How does air conditioning work?
Modern split-system air conditioners use a refrigerant cycle to move heat out of your home in the summer — and pump heat back in during winter. Inverter-driven compressors mean they sip electricity, often delivering 4kW of cooling for every 1kW of energy used.
A quiet indoor head sits on your wall; the slim outdoor unit lives outside. Together they keep every room at the exact temperature you want — controlled by a remote, app or smart speaker.
