Resealing air ducts is super important to maintain the quality of your central HVAC.
If you don’t seal your ducts as needed, air can leak and condensation can be created which can damage your walls.
It’s better to be ahead of the game when it comes to your air ducts so that the issue doesn’t get worse than it needs to be. Sealing your air ducts doesn’t have to be expensive either! I think many people are under the impression that this type of repair costs a lot of money, but it’s something you could technically do on your own if you understand how the air duct system works. Lots of people seal their own air ducts and then have a technician come to do a larger seal once every couple of years. If you’ve never done it before, I’d recommend watching lots of videos and perhaps even have a professional come do it so that you can watch and learn from it. If you pay attention and take it seriously, you could seal your own air ducts and save yourself some money. I don’t always recommend doing repairs on your own though. Some work really does require professional help. People don’t go to school to learn these things for no reason. My dad went to school to become a firefighter so that he can learn to professionally put out fires. Maybe that’s not the best example, but my point is that people are trained to do things that the average person may not have the knowledge or resources to handle.
