What you'll notice
White or powdery deposits and crumbling aluminium fins on the outdoor coil, with cooling performance that has declined steadily over a few years.
Why it happens
Salt-laden air settling on the coil and corroding the aluminium fins and their bond to the copper tubing. Units within a few hundred metres of the sea are most affected, and units never rinsed are worst.
How we fix it
We assess how much fin surface remains viable and whether the coil can be cleaned and treated or has to be replaced. Where the unit is being replaced we specify a coated-coil model and site it out of direct salt spray.
Still not working?
If the checks above haven't restored your outdoor condenser unit, this usually needs a technician. Our Aircon Installation service covers exactly this fault — from R2 000, quoted upfront.
