HVAC efficiency studies show that anywhere from 10% - 30% of cool and heated air is completely wasted due to ductwork leakage, so whether you’re a business owner, contractor or homeowner, making sure that your HVAC system is functioning at its best is extremely important. Every bit of air that escapes your space is literally money wasted and many utility companies now offer rebates for the sealing up ductwork for residential properties and even have special incentives for small businesses. Check with your local utility company for more information as to the specifics of these incentives and availability. The importance of having your “Ducts” In a Row Ductwork is typically located in areas you couldn’t care less about conditioning such as the attic, crawl spaces, the basement, and the garage. Recent studies show that an anywhere from 10% - 30% of an average units output is wasted due to duct leakage and that sealing up your duct work can cut this waste to less than 5% if done correctly. Improperly sealed ductwork can have a direct affect on your health. Not only is duct leakage an enormous waste of energy, but it also allows for unconditioned, dirty air to be pulled back in causing a whole host of problems you might have never thought of. Aside from hindering your HVAC systems ability to heat and cool, this air can introduce dangerous dusts, molds, microbes and even radon gas into your space. This is such case that the U.S. Environmental Protection Agency attributes ductwork leakage as a measurable contributor to lung cancer and respiratory illnesses.

Since your HVAC system can only be as efficient as the ducting used to supply it, we need to have the right tools to fix the cause(s) of duct leakage. The first places to check for leaks include the supply and return plenums, starting collars, fittings in the duct runs, splices and terminations where the ducts connect to the supply registers. The fix can be as simple as retaping your ducting or a replacement of connecting components and the ductwork itself. Duct Tape/Sealant - Not always created equal One of the tools for sealing up duct work as we mentioned above, is the all important duct tape. We’re certainly not talking about ordinary household duct tape here. For our purposes we need something special, a UL 181 rated tape. We have just the ticket with our FOIL-GRIP 1402 181BFX, butyl-backed duct-sealing tape providing an instant grip to most surfaces including sheet metal, duct board, flex duct, PVC coated duct and duct-wrapped vapor barriers. It’s extra sticky and it’s the best tape we’ve been able to find. Using the proper form of duct tape is the only way to properly seal up joint components and other areas that duct leakage is prone to occur.
