The current industry minimum SEER rating is 13 SEER.

In 2011 Frigidaire was again awarded by Consumers Digest the Best Buy award for the iQ Drive 24. 5 Air Conditioner, which remains the highest SEER rating in the heating and cooling industry.

The higher the unit's SEER rating the more energy efficient it is.

The SEER is thus calculated with the same indoor temperature, but over a range of outside temperatures from 65 to 104 degrees F, with a certain specified percentage of time in each of 8 bins each spanning 5 degrees F. There is no allowance for different climates in this rating.

SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system ’ s energy efficiency at one specific operating condition.

The United States now requires that residential systems manufactured after 2005 have a minimum SEER rating of 13, although window units are exempt from this law so their SEERs are still around 10.

The annual cost of electric energy consumed by a ( 6 ton ) air conditioning unit, operating for 1000 hours per year, with a SEER rating of 10, and an electric energy cost of $ 0. 12 per kilowatt-hour ( kW · h ) is:

A residence near Chicago has an air conditioner with a cooling capacity of 4 tons and an SEER rating of 10.

In the United States, SEER is computed by measuring cooling in British thermal unit ( BTU ) and energy consumed in watt-hours, so the resulting number is measured in units of 0. 29307107.

For example, consider a air-conditioning unit, with a SEER of 10 BTU / W · h, operating for a total of 1000 hours during an annual cooling season ( e. g., 8 hours per day for 125 days ).

A SEER of 13 is approximately equivalent to an EER of 11, and a COP of 3. 43, which means that 3. 43 units of heat energy are removed from indoors per unit of work energy used to run the air conditioner or heat pump.

: unit size, BTU / h × hours per year, h × energy cost, $/ kW · h ÷ SEER, BTU / W · h ÷ 1000 kW / W

To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER is used, the Seasonal Energy Efficiency Ratio ( SEER ), or in Europe the ESEER.

In cooling mode, a heat pump's operating performance is described in the US as its energy efficiency ratio ( EER ) or seasonal energy efficiency ratio ( SEER ), and both measures have units of BTU /( h · W ) ( 1 BTU /( h · W ) = 0. 293 W / W ).

The SEER Centre in Scotland is a leading source of information on the use of rock dusts and mineral fines.

The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio ( SEER ) which is defined by the Air Conditioning, Heating and Refrigeration Institute in its standard ARI 210 / 240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

In most countries, the SEER is a unitless ratio, as both cooling energy and energy consumed are measured in the same units.

SEER is a higher value than EER for the same equipment.

Today, 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.

For example by upgrading from SEER 9 to SEER 13, the power consumption is reduced by 30 % ( equal to 1 − 9 / 13 ).

The manufacturer's literature should provide both a COP to describe performance in heating mode, and an EER or SEER to describe performance in cooling mode.

For most applications, the minimum or near-minimum SEER units are most cost effective, but the longer the cooling seasons, the higher the electricity costs, and the longer the purchasers will own the systems, the more that incrementally higher SEER units are justified.

The Seasonal Energy Efficiency Ratio ( SEER ) has the same units of Btu / W · hr, but instead of being evaluated at a single operating condition, it represents the expected overall performance for a typical year's weather in a given location.

To this day, lymphoma statistics are compiled as Hodgkin's vs non-Hodgkin lymphomas by major cancer agencies, including the National Cancer Institute in its SEER program, the Canadian Cancer Society and the IARC.

The National Program of Cancer Registries was established by Congress through the Cancer Registries Amendment Act in 1992, and administered by the Centers for Disease Control and Prevention ( CDC ).. NPCR and SEER together collect cancer data for the entire U. S. population.

The SEER and EER of an air conditioner are limited by the laws of thermodynamics.

The maximum SEER can be calculated by averaging the maximum EER over the range of expected temperatures for the season.

With a SEER of 10 BTU / W · h, the annual electrical energy usage would be about:

SEER ratings are based on seasonal temperature averages instead of a constant 35 ° C outdoor temperature.

In 2010 Frigidaire was awarded the Consumers Digest Best Buy award for their iQ Drive 22 SEER Heat Pump.

In 1973, The Surveillance, Epidemiology and End Results ( SEER ) Program of NCI establishes the first national cancer registry program.

The Surveillance, Epidemiology, and End Results ( SEER ) Program of the National Cancer Institute collects and publish data on cancer incidence and survival throughout the United States.

The SEER program population-based cancer registries include Arizona Indians, Cherokee Nation, Connecticut, Detroit, Georgia Center for Cancer Statistics ( Atlanta, Great Georgia, and Rural Georgia ), Greater Bay Area Cancer Registry ( San Francisco-Oakland and San Jose-Monterey ), Greater California, Hawaii, Iowa, Kentucky, Los Angeles, Louisiana, New Jersey, New Mexico, Seattle-Puget Sound, and Utah.
