Cold climate heat pump
Anyone have any luck with the MrCool inverters? Something to replace a ducted gas furnace? https://mrcool.com/mrcool-dc-inverter-heat-pump-air-conditioner-split-condenser/
Cape cod style in Spokane, WA. Existing gas furnace <80% efficiency (I believe late 80’s). No AC. Around 1600 sq/ft with some improvements. Basement is R25, rigid insulation, new windows, etc. Current furnace ramps up, then cycles a lot. Single speed. Utility costs aren’t wild. Hydro electric and nat gas are cheap compared to some rates I have seen.
Did a Mr Cool minisplit with a neighbor in a 800sqft garage (remodeled into an art studio with some insulation, drywall, etc) and it worked great. Super easy and seems to work just fine year round.
Big one is getting some AC in the house to lower the temp a bit in the heat of summer. We drag out the window shakers and scrape up the old window ledges and do that whole thing every year, never look forward to it.
Alternatively looking at the VRV dual fuel setups from Daikin, but that excludes me doing it myself.
Putting in the MrCool doesn’t look too daunting. I have prepped a sleeve for the lines, added power, pad, etc some time ago during the basement remodel.
Big fear is running into 0/5 degree overnights (recently) and then getting hit with a huge electric bill, where the gas would have kept up otherwise.
