Is Your System Energy-efficient? 

If you want to make sure the system you are considering for your commercial property is energy-efficient, look for higher percentages in the following: 


  • Annual fuel utilization efficiency (AFUE)

  • Heating seasonal performance factor (HSPF)

  • Seasonal energy efficiency rating (SEER)

  • Energy Star® rating

What Is an Energy Star® Certification?

An Energy Star® rating denotes that the product is high in energy efficiency. Having a certified product means great energy savings. For example: 


  • If your equipment’s SEER rating is at 52% then you would end up paying only $48 a month on heating and cooling as opposed to $100.

  • At an HSPF rating of 29%, your system would save you $29 out of a potential $100 on heating and cooling expenses for a month.

  • At an HSPF rating of 23%, your system would save you $23 out of a potential $100 a month on heating and cooling costs.
