Yeah that's totally valid. Agreed.

But I also wouldn't really trust third party parts for the appliance itself. I think once you do, that immediately becomes a possible problem. If it was in my house, I'd only buy from the manufacturer for something like that.

But on the other hand, Idk that it's necessarily wrong to legislate forcing these companies to allow it. I generally believe consumers should have the option on their own, but some things are too dangerous. I'd pretty much be against medical devices but HVAC is a little more uncertain to me.
