What are SEER and EER?
What is SEER?
SEER- Seasonal Energy Efficiency Ratio
This measures how efficiently an HVAC system will operate over an entire cooling season, as opposed to a single outdoor temperature. As with EER, a higher SEER reflects a more efficient cooling system. SEER is calculated based on the total amount of cooling (in BTU’s) the system will provide over the entire season divided by the total number of watt-hours it will consume. Unfortunately, this test is done in a controlled environment and may not reflect the temperatures in your area. The test uses an outdoor temperature of 82 degrees F and an indoor temperature of 80 degrees F with 50% humidity.
What is EER?
EER- Energy Efficiency Ratio
EER is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level( 95 degrees F). A higher EER means the system is more efficient. The formula for calculating EER is BTU’s/hr of cooling at 95 degrees divided by watts used at 95 degrees. When this test is performed, an indoor temperature of 80 degrees with 50% humidity is used. Having a 15 degree difference at a higher outdoor temperature is much more realistic.
