I also didn’t understand for a long time what exactly this service includes. When I first saw its name, I asked myself: what is furnace cleaning and https://comfortclean.com/furnace-duct-cleaning-what-is-it/ , do I need it? It turned out that this is a comprehensive cleaning of the air duct and ventilation system, which removes dust, mold, animal hair and other allergens that have accumulated over the years. This not only improves the air quality in the house, but also helps the heating system work without overload, reducing energy costs.
