Start with safe basic checks
Coastal humidity and salt-laden air can accelerate corrosion on exposed metal and electrical contacts. Keep appliances dry and allow ventilation around heat-producing units.
Step 2
Clean AC filters and accessible outdoor-unit surroundings regularly, but leave chemical coil cleaning and electrical work to trained technicians.
Step 3
Use properly earthed outlets and suitable surge protection where recommended. Do not use loose adapters or undersized extension cords for high-load appliances.
When to book a technician
After long periods of non-use, inspect cables, plugs and signs of pest damage before powering an appliance.
Safety note
Disconnect power where the manufacturer instructs. Do not open sealed electrical or refrigerant systems without proper training.
