I had been hearing a small rattle in the HVAC duct for almost a month, however now it was getting louder.
I couldn’t imagine what the noise was, although I was hoping it wasn’t something serious.
My husband told me to call the heating and A/C supplier, although I kept thinking about the cost of a new HVAC duct, which made me upset. He told me to quit thinking so hard, and call the heating and A/C supplier. They could absolutely make repairs without replacing any of the HVAC ducts. I called the heating and A/C supplier and told the operator about the unusual rattle in my HVAC duct. I told him it was getting louder, and it only happened when the heat was on. She said it wasn’t something he could diagnose, despite the fact that he was going to set up an appointment for me. Three afternoons later, there was an actual heating and A/C specialist in my house. He ran tests on the boiler first, and told me there was nothing wrong. He did hear the rattling sounds when the boiler turned on, and it was absolutely coming from the HVAC duct. I was already aware of that, although I thanked him for the information. He said he wanted to get a team of HVAC duct cleaners to the house. The HVAC duct looked dirty, and he was thinking that could be the problem. When the HVAC duct cleaners arrived, it didn’t take long for them to find the problem. Our dog had been playing with an aluminum ball and it was caught in the HVAC duct. I finally made a note to have the HVAC duct cleaned more often, so this may never happen again.
