Reading the SEER Chart
Higher SEER Ratings:
Systems with higher SEER ratings are more efficient. For instance, a system with a SEER rating of 18 uses less energy to produce the same amount of cooling as a system with a SEER rating of 14.
Lower SEER Ratings:
Older or less efficient models may have lower SEER ratings. While these systems may have a lower upfront cost, they typically result in higher energy bills over time.
SEER vs SEER2:
SEER2 ratings include updated testing standards, including static pressure, which provides a more accurate representation of real-world efficiency. The advantage of SEER2 is that it reflects how effectively an air conditioning system maintains efficiency under less-than-peak conditions. Since air conditioners typically operate at 50-80% of their maximum capacity during hot days, SEER2 provides a more accurate assessment of energy savings during typical usage.

What is AFUE for HVAC?
Annual Fuel Utilization Efficiency (AFUE) is a critical metric used to evaluate the efficiency of heating systems, such as furnaces and boilers. It measures how effectively a heating system converts fuel into usable heat over the course of a year. Expressed as a percentage, AFUE reflects the proportion of fuel energy that is transformed into heat, with the remainder lost during the process. For instance, a system with an AFUE of 90% means that 90% of the energy from the fuel is used for heating, while the remaining 10% is lost. Understanding AFUE is essential for businesses looking to optimize their heating systems, as higher AFUE ratings indicate greater efficiency, potentially leading to significant cost savings on fuel and improved energy performance.
How to Calculate AFUE
Understand the Formula:
AFUE measures how efficiently a furnace or boiler converts fuel into heat over a year. It is expressed as a percentage of the total fuel energy used that is converted into heat. The formula is:
Total Heat Output (BTUs): The amount of heat delivered by the system.
Total Fuel Input (BTUs): The amount of fuel energy consumed by the system.
Determine the Heat Output:
This is the total amount of heat produced by the heating system over a year. It is usually measured in British Thermal Units (BTUs). For instance, if a furnace outputs 100,000 BTUs of heat annually, this is the figure used for the heat output.
Measure Fuel Consumption:
Calculate the total amount of fuel consumed over the year, also measured in BTUs. If a furnace uses 120,000 BTUs of fuel, this is the figure used for fuel input.
Calculate AFUE Rating:
Plug the heat output and fuel input values into the AFUE formula. For example, if a furnace has a total heat output of 100,000 BTUs and consumes 120,000 BTUs of fuel, the AFUE rating would be (the below calculation indicates that 83.3% of the fuel is converted into usable heat, while 16.7% is lost).
Fuel Prices and Trends:
The cost of fuel varies depending on market trends. As of 2024, natural gas prices can fluctuate significantly, impacting operational costs. Efficient systems with higher AFUE ratings help mitigate these fluctuations by reducing overall fuel consumption. In the last few years, natural gas prices have increased steadily, to check your local prices click here.
BTUs and Load Calculations
To ensure the heating system meets the building's needs, perform load calculations to determine the required BTUs. This involves assessing the building’s size, insulation, and climate. Proper load calculations ensure that the system is neither oversized nor undersized, optimizing efficiency and comfort.

Both SEER and AFUE ratings are critical in determining energy costs. Higher ratings indicate better efficiency, which can significantly reduce electricity and fuel expenses. For instance, upgrading to a higher SEER or AFUE system can lead to substantial savings on utility bills over time, benefiting your business’s bottom line.
AFUE stands for Annual Fuel Utilization Efficiency. It measures the efficiency of heating systems like furnaces and boilers by comparing the amount of heat produced to the amount of fuel consumed over a year. A higher AFUE rating means better efficiency and lower fuel costs. For example, an AFUE of 90% means that 90% of the fuel used is converted to heat, while 10% is lost.
As of January 1, 2023, the US Department of Energy (DOE) implemented new minimum energy efficiency standards for HVAC equipment, including changes to SEER and AFUE ratings.
Here's a summary of the key changes:
SEER (Seasonal Energy Efficiency Ratio):
-
Northern states: Minimum rating increased from 13 SEER to 14 SEER (13.4 SEER2).
-
Southern states: Minimum rating increased to 15 SEER (14.3 SEER2).
-
Split systems using less than 45,000 BTU: Minimum rating of 15 SEER.
-
Split systems using more than 45,000 BTU: Minimum rating of 14.5 SEER.
-
Heat pumps: Minimum nationwide rating of 15 SEER (14.3 SEER2).
AFUE (Annual Fuel Utilization Efficiency):
-
All regions: New standard from 80% to 81%AFUE.
Other changes:
-
The HVAC industry is adopting the SEER2, EER2, and HSPF2 rating standards.
-
Air conditioning systems will use the safer refrigerant R-454b instead of R-410a, which has a high global warming potential.
No, The requirements for SEER2 ratings vary by region due to different climate conditions across North America.
The Heating Seasonal Performance Factor (HSPF) is a metric used to evaluate the efficiency of heat pumps, specifically their heating performance over an entire heating season.
When selecting a new HVAC system, consider:
-
The SEER and AFUE ratings for energy efficiency.
-
The size and capacity suitable for your space.
-
Features like variable-speed motors and advanced controls.
-
Manufacturer reliability and warranty options.

SEER Energy Savings Calculator
What is SEER rating for HVAC?
Seasonal Energy Efficiency Ratio (SEER) is a key metric in HVAC systems that measures how efficiently air conditioners and heat pumps cool a space over a typical cooling season. Expressed as a ratio of cooling output (in BTUs) to the energy consumed (in watt-hours), SEER provides insight into the energy efficiency of these systems. For businesses, understanding SEER is crucial as it directly influences energy costs, operational efficiency, and environmental impact. Higher SEER ratings indicate more efficient systems that can reduce electricity bills and contribute to long-term savings. Additionally, investing in high-SEER HVAC systems can help businesses comply with energy regulations, achieve sustainability goals, and enhance overall comfort and reliability in their facilities.
How to Calculate a SEER Rating
Understand the Formula:
SEER is calculated by dividing the total cooling output (measured in British Thermal Units or BTUs) by the total electrical energy input (measured in watt-hours) over a typical cooling season. The formula is:
Measure Cooling Output:
The cooling output of the HVAC system is the total amount of heat removed from the indoor air during the cooling season. This is usually provided by the manufacturer in BTUs.
Determine Electrical Energy Input:
Calculate the total electrical energy consumed by the HVAC system over the same period. This involves measuring the power usage of the system, usually in watt-hours.
Calculate SEER Rating:
Plug the cooling output and electrical energy input into the SEER formula. For example, if an HVAC system has a total cooling output of 36,000 BTUs and uses 12,000 watt-hours of electricity, the SEER rating would be:
Compare Ratings:
When shopping for HVAC systems, compare SEER ratings to find the most energy-efficient option. Higher SEER ratings translate to greater energy efficiency and potential cost savings on electricity bills.
