Very true, Jay. I definitely wouldn't do anything without consulting a Peterborough building code inspector.

I had a look today, and I noticed a couple things. While I was watching a movie that I had playing quite loud, I could easily here by HVAC system. My HRV is quiet, but the HEPA is quite loud, and my furnace only makes things louder when the heat comes on. I honestly think the only option is to box the back of the cabinet up, rather than leaving it open.

The other thing is that there is an available outlet, but it's not a dedicated one, and I don't know what else is on that circuit. I'm wondering if it's possible to just replace the current fuse with a larger one to accommodate for my electronics? Wouldn't it be the same as having a dedicated 20 amp circuit?

The only reasonable argument for owning a gun is to protect yourself from the police.
