Vincentia Coastal Home – Corrosion-Resistant Split System Air Conditioning Upgrade
Introduction
Location: Vincentia (Jervis Bay)
Service: Split System Upgrade
Client Type: Coastal Residential Home
Outcome: Longer equipment lifespan, quieter operation, 22% lower running costs

A coastal homeowner in Vincentia was dealing with a failing split system badly affected by salt corrosion. The unit struggled in summer, ran loudly and required frequent repairs. They needed a new, reliable system designed specifically for coastal conditions with better efficiency and quieter operation.
Summary of Results
- Coastal-rated Daikin split system installed
- Corrosion resistance significantly improved system lifespan
- 22% reduction in running costs
- Much quieter operation in the living area

Client Background
The homeowner lived less than 300m from the coastline — a high-corrosion zone. Their existing AC suffered from:
- Rusted coils
- Loud operation
- Poor cooling performance
- High summer electricity bills

They needed a long-term coastal-ready solution.
The Challenge
- Severe salt-air corrosion
- High humidity and summer load
- Inefficient older unit consuming too much power
- Poor airflow to dining and lounge zones
Strategy & Actions Taken
System Selection
A Daikin coastal-rated split system with anti-corrosion coating was chosen for longevity.
Positioning & Installation
- Outdoor unit relocated to a protected southern wall
- Vibration pads added to reduce noise
- Indoor unit placed to maximise cross-flow across open-plan areas
Airflow Optimization
Redirected louvres and adjusted install height for maximum room coverage.
