So my furnace draft inducer fan started making more noise recently. It was never particularly quiet, and when I moved in was making an awful scraping noise but I bent the impeller away from the casing back when I was doing some other furnace work previously and that quieted it down a bit. But that fix was not permanent, and it started making some horrible bearing grinding noises along with making the scraping noise again, so the next logical step was to replace it.
Goodbye, old crusty fan. Hello, new hotness.
So much quieter. Still not as quiet as I'd like as there's still turbulence noise from the cold air return, but it's definitely a step in the right direction.
