What does the SEER rating measure in relation to a heat pump?

The Seasonal Energy Efficiency Ratio (SEER) rating specifically measures the cooling efficiency of a heat pump over a typical cooling season. It is a ratio of the cooling output (measured in British thermal units, or BTUs) divided by the total electric energy input (measured in watt-hours) consumed during that same period. A higher SEER rating indicates a more efficient cooling system, meaning it provides more cooling output for each unit of energy consumed.

Understanding the SEER rating is vital for customers looking to optimize energy use and reduce electricity costs, especially in regions with significant cooling needs. It serves as an essential guide when evaluating the efficiency and operational costs of air conditioning systems, including heat pumps, that are used primarily for cooling.
