An article I learn said that the average residential HVAC duct allows up to 30% of heated in addition to cooled air to leak out. The majority of ducts are improperly designed in addition to installed, including lots of sharp bends that restrict airflow through the system. They are not sealed tightly at the seams, creating gaps that sacrifice a great deal of conditioned air. Over time, small holes can develop that not only provide up heated in addition to cooled air but pull in air, fumes in addition to other contaminants from unconditioned spaces. Spending extra to purchase a high-efficiency boiler, heat pump or air conditioning system is rather pointless if the HVAC duct compromises performance, however until coming across that article, it had never occurred to me to have the air ducts professionally serviced. I am quite conscientious about replacing air filters every couple of months in addition to scheduling repair in the Springtime in addition to fall. I researched to find an Heating as well as Air Conditioning supplier that offers duct testing, cleaning in addition to sealing in my area. There was one that is certified to supply Aeroseal duct sealing, which is an innovative process that targets imperfections from inside the pipes. Because the HVAC duct is often hard-to-reach, it’s advantageous to utilize the Aeroseal process. The supplier first ran tests on airflow through the duct system in addition to verified that approximately 20% of conditioned air was escaping. He then clogged off all supply in addition to return vents in addition to pumped pressurized air into the pipes. The air contained sticky polymer particles. As the air leaked from several flaws these sticky particles adhered to the edges in addition to gradually created a narrow seal. I instantly noticed an improvement in the comfort, efficiency in addition to air quality of the home.
