Tploy to her assumption, this is precisely what was happening
Having owned an Heating, Ventilation as well as A/C plan for five years, I never experienced the peculiar sounds that were suddenly coming out of the heating and cooling unit, however i came house from work one evening to be greeted by loud banging, but at first, I was scared and even took a back step to rethink whether I wanted to get inside the house. I kept wondering if someone had broken into the house without our knowledge, so I evaluated the alarm plan and all the windows and alternative home offices. I only opened the door when everything evaluated out, however I was still careful to get in. I walked in, past the home office, and carefully matched to the kitchen to get a knife just in case. The closer I got to the kitchen, the louder the bang. Finally, it dawned on me that this could be a burglar since they would want to be quiet so as not to arouse any suspicion. Now that I was a bit calmer, I surveyed him around and walked towards the backdoor when I noticed that the sound was coming from the AC unit. For some reason, the banging sounds happened to be coming from the air conditioning system. I called the Heating, Ventilation as well as A/C business, who commanded me to switch the component off, check for debris that could be cottaged inside, and consider any hanging components. Tploy to her assumption, this is precisely what was happening. I also got to learn the weird AC noises that have weird meanings. Homeowners need to understand what each of these sounds represents, especially when the sounds are persistent, however rattling, bubbling, dripping, and whistling sounds all have varied meanings and should not be ignored.
