There was no mess, no damage and no unpleasant odor
Although I knew there were problems with the duct system installed in my home, I was reluctant to hire a professional HVAC contractor for service. I figured the repairs would be extremely costly and cause a great deal of upheaval and mess. The duct system is a branching network of pipes that is concealed inside walls, ceilings and crawl spaces. To access these pipes, I assumed the technician would need to tear into the home’s structure and locate the leaks one by one. It seemed better to live with the energy losses. However, the concerns with ducts got steadily worse until about 30% of the heated and cooled air was escaping. My monthly energy bills were huge. No matter how high or low I adjusted the thermostat, the house was either freezing cold in the winter or swelteringly hot in the summer. We were living with a musty smell and abundance of air contaminants all because of the ducts. I finally gave in and hired a local HVAC company that specializes in duct repair. The technician explained the sealing process and I was amazed by the technology and simplicity. By using pressurized air laced with adhesive particles, the holes and leaks in the ducts were sealed from the inside out. First, the technician blocked off the supply and return vents. He then injected the pressurized air into the system. As the air escaped through the various flaws, the polymer adhesive particles gradually built up along the edges and created an airtight seal. There was no mess, no damage and no unpleasant odor. The process was completed in a few hours and is guaranteed for ten years.
