The Department of Energy is proposing a new rule that would raise the energy efficiency standards for home furnaces. Under the terms of the new rule, non-weatherized gas furnaces, along with those used in mobile homes, would have to achieve an annual fuel utilization efficiency of 95 percent.
This revision stands as the first revision to these guidelines since the Reagan administration which set fuel efficiency standards for mobile home furnaces at 75 percent, with the remainder being set at 78 percent.
Currently, the proposal has entered a 60-day comment period, and should the Department of Energy elect to proceed, the new rule will go into effect in 2029.
