Yup, it was definitely in the price range. We haven't gotten our next bill yet so it's unclear how much of a difference it makes, but the apartment feels less drafty after the fact so anticipating it will make a difference

Hey-oh - fellow Morgan resident here! We literally just had the same thing happen to us. This was the second winter in a row so we were pretty sure something must have been screwy with our insulation, having done the whole meter song and dance last year to no avail. We had the maintenance guys take a look this year. As it turns out, those floor to ceiling windows? Really difficult to close so you're almost guaranteed a draft. (The two maintenance guys who looked like strong dudes even had trouble closing them - it was a team effort.) I'd have maintenance roll through to see if that's an issue for you too and that might make a difference.
