To
Use This Chart:
Estimate
the approximate cooling efficiency of your current air conditioner.
If it's more than 10 years old, the efficiency is likely
to be about 6.0 SEER. Then estimate your current annual
cooling cost based on your total electric bill, eliminating
the cost of other electricity use. Use the chart to estimate
how much you can save with a higher efficiency system.
Example:
If your
current air conditioner has a SEER of 6.0 and your annual
operating cost is $600, the cost to operate a new 14 SEER
system, under the same conditions, will be approximately
$260, giving you an estimated annual saving of $340.
