Frequently Asked Questions

Daikin parts are sourced from their global manufacturing network, including specialised facilities in Japan, Thailand, and Australia.

Look for the data plate on the side of your outdoor unit or the sticker on the underside of your indoor unit. This number is critical for finding compatible Daikin PCBs.

Yes, Daikin leads the industry in using R-32 refrigerant, which has a significantly lower global warming potential than older refrigerants.

This might surprise you, but the ‘size’ of an air conditioner has nothing to do with the unit’s physical dimensions. Size actually refers a unit’s ability to produce cool and/or warm air and is usually measured in kilowatts (kW). To understand the right size air conditioner you need you need to know the size of the room including the ceiling height.

The following formula is a guide only. You should always obtain a visual inspection by a qualified air conditioning installer to confirm the correct air conditioning size and air conditioning type for your needs.

1. Length of the Room x Width of the Room x Height of Ceiling = Area

2. Area x 150 = Cooling Watts

3. Cooling Watts / 1000 = Approximate Air Conditioning Unit Size (kW) 5 meters x 4 meters x 2.4 meters = 48 48 x 150 = 7200 7200 / 1000 = 7.2 For this example, this room would require a 7.2kW system

The cost of installing a Daikin air conditioning system varies based on the complexity of the job. Generally, you can expect to pay a qualified technician approximately $200 per hour (plus GST), but the total investment is determined by three main factors:

1. Installation Type & Complexity

2. Replacement vs. New Install: Replacing an existing unit is often more cost-effective. Technicians can frequently reuse existing brackets, pipework, or ducting, significantly reducing labour and material costs.

3. Unit Location: Ground-floor installations are the most affordable. If the outdoor unit requires wall brackets on a second story or roof mounting, costs increase due to the need for specialised height safety equipment.

4. Estimated Labour Timeframes

5. Installation times vary by system type. As a guide, expect the following:

• Wall Split System: ~4 hours (1 technician).

• Multi-Split System: ~8 hours (1-2 technicians).

• Ducted System: 1–3 days (2-3 technicians).

1. The "Budget Rule of Thumb" (kW Method)

2. If you are looking for a quick estimate for the combined cost of the Daikin unit plus installation, use the General kW Method:

• Wall Split / Multi-Head Systems: Budget approximately $500 per kW (e.g., a 5kW system ≈ $2,500).

• Ducted Systems: Budget approximately $1,000 per kW (e.g., a 12kW system ≈ $12,000).

Prices are estimates only. We recommend getting a site inspection from a licensed Daikin installer for an accurate quote.

A high-quality Daikin air conditioning unit typically has an operational lifespan of 10 to 15 years. However, with meticulous maintenance and the use of genuine components, many Australian homeowners see their systems perform reliably well beyond the 15-year mark.

To maximise the life of your investment, follow this essential maintenance guide:

1. Regular Filter Maintenance

2. Clean: Every 3–6 months to ensure optimal airflow and prevent the indoor motor from overworking.

3. Replace: Every 1–2 years. Using fresh Daikin filters ensures the air stays clean and the internal coils remain free of dust buildup.

4. Annual Professional Servicing

Schedule a yearly check-up with a qualified air conditioning technician. They can identify minor issues—like a failing capacitor or a worn fan motor—before they turn into expensive system failures.

1. Protect the Outdoor Unit

2. Clear Debris: Keep the area around your outdoor unit free from leaves, grass clippings, and cobwebs to maintain heat exchange efficiency.

3. Remove Covers: Always ensure any protective weather covers are removed before operation to prevent the Main PCB from overheating.

4. Smart Operation Habits

5. Temperature Settings: Aim for a consistent range between 22°C and 26°C. Forcing the unit to run at extreme temperatures (like 16°C) puts unnecessary strain on the inverter compressor.

6. Auto Fan Mode: Use the "Auto Fan" feature. This allows the system to regulate its own workload, reducing wear and tear on the internal components.
