Like any other equipment, the duct system also has a lifespan. Over time, gaskets, seals, and insulation can weaken and malfunction. As ductwork deteriorates, comfort can be reduced and energy costs can increase. To avoid these problems, it is recommended to replace the ducts every 10 years. In most homes, ductwork lasts 10 to 15 years before issues arise.
If your ducts are more than 15 years old, it is best to change them before serious problems appear, such as pests, gaps, or even collapsed sections of ducts. This way, you can avoid drafts or congested areas and ensure that all parts of the house remain comfortable. Ducts are designed to last 10 to 15 years on average. They are made from a combination of materials such as fiberglass and plastic. We also have a variety of duct cleaning resources to learn more about residential duct systems.
You can adjust this process by installing manual dampers that can be adjusted to reduce the amount of air that enters one side of the house so that it can be diverted to another part of the house. Calling a contractor to reseal the ducts will solve the problem and, in addition, will have a positive impact on energy efficiency. Holes or holes in the ducts allow dust, pollen, and other contaminants to pass through the air filter of the HVAC system and circulate throughout the house. Twisted or tangled ductwork can also prevent the HVAC system from working properly and cause high energy bills. Mold is the worst, and if your ducts are heavily contaminated with these nasty fungi, it might be time to replace them and move on.
However, when more than 20% of the air escapes, you'll end up seeing this reflected in your energy bill. These impurities can cause obstructions that will make the heating, ventilation and air conditioning system work harder and compromise indoor air quality. Your local air conditioning installer will have specific answers about duct replacement, but here are some scenarios where that might be your best option. For example, your air conditioning unit may not be as efficient and you end up with hot or cold areas in certain rooms. Some of the most common signs that you need to replace your ducts are old ducts, high utility bills, and poor indoor air quality. Insulating the ducts not only prevents mold but also makes the heating, ventilation and air conditioning system more efficient so you'll end up spending less on your energy bill.
Especially if your house was built in the 1970s and uses asbestos insulation (a material that causes cancer), you'll need to inspect the ductwork right away. In some cases, it is not necessary to carry out a complete air conditioning duct replacement project but simply to repair one or two faulty pipes. Once the air conditioner enters a room, a fan causes it to recirculate through the air conditioning system through return ducts which are connected to larger ventilation ducts. Replacing home air ducts is an important part of maintaining a comfortable living environment while keeping energy costs low. It's essential to keep an eye out for signs that your home's ductwork needs replacing so you can take action before any major problems arise.
If you're unsure whether or not your home's air ducts need replacing, contact a professional HVAC technician for an inspection.
