The small glue-like particles attach to holes and fill them with the substance
My partner and I noticed some areas around our apartment where the indoor temperatures seemed to be warmer or cooler than others, and the areas with temperature swings were always in the same spot. When a local heating and AC repair company offered free estimates on any repairs and upgrade works, our partner and I decided to call them to talk about the indoor temperature complications. The heating and AC repair company professional offered us a lot of advice to help with the indoor temperature complications. They suggested caulking all of the windows and buying double pane windows. They also suggested adding extra insulation to the attic, then another suggestion they made was to seal the HVAC duct. The heating and AC repair company professional found a lot of tiny holes inside of the HVAC duct. A lot of air was escaping through those holes and the result was a room with less frigid air. The holes also allow contaminants, dust, and dirt to enter the system. The HVAC duct spreads these germs all over the house. The heating and AC repair company professional suggested using a plan called Aeroseal, then it is a special sealant that gets pumped into the HVAC duct by a high pressure introduction method. The small glue-like particles attach to holes and fill them with the substance. The substance expands and creates an airnarrow Aeroseal, my partner and I thought this was a good system and we decided to have the repair performed. After three months, our energy costs are much lower and the HVAC duct is still in particularly good shape.
