Derek Cole says unfamiliar sounds from your HVAC unit mean something is wrong. Don't ignore them. Call a professional to diagnose the problem before it gets worse.
If your unit is making a sound you've never heard before, you need to call a professional. Something that's out of the ordinary, something you're not used to hearing, could be an underlying problem.
