The buildup was blocking airflow, forcing the furnace to work longer and harder… Plus, every time the furnace started up, it was spreading contaminants into the indoor air.
I couldn’t figure out why our loft was abruptly so dusty, then despite constant cleaning and vacuuming, there was constantly a film of dust buildup on surfaces, and my youngsters were frequently sneezing, coughing and complaining of sore throats. I worked on the air filter of the furnace, however it wasn’t clogged or dirty. I then realized that the furnace was running far more often than usual. I noticed cold spots in multiple rooms and a slight musty stink in the house, then assuming there was some concern with the operation of the furnace, I called a local Heating, Ventilation, and A/C business for repair, then the professional worked on the inner workings of the furnace and found no problems. The then worked on out the duct system and discovered a significant accumulation of debris. He asked when I’d last had the ducts professionally cleaned. I hated to admit that I’d never even considered the condition of the ductwork, and since buying the house more than nine years before, I’d never done anything with the ducts, but our multiple remodeling projects caused a lot of dust and debris, which settled inside the ducts. The buildup was blocking airflow, forcing the furnace to work longer and harder… Plus, every time the furnace started up, it was spreading contaminants into the indoor air. The Heating, Ventilation, and A/C business performed a complete duct cleaning. He used component that looked a lot like a big vacuum cleaner to dislodge and suck the pollutants out of the system. The whole process only took a couple of hours and caused no mess or damage! While the duct cleaning service was fairly pricey, it was legitimately worth the investment.
