5 Signs You Need to Repair or Replace Your Ducts

If you think your ducts need to be repaired or replaced, there are a few tell-tale signs you should look out for. Firstly, inspect the ducts for any holes, crushed ducts, or missing ducts. Turn on the air conditioning system and see if you can spot any air moving where it shouldn't be. If your ducts are more than 20 years old, it is recommended to schedule an appointment with a local HVAC contractor to reevaluate your system.

Most likely, the entire system will need to be replaced. Any strange sound coming from the ducts is a sign that they need repair or thorough cleaning. Additionally, if your ducts are very dirty, the first thing you should do is schedule a duct cleaning. Air ducts are an essential component of your air conditioning system and their need for maintenance or repair should not be overlooked. According to Energy Star, 20 to 30% of the air that circulates through the duct system is lost due to leaks, holes, or poorly connected ducts.

While loft-style spaces and some contemporary home designs leave ducts exposed, most homeowners live in buildings with ducts that are cleverly hidden in attics, ceiling lights, and cramped spaces. If you start to see, hear, or smell any of these signs that you need duct repair, the best way to fix the problem is to contact a professional HVAC technician to have the ducts inspected. Remember that your air conditioning system is complex and that any repair or maintenance must be carried out by a professional to avoid damage or higher repair costs. Whether it's repairing existing ducts or completely replacing them, it is important to contact a professional HVAC technician for assistance. Here are five main signs that the air ducts in your home need attention:

  • Holes, crushed ducts, or missing ducts
  • Strange sounds coming from the ducts
  • Very dirty air ducts
  • Air moving where it shouldn't be
  • Ducts more than 20 years old
Rather than saying that your home needs X feet of Y-sized ducts based on their square feet, HVAC technicians use a software program that incorporates several factors to determine the size, length, and design of ducts to optimize comfort and efficiency.

The best thing to do in this case is to call a professional to check the ducts and determine if they need to be repaired or replaced.
