Can we talk about choosing a heat pump over a new furnace? My numbers after one winter in Boise
When my old gas furnace died in October, I had two quotes sitting on my table: $6,800 for a new 96% furnace or $11,400 for a cold climate heat pump after the $2,000 tax credit. I picked the heat pump because Idaho Power has a $500 rebate and my neighbor swears his bill dropped. First month it got down to 14 degrees and the thing ran nonstop, which scared me, but the electric bill came in at $118 versus the $145 I paid last January with gas. The whole winter averaged out to about $22 a month cheaper, plus no more carbon monoxide worry in the garage. The install crew had to add a return vent in the hallway, which took a full day and a half. Anyone else made this swap in a colder spot and seen different numbers?
Check that $22 monthly savings against the $4,600 you paid up front for the heat pump, because at that rate you won't break even for over 17 years. A furnace swap would have been cheaper day one and gas prices move around a lot, so one mild winter in Boise isn't real proof of anything. That nonstop running at 14 degrees also means the unit is working way harder than a furnace ever would, and hard work tends to mean a shorter life.
