Can You Seal Air Ducts Yourself? A Comprehensive Guide

Some homeowners opt for duct sealing as a DIY project. To start, seal air leaks with putty or metal tape and insulate any ducts you can access (such as those in attics, mezzanines, unfinished basements and garages). Never use adhesive tape, as it is not durable. We recommend using a putty sealer for sealing air ducts. Adhesive tape is not a good choice, as it quickly starts to come off.

If you prefer to use adhesive tape instead of putty, look for aluminum foil tape specifically designed for HVAC. If you need more information on duct sealing for your home or business, contact the professionals at Service Champions.Most homeowners don't think about sealing their home's air ducts, but the process is essential to maintain the energy efficiency of their home. It would take 3 to 4 years to pay the additional cost of hiring a company like Aeroseal to seal the air ducts. You probably won't need this type of service unless your ducts are very old and difficult to repair or replace.

Professional duct sealing companies use special technology to seal all duct connections from the inside. Duct sealing is one of those projects where homeowners often ask if they can do it themselves or if they need to hire a professional. Either way, having your ducts properly sealed will help you balance the air temperature in your home and improve air quality. Service Champions is a professional contractor that carries out duct improvement projects, including sealing, cleaning, installation, repair and maintenance. Once you know the process and have determined that duct sealing is the best solution for your home, you can decide whether hiring a professional or doing DIY is more your style. Even perfectly sealed and insulated ducts lose some heating and cooling, especially if they are located in unconditioned areas of the house, such as attics and mezzanines.

In general, the best way to seal ducts is to hire a professional to internally seal the entire duct system. They will then pressurize the duct system with a fan and use a computer to analyze the data and determine how much air escapes through the ducts. According to the EPA, “20 to 30 percent of the air that passes through the duct system is lost due to leaks, orifices and poorly connected ducts”.Sealing your home's air ducts is an important step in maintaining energy efficiency and improving air quality. If you're considering doing it yourself, make sure you understand the process and have all the necessary materials before starting.
