How And Where To Check For Duct Leaks

Now that you know how important it is to prevent leaky Charlotte air conditioning ducts, you’ll need to be able to understand how and where to check for leaks. The very simple answer is that you will discover that air will naturally find its way through any type of material if it is not airtight. This is due to the fact that circulating air is always looking for both a balance in pressure as well as temperature.

Warm air that is moving about through a ductwork installed in cool crawlspaces is just looking for a way to meet up with any cold air that exists on the other side of the duct work. Circulated air remains the pro at mingling and is more adept than any high society socialite working the floor at a charity event. When you add pressure to any system, this only forces the air to work a lot more seeking an escape route.

A Charlotte HVAC unit will force conditioned air circulating throughout the house through both return and supply ductwork. The supply ducts will bring heated air up from the house furnace, or cooled air coming from the air conditioning system, through each room heat register. Return ducts then draw cold air out of each room in the home returning it to the furnace where it is re-heated. This makes it extremely important that all system ducks are properly sealed. This will reduce heat loss but also works to improve system air circulation. This produces a proper air balance maintenance throughout the entire house.

You will find leaks where any two pieces of duct connect. The furnace is where you might find pronounced leakage since this is where main ductwork meets the furnace air handler. Here is where the highest air pressure is found. Other areas where leaks are commonly found include the point where small ducts shoot off, branching away from the main supply duct, also wherever the ductwork bends.

Don’t forget to check where straight pieces of ductwork are also connected. Make sure to check the end fitting at the register because this is typically a common spot for leakage.
