A central-air system pumps heat into all of the rooms of your house. This is an efficient way to heat a home if all of the rooms in the home are in use. While ducts are important in piping heat to the different rooms of your house, they can also lead to a loss of efficiency for those who don't maintain them. Those who maintain their ducts properly will achieve greater efficiency as well as prolong the life of their furnace.
Sealing Leaks in Ducts
The pressure of the air running through ducts can put stress on the joints and seams in the ductwork. This stress can cause the seams to fail, and when they do, the heated air from your furnace can leak out of your ducts before it reaches your home. In fact, ducts can reduce your furnace efficiency by up to 40%. If you notice that your heating bills have been increasing without a corresponding increase in the price of fuel for your furnace, the culprit might be a leak in your ducts. If your ducts are encased behind the drywall in your home, you will have to hire professionals to inspect your ducts and repair any leaks they find.
Insulating Your Ducts
If you have ducts that run through an attic or through an uninsulated basement, the ducts can be chilled by outside air. Once the ducts are chilled, they can chill the air running through the ducts. Chilled air will take longer to heat your home than the hot air escaping from your furnace. In order to protect the efficiency of your furnace system, you need to insulate your ducts. If you are handy with tools, you can cut fiberglass insulation to fit your ducts and wrap them around your ductwork. On the other hand, if you don't think you have the skills to insulate your ducts on your own, you can hire a professional like Borter Heating & Air Conditioning Co to insulate your ducts for you.
Trying to improve the function of your ductwork will also improve the efficiency of your HVAC system. The improved efficiency of your ductwork will make it so that your furnace does not have to run as long or as hard to keep your home warm. While a lot of people focus on their furnace when it comes to improving the performance of their HVAC system, it is important not to overlook your ductwork.
