I started hearing a strange noise when the HVAC unit would come on

Every time the HVAC started running, I would hear an odd noise.

  • It sounded like tiny balls rolling on a surface, especially if one was in the sunroom.

I searched the entire house but could not find where the noise originated. I eventually gave up as well as called for house services, the first thing was for the HVAC professional to find out if the noise was indeed in the conduits, as I suspected, and also to upgrade to a smart HVAC system. When she came, she said that the best cause of action was to do a duct cleaning because then we could remove everything in the ducts, after inspecting the HVAC equipment, she said all needed for the upgrade was repair as well as a smart thermostat. The rest, such as the smart vent, could follow later on since I was on a limited budget. That was a relief because I thought I would have to replace the entire plan or the better part, but she also showed me all the dirt as well as dust that the air filter had trapped and told me to increase the frequency at which I replaced it. She also encouraged me to buy a whole-house air purification plan since the air purification help in the HVAC was not enough to maintain the indoor air pollen levels. The air purification plan would ensure that the air quality in the house was high. When the HVAC professional finished with all matters concerning air purification in my home, we finally found out what was causing the odd noise. After the cleaning, she discovered numerous marbles in the conduit leading to the sunroom. I had no idea when or how the marbles ended up in the duct, but I was glad to be rid of the noise as well as the dirt.
