    HVAC: Don’t shut your air vents to give you better heating or cooling in certain rooms/floors. You’re adding pressure to your system and reducing its life. If it’s AC then you’re turning it into a freezer. That’s why doing so freezes the coil, not enough air flow to move the cold air out and keep it from freezing. For heat it literally can overheat the control board frying it since the blower also helps cool the electronics. If you have hot and/or cold rooms (this is normal per floors) ask about adding dampers. Most of the time it’s not possible without major drywall rework and it isn’t cheap. Your builder sucks (basically). A lot of companies won’t quote the work because it can’t be guaranteed. You’re essentially stuck with the crappy design the builder got approved. One potential is minisplits. Again, not cheap per room and not pretty but they will fix your issue.

      I looked up dampers, and I’m confused about how they are functionally different than closing/opening the vent? I’m sure I’m not understanding though. Is it just about the location?

        They don’t operate differently. Also he is assuming your ducts are designed and balanced properly to begin with. Most in residential homes aren’t.

        While shutting off a lot of vents can cause problems. Shutting off an unused room isn’t going to hurt anything. Or partially closing a vent because a room gets too warm/cold. Because like I said they do fuck to balance systems in residential homes.

      HVAC: mini splits

      black mold forms and causes breathing problems. Clean aircons (air conditioner) every 6 months - 1 year.

      If water is dripping from the outside unit, your aircon is lacking gas. Making it into a giant fan.

      A mini-split is chosen to meet the needs for one room. Some folks, and can’t be convinced otherwise, think an aircon can cover the entire universe. And to prove it, they leave all the doors open.

      This is proof we live in the matrix. It’s completely unsolvable issue without self closing doors
