Old house experts?
I am very interested in renewable energy sources, but am having a hard time finding someone who can advise me on what will work for a 98-year old home that was originally heated by a gas gravity system, and now by a gas forced air furnace. We are also planning a two-story addition.
I posted on the HVAC forum and was advised the the existing ductwork in my house would not be suitable for retrofitting a geothermal system, which seemed like a good quasi-renewable option.
On our own, we've done some upgrades that have increased energy efficiency, but feel like we need some expert advice for our Chicago area home. Any thoughts on how to find one?
