In the letter from U.S. Rep. Mo Brooks, R-Alabama, Brooks and 120 undersigned members of the House — including 116 Republicans and four Democrats — said they are “extremely concerned that requiring the elimination of the economical and efficient non-condensing furnace will place an unnecessary burden on already struggling homeowners in our states,” and that "by setting a nationwide energy efficiency standard that precludes a consumer from choosing to install a non-condensing furnace, DOE will be forcing many homeowners either to abandon the use of natural gas to heat their homes or pay substantially more for the installation of a furnace that meets the new standard."
