Then the same concerns showed up again
I learned the hard way the duct tape doesn’t actually work to repair holes in the air duct system. Last summer, I noticed that the air conditioner was struggling to keep up with demand. Lowering the thermostat setting simply caused the unit to run for longer cycles. It just wasn’t putting out enough cool air to maintain a comfortable indoor temperature. I also realized that certain rooms in the house were cooler than others. I looked up these problems online and found that the issues were most likely caused by leaks in the ducts. Because the ductwork in my house is concealed inside the crawlspace, accessing the pipes is difficult and horrible. I got my flashlight, crawled into that tight space and inspected the ducts. I saw that there were definite leaks where the seal along the seams had dried out and cracked. I could feel the cool air pouring out of these spots. While my house was rather overheated, the crawlspace was downright chilly. I assumed that I could repair the seams with duct tape. I am not sure why it’s called duct tape when it is worthless for the job. I spent over four hours wedged into a tight space, carefully fitting the duct tape around every seam that I could access. For a couple of days, the problems were solved. The house was a pleasant and even temperature. The air conditioner wasn’t running for such long cycles and I looked forward to lower energy bills. Then the same concerns showed up again. I went back into the crawlspace and discovered that all of the tape had peeled off.
