"Gas or electric" is a broader question than heat pump versus furnace alone, since both gas and electric heating come in a few different forms. Here's an honest look at the real tradeoffs, without pretending there's one universally correct answer for every home.
Gas furnaces
Gas furnaces tend to heat a home quickly and maintain strong performance even in very cold temperatures, since they're not affected by outdoor temperature the way a heat pump is. They require an existing natural gas line, proper venting, and carry the carbon monoxide safety considerations that come with any combustion appliance, which is why regular maintenance matters more here than with an all-electric system.
Electric furnaces
An electric furnace uses resistance heating elements rather than combustion, so there's no gas line or venting required, and no combustion byproducts to worry about. The tradeoff is typically higher operating cost per unit of heat compared to gas, since electric resistance heat is generally less efficient than burning gas directly, though this varies with local utility rates.
Heat pumps
A heat pump moves heat rather than generating it directly, which makes it considerably more efficient than electric resistance heat for most of the heating season, though efficiency drops as outdoor temperatures fall (which is where auxiliary heat comes in, covered in a separate guide). Heat pumps also handle cooling in the summer using the same equipment, which is worth factoring into a full-system decision, not just a heating-only comparison.
What actually determines the right choice
Whether gas is already available at your home, local utility rates for gas versus electricity, how cold your winters realistically get, and whether you're replacing just the heating side or the whole system all factor into a genuinely honest recommendation. This is exactly the kind of decision worth an actual conversation about your specific home and utility costs, not a generic answer that applies to everyone.
