How long is air duct cleaning good for?

Like any other air conditioning system, air ducts require regular maintenance to ensure maximum efficiency. As a general rule, the National Air Duct Cleaners Association (NADCA) recommends cleaning air ducts every 3 to 5 years. Air duct cleaning lasts between an hour and a full day (or longer, when cleaning commercial HVAC systems). A standard air duct cleaning would last two to three hours and would cover the HVAC unit, the main duct, the room vents and the air ducts themselves.

If air ducts extend over more than one floor, it will take longer to clean properly. The time it takes to clean air ducts will vary depending on the size of the house, the type of ventilation system you have, and how dirty your ducts are. However, on average, it normally takes between two and four hours to clean all of the air ducts in a typical home. Air ducts, like any other air conditioning system, require regular cleaning to ensure maximum efficiency.

The National Air Duct Cleaners Association (NADCA) recommends cleaning air ducts every three to five years. However, in some environments, the need to clean commercial air ducts is more immediate. Food manufacturers, for example, require quarterly, biannual and annual duct cleaning services due to food particles entering their systems, causing mold and pest problems. The same is true for manufacturing operations that create risks of combustible dust. The average duct system must be cleaned every two to five years.

If your system is properly maintained and filters are changed twice a year, you can increase the time between professional cleanings. If your system has never been cleaned and has been active on your property for more than three years, it's probably due to a cleaning. Even a single station can accumulate enough dust and dirt in the system and make it less efficient than when it was first installed. If you have an older building (10 years old or older) and you don't have any record from previous owners of any air duct cleaning, you've probably never had this service or it's been a long time. Cleaning your air ducts properly improves air quality, reduces your electricity bill and gives you peace of mind.

Unfortunately, many components of the system are not easily accessible, making it difficult to visually detect mold in air ducts. Cleaning your air ducts will remove all of these contaminants, improve indoor air quality, and make your life with allergies or asthma better. If you see dust and dirt around the vents, your HVAC system is likely to have a large amount of contaminants flowing through the air ducts. We recommend doing this every 3 to 5 years for the best indoor air quality, but if you don't think your last cleaning was at the last minute, you may want to schedule it earlier. There are many ways to improve indoor air quality, such as cleaning, ventilating the house and adding some plants to the house.

Minimize machine downtime and maintain a clean and safe environment for your employees with an air conditioning system cleaning partner backed by a history of hard work, integrity and a commitment to excellent service. If you or someone in your family smokes cigarettes, this also increases the amount of dirt that builds up inside the air ducts over time. Knowing how long it takes to clean air ducts is a great way to budget your time and energy while ensuring that your family is breathing clean air. Having a company clean air ducts is a great idea for keeping indoor air quality high and removing one more item from the to-do list.
