I need to get a HVAC professional to look at the HVAC system

For the past few evenings I’ve been waking up in the middle of the night and hearing the most spine-chilling noise, it sounds like metal is grinding and it’s coming from my HVAC closet. I have 2 small children and they are being tortured by this noise in the middle of the night and have not been able to get a good evening’s sleep in what feels like weeks. I had a feeling that this noise was my HVAC plan letting me know there was an issue. I knew I needed to call a local HVAC business and have them come out to my home and service my heating and cooling plan instantaneously because this noise was a sign something is actually wrong. So I made an appointment with the local HVAC business to see if they could come out and help me figure out what was going on with my HVAC system. I can’t continue this noise in the middle of the evening because my children are starting to have nightmares. I don’t want them to have issues moving forward sleeping so I need to make sure to get my HVAC plan under control. I hope that the HVAC complications aren’t expensive and then I am able to get them straightened up pretty abruptly because not only do I want to have a good night sleep but my kids also need to have a good night sleep if they are going to focus on school every day.
