temps rise to double digits in the morning and keep climbing.
Support lines go unanswered.
The one repair tech per state gets buried.
That's when people start calling us.
But why is summer so much harder on chillers than winter?
Your chiller removes heat from the water and pushes it into the surrounding air.
When that air is already hot, the whole process becomes much less efficient.
Think of it like opening your car windows to cool down.
On a 15°C day, the cool breeze drops your temperature fast.
On a 35°C day, that air barely helps at all.
Chillers work the same way - they have to fight so much harder to get the same result.
And they lose efficiency at a scary rate once ambient temp gets above 20°C.
Some data suggests 1% loss for every degree above 20.
But based on our testing, most chillers lose over 50% of their rated capacity when it creeps toward 30°C.
On a 35°C day, they're doing next to nothing except racking up your electricity bill.
Easy way to think about it: just like it's easy to get hot in a sauna, it's easy to get cold outside in winter.
But try getting cold in the sauna - that's what your chiller is attempting on a 35°C day.
Most equipment on the market was never designed for Australian conditions.
If you want help understanding whether yours was, we're happy to take a look.
