Our Frequently Asked Questions
We recommend servicing your air conditioner at least once a year, ideally before summer or winter. Melbourne’s fluctuating climate puts extra strain on systems, and regular servicing helps prevent breakdowns, improves efficiency, and extends the lifespan of your unit.
The correct size depends on several factors including room size, ceiling height, insulation, window placement, and how many people use the space. An undersized unit won’t cool effectively, while an oversized unit can waste energy. A professional on-site assessment ensures the system is correctly sized for Melbourne conditions.
Both systems work well in Melbourne.
- Split systems are ideal for cooling or heating individual rooms and are more cost-effective upfront.
- Ducted air conditioning is best for whole-home comfort, offering zoning and a clean, discreet finish.
The best option depends on your home layout, usage, and budget.
Yes, evaporative cooling works well in Melbourne’s generally dry summer conditions, especially in open-plan homes. However, performance can reduce on very humid days. A professional assessment will determine whether evaporative or refrigerated air conditioning is the best choice for your home.
This can be caused by issues such as low refrigerant levels, dirty filters, thermostat problems, or electrical faults. If your system is blowing warm air when it should be cooling, it’s best to have it inspected by a licensed technician to prevent further damage.
- Split system installations typically take 3–6 hours
- Ducted air conditioning installations usually take 1–3 days, depending on the size of the property and system complexity
We always aim to minimise disruption to your home or business.
Water leaks are often caused by blocked drains, dirty filters, frozen coils, or incorrect installation. While minor blockages can sometimes be fixed quickly, ongoing leaks should be inspected by a professional to avoid water damage.
Modern air conditioners are designed to be highly energy-efficient. Regular servicing, correct system sizing, zoning, and smart thermostat use can keep running costs low. An older or poorly maintained system is more likely to increase energy bills.
Yes. Air conditioning systems filter dust, allergens, and airborne particles. Regular servicing and clean filters are essential to maintain good air quality—especially for families with allergies or asthma.
For energy efficiency and comfort:
- Summer: 23–25°C
- Winter: 19–21°C
These settings provide comfort without overworking your system or increasing energy costs.
With proper installation and regular maintenance, most air conditioning systems last 10–15 years. Factors such as usage, servicing frequency, and system quality all affect lifespan.
In most cases, split systems and ducted air conditioning do not require council approval. However, installations in apartments, heritage-listed buildings, or body corporate-managed properties may require approval. We can guide you through the process if needed.
If your system is over 10–12 years old, frequently breaking down, or costly to run, replacement is often more economical than ongoing repairs. Our technicians provide honest advice to help you decide.

“We recently had our new ducted air conditioning system installed and couldn’t be happier with the service. The boys from King & Sons arrived on time, explained everything clearly, completed the installation to a very high standard, and left the house spotless. It’s refreshing to deal with a company that genuinely cares about customer service. Highly recommend to anyone in Melbourne looking for reliable air conditioning specialists.”
