The Seasonal Energy Efficiency Ratio (SEER) is a metric that measures how efficient your heating and cooling system is. Specifically, it quantifies how much cooling output you receive for each dollar spent on electricity, providing a clear picture of the unit’s performance. A higher SEER rating signifies greater energy efficiency, meaning the system uses less energy to produce the same amount of cooling. Typically, air conditioning units and heat pumps have a SEER rating ranging from 13 to 17, with higher ratings indicating more advanced technology and better energy savings over time. Investing in a unit with a higher SEER rating can lead to lower utility bills and a reduced environmental impact.
