Operating Costs

Below is the calculation of the operating costs of a 5 ton Furnace manufactured in 1990. By upgrading to just a 15 seer system today, the utility savings are substantial over the next 20 years. If unit was downsized because of enhancements to the home (such as double pane windows) the savings would be even greater.
