Ductwork for Furnaces are the veins of a house. Many different methods can be used to heat a home, including boilers, water heaters, and wood-burning stoves. Still, the majority of American homes are heated by a forced-air furnace. Since the cost of heating a home is always on the rise, it is in a homeowner’s best interest to gauge and improve the furnace’s efficiency. And when it comes to efficiency, residential furnaces in the U.S. are defined by two main categories: medium-efficiency furnaces and high-efficiency furnaces.
A huge component of a furnace’s efficiency is its ductwork. Ductwork connects the furnace to the registers throughout the entire house –they are conduits used for heating, ventilation and air conditioning. The ductwork moves supply air, return air, exhaust air and ventilation air throughout the residence. The amount of supply and return ductwork a furnace has impacts the efficiency of the unit.
On an average, ductwork maintains its structural integrity, lasting for as long as 10-15 years before it starts to deteriorate. Once it begins to degrade, it will lead to ineffective heating and cooling. This will prevent the house from being as hot or cold as desired, an increase in energy bills, and poor indoor air quality.
If you’re already experiencing these symptoms of worn out ductwork for furnaces, or if you are installing new ductwork proactively, Furnace & Duct is prepared and prompt with providing the necessary supplies.
