A weatherized home has insulation and air sealing (meaning the cracks, gaps and open seams that leak air have been sealed). Insulation and air sealing are particularly effective in the walls and attic.

If your home has multiple heating sources like a furnace and in-floor electric heat, choose the fuel for your most used source. The calculator does not accommodate other heating fuel types.

Ductwork is a system or network of ducts or tubes that transports air from heating, ventilation and air conditioning (HVAC) equipment throughout your home.

Unconditioned spaces are not directly heated or cooled. Their temperature may be significantly higher or lower than the living areas of your home depending on the season.
