Calculation does not include service installation or equipment costs. Appliance costs vary depending on: fuel, age, manufacturer and number
to be converted or replaced, etc. Contact your heating/plumbing contractor for estimates. Installation of higher efficiency appliances increases
savings. A daily facilities charge of 33 cents is included in your monthly bill and is reflected in the estimate above. If the calculator shows
a negative number, switching to natural gas would not be beneficial at this time.
