I just move in to a new home and the electric cost is so expensive. I really conserve energy usage, I use floursent bulb and turn it off when I don’t need it. the only thing is the air conditioning unit is a left over from the previous owner, and she said this is probably bought in the late 80′s, so I wonder will it help the electric bill if I use a newer air conditioner, and how much will I probably save from it?

SEER in 1978 was around 7, today it is around 13.
YR. – SEER
’78 – 7.3
’80 – 7.6
’81 – 7.8
’82 – 8.3
’84 – 8.7
’87 – 8.9
’90 – 9.3
’93 – 10.6
’97 – 10.7
’06 – 13
’07 – 14
’08 – 15 to 23
SEER (Seasonal Energy-Efficiency Rating) is a comparative indicator of an air conditioner’s efficiency. The typical central air conditioning system of the early 1990s had a SEER of about 6. It rose to 10 early in this decade. All central air conditioners manufactured since January 23, 2006 must have a SEER of 13 or higher. Older unsold units were grandfathered under this government regulation. At this point, if any of those units are still available, they represent false economy. Guides that recommend them as a budget alternative are out of date. Current central AC units have SEER ratings that range from 13 to 23. The rating can be easily understood as a percentage. For instance, a 14 SEER air conditioner is 40 percent more efficient than a 10 SEER air conditioner.
