Got Mitsubishi minisplits at our place last year which I found out no longer qualify for the rebate. Put a Bosch system in to replace an old AC ducted system literally yesterday at our rental and made damn sure the AHRI is on the qualified list this time.

Def nice to have a nat gas boiler on extremely cold days. The efficiency of even the best HP today drops significantly the colder it gets. I’d go IBC combi if you need both a water heater and gas boiler. We have oil heat and I plan on removing the tank and boiler down the road or converting to wood pellets.

I believe in 2023 you can get 750 back for a heat pump water heater as well which can also help control humidity in a basement.

If I do heat pump I would do propane as a backup hest as I will need hot water as well, probably a tankless hot water heater or maybe one of those hybrids water heaters

Yep, my neighbor has propane as a backup and seems to work for his solar + heat pump setup. I would check out heat pump water heater if you can get 750 off

Unfortunately municipal electric so no mass save rebates
