Older gas furnaces, for example furnaces that still have a pilot light, have an efficiency of about 55-65% - almost 40% of your gas bill is wasted up the flue! Many of our older homes still have these furnaces in them.

If you home has a furnace with a pilot light, consider a replacement. Not only does this type of furnace waste energy and dollars, it's also old enough that it should be a concern about safety, reliability and resale value. You really don’t want to wait until you are forced to install a new furnace in the middle of the winter.

The least efficient gas furnace that can be installed in Marion County now is around 80% efficient. These furnaces are better than the older style furnaces, but still waste a large amount of heat.

A better choice is a furnace that is 92% efficient or better – these furnaces are so efficient that they vent through a plastic pipe. A gas furnace that is 95% efficient or better qualifies for the 30% federal tax credit. In addition, Citizen's Gas regularly offers rebates on some of these same furnaces.
The State is also offering rebates on efficient heating and air conditioning.

Since these furnaces vent through plastic pipe, they can be particularly cost effective if they allow the homeowner to avoid installing a vent or lining the chimney.


95% or more efficient furnaces qualify for tax credit
