  • From a person with a lot of years of experience fighting mold on wood in a humid climate, what you want is borax:

    Borax kills mold and also soaks into wood and stays there to prevent future growth. Bleach does not help on porous surfaces like wood:

    "Note that bleach should not be used to kill mold found on wood. While bleach is very effective for killing mold on non-porous surfaces, it doesn’t work well when it comes to wood. This is because the chlorine in bleach can’t penetrate wood, so only the water portion of the bleach gets absorbed.

    The mold may appear to be removed from the surface, but it’ll likely continue to grow underneath and return within a few months."









  • Yes, Massachusetts. I have a dual fuel heat pump with natural gas backup installed in 2020, so it’s a newer system. And I have one heat pump mini split in the least energy efficient, but most used room in my house (large, high ceilings, exterior walls on three sides, and a skylight).

    The first couple of years I noticed when it got just below freezing, the central heat pump seemed to struggle to keep up. Then this year I replaced my windows and got new wall insulation in both of the main bedrooms and bathrooms (previous insulation was original from the 1960s and shredded to bits with huge gaps.)

    After those improvements, I’ve been running my heat pump down to 20⁰F/-7⁰C so far without any issues at all. I’m excited to see how cold we can get and this system still keep up. I am still supplementing my one large room with the mini split, but that’s mostly because all my plants are in here, so I keep this room warmer than 68⁰F/20⁰C.
