Hey all. I had boomba install my bov about 5 months ago. I live in the chicago area and on one of the sub zero days my bov stopped making noise. It came back once or twice since then but not consistently. It still seems to purge when I let off the gas but I'm not sure if there is any concern. I'll probably end up taking it to them this week since they are like ~15 minutes away just wanted to know about the safety of it. Thanks.
