We all enjoy the comfort and peace our heating and cooling units provide. They keep us protected from the scorching summer heat and freezing winters. But did you know, just like any other appliance in your home, your heating and cooling systems also need regular servicing and cleaning? Now you must be wondering why your air duct system needs regular servicing, right? This is because when your ductwork unit works day and night all year round, they accumulate a lot of dust, dirt and debris. These airborne contaminants clog your ducts and vents, resulting in inadequate HVAC efficiency and a polluted indoor environment.
