Here in Carlsbad, CA, most homes use gas-fed furnaces to keep warm during the winter. We enjoy mild weather here on the coast, and gas-fed furnaces to the job with a minimum of fuss. But depending upon the circumstances, you may wish to trade in an older gas furnace for a similar model powered by electricity.
Gas furnaces use burners to heat the air, while electric models rely on heated coils powered by your home’s electrical grid. Every home is different of course and not every household can benefit from an electric furnace over a gas-fed one. If you’re in the market, however, it pays to at least give the advantages of electric heating a consideration.
