Estimated savings serve solely as an example of the therm and dollar savings that may be achieved by upgrading to high efficiency. Actual savings will vary, and depend on other factors not considered in these calculations. Rebates are available to eligible Nicor Gas customers for the purchase and installation of qualifying equipment. Additional requirements apply.
