There very well may not be a problem at all, but I personally wasn't comfortable taking a "non-problem" to be just what it is until I was sure. For me, it was buying my temp gun and my thermostats, so those are my suggestions. A lot of people might come off as bossy like you said, but they are mostly all just suggestions that may be that peace of mind the OP needs, even if it means trashing whatever upgrade they just got and spending a little more money.
