Short answer is yes.

I got curious and dug up the spec sheet. budgetheating.com/…/BOVA36-60HDN1-M20G Technical … So I overstated my particular unit. It’s rated to -4F.

I live in a climate that gets under -4F a few times a year, so I also have an auxiliary furnace. I set the cutover temp very conservatively at 20F for last winter as it was the first winter using the heat pump, and I also heard people telling horror stories about $1000 electric bills in January.

While my winter electric bill is now larger than my summer bill, the increase in electricity spending is about half the decrease in gas spending. Looking back at the temperature record, my furnace turned on about 10 days last winter.

I’ve got the cutover set to 0F this year and we’ll see how that impacts the balance.

It’s also worth noting that my home was built in the early 70s and still has the original windows and insulation, so it’s a long way from the ideal case.

As for your experience with HVAC technicians, I also met a few who clearly still thought heat pumps didn’t work well enough, and others who basically recommended them to everyone. It really seemed to be a generational thing.
