In the letter authored by 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 noncondensing 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 noncondensing furnace, the DOE will be forcing many homeowners to either 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.”
