Before buying a new furnace, make low-cost energy efficiency improvements to the home or building. For example, add insulation and make sure windows and ducts are tightly sealed and do not leak air. Energy efficiency improvements will save money on the furnace, because the home or building will need a smaller furnace.

Hire a contractor to run a heat-loss, heat-gain calculation to accurately size the new furnace. Among other important considerations, make sure that the calculation takes into account:

  • Size and configuration of the home
  • Levels of insulation in walls, ceilings and between floors
  • Number and type of windows in the home
  • Orientation of the home to the sun
  • Ask for an ENERGY STAR qualified furnace

Maintenance

Replace or clean filters regularly and keep your furnace running smoothly with periodic tune-ups. Keeping your furnace clean, lubricated and properly adjusted can help you save on heating costs.
