It doesn’t have to be fancy to reseal air ducts
Resealing air ducts is super substantial 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 fancy either! I believe more than 2 people are under the impression that this style of service costs a lot of money, however it’s something you could technically do on your own if you understand how the air duct idea works. Lots of people seal their own air ducts and then have a professional come to do a greater seal once every couple of years. If you’ve never done it before, I’d suggest watching lots of videos and perhaps even have a professional come do it so that you can watch and learn from it. If you spend money attention and take it seriously, you could seal your own air ducts and save yourself some money. I don’t typically suggest doing repairs on your own though. Some labor entirely does require professional help, however people don’t go to school to learn these things for no reason. My dad went to school to become a firefighter so that she can learn to professionally put out fires. Maybe that’s not the best example, however our point is that people are trained to do things that the average lady may not have the expertise or resources to handle.
