Ducts can become brittle and corrode over time, reducing their effectiveness and efficiency. In addition, if any ducts have been damaged or modified since the original installation, they may need to be replaced to maintain optimal performance of the new system. Most air conditioning systems last 10 to 15 years before needing a replacement. However, modern air conditioners often require newer ducts to work properly. Old ducts will impede the performance of the air conditioning unit if they are not compatible with the operating requirements of the air conditioner.
Like any other equipment, the duct system also ages. Over time, gaskets, seals, and insulation can weaken and malfunction. As the ductwork deteriorates, it can decrease comfort and increase energy costs. To avoid these issues, it is recommended to replace your ducts every 10 years. This way, you will ensure that the air ducts remain in good condition to provide high indoor air quality.
If you detect a foul odor in the air ducts, contact a heating and cooling specialist to inspect them and replace the ducts if necessary. If you notice signs of pest infestation, you need professional help to get rid of the pests and replace the ducts. Residential ducts often have twice the lifespan of traditional air conditioners and require replacement every 30 years. Your HVAC specialist will evaluate your ductwork and determine if you need to install a new duct system after replacing the air conditioning unit. If the ducts are already damaged and are at risk of attracting insects, you should consider replacing them.
Like all HVAC equipment, air ducts wear out, so it's important to have them checked and possibly replaced every 10 years or so. Many HVAC technicians recommend installing new ductwork after replacing the air conditioner to ensure optimal efficiency and even air distribution. Depending on the extent of the damage, the professional will decide if it is necessary to repair or completely replace the ducts to resolve the problem. Installing new ductwork every time you replace your air conditioner is a safe way to guarantee optimal operation and exceptional indoor air quality. If you observe a sudden increase in your monthly energy costs, hire a professional to inspect your ducts and determine if they need to be replaced. Replacing old ducts before they suffer significant damage will prevent you from wasting money on unnecessary repairs.
If the ductwork makes strange noises as air flows through it, it may need repair or even a complete replacement. A trained HVAC technician will determine if you would benefit more from a complete repair or replacement of air ducts and will provide advice based on their expertise.
