Replaced oil furnace /baseboards with 2 carrier heat pumps and a Mitsubishi mini split for outbuilding cottage. The Carriers use the AC ducts which were easy but probably not optimal since they are set high in rooms where heat should be lower.

Total price for 3500 square feet was about $30k after incentives. The installers screwed some stuff up and had to return twice but when working they do just fine. We left the oil there for backup and we use it when temps go below zero. The remaining oil in our tank may last forever. The heat pumps work below zero but aren’t as efficient and basically go toward the price of resistance heating.

Overall happy and would do it again. I would have opted for removing the oil but was a little skeptical.

Depending what your house uses for power and what car/truck you use, you can often buy a 1-2kw inverter for your 12V and keep the important things going (oil heat, lights, internet, refrigerator, etc.)

You won't be able to use things like electric heat/cooking, dryer, etc but those things can usually wait for power to come back on.

You will need to idle your car while it is on, but efficiency, cost, noise and smell-wise it is far superior to buying a separate unit.

Even better if you have a hybrid or EV.
