Natural gas prices are going higher and I would like to hear some tips on making my house more energy efficient.
Some general details:
Northern IL (west of chicago)
3400 sq ft 5br house 5000 sq ft with basement 23 year old house natural gas furnace.I have already done some obvious things, like made sure that all windows have been closed (incl the "double window" glass slides, not sure what they are called) and draft free, and that the doors are draft free.
I have a vent over my fireplace and I closed off that one.
I would very much like to know if there is something else that I can do, maybe some ideas etc.
thanks
i
