What Your A/C SEER Rating Actually Means

When an HVAC unit works efficiently, it will consume less energy as it makes your home feel comfortable. A factor that helps you determine an air conditioner’s efficiency is its Seasonal Energy Efficiency Ratio (SEER) rating. In general, the higher the rating, the more efficient the cooling equipment is. Each state has a minimum SEER rating standard for new air conditioning units, which is 13 or 14 SEER.  Understanding what this rating means for you before an A/C installation will help you make an informed decision about the cooling unit that best meets your needs.

What Exactly is a SEER Rating pexels-photo-29748

SEER ratings are ratios derived by calculating the annual cooling output during the cooling season divided by the total electric energy input. The total cooling output is the A/C’s British thermal unit per hour (BTU/h) multiplied by the number of cooling hours per day and the number of cooling days per year. For example:

6,000 BTU/h x 10 cooling hours per day x 200 days per year = 12,000,000 BTUs per year

Using the example above, if an air conditioner has a SEER rating of 15 BTU per watt-hour (Wh), you could calculate the estimated annual energy use as follows:

12,000,000 BTUs per year ÷ 15 BTU/Wh = 800,000 Wh per year

To calculate the annual average power use, divide the A/C’s BTU/h by the SEER rating. For example:

6,000 BTU/h ÷ 15 SEER = 400 watts (or 0.4 kilowatts)

To calculate the cost of electricity when using the A/C, multiply the average kilowatts from the formula above by your local electricity rate in kilowatts per hour (kWh). For instance, 0.4 kW x $0.25 kWh = $0.10 per hour. The EnergyGuide label on the HVAC unit will also indicate the amount of energy the equipment consumes.

History of SEER Ratings

Universal standards of measurement to rate the efficiency of HVAC equipment did not exist until recently. In 1992, the government established minimum standards for air conditioning units manufactured in the U.S. In the early 1990s, it was common for HVAC equipment to have SEER ratings of around 8 or 9. The Energy Policy Act of 2005 updated the minimum standard to 13 SEER. Each state, however, has the right to set its own minimum standard, as it is not below 13 SEER.

While today’s minimum ratings of 13 or 14 SEER might seem low, they are superior in regards to efficiency when compared to units with an 8 or 9 SEER. Therefore, if you want to replace a 20-year-old air conditioner with a new one that has the minimum SEER rating, there’s a good chance that your energy efficiency will improve instantly.

How SEER Ratings Affect Your A/C Unit

Before an A/C installation, keep in mind that a SEER rating indicates the unit’s maximum potential. This means that when a unit states that it has a value of 21 SEER, for example, the rating can be as high as 21 SEER. It will not always perform at 21 SEER because the laws of thermodynamics limit the rating. Various factors affect an air conditioner’s efficiency and performance, including sun exposure, outdoor temperatures, thermostat settings, building envelope and mechanical problems.

SEER ratings are variable, which means that HVAC units with the highest SEER values may not save you money in the future or “pay for themselves.” If equipment rated at 21 SEER performs at an average of 15 SEER, it may be wiser to save money and purchase an A/C with a lower SEER rating. An HVAC specialist can help you determine the most appropriate SEER rating for your new A/C unit using special equations that average the maximum Energy Efficiency Raito (EER) over the range of expected seasonal temperatures. In general, good SEER values for residential air conditioners are 14 to 16.

Other Factors to Consider in an A/C Unit

While SEER ratings are an important factor when buying an air conditioner, it is also necessary to consider:

  • Your budget
  • The size of your home
  • The size of the air conditioning unit and its air handling capacity; a specialist will tell you the exact size you need
  • Your area’s climate
  • The length of the cooling season
  • The amount of time you spend at home
  • The number of hours you plan to use the A/C per day
  • The indoor temperatures that you prefer
  • EER ratings
  • Quiet operations
  • The presence of fan-only switches, which would allow you to circulate air in your home without conditioning it
  • Automatic-delay fan switch that turns off the fan shortly after the compressor turns off
  • Ease of maintenance
  • Lifetime costs, including energy, maintenance and repairs
  • A unit’s quality and life expectancy
  • The manufacturer’s history of reliability
  • Warranty terms

The implementation of SEER ratings have made air conditioners more energy efficient and Earth-friendly, creating a win-win situation for all.

From 1990 to 2000, appliance efficiency standards reduced consumer energy bills by approximately 50 billion dollars. As of 2000, the standards reduced U.S carbon emissions from fossil fuel consumption by nearly two percent. While equipment prices have modestly risen under the standards, Lawrence Berkeley National Laboratory research indicates that the benefit energy savings are more than three times the cost on a net-present value basis. In 2000, standards reduced the peak generating needs by approximately 21,000 megawatts (MW), which is the same as seventy 300 MW power plants. As old appliances are replaced by new ones the positive impact of the energy efficiency standards will continue to grow. From 1990 to 2030, it is estimated that consumers and businesses will save approximately $186 billion (1997 dollars) just from the existing standards that have been adopted. Currently, the debate concerning appliance efficiency standards has revolved around the Bush Administration’s proposal to weaken the standard for air conditioners from the SEER 13 standard set by the Clinton Administration to a SEER 12.

What is SEER? How does it apply to the energy efficiency of air conditioners?

The efficiency of central air conditioning units is governed by U.S. law and regulated by the U.S. Department of Energy (DOE). Every air conditioning unit is assigned an efficiency rating known as its “seasonal energy efficiency ratio” (SEER). The SEER is defined as the total cooling output (in British thermal units or Btu) provided by the unit during its normal annual usage period divided by its total energy input (in watt-hours) during the same period.

Why is air conditioner efficiency currently an issue?

After finalizing a seven-year public review process, the Clinton Administration improved the air conditioner efficiency standard from SEER 10, which was established by Congress in 1987, to SEER 13. The change from SEER 10 to SEER 13 represented a 30 percent improvement in energy efficiency. The Clinton Administration decision required all new air conditioning equipment sold in the United States to comply with the SEER 13 standard by January 2006. In April 2001, however, the Bush Administration addressed the possibility of weakening the standard to SEER 12, and in July, DOE formally proposed to roll back the standard. 

Prior to the August recess, the House of Representatives passed H.R. 4, the “Securing America’s Future Energy (SAFE) Act of 2001.” In H.R. 4, the House followed the Bush Administration and passed a weakened standard for air conditioners of SEER 12, instead of SEER 13. 

In October 2001, the U.S. Environmental Protection Agency (EPA) officially commented on the DOE proposed roll back ruling. EPA stated that DOE overstated the regulatory burden and the financial pressures on the air conditioning industry and understated the savings benefits of the SEER 13 standard. The Deputy Administrator of EPA stated, “EPA believes there is a strong rationale to support a 13 SEER standard.” 

The issue of SEER 13 vs. SEER 12 now stands before the Senate to be addressed when the “Energy Policy Act of 2002” (S.517) is considered on the Senate floor. S.517 contains a provision setting a SEER 13 air conditioner efficiency standard (Sec. 927), but a motion to strike or weaken Sec. 927 is expected.

What is gained in making a SEER 13 standard rather than a SEER 12?

According to EPA, a SEER 13 standard represents a 30 percent increase in minimum energy efficiency requirements for air conditioners, in contrast to a 20 percent increase with a SEER 12 standard. According to DOE, 4.2 quadrillion Btu, or quads of energy, will be saved between 2006 and 2030 by a SEER 13 standard. 4.2 quads of energy is the equivalent to the annual energy use of 26 million U.S. households, which has a net savings of approximately $1 billion to the consumer by 2020. On the other hand, a SEER 12 standard will only save three quads of energy during the same time period. 

A SEER 13 standard will also accomplish more in reducing fossil fuel consumption and limiting air pollution. The construction of 39 400-megawatt power plants will be avoided by adopting the SEER 13 standard, which will reduce smog forming nitrous oxides (NOx) emissions by up to 85,000 metric tons and cutting greenhouse gas emissions (the gases responsible for global warming) by up to 33 million metric tons (Mt) of carbon. In contrast, a SEER 12 standard would only avoid the construction of 27 400-megawatts power plants, reducing 73,000 metric tons of NOx and 24 Mt of carbon. Power plants are major sources of greenhouse gases and the emissions that cause smog, acid rain and soot pollution. At a time when many areas throughout this nation are struggling to improve their air quality and public health the differences in avoided emissions between SEER 13 and SEER 12 are significant. Since air conditioners run most on hot days, the rollback would increase pollution precisely when air quality problems are at their worst. 


What are the Myths about the SEER 13 standard…what are the FACTS? 

Myth #1: The SEER 13 standard hurts low-income families.

  • The incremental cost of improved efficiency is three to eight percent of current equipment costs. For most families, the extra cost will be made up through lower utility bills within three and a half years. Central air conditioners last about 18 years.
  • Most low-income families with central air conditioning rent their homes, so they benefit from the energy savings but do not bear equipment costs. 
  • Relatively few low-income families actually ever purchase or own a central air conditioner, a product that costs between $2,000 and $5,000. 
  • Saving money on monthly utility bills is just as important for low-income families as for wealthier people, which is why consumer and low-income advocacy organizations like the Consumer Federation of America, the National Consumers League, the National Consumer Law Center and several state community action agencies support the SEER 13 standard.

Myth #2: Utility bill savings will not cover the cost of going to a SEER 13 standard. 

  • The American Council for an Energy-Efficient Economy (ACEEE) estimates that the incremental cost of a SEER 13 unit relative to today’s minimum standard SEER 10 unit will be about $171. With typical household savings of $48 per year based on current national average electricity prices, the higher standard pays for itself in about 3.5 years. Central air conditioners last about 18 years. 
  • If prices for power go up (particularly in the summer), the consumer payback will be even quicker. 
  • History shows that manufacturers’ predictions of huge price increases due to higher standards prove false. In the 1980s, the air conditioner industry predicted that the 1992 standard would increase prices by more than $700. U.S. Department of Commerce data show that prices did not go up at all. Now, some manufacturers are again claiming a new standard will increase prices by more than $700.
  • The truth is that the market determines prices, not industry or government projections. When faced with the need to compete for the business of price-conscious consumers, manufacturers have a very good track record of meeting standards with minimal price increases. 

Myth #3: The higher standard will prevent people from replacing their old air conditioners because of the extra cost.As a result, people will stick with old, inefficient air conditioners causing the nation to use more energy.
FACT: SEER 13 adds three to eight percent to the cost of a purchase relative to a SEER 10 unit. When compared to the weaker SEER 12 standard that some in the industry and the Bush Administration support, the price difference is even smaller (about 2 to 4 percent). It would seem unlikely that droves of consumers will decide to repair rather than replace an old broken-down energy-hog system over such a small price differential on a $2,000 to $5,000 purchase.

Myth #4: SEER 13 units are much bigger than SEER 10 or SEER 12 units, so major renovations will be required to fit them into existing homes. 
FACT: Some SEER 13 units are significantly bigger, but many are not. For example, Goodman Manufacturing makes SEER 13 units using non-proprietary technology that are only about three inches larger than their basic units. The size of the unit depends on the technologies that a manufacturer uses to improve efficiency; SEER 13 units of all sizes are made now and will be available in the future.

Myth #5: The higher standard is burdensome for small manufacturers. 

  • Much of this claim is based on specialty products for markets like manufactured housing, where pace constraints limit efficiency with conventional technology. However, DOE said in the final rule that it was open to exemptions, which is a more appropriate way to deal with such situations than weakening the standard across the board.
  • Goettl Air Conditioning, a small manufacturer based in Arizona, supports the stronger standard. Goettl notes that SEER 13 technology will have been made widely available for more than a decade to all manufacturers by 2006 when this standard becomes effective. 

Myth #6: Eighty-four percent of all models currently sold will be eliminated.

  • While true, this should not be surprising; 95 percent of refrigerator models sold in 1997 were eliminated by the refrigerator standard that went into effect in July 2001, and the appliance manufacturers support that standard.
  • Most units sold today just meet the current minimum standard. In today’s market, SEER 13 units are premium products sold with high markups to less price conscious consumers. Once the new standard goes into effect, the vast majority of units will just meet SEER 13, and manufacturers will reestablish new premium lines with higher SEERs and other premium features. 
  • There are hundreds of distinct models on the market today that meet or exceed SEER 13. Some have SEER values as high as 16, 17 and 18. 
  • Over the next five years, the majority of air conditioner models would probably need to be upgraded to remain competitive, even if the standard did not change at all.


The BIG Picture

The rollback to a SEER 12 standard from a SEER 13 would sacrifice about one-third of the energy savings that could be achieved by SEER 13. A SEER 13 standard will decrease national energy consumption, lower summertime utility bills for millions of households, reduce pollution from power plants and improve public health. 


Additional History for Energy Efficiency Standards

Uniform national standards for energy efficiency on an array of products were first put into place in 1987 when President Regan signed the National Appliance Energy Conservation Act (NAECA). In 1988, efficiency standards for fluorescent lamp ballasts were added by Congress, and in 1992, President Bush signed the Energy Policy Act, which added new efficiency standards for certain types of lamps, electric motors and commercial heating and cooling equipment. The first Bush Administration continued to add efficiency standards laying the groundwork for the Clinton Administration to set new standards for refrigerators, air conditioners, ballasts, clothes washers, water heaters, and heat pumps.

What's a Good SEER Rating?

It’s tough to give a quick answer here, because a good SEER rating depends on what you’re looking for in a heating and cooling system.


First, the basics. SEER  stands for Seasonal Energy Efficiency Ratio. This is the ratio of the cooling output of an air conditioner over a typical cooling season, divided by the energy it uses in Watt-Hours. It may also be called a Seasonal Energy Efficiency Rating.

A SEER ratio is calculated over an entire cooling season using a constant indoor temperature and a variety of outdoor temperatures ranging from 60 degrees to 100 plus. This is how it simulates a typical season.

Keep in mind that SEER ratio is a maximum efficiency rating, like the miles per gallon for your car. Say your car gets 28 miles per gallon on the highway. But if you’re stuck in city traffic it’s a lot less efficient. The same goes for your air conditioner. If your SEER ratio is 21, that’s the maximum efficiency and it could be lower depending on conditions.

Benefits of a High SEER Rating or Ratio

Higher Energy Efficiency
A higher SEER rating provides greater energy efficiency in certain conditions. The minimum standard SEER for air conditioners is 13, though most modern air conditioners have a SEER that ranges from 13 to 21. Trane air conditioners range from 14.5 SEER up to 22 SEER. But don’t forget — this rating is a maximum. The efficiency of your system can vary based on the size of your home, your current ductwork and other variables. Even with a high SEER rating, it’s still helpful to use other energy saving tips for the summer season. 

The U.S. Department of Energy enforces minimum SEER requirements that differ by geographical region. The minimum in the Southwest and Southeast is 14 and it’s goes down to 13 in the North. A 13 or 14 SEER rating doesn’t necessarily mean a unit is inefficient. Most older A/C systems are rated at around 8 or 9, so even the lowest available SEER rated system you buy today will be much more energy efficient.

Greater Indoor Comfort
Getting an air conditioning system with a higher SEER does mean you’ll be more comfortable in the summer months, especially if you live in a hot region like the Southeast or Southwest.

Higher SEER units often have 2 components that provide greater indoor comfort.

  • 2-stage or variable-speed compressor
  • Variable-speed blower

Air conditioners with lower SEER ratings are usually single-stage and only run on one speed. This means they’ll frequently turn on and off during mild weather and you’ll experience uneven cooling or hot and cold spots. You’ll also experience higher humidity levels which makes it feel hotter than it is. Your A/C needs to run for a long period of time to remove humidity from your home’s air. The ups and downs of a single-stage system don’t accommodate for this.

So what’s the answer?

There’s no magic SEER number. Anything over 13 is great. Because if you have an old 8 SEER system and replace it with a 16 SEER unit, you could significantly reduce the cost of cooling your home.

Don’t forget to look at tax credits and manufacturer’s rebates that can bring the down the cost of a high SEER system. You can also feel good using fewer fossil fuels, which means fewer greenhouse gas emissions.

If you have more questions about SEER or want to invest in a new cooling system, a local Trane Comfort Specialist can work with you to find an energy saving option that’s the perfect fit for your current home or when your building your new energy efficient dream home.
