The Best Ways to Tell You Need Duct Sealing


Leaky ducts are a problem that often lies hidden in a home for a long time. People don’t have easy access to their ductwork, so they tend to assume that all is well with it.

But leaky ducts are a common trouble for HVAC systems and they lead to massive energy loss, uneven heating and cooling, humidity fluctuations, and even indoor air quality contamination.

We’re here to give you the knowledge necessary to detect whether or not you have leaky ductwork. Then you can call our experts for duct sealing in Jacksonville, AR that will restore your ducts to their original airtight condition and ensure your HVAC system always works for you, not against you.

Unexplained High Energy Bills

The most devastating trouble from leaky air ducts is that they allow heated and cooled air to escape before they reach the rooms. That’s air you’ve already paid to condition, which means money going to waste along with the air.

In fact, up to 30% of the air in the ductwork can be lost to leaks, and that will add up to a significant increase on your energy bills. When you see a rise in heating and cooling costs that you can’t explain, it’s a good reason to call for technicians to test the ducts to see if they need sealing.

Uneven Heating and Cooling

Are you or members of your household noticing hot and cold spots around the house? Rooms that seem to always have the wrong temperature when the HVAC system is running, even though the rest of the rooms are fine?

There are several possible reasons for this to occur, and leaky ducts are one of the most common. Technicians can check your HVAC system as well as the ducts to discover if duct sealing is the answer. 

Low Airflow from Vents

The reason ducts need airtight sealing along their length is to help the HVAC system maintain air pressure. Air leaks allow that pressure to drop, resulting in weak airflow coming from room vents.

This will not only affect the vent connected to leaky ducts, but the entire ventilation system. If you notice sluggish airflow from the vents, the problem is likely duct leaks or issues with the blower fan. (We recommend you check the air filter first, since if it’s clogged it will also create this problem.)

Musty and Moldy Odors from the Vents

Leaks in the ducts not only allow air to flow out, they allow air to flow in. Because ducts are located in closed-off areas of a house, such as the attic and between walls, air leaks will draw in stale, dusty, and sometimes even moldy air—and this air will get pushed out into the living spaces. We recommend you call us to check on your ductwork and the HVAC system when you notice these odors.

Our team will perform air duct testing to find out if your ducts have leaks and how extensive they are. From there, we’ll take care of the duct sealing or other service necessary to restore your HVAC system.
