My gas furnace and cooling system are less than multiple years old.
I take truly great care of them, making a point to change air filters every month and to schedule professional upkeep every Springtime and fall.
Because of this, I was surprised when I had some complaints about the performance of the heating plan last winter. There was entirely less heated air coming from the vents. I was forced to adjust the control component several degrees higher and yet particular rooms were always frosty. I always realized that there was quite a bit of dust and other debris floating around in the air and accumulating on surfaces. A musty aroma coming from the supply vents caused myself and others headaches in the days. When I noted that the gas furnace was running always, I called our correct Heating and A/C corporation for repairs. The worker first tested all components of the gas furnace and found no issues. She then diagnosed the air duct and discovered small holes and leaks at the seams. She estimated that 25% of the heated air was escaping through these flaws. This was forcing the gas furnace to run longer, work harder and use more energy. These imperfections were drawing in unfiltered outdoor air and spreading it to every room in the house. I was concerned about how the worker planned to repair the problem. The ducts are concealed inside the walls and ceilings and impossible to access. The corporation utilized a process called Aeroseal that sends highly pressurized air laced with polymer particles into the ducts. The sticky particles adhere to the edges of the seams and holes as the air leaks out, gradually creating a slender seal. The whole process was completed in a couple of hours and totally solved all the issues with the gas furnace.
