seer rating chart
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. Trane air conditioners range from 14.5 SEER up to 22 SEER. In 1987 legislation taking effect in 1992 was passed requiring a minimum SEER rating of 10. Bear in mind that an air conditioning system will not always perform to its SEER rating. What is the annual cost of the electric energy required to operate the air conditioner? SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER rating, the less energy your air conditioner consumes. Electric power is usually measured in kilowatts (kW). 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. is the indoor temperature and The minimum standard SEER for air conditioners is 13, though most modern air conditioners have a SEER that ranges from 13 to 21. It is calculated by dividing the cooling capacity in BTUs per hour (BTUH) by the power input in watts. Privacy Policy. In 2011 the US Department of Energy (DOE) revised energy conservation rules to impose elevated minimum standards and regional standards for residential HVAC systems. Currently, the minimum SEER and HSPF that you can buy are: SEER 13; HSPF 7.7; If you buy an air source heat pump with a higher SEER rating, it will usually have a higher HSPF rating, too, but make sure you focus on the latter number if your heating load is higher than your cooling load. But actually, AFUE is easier to understand than its AC rating counterpart. 93 – 83 = 10 +10 = 2 SEER points; SEER-14 rating – 2 SEER points = SEER-12 rating, or the equivalent SEER rating calculated for your climate area. ENERGY STAR® qualified central air conditioners must have a SEER rating of 14.5 to qualify. In the case of cold climates, water or ground source heat pumps are the most efficient solution. The U.S. Department of Energy enforces minimum SEER requirements that differ by geographical region. It may also be called a Seasonal Energy Efficiency Rating. For the European definition, see, Calculating the annual cost of electric energy for an air conditioner, US Department of Energy Framework Public Meeting for Residential Central Air Conditioners and Heat Pumps (June 12, 2008) at 35– 36 (transcript), European seasonal energy efficiency ratio, Air Conditioning, Heating, and Refrigeration Institute, Learn how and when to remove this template message, "ANSI/AHRI 210/240-2008: 2008 Standard for Performance Rating of Unitary Air-Conditioning & Air-Source Heat Pump Equipment", Air Conditioning, Heating and Refrigeration Institute, "U.S. DOE Building America House Simulation Protocols, Revised October 2010", http://www.eesi.org/papers/view/fact-sheet-air-conditioner-efficiency-standards-seer-13-vs.-seer-12, http://www.mikesheatingandairconditioning.com/13seermandate.htm, "DOE Finalizes New Energy Conservation Standards for Residential HVAC Appliances", "Carrier Launches the Most Efficient Air Conditioner You Can Buy in America", "9,000 BTU 42 SEER Carrier Single Zone Heat Pump System - 230 Volt - High Wall", "Most Energy-efficient Ductless Model on Market Provides Significant Heating Capacity in Extreme Cold Climates", https://www.multivu.com/players/English/8251451-carrier-most-efficient-air-conditioner-ces/, "Inverter Smart Source Unit Just Released up to 62.5 EER that's up to 75 SEER", A new measure for the energy efficiency of heating and cooling devices, Climate Impacts on Heating Seasonal Performance Factor (HSPF) and Seasonal Energy Efficiency Ratio (SEER) for Air Source Heat Pumps, https://en.wikipedia.org/w/index.php?title=Seasonal_energy_efficiency_ratio&oldid=991474573, Heating, ventilation, and air conditioning, Wikipedia articles with style issues from October 2011, Articles with unsourced statements from November 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 30 November 2020, at 06:55. The SEER is thus calculated with the same indoor temperature, but over a range of outside temperatures from 65 °F (18 °C) to 104 °F (40 °C), with a certain specified percentage of time in each of 8 bins spanning 5 °F (2.8 °C). But don’t forget — this rating is a maximum. AHRI lists the certified energy efficiency ratings for specific equipment in its online AHRI Directory of Certified Product Performance. The higher the SEER rating of your system, the less energy it will consume. The same goes for your air conditioner. There’s no magic SEER number. A higher SEER rating means greater energy efficiency. [10] Carrier launched a 42 SEER ductless air conditioner during 2018 Consumer electronic Show (CES), held in Las Vegas. For most units, the SEER rating is located on the outside of the unit. [4] It is rare to see systems rated below SEER 9 in the United States because aging, existing units are being replaced with new, higher efficiency units. Beginning Jan. 1, 2016 central air conditioners sold in the United States are required to have the following minimum SEER: 1. A 13 or 14 SEER rating doesn’t necessarily mean a unit is inefficient. The SEER is complicated by other factors such as the “cooling load,” which is related to how many ve… [6], There have been many new advances in efficient technology over the past 10 years which have enabled manufacturers to increase their SEER ratings dramatically in order to stay above the required minimums set by the United States department of energy. A higher SEER rating provides greater energy efficiency in certain conditions. The maximum SEER can be calculated by averaging the maximum EER over the range of expected temperatures for the season. For example, there is little cost benefit in having a very high SEER air conditioning unit in Maine, a state in the northeast US. Since there is 12,000 BTU’s in a ton of refrigeration, then a model number with a 018 would be 18 divided by 12 which would equal 1.5 tons. The EER is calculated by multiplying the COP by 3.412 BTU/W⋅h as described above: Assuming an outdoor temperature of 95 °F (35 °C) and an indoor temperature of 80 °F (27 °C), the above equation gives (when temperatures are converted to Kelvin or Rankine) a COP of 36, or an EER of 120.

This label is the EnergyGuide tag that lists the SEER rating of your unit. ** Substantial energy savings can be obtained from more efficient systems. California, for instance, has a minimum SEER requirement of SEER 14. "Cold climate" heat pumps are designed to optimize efficiency below 0 °F (−18 °C). Where Is My SEER Rating? 1 ton of cooling equals the amount of power that needs to be applied continuously, over a 24-hour period, to melt 1 ton of ice. T SEER Heat Pump Ratings. Higher SEER units often have 2 components that provide greater indoor comfort. This is how it simulates a typical season. 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. SEER is a higher value than EER for the same equipment.[1]. One of the most confusing parts of buying a new air conditioner is understanding the SEER. The SEER is based upon the energy it takes to remove a certain amount of heat from a room. 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. The SEER of a heat pump or a/c system is the result of the combination of the performance of both the condenser and air handler, so the actual SEER listed on the contractor’s performance data sheet or the building permit may be slightly higher or lower than the SEER rating of the condenser alone. For example, by upgrading from SEER 9 to SEER 13, the power consumption is reduced by 30% (equal to 1 − 9/13). Trane air conditioners range from 14.5 SEER up to 22 SEER. Beginning in January 2006 a minimum SEER 13 was required. 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. SEER, which is short for Seasonal Energy Efficiency Ratio, is a rating system used to measure an air conditioning system’s cooling output during a cooling season, divided by the total electric energy the system uses during the same period. Air conditioners with lower SEER ratings are usually single-stage and only run on one speed. The unit is operated 120 days each year for 8 hours per day (960 hours per year), and the electric energy cost is $0.10 per kilowatt-hour. This is the most common measurement by which consumers measure the energy efficiency of the heat pump that they want to buy. Goodman 14 SEER Sound Ratings. This would mean that an HVAC unit with a SEER rating of SEER-14 would have an equivalent rating of SEER-12 in Santa Clarita. Electric energy is usually measured in kilowatt-hours (kWh). In heating mode, the coefficient of performance is the ratio of heat provided to the energy used by the unit. 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. AC unit with a 10 EER rating has a 13.86 SEER rating. Even with a high SEER rating, it’s still helpful to use other. h, then your cost per operating hour is: The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTU/hr) to input electrical energy (in Watts) at a given operating point. But when either replacing equipment, or specifying new installations, a variety of SEERs are available. Electric energy is usually measured in kilowatt-hours (kWh). But don’t forget — this rating is a maximum. A heat pump with a higher SEER rating for cooling mode would also usually be more efficient in heating mode, rated using HSPF. The higher the number, the less electricity the air conditioner or heat pump consumes. Ahri lists the certified energy efficiency Ratio, is an seer rating chart efficiency Ratio ), held in Vegas!
