JB Quality Air Conditioning Service

I’ve just had a client ask me a question regarding the average running costs of a ducted evaporative air conditioner for a four bedroom home, so I thought I’d share the answer to the wider community too 😊

Here’s a realistic ball park guide to the average cost of running a ducted evaporative air conditioner in a typical 4 bedroom home in SA.

✅ Typical ducted evaporative system (whole house)
• About $0.14 to $0.35 per hour to run, depending on system size and electricity rate. 
• That’s roughly:
• 💰 $1.10–$2.80 for 8 hours per day
• 💰 $30–$85 per month if used most days
• 💰 $100–$250 for a whole summer (3 months)

These estimates assume electricity around 35–45c/kWh (typical Aussie rates).

Our local installer suggests:
• $50–$150 per summer for many Adelaide homes (much cheaper than refrigerated air conditioning ). 

⸻

⚡ Why evaporative is cheap to run
• Uses only fans and a water pump (no compressor).
• Uses roughly 1/10th the electricity of ducted refrigerated air conditioning. 

⸻

🏠 What affects YOUR actual cost

The cost for a 4 bedroom home depends on:
• Size of the unit (kW rating)
• How many hours per day you run it
• Electricity tariff (flat vs time of use)
• Insulation and house size
• Outdoor temperature & humidity
• Solar panels (can make it almost free during the day)

⸻

💡 Simple example (4 bedroom Adelaide home)

👉 Medium ducted evaporative system (750 W)
👉 Electricity 40c/kWh
👉 Run 8 hours per hot day

Cost per day: about $1.70–$2.20

🔥 Comparison (for perspective)
• Evaporative air conditioning: $100–$250 per summer
• Ducted refrigerated air conditioning: often $500–$1,500+ per summer.

(There’s a huge difference in running costs).
