Power prices bite harder here
Adelaide pays some of the highest electricity rates in the country, so the efficiency gap between two quoted units is worth more here than anywhere else. Compare the zoned energy label, not the sticker.
Built for the heatwave
Adelaide heat arrives in multi-day 40°C+ blocks. An undersized unit fails on exactly the days you bought it for, size for the heatwave, not the average.
Villas and high ceilings
Solid-brick villas and cottages with 3m+ ceilings need more capacity than the floor area suggests, and wall choice matters in double brick. Flag the ceiling height when you get quotes.
Check REPS before you sign
SA’s retailer energy scheme sometimes discounts high-efficiency cooling, depending on your retailer’s current offers. Thirty seconds to ask, occasionally a few hundred dollars back.
