Know the Signs that Your Air Ducts Need Cleaning

Several telltale signs indicate that your air ducts need cleaning. If you notice increased dust in your home, unusual odors when your HVAC system kicks on, or a significant increase in your energy bills, it’s time to call Cardinal Plumbing for an air duct cleaning service.

Our experienced professionals will evaluate your system, identify problem areas, and use state-of-the-art equipment to clean your air ducts thoroughly. Regular cleaning can help maintain efficient HVAC performance, reduce respiratory issues, and improve your home’s overall indoor air quality.

Common Problems with Air Ducts

Air ducts are susceptible to a wide range of issues that can, in turn, directly impact your HVAC system, home, and health. If left unchecked, these problems may damage important and expensive components.

Air Contamination

Dust, pollen, mold, and other fine particles that collect in ductwork can contaminate the air in your home, causing anything from sneezing and coughing to airborne diseases. Unwanted particles can collect indoors in concentrations much higher than outside, which can be very dangerous.


Excessive accumulation of material can eventually block ducts, impeding airflow through the system. Insect colonies, rodent infestations, and bird nests can completely block a duct, disrupting your HVAC system and potentially exposing your family to harmful pathogens.

Air Leaks

A loss of air from ducts forces your air conditioning system to work harder. It can cause components to overheat, wear out faster, and fail, causing the AC to break down unexpectedly. At the very least, an air leak will prevent the system from maintaining a comfortable temperature in your home.

Poor Duct Seals

The grills and registers are important for airflow, but if they’re not well-sealed, dust, debris, and insects can get inside with little to stop them. A significant amount of conditioned air can escape through poorly sealed areas, so a professional must address any sealing issues before they become costly.

Design Flaws

If your system has an unusual number of kinks and twists, airflow can be blocked or restricted to the point it negatively impacts the efficiency of your air conditioning system. A bad design can make it impossible to get comfortable no matter what you set your AC to.

Frequently Asked Questions About
Air Duct Cleaning Services

Replacing air ducts might sound easy, but it’s an incredibly complex process. In a typical central air system, the air ducts connect across a large system. They bring air in and out of all the rooms of your home. To replace those ducts, a technician needs to go through and make sure every one of those ducts is changed out with new ones.

Just as your HVAC units won’t last forever, your air ducts won’t be eternal. In fact, they may not last as long as your heating and cooling system. In most homes, the ducts need to be replaced once every ten to 15 years. If you fail to replace your ducts in a timely manner, you could experience several issues. First, you might have high energy bills.

One of the most obvious signs of bad ductwork is a strange noise coming from your ducts or vents. As soon as you notice a change in your system’s sound, consult with a professional. You could have leaks or holes within your ducts. Unless you act quickly, you could have serious problems. High energy bills, frequent repairs, and other complications often occur when there are duct leaks.
