If your HVAC system is not as efficient as it used to be, the problem may lie in your ductwork. Problems in the ducts can affect your energy costs, air quality and consistency of your heating and air conditioning. If your heating and air conditioning units are working properly but you are still losing energy, look for these signs that your ductwork needs to be replaced.
1. If your ducts are over 10 years old and the joints or seams are deteriorating, you may need to replace them. Just like the rest of your HVAC system, you ducts need to be maintained. Even with diligent maintenance, though, your ductwork will not last forever.
2. Inconsistency in the air flow between different rooms in your home can indicate a problem with your ductwork. If there is a blockage or a leak in your ductwork, the air flow may not be consistent in all of your rooms. Check for variations in temperature as well as the speed of the air coming through the vents in each room.
3. Because most of your ductwork is hidden, the best way to determine if you have a problem is to make an appointment with your HVAC contractor to perform a blower test in your home. The blower test takes about an hour and will tell your contractor how much air you are losing through your ductwork. If your blower test shows that you are losing a significant amount of air through your ducts, it may be time to replace them.
