Duct sealing resolves issues with bugs and dust

Last July, the weather got extremely hot and humid. The outside temperature was steadily in the upper eighties and low nineties, and the air conditioner was running constantly. I started to notice that the cooling system was having some trouble keeping the house at a comfortable temperature. Certain rooms felt a bit hot and sticky and adjusting the thermostat didn’t make much difference. I then realized that there was more dust blowing around and settling on surfaces than usual, and even a faint musty smell in the air. Assuming there was a problem with the air conditioner, I set up an appointment for repairs from a local HVAC contractor. They were extremely busy and I was forced to wait until the following week. For the next seven days, my house was overrun with flies. I chased them with fly spray, killed them with the flyswatter and sucked them up with the vacuum cleaner. I found them crawling on my windows and ceilings, and flying around in every room. It was absolutely horrible and I couldn’t figure out where they were coming from. When the HVAC contractor showed up, I told him about the flies. He completed a thorough inspection of the cooling system and found leaks in the seams as well as holes in the duct system. He said that the defects in the ducts were the cause of all my complaints with comfort, dust and bugs. I had to schedule a separate appointment for duct sealing, and by then, I was going out of my mind. Fortunately, the duct sealing process fixed everything. After that, there was no more flies and the air conditioner was able to keep a nice cool and even temperature.
