Understanding HVAC Ratings for Energy Efficiency

When searching for a new heating or cooling system for your home, you might see a list of energy efficiency ratings displayed on the units. These can help you determine how much each system would cost to purchase and operate. These include seasonal energy efficiency ratio (SEER), energy efficiency ratio (EER), and higher rated heating seasonal performance factor (HSPF). Birdwell Heating & Cooling discusses these ratings in detail.

Understanding HVAC Ratings for Energy Efficiency

SEER

SEER specifies the electrical input that’s necessary to run your cooling equipment compared with the amount it generates. A higher SEER rating means that you’ll get more production from your cooling equipment for the same amount of energy. To get these results, the SEER is tested based on an operating temperature of 82 degrees. Thanks to recent advancements, many cooling systems have improved their SEER ratings, so it’s a good idea to replace your old one with a newer, more efficient model.

EER

The EER is another way to measure the efficiency of your air conditioning system. It is calculated by testing the system at 95 degrees or higher while factoring in humidity removal. The EER is vital because it determines how well an air conditioning unit will perform under its maximum cooling load. As the expert on AC repair, we recommend considering both the SEER and EER ratings when selecting a new unit.

HSPF

Lastly, HSPF measures the efficiency of your HVAC system over a heating season. Similar to the SEER, it measures the efficiency of your system over one season. The ratio of heat that’s generated by the system to the electricity that it needs to operate determines a system’s HSPF rating. Energy-efficient heat pumps have a maximum HSPF rating of 10. You can use this rating to gauge how well your heating system will perform over time.
