The duct system is a vital part of any building with central air. No matter how new and efficient your AC unit is, you might not have the most effective cooling system if your ducts are leaky. Don't let your cold air escape through leaky ducts and go to waste. Ducts commonly become loose and leaky at the connectors between two sections. This article explains how to seal loose connectors to reduce leaking and ultimately improve airflow into your home.
Checking for Leaks
Most of your duct system will probably be behind drywall. However, many homes have basements and attics that allow you to access some of the ducts via exposed rafters. While you probably aren't going to remove your drywall just to check your ducts, you should try to inspect and fix all of the exposed ducts throughout your home. First, turn on your AC and hold your hand near the connector seams to make sure there is not a stream of cold air. You also need to check for leaks around the connectors that lead from the exterior AC unit into your home. These are vital and they can get nudged apart since they are outside.
Taping the Connector Seams
Even if you do not notice a huge amount of air leakage, you might want to consider taping any duct connector that may get touched or knocked loose. This will not only help seal and prevent air leakage, it will also strengthen the ducks and reduce the possibility of them becoming loose later on. For the best results, don't use common duct tape that you probably already have lying around the house. Instead, you need to buy aluminum foil tape. This tape is completely air proof, so it creates a much better seal. It also has peel-off paper-backing because it is much stickier than normal duct tape. This means it takes a little longer to apply it.
Taping it over the seams can be a little bit tricky because you are working in such confined spaces and the tape is so sticky. But, do your best and make sure you push down on the tape well so there is no chance of further seeping.
In the end, this simple project might help increase the air flow that comes out of your registers and into your home. This is a nice, simple project that doesn't require any rare tools or supplies. Also, it's not too physically demanding. Contact a local repair service, like Shivani Refrigeration & Air Conditioning, for more help.Share
