My furnace plus cooling system are less than many years old.
I take genuinely nice care of them, making a point to change air filters every month plus to schedule professional upkeep every Spring plus fall.
Because of this, I was surprised when I had some complaints about the performance of the heating program last winter. There was particularly less heated air coming from the vents. I was forced to adjust the control device many degrees higher plus yet particular rooms were regularly cold. I always realized that there was quite a bit of dust plus other debris floating around in the air plus accumulating on surfaces. A musty odor coming from the supply vents caused myself and others headaches in the afternoons. When I noted that the furnace was running consistently, I called our proper Heating, Ventilation and A/C company for repairs. The professional first checked all components of the furnace plus found no troubles. He then diagnosed the ductwork plus discovered small holes plus leaks at the seams. He estimated that 25% of the heated air was escaping through these flaws. This was forcing the furnace to run longer, toil harder plus use more energy. These imperfections were drawing in unfiltered outdoor air plus spreading it to every room in the house. I was concerned about how the professional planned to repair the problem. The ducts are concealed inside the walls plus ceilings plus impossible to access. The company 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 plus holes as the air leaks out, gradually creating a narrow seal. The whole process was completed in a couple of hours plus totally solved all the troubles with the furnace.
