Every time the heating and air conditioning started running, I would hear a weird noise, it sounded like tiny balls rolling on a surface, especially if one was in the sunroom.
I searched the entire house but couldn’t find where the noise originated.
I eventually gave up and called for new home services. The first thing was for the heating and air conditioning professional to find out if the noise was indeed in the conduits, as I suspected, and also to upgrade to a smart heating and air conditioning 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 heating and air conditioning equipment, she said all needed for the upgrade was repair and a smart temperature control. 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 update the entire plan or the better part, and she also showed me all the dirt and dust that the air filter had trapped and told me to increase the frequency at which I updated it. She also encouraged me to buy a whole-home air purification plan since the air purification help in the heating and air conditioning 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 heating and air conditioning serviceman finished with all matters concerning air purification in my home, we finally found out what was causing the weird noise. After the cleaning, she discovered three marbles in the conduit leading to the sunroom. I had no idea when or how the marbles ended up in the duct, although I was ecstatic to be rid of the noise and the dirt.
