Your home’s central heating and air conditioning systems use ductwork to distribute conditioned air throughout the house. Leaks or poorly sealed joints in your ductwork allow that expensive conditioned air to escape into your crawlspace or attic. It doesn’t make much sense to heat and cool your crawlspace or attic —it’s expensive and very inefficient! Your home energy efficiency depends on the work of an experienced duct sealing contractor like Energeyes.
Indoor Air Quality Improves with Duct Sealing
Your Apex, NC area home’s duct system delivers the air you breathe from the furnace or air conditioner to living areas and cycles it back to be heated or cooled. If there are leaks on the return side of your system, the ducts will suck in air from the crawlspace or attic. Along with air from your attic or crawlspace, the ducts may also pick up allergens, mold, bacteria, dust mites and animal feces. Leaky ducts can affect your home’s indoor air quality and your family’s health by circulating contaminants that may be in your crawlspace or attic. A properly sealed duct system cycles the air inside your home safely and efficiently to the heating and cooling unit and back.
Finding Duct Leaks
Duct leaks are challenging to find because they can be hidden by duct insulation, but can often be located around the connections between the smaller trunk lines and the main duct system. If these connections are not sealed, they will leak conditioned air. These air leaks can be found visually or by using a duct leakage testing system during a home energy audit. Testing the duct system is important to find out how much your ducts are leaking and to document if your ducts have been sealed properly.
How is Duct Sealing Completed?
Sealing the duct system requires accessing the joints in the ducts and sealing them with mastic sealant. Despite the common remedy to fix everything, duct tape is not the best way to seal ductwork as it does not perform well long-term. The best way to seal the joints is with a duct mastic which creates a strong, durable seal on the joints.
