My furnace is 19 years old and groaned all last winter. I swore I'd sort it before October, and here we are. Trouble is the 25C credit died 31 December 2025, so a 2026 install gets nothing federal, and a few states have closed or paused their HEAR windows. Like-for-like furnace is thousands cheaper up front. Heat pump wins on running cost if my electric rate behaves, which is the part I can't promise. What would you sign for this month? good luck to us all #heatpump #furnace #energybills #hvac

View on Triopolepull last winters bills and get your actual gas price per therm and your all-in electric rate per kwh, delivery charges included, thats the number that decides this not the sticker. rough rule i use: a therm is about 29 kwh, a decent cold climate unit runs maybe 2.5x efficiency in the cold, so if your electric rate is under about a tenth of your gas price per therm the pump wins on fuel. good catch on the panel, thats a real line item i left out. add it to the ratio: if you need the 200 amp upgrade thats a few grand added to the pump side before the fuel math even starts helping you. still stand by check the rate first, but do it AFTER you get the panel quote, not before, or youre solving for the wrong number entirely idk

Section 25C paid 30 percent of cost, capped at 2,000 dollars for a heat pump and 600 dollars for a qualifying furnace, so the swing was 1,400 dollars. The One Big Beautiful Bill Act, signed 4 July 2025 as Public Law 119-21, ends the credit for property placed in service after 31 December 2025. Live in 2026: state-run HEAR rebates, with a statutory maximum of 8,000 dollars toward a heat pump.

ok but the thing that decides whether your pump is good or miserable is who sizes and commissions it. we got two quotes on the same mid-tier variable speed unit, 3k apart, and the cheap one hadn't measured a single duct. paid for the one who did a manual j and set the refrigerant charge properly and it's quiet and even. premium brand with a lazy install is the worse buy. also get quoted now in september, not december with a dead furnace. emergency pricing is real.

Using Dana's figures as posted in this thread (unverified): furnace 6,000 versus pump 14,000 is 8,000, and at the 400 a year saving Dana quotes that is 20 years. Now count the condenser marcusd33 asked about. Put a like-for-like AC at 5,500. Furnace plus AC is 11,500, so the gap is 2,500, and 2,500 / 400 is 6.25 years. Same unit, same rates. Get the AC quoted separately so the line is visible.

Not a doctor but I do know delays cost money lol - we found out our panel needed upgrading AFTER we'd already picked the heat pump, wasted two weeks. Get that electrician out this week before you commit to anything, it changes the whole math like everyone's saying. Good luck, furnace groaning through another winter sounds rough!

specsheet, that 8,000 number needs an asterisk, my understanding is HEAR is income tested, full amount only under 80 percent of area median and half at 80 to 150, above that you get nothing. so quoting the statutory max as if its on the table is how people end up mad at their contractor. and thollis, whats your AC? if that condenser is also 19 and dying, the pump is replacing two boxes not one and the price gap shrinks a LOT. also whats your panel, anyway

marcusd33's ratio is the right test, but it decides fuel cost only, and fuel is the smaller half of this. A like-for-like furnace at, say, 6,000 versus a cold-climate pump at 14,000 is 8,000 up front; if the pump saves 400 a year you are 20 years to break even, and the unit may not live that long. Dual fuel is the one I would price, because it lets you run the pump when it is cheap and the gas when it is not. Get three quotes with the full electric rate including delivery on paper.

pennywise's 6 year number only holds if the AC is actually dying. if that condenser has five good years left you're paying 14k now to avoid 5,500 later, and that's not the same math. and marcusd33 asked about the panel and nobody answered it. thollis, what's your service and is there a free breaker slot? ours was 100 amp and the electrician wanted 3,400 to go to 200 before anyone touched the hvac. that number lives outside every quote you'll get.

sofiamora is right that the install decides it, but the number that goes with that is the panel. If thollis needs a service upgrade to 200 amps, that is commonly a few thousand on top, and that lands entirely on the heat pump side of my arithmetic, not the furnace side. So before anyone re-runs my 6.25 years, ask: what does the pump need at the panel, and is the dual fuel setup cheap enough to skip that upgrade? Get it quoted as its own line.

Did a heat pump 2 years ago, panel was already 200 amp so I got lucky, didn't have to add that cost. Get the electrician quote before the hvac quote, not after, it changes which system even makes sense.

thollis, did you ever get the panel checked, or is that still unknown? feels like the whole decision hinges on that number.
