How to seal ductwork without professional help
Contrary to belief, you can actually seal your air ducts without professional help.
My boyfriend who is an air conditioning technician would probably drop kick me if he knew I was saying this, but I’ve seen him seal ducts so many times that I could probably do it in my sleep.
The first thing you want to do is run the air conditioner and inspect the air ducts to find where the leaks are. To find a thermal leak you can run your hands along the duct, or you could listen for air pressure and perhaps whistling noises. Once you find the leak, hold the air duct in place and apply a sealant mask over it. It will take the sealant various times to dry, and that will depend on the type of sealant you get. Once it dries, the leak should be sealed and you shouldn’t have much problems with the air duct anymore. Maybe I am oversimplifying the process, but this is exactly what my boyfriend does whenever I see him repair air ducts. Some people think it’s weird that I accompany my boyfriend to work, but I have a really flexible job and I miss him so much that I don’t mind doing it. I’ve learned a lot about what he does too. I’m able to work in the car by using my hotspot for my computer, so we both work while we get to spend a little bit of time together. Because I have a child and we don’t live together, it can be tough to see each other outside of work sometimes.
