Central Natural Gas Furnace Rebates

Rebate Information

The energy efficiency of a natural gas central furnace is measured by the Annual Fuel Utilization Efficiency (AFUE) rating.

Depending on where you live and the overall size of a properly sized and installed central natural gas furnace of 92% AFUE (or greater), an energy efficient natural gas furnace will use about 20% less energy than a standard model (80 AFUE).

• REBATE - $200 per ENERGY STAR® qualified Central Natural Gas Furnace*
  • * An AFUE rating of 92% or greater is needed to qualify. Not all ENERGY STAR labeled units qualify for an SDG&E rebate.

About Central Furnace Heating Systems

Central furnace heating systems usually have a furnace, an air distribution system and the controls. Your furnace burns fuel – typically natural gas – to create heat, which is then transferred to air and distributed through a duct system. Older forced air furnaces as well as, wall, room, and floor furnaces have energy wasting standing pilot lights instead of the newer electronic ignition systems that are available today.

Duct Testing

When considering your home heating system, it is also important to think about duct testing.

• Studies indicate that 10%-30% of the heated or cooled air is lost, along with the money spent to heat or cool that air, through leaky ducts.
• Properly sized, installed, and sealed ductwork will make your heating and cooling systems significantly more efficient.
