🤔 What is SEER?

SEER (Seasonal Energy Efficiency Ratio) measures the efficiency of air conditioners and heat pumps during the cooling season. It’s calculated by dividing the cooling output by the electric energy input.
✅ A higher SEER value = greater efficiency, lower energy bills, and reduced environmental impact.
Modern ductless mini splits often exceed minimum standards, delivering advanced energy savings.
