How Exactly Is Energy Efficiency Measured Anyway?


You probably already know that energy costs are on the rise in the US.
With reports showing that annual heating and cooling bills can reach over
$1000, it’s no surprise that homeowners are looking for a way to
reduce their monthly spending on their
air conditioning. Understanding that it’s tough to reduce energy bills if you don’t
truly understand how energy efficiency is measured, Del-Air strives to
educate home and business owners about this crucial factor.

The key to buying the most energy-efficient HVAC systems lies in understanding
the various efficiency ratings used in the industry. Here are the top
5 energy ratings you need to know about:

  • Energy Efficiency Ratio (EER): The EER is a measure of the cooling power of an air conditioning system
    per unit of power consumed. A higher EER corresponds with a more powerful system.
  • Seasonal Energy Efficiency Ratio (SEER): SEER gives the average efficiency for the whole season, so it is a more
    reliable efficiency rating for air conditioners than other metrics.
  • Energy Star: All Energy Star-rated HVAC equipment must undergo extensive testing to
    determine its performance level. If a system does not score a SEER of
    14.5 or higher on the test, it can’t bear the Energy Star label.
    Hence, buying Energy Star products is a great way to reduce your monthly
    utility costs while contributing to nationwide energy savings.
  • Heating Seasonal Factor Performance (HSFP): This rating measures the efficiency of the heating element of a heat pump.
    A higher HSPF rating corresponds with a more energy efficient system with
    the best pumps delivering an SFP rating of 3.5 to 5.
  • Minimum Efficiency Reporting Value (MERV): A rating for air filters in HVAC equipment, MERV refers to the size of
    the holes in the filter. MERV ratings range from 1 to 16 with the latter
    being the highest efficiency.
