Living by the coast and looking after your heat pump

Living near the beach is great. The salt air can be a bit hard on your heat pump, though.

The outdoor unit sits outside all year, catching whatever the weather throws at it. Around places like New Brighton, Sumner and Southshore, that can include plenty of salt.

Why salt matters

Salt and moisture can speed up rust and other damage to metal. You might see marks on the cover, but there can also be damage further inside.

That means a heat pump can still be working while parts are starting to deteriorate. Looking fine from the driveway does not always tell the whole story.

A few things you can check

Have a look for rust, peeling surfaces or leaves building up around the bottom. Keep plants and stored gear clear so air can move freely.

Ask us how to clean your particular model. Some can be gently rinsed in certain areas, but a water blaster can cause damage. Avoid spraying water into electrical parts.

What about a protective coating

A suitable coating adds a protective layer to help slow corrosion. We use Action Corrosion products where they suit the unit, with the right preparation first.

It may help the heat pump last longer, but it cannot fix metal that is already badly damaged. We check the condition before recommending treatment.

How often does it need attention

A unit facing the sea may need more care than one tucked away inland. How much you use it and the maker’s care instructions matter too.

If you are unsure, send us a photo and tell us your suburb. We can help you work out whether it needs a closer look.
