Can I pester you with a question? Feel free to tell me to get bent because I know your time is worth money and this is just the internet. We have a new Trane system that was flawless when it was first put in, but over the past five months the blower has started making louder and louder vibration noises. Almost like it’s slightly off balance. If it was an older system I wouldn’t think twice, but it was dead quiet at first, just the sound of moving air pretty much.
Part of me wants to open up the cabinet and just see if there’s some sort of vibration pad that’s gotten loose, but I also don’t want to to void a warranty, or something. It seems so trivial a thing. We live in the boonies and a service call is pretty onerous for a tech. I thought maybe there could be balancing weights, like a car wheel or a lawnmower blade, but your comment about motors being sealed is making me think twice.
Thank you. It’s a new construction and the builder seems to generally pick really good subs, and I’m pretty sure whoever installed it did the entire house, so they should be familiar with it. I’ll give them a call.
