For quite a few years, I ignored the upkeep up the ductwork.
It never occurred to me to have the system serviced.
I am conscientious about replacing air filters in the furnace and air conditioner. I make sure to schedule annual tune-ups for the heating and cooling units. None of the contractors who handled the job mentioned the ductwork. This network of pipes is essential to both heating and cooling. The air my family breathes travels through them multiple times per day just about year round. Any contaminants that are concealed inside the ducts can easily become airborne during operation and spread to every room in the house. The buildup of debris also restricts airflow, making it more difficult for the furnace and air conditioner to achieve and maintain the thermostat setting. When the units are required to run longer, they use more energy and experience greater wear and tear. My utility bills and the chance of a malfunction increase. Some of the harmful toxins that are often found inside ductwork include dust, dander, decomposing pests, rodent feces, bugs, construction materials and mold growth. Coughing, sneezing, congestion, headaches, insomnia and even nausea can be blamed on dirty ducts. I am now conscientious about scheduling professional ductwork inspection every year. If necessary, the contractor handles cleaning and/or sealing of the system. The cleaning process takes a couple of hours but causes no mess or damage. I immediately notice a difference in the cleanliness and comfort of the home. The air flowing from the vents smells better. Hopefully, by taking better care of the duct system, I can expect greater value and longevity from the entire heating and cooling system.
