How Air Conditioning Electricity Costs Vary by Energy Efficiency Level
Ideally (under the same conditions), a Level 1 energy-efficiency air conditioner costs 100 RMB in electricity, while Level 2 requires 110 RMB, Level 3 requires 125 RMB, Level 4 requires 140 RMB, and Level 5 requires 150 RMB.
So buying a genuine Level 1 energy-efficiency air conditioner is fundamentally a money-saving move (don’t buy from unofficial channels — make sure you get an invoice and official inspection/installation). Fake ones are common now because refurbished/assembled units are too easy to produce).
I highly recommend Haleon’s (华凌) Level 1 energy-efficiency models for their best price-to-performance ratio. On JD.com, you can add about 150 RMB extra for an 8-year free replacement service, so you can use it with peace of mind.JD.com official Haleon store (Level 1 energy-efficiency 1.5HP, lowest price around 1599 RMB, Midea’s sub-brand)
