Quick answer
A like-for-like furnace keeps gas heat simple. A heat pump adds efficient heating and cooling — often with utility incentives when eligibility is verified. Published ranges: furnaces $3,500–$20,000; heat pumps $9,935–$21,725. The right answer depends on ducts, electrical, comfort goals, and your utility — not a national blog.
- Want cooling + efficiency → heat pump (or dual fuel) usually wins.
- Gas furnace may still fit when electrical capacity or budget constrains conversion.
- PSE/JPUD conversion rebates can change the math — never assume amounts for PenLight/Mason/Tacoma.
- Price both paths in writing before you tear out equipment.
When both paths are live
Your furnace is failing in shoulder season, you're tired of window AC, or a quote only offered one technology.
Compare your options
Furnace replacement
Confirm AFUE, venting for condensing equipment, combustion safety, and duct compatibility. Range spans simple swaps to complex vent/duct upgrades.
Heat pump conversion
Confirm electrical service, duct airflow for lower supply temps, outdoor placement, and rebate paperwork. Dual-fuel retains gas backup when desired.

Choosing furnace-only to 'save money' without pricing heat pump net of rebates
Sometimes the furnace is correct. Sometimes the missing cooling and missed rebate make it the expensive path over 10 years. Compare net numbers.
