SEER Rating (Seasonal Energy Efficiency Ratio)

Definition

A SEER rating measures the cooling efficiency of air conditioners and heat pumps over a typical cooling season. Higher SEER numbers mean greater efficiency: a SEER 16 unit costs roughly 20% less to operate than a SEER 13 unit. Federal minimums are SEER 14-15 depending on region, while premium units reach SEER 25+.

Understanding SEER Rating (Seasonal Energy Efficiency Ratio)

SEER is calculated by dividing the total cooling output (in BTUs) over a season by the total electrical energy input (in watt-hours). Homeowners should know their SEER rating because it directly affects utility bills and because aging equipment loses efficiency over time. Shipshape tracks HVAC efficiency trends and alerts homeowners when performance degrades, often catching issues months before a full system failure.
