Every day there are more advertisements about energy saving products. The government has created an Energy Star rating which means that it approved to their standards on cutting down energy consumption. In HVAC equipment this translates to a SEER rating. SEER stands for Seasonal Energy Efficiency Ratio. It’s the industry standard for rating the cooling efficiency of air conditioners and heat pumps. Much like miles-per-gallon for a car, it’s an easy way to compare efficiencies of different products — the higher the SEER, the more efficient the unit.
