Living near Kohimarama Beach is special – but the salt air, humidity, and coastal conditions require heat pumps that can handle the environment. We specialise in coastal installations that last.
Standard heat pump installations don't account for coastal conditions. Kohimarama's salty air, high humidity, and intense afternoon sun require specific equipment choices and careful positioning.
Kohimarama's proximity to the beach means salt-laden air that can corrode poorly-specified equipment. We recommend and install coastal-rated outdoor units with anti-corrosion coatings designed for beachside environments.
Coastal Auckland humidity can make homes feel clammy even when temperatures are mild. Modern heat pumps with dehumidification modes are ideal for Kohimarama – keeping your home comfortable without overcooling.
Many Kohimarama properties face the beach and cop intense afternoon sun. We correctly size systems for the actual heat load, not just floor area – ensuring effective cooling when you need it most.
The onshore breeze is great for sailing, but outdoor units need careful positioning. We place condensers to work with prevailing winds, not against them, improving efficiency and reducing running costs.
Not all heat pumps are created equal when it comes to coastal durability. "Coastal rated" or "blue fin" units feature treated condenser coils and enhanced weatherproofing specifically designed for salt-air environments.
For Kohimarama properties, especially those within a few hundred metres of the beach, this specification can mean the difference between a 5-year lifespan and a 15-year lifespan for your outdoor unit.

We'll assess your property and recommend the right system for your needs.

All coastal areas in Eastern Auckland benefit from our specialist knowledge of salt-air conditions and appropriate equipment selection.
Common questions from Kohimarama homeowners about heat pumps in coastal environments.
Yes and no. The heat pump technology is the same, but the outdoor unit specification matters. We recommend 'coastal rated' or 'blue fin' condenser units for properties within 500m of the waterfront. These have enhanced corrosion protection that significantly extends the unit's lifespan in salt-air environments. The cost difference is modest compared to the longevity benefit.
Kohimarama's coastal humidity means your heat pump works double duty – managing temperature and moisture. We recommend units with dedicated dehumidification modes that remove moisture without overcooling your home. This is particularly important in older Kohimarama homes that may have less insulation and more air exchange with outside.
Positioning is crucial in coastal Kohimarama. We consider prevailing wind direction, salt spray exposure, and aesthetics. Often, placing units on the less exposed side of the building (away from direct sea views) extends their life while maintaining efficiency. Ground-level installations on concrete pads work well when sheltered by fencing or landscaping.
For Kohimarama homes, expect $2,200-$4,000 for a single coastal-rated heat pump installed, depending on size and complexity. Multi-room systems range from $7,000-$15,000+. We always quote coastal-rated units for beachside properties – the small premium is worth it for durability. Free quotes available.
Yes, we frequently repair salt-damaged units in Kohimarama. Common issues include corroded condenser fins, degraded electrical connections, and compressor stress from restricted airflow. Sometimes cleaning and protective treatments can extend life; other times replacement is more economical. We'll give you honest advice on the best option.
Salt air travels further than you'd think – we generally recommend coastal-rated units for any property within 1km of the beach. If you're further back in Kohimarama towards St Johns or St Heliers, standard units may be fine. We'll assess your specific location during the quote visit.
A heat pump is a significant investment. In coastal Kohimarama, getting the right equipment and installation makes all the difference to longevity and performance. Let us assess your property and recommend the best approach.
