Signs Your Ducts Aren’t Sealed Properly

Apr 23, 2021

Your HVAC ducts are like the circulatory system of your home. Ductwork consists of supply lines that deliver conditioned air to your rooms while return ducts bring air back to the HVAC unit to be warmed or cooled. If the ductwork is leaking, you might notice various signs indicating your air conditioning system is under stress. Leaks can occur due to holes, corrosion, disconnections, and other types of damage. Improper sealing can reduce energy efficiency and even the life of your AC, so it’s important to recognize the following signs.

Hot and/or Cool Spots

If your ducts aren’t properly sealed, the temperature of your home may be inconsistent from room to room. Some rooms may be hot and stuffy while others may be frigid. This is a sign of an airflow issue, which can be caused by a hole or loosened connection in your ductwork. When air isn’t properly circulated, it doesn’t reach every room in the same amounts.

Rising Energy Bills

Energy costs can fluctuate during the year. However, if your monthly bill is much higher than the same time a year ago, even a small leak can be causing your HVAC system to work harder. Maintaining the set temperature is more difficult if the system is losing air. If your bill is significantly higher, have an AC contractor inspect your ductwork.

It’s Getting Dustier

Every home has dust but if it starts accumulating in unusually high levels, a duct leak could be the cause. HVAC filters catch dust effectively. The leak could be beyond of the filter, allowing dust to enter the system and circulate, reaching deep into your home via air ducts and supply vents.

Ductwork Not Well Insulated

A lack of insulation can lead to condensation. The dampness can lead to corrosion, which in time causes small holes to form. Mold and mildew can grow in this damp environment as well, emitting a musty smell throughout your home. When a ductwork sealing contractor visits your home, have them evaluate your insulation as well, and correct any issues they find.

How to Find Sealing Issues

It’s a good idea to check your ductwork occasionally. If you haven’t done so in a while, look for signs of visible damage, such as kinks or gaps. Exposed ductwork in your garage, attic, or crawlspace is susceptible to leakage; since they’re usually not as well insulated, these ducts can lose air which then escapes your home entirely. Plus, the air is leaking into rooms that aren’t as frequently used, decreasing efficiency further.

Another reason to check your duct sealing is if you or someone at home is struggling with asthma or other respiratory issues. Allergens, irritants, and even fumes may be entering your ducts, which can cause a variety of problems. But you might not know where all your ductwork is. Some ducts may be hidden above the ceiling or behind walls where you didn’t know they were located. A professional can identify where your air ducts are and perform a thorough evaluation.
