The way your facility can control indoor air quality and keep its thermal comfort relies solely on your HVAC system. Therefore, it is important to keep the system running cleanly and efficiently.
This system of ductwork and piping transports air to different parts of the building. Ducting is precisely designed to provide air, at the proper volume, to the parts of a building that need it.
To help increase the lifespan of your system and to ensure it is operating optimally, it is important to have the air ducts professionally cleaned periodically. Here are 5 signs that your air ducts need to be cleaned.
- Dirty Register Covers
- Lack of Air Flow
- Strong odor from vents
- Signs of Mold
- Dirty Air Filter
Along with normal accumulations of dust and dirt found in all air ducts, several other factors can increase the need for regular cleaning. Different types of contaminants can harm some individuals more than others, especially allergy and asthma sufferers. Children and the elderly tend to be more susceptible to the types of poor indoor air quality that air duct cleaning can help solve as well.
What You Need to Know about Air Duct Cleaning
For the air duct cleaning process to be effective, the entire HVAC system should be cleaned. If all components of the system are not cleaned properly, it can result in recontamination of the entire system, which would significantly reduce the benefits of cleaning. Just as you wouldn’t clean only half of your bathroom, you also would not want to clean only part of your HVAC system.
According to the National Air Duct Cleaners Association (NADCA), cleaning the entire HVAC system should include the following components.
- air ducts
- drain pan
- air plenum
- blower motor and assembly
- heat exchanger
- air filter
- air cleaner
The Two Main Components to HVAC Cleaning
1.Breaking Contaminants Loose
The correct way to clean your HVAC system is to start by removing any type of contamination that is found. This will require particular devices that are designed to loosen contaminants from the surfaces. Commercial-grade equipment such as brushes, air whips, and compressed air nozzles are used.
When cleaning the entire system, it will be placed under continuous negative pressure by using a vacuum to prevent the spread of contaminants. The continuous negative pressure allows very fine particles to be extracted as they release into the air. This will ensure that the particles are not released into the building’s interior when the system is turned back on.
The Benefits of HVAC Cleaning
Improved Air Quality
Indoor air quality can be compromised by dirty air ducts. Everyday occupancy of a building produces contaminants and air pollutants, like dander, dust, and chemicals. These are recirculated many times a day through the HVAC system.
The contaminants also build up in the ductwork over time along with other pollutants. For example, if the building had a fire or flood, the residual smoke and debris along with other air contaminants will further affect the air ducts.
These elements can contribute to health issues, especially for people with respiratory issues, autoimmune disorders, or environmental allergies. Removing the health hazards at the source can improve the health of the people exposed to the system, as well as increase efficiency, saving you money and maintenance.
Removes Pathogens and Mold
Mold can grow, particularly in humid climates, and spread throughout the ductwork. Many people exhibit some form of allergic sensitivity to mold, and in severe cases, mold may even aggravate respiratory conditions. Cleaning your ducts also removes droppings left behind by rodents and other small animals that may enter the ducts from the outdoors.
If your HVAC is on and an unpleasant smell fills the room, it’s a sign that your air ducts need cleaning. The basement smells, damp odors, or animal smells can form due to a lack of ductwork maintenance. Commercial air duct cleaning eliminates the sources of these odors and helps to prevent them from recurring.
According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling space is wasted. If your air ducts remain clogged for too long, they will work harder to circulate air and your HVAC system will run longer throughout the day, shortening its lifespan.
