Heating Performance
Furnace wins below 25°F. Gas burns hot — 120-140°F supply air. Modern heat pumps work down to 5°F with cold-climate models, but supply air runs 95-105°F. Most NJ winters favor heat pump 80%+ of season.
Short answer for Central NJ: heat pumps win on efficiency, rebates, and dual-purpose (heat + cool); gas furnaces win on raw heating output during single-digit winter nights. The right pick depends on your insulation, ductwork, and whether you also need AC replacement.
Six categories that matter most when picking between heat pump and gas furnace in NJ.
Furnace wins below 25°F. Gas burns hot — 120-140°F supply air. Modern heat pumps work down to 5°F with cold-climate models, but supply air runs 95-105°F. Most NJ winters favor heat pump 80%+ of season.
Heat pump wins — it IS your AC. Furnace heats only; you still need a separate AC unit. One heat pump replaces both, cutting equipment and install costs.
Gas furnace + AC: ~$1,800/yr typical. All-electric heat pump: $1,400-$1,700/yr at current PSE&G/JCP&L rates. Heat pump wins by $100-$400/yr for most NJ homes.
Gas furnace + new AC: $11,000-$18,000 combined. Heat pump system: $12,000-$22,000 standalone (replaces both). Net cost: roughly equal — heat pump wins after rebates (see next).
Heat pump crushes here. Federal tax credits and state/utility rebates may be available for heat pumps — ask us about current programs. NJ Clean Energy and utility rebates can total $2,000-$4,500 on qualifying systems. Furnace rebates: typically lower. See how we help with rebate documentation.
Furnace: 15-25 years. Heat pump: 12-18 years (runs year-round). Tune-up cost similar. Heat pumps need 2 tune-ups/yr; furnace needs 1. seasonal maintenance covers both.
