Understanding Common HVAC and Water Heating Unit Ratings
Use this short guide to understand common HVAC and water heating unit ratings such as SEER2, HSPF2, and UEF, how they impact energy efficiency , and what they mean for your home.
Learn about HVAC efficiency ratings in this comprehensive guide. Discover how to choose energy -efficient systems to save on costs and improve home comfort.
Understanding HVAC Efficiency Ratings
Discover what EER, HSPF, and SEER HVAC efficiency ratings mean and how they're calculated to get the best energy savings with HVACDirect.com.
Under the updated guidelines, the ratings have become SEER2, EER2, and HSPF2. The goal of the new standards is to lower energy consumption by increasing energy efficiency . A bonus for homeowners: You can realize energy cost savings by buying a more efficient HVAC system.
Understanding HVAC Energy Efficiency Ratings
An easy way to conserve energy is to make sure your heating or cooling system is as energy -efficient as possible. You can determine a heating or cooling system's efficiency level by reviewing its bright yellow EnergyGuide label, which includes an output-to- energy (electricity or gas) ratio. Not sure how to interpret these labels? In this month's blog, we explain how to read EnergyGuide ...
Learn about SEER, HSPF, and AFUE ratings to understand HVAC energy efficiency and make informed decisions when choosing a new HVAC system.
HVAC Efficiency Ratings Explained
See how SEER2, AFUE and HSPF2 affect HVAC prices and energy bills, including 2026 minimums, current utility rebates and the 25C cutoff.
Four standardized rating systems — SEER, EER, HSPF, and AFUE — form the regulatory and commercial language for measuring how efficiently HVAC equipment converts energy input into useful heating or cooling output. The U.S. Department of Energy mandates minimum values for each metric under 10 CFR Part 430, and those minimums were revised upward for most equipment categories effective January ...
All HVAC Efficiency Ratings Compared (SEER2, EER2, HSPF2, COP, AFUE)
The HVAC industry uses at least 10 different efficiency ratings , each measuring something slightly different. SEER2 measures seasonal cooling efficiency , EER2 measures peak-load cooling efficiency , HSPF2 measures seasonal heating efficiency for heat pumps, COP is the universal efficiency ratio, and AFUE measures furnace fuel-to-heat conversion.
Buying a New System If your heating or cooling system is over 15 years old, you can save on electric bills and improve your home's energy efficiency by investing in new equipment. The system you choose will depend on the size of your house, amount of insulation, heating and cooling usage, and local climate. Look for systems with the ENERGY STAR® label, which meet performance requirements ...
