Find Your Air Conditioner's S.E.E.R.

The chart below traces the history of the S.E.E.R. for residential air conditioners and heat pumps:

The History of S.E.E.R.
Seasonal Energy Efficiency Rating

Before 1980

6 or less

1980 to 1985

7 or less

1986 to 1991

8 or less

1992 to 2005

10 to 12

2006 to present

13* or more

 

*Minimum U.S. allowable. If you're not sure when yours was installed,
find the model number on the nameplate of your unit, and give us a call at 508-428-0974. 

As the number increases, your energy use for the same level of cooling decreases proportionally. That means that a 14 S.E.E.R. unit installed today will use half the energy of a 7 S.E.E.R. unit installed in the 1980s. A new 16 S.E.E.R. unit installed today will be 60% more efficient than a 10 S.E.E.R. system from the early 1990s.

These next charts illustrate the savings owners can expect from a high efficiency replacement in a typical 2,000 sq. ft. Cape Cod home:

Philadelphia area home to 70°F from May through early September at Eversource's 6/2015 rate of $0.152 per kWh. Figures here are adjusted to U.S. Department of Energy estimate of 729 cooling days in the greater Boston, MA area vs 1032 in Phila.

In fact, your actual savings are likely to be much higher than these estimates with a Balanced HVAC installation. Here’s why:

The estimates assume:

  • That the system you are replacing was installed properly. The U.S. Department of Energy estimates that “nearly half of all heating and cooling in the U.S. never performs to its advertised capacity due to incorrect installation.”
  • That it has been maintained regularly. A neglected system typically loses between 3% and 10% efficiency per year.
  • That your ductwork is properly designed and not leaking due to poor installation, aging seals or foundation settlement. The U.S. Department of Energy warns that such leaks rather than the equipment itself are “the real source of (energy efficiency) problems.”
  • That your system has been properly balanced. (Most technicians don't have the skills.) 
  • Your system uses a standard thermostat.Addition of a programmable thermostat can increase efficiency even more.

With your installation by Balanced HVAC, you are assured maximum comfort and energy efficiency.
