How Often Should You Seal Your Home's Air Ducts?

Even if you don't detect any obvious signs of damage to your home's ducts, it is still recommended that you have a professional conduct a duct test. The lifespan of an air duct sealant is determined by a variety of factors, such as the age of the air conditioning system, the climate, the efficiency of the appliances that rely on the air conditioning system, how often the filters are changed, and the maintenance of the rest of the system. At Sealed, we rarely suggest duct sealing alone, as sealing air throughout the house is essential for overall energy efficiency and comfort. As certified Aeroseal air duct technicians, DuctMedic is qualified to execute a program created by the Environmental Protection Agency (EPA) called “Duct Investor”. This program takes into account a variety of variables and provides the owner with an estimate of what they should expect in terms of cost savings.

After the sealing process is complete, a post-sealing test will be conducted to ensure that all leaks have been properly sealed and that the ducts are now airtight. If your home qualifies, you may be able to get a full home air sealing package (including improvements to duct sealing and insulation) without paying anything up front. Sealing air duct leaks can prevent up to 30% of energy loss, improve the efficiency of your heating and cooling system, and significantly reduce your energy bills. It can also reduce temperature inconsistencies and drafty areas, providing more uniform heating and cooling throughout the house. To check for leaks, use a smoky pencil (or an incense stick) and slowly pass it along any visible conduit.

As mentioned earlier, an average home can lose 20 to 30% of its air conditioning due to air duct leaks, some of which are invisible to the naked eye. If you notice any signs that your air ducts are not working properly, a Filterbuy LOCAL professional will be happy to examine your situation and give you professional and honest advice. Diagnostic measurement provides a scientifically valid means of understanding the performance of your air duct system. The dry sealing material mainly contains two chemicals: vinyl acetate polymer (VAP) and 2-ethyl-1 hexanol (2E1H). You can trust Atlantic Bay Contracting to be a reliable and experienced provider for your duct sealing needs. The Aeroseal air duct sealing system can reduce the amount of leaks by up to 90%, reducing dust and other indoor air pollutants from your home air conditioner.

According to ENERGY STAR, if you properly seal your air ducts, you could reduce your home's energy consumption by up to 20%. Air conditioning systems heat and cool a building by directing air through ducts to rooms that require temperature control. Filterbuy and the United States Department of Energy recommend leaving the ducts in the hands of professional sealants. It is important to understand that sealing your home's ducts is not something that should be done on a regular basis. The frequency with which you should seal your home's ducts depends on several factors such as age, climate, efficiency of appliances, filter changes, and maintenance.

However, it is generally recommended that you have your home's ducts tested at least once every two years in order to ensure that they are functioning properly. Doing so will help you save money on energy bills while also improving comfort levels in your home.
