Sealing Your Home's HVAC Ducts: A DIY Guide

Are you looking to take on duct sealing as a DIY project? If so, you've come to the right place. In this article, we'll provide you with the basics of duct sealing and gap repair techniques in most modern systems. To start, seal any air leaks with putty or metal tape and insulate any ducts that are accessible, such as those in attics, mezzanines, unfinished basements, and garages. Never use adhesive tape, as it is not durable.

Sealing ducts from the inside out is a much more complicated process and will likely require the help of a professional. Essentially, what they will do is spray the inside of the duct with a liquid rubber sealant. If there is a gap on the side of one of these lines, the repair can be as easy as applying adhesive tape to seal the hole. In a duct system, the main line is rarely made of flexible ducts, but is more likely to be comprised of metal or fiberglass. Most homeowners don't think about sealing their home's air ducts, but it is an important step in maintaining the energy efficiency of their home.

Even the smallest gaps in the main duct pipe can be sealed with basic self-made caulking or adhesive tape applications. Having your ducts properly sealed will help you balance the air temperature in your home and improve air quality. Professionals 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. Sealing your home's HVAC ducts is an important step in keeping your home energy efficient and improving air quality. With this guide, you can take on this project yourself or hire a professional for more complicated tasks.

Either way, you'll be able to enjoy a comfortable home with improved air quality.
