Understanding ENERGY STAR® Ratings

When shopping for new heating or cooling equipment, you’ll likely come across the ENERGY STAR® label. But what does it mean, and how does it impact your decision? ENERGY STAR® ratings are a government-backed standard for energy efficiency, designed to help homeowners identify systems that perform better and cost less to operate. At Modern Heating & Plumbing Co. in Gurnee, IL, we help homeowners understand these ratings and choose equipment that saves money while maintaining comfort.


Choosing ENERGY STAR®-rated equipment isn’t just about reducing energy use—it’s also about long-term savings, improved performance, and a smaller environmental footprint. Whether you're replacing an aging furnace or upgrading your air conditioner, understanding how ENERGY STAR® works can guide you toward a smarter investment.

About Us

What Does the ENERGY STAR® Label Mean?

The ENERGY STAR® label signifies that a product meets or exceeds strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). Only products that meet these standards in both performance and energy use are eligible for certification. This label makes it easy for homeowners to compare equipment and find options that offer real savings.

  • Indicates high energy efficiency and performance
  • Set by the U.S. Environmental Protection Agency (EPA)
  • Helps reduce energy bills and carbon footprint
  • Makes it easier to identify efficient equipment

Benefits of ENERGY STAR®-Certified Equipment

ENERGY STAR®-certified systems use less energy to heat or cool your home, which translates into lower monthly utility bills. In addition to saving money, these systems typically offer quieter operation, better temperature control, and longer system lifespans due to reduced wear and tear.

  • Reduces annual heating and cooling costs
  • Improves home comfort with more consistent temperatures
  • Systems are typically more durable and quieter
  • Contributes to a cleaner environment through lower emissions

SEER, EER, and AFUE Explained

ENERGY STAR® ratings are based on performance metrics like SEER (Seasonal Energy Efficiency Ratio), EER (Energy Efficiency Ratio), and AFUE (Annual Fuel Utilization Efficiency). A higher SEER or EER means better cooling efficiency, while a higher AFUE indicates a more efficient furnace. Understanding these numbers can help you compare systems and select the right fit for your needs.

  • SEER, EER, and AFUE ExplainedSEER measures cooling efficiency over a season
  • EER measures efficiency at a fixed temperature
  • AFUE measures furnace efficiency as a percentage
  • Higher numbers mean better performance and energy savings

Are ENERGY STAR® Systems Worth the Investment?

Though ENERGY STAR® systems can cost more upfront, the long-term savings on energy bills often make up for the difference. Additionally, many utility companies offer rebates or incentives for installing high-efficiency systems. When properly installed and maintained, these systems provide lasting comfort and lower operational costs.

  • Higher upfront cost balanced by lower operating expenses
  • Eligible for energy rebates and tax incentives
  • Ideal for homeowners seeking long-term value
