Were you aware that the indoor air quality could be three to five times worse than the air you breathe outside? We all need clean air to breathe and live a little longer. Ensuring the air you breathe is clean and free from contaminants is crucial for maintaining a healthy indoor environment. 

One often-overlooked aspect of achieving this is proper maintenance of the heating/cooling system, particularly for air duct cleaning. 

It can have an impact on the indoor air quality and efficiency of your HVAC system. Over time, dust, dirt, allergens, and even mold can accumulate within the ductwork, leading to various health and performance issues.

It's crucial to understand how air ducts are cleaned to ensure your HVAC system operates at its best. Here, we will walk you through the step-by-step process of cleaning the air ducts. We shed light on the other aspects of it as well. 

Air Duct Cleaning- What is it?

Indoor air quality is a concern that often flies under the radar for many individuals. Increasingly overwhelmed by pollution, the demand for air purifiers has surged. In this context, the importance of air duct cleaning has also come to the forefront.

Cleaning the ducts is vital to maintain a healthy indoor environment. It involves the comprehensive cleaning of the entire duct system, which has the supply, intake, and return vents. This process employs professional air duct cleaning equipment to effectively remove dust, debris, allergens, and potentially harmful contaminants accumulating over time.

 Air duct cleaning may extend to other components of the HVAC system in addition to ductwork. It can include cleaning the registers, fans, grills, and even the HVAC unit itself. This service can also involve cleaning that essential heating component for those with a furnace. 

Fortunately, some companies specialize in providing air duct cleaning services. You can hire them periodically to ensure your indoor air quality remains at its best. It would provide a healthier and more comfortable living space. 

Equipment Needed To Clean Air Ducts

Cleaning the air ducts is not an easy task. It requires a professional knowledge and tools to do so. There are some handheld instruments and heavy machines to clean the air duct.

Moreover, air duct cleaners have various inspection tools. Each serves a specific purpose in ensuring cleanliness and functionality. These tools can vary from a basic mirror to more advanced equipment.

It includes periscopes or CCTV camera systems with flexible cables designed to reach the hard-to-access sections of the ducts. Inspection tools come into play, particularly during issues such as clogs or persistent foul odors emanating from the vents. 

Professionals rely on some fundamental tools for the actual air duct cleaning process. These include brushes, vacuums, and other agitation devices designed to dislodge and remove accumulated dust and debris. 

Two types of vacuum collecting devices are NADCA standard in any professional or personal sphere- 

  • Truck- and trailer-mounted
  • Equipment
  • Portable tools

The trailer or truck-mounted tool is generally more powerful than the potable one. They suck the debris from the location using a hose attached to the ductwork.

However, people can bring a portable one into the facility easily. It allows the vacuum source to become closer to the ductwork. The biggest portable vacuum has a 5,000 cubic feet per minute suction power. 

Both kinds have their pros and cons. You need to weigh them according to your needs. In addition to the above two, professionals also use air compressors and disinfectants.

The NADCA suggests cleaning not just the air ducts but these following components too- 

  • coils
  • registers
  • drain pan
  • grills
  • blower motor and assembly
  • air plenum
  • heat exchanger
  • air cleaner
  • air filter

Incorrect cleaning methods can inadvertently dislodge pollutants and debris. It may cause them to flow back into your living space through the air ducts. Through the correct method, the professionals safely extract them using the specialized techniques employed by professionals.

It's best to get air ducts professionally cleaned to ensure a thorough and without causing unintended consequences.

How Are Air Ducts Cleaned Professionally? – A Step by Step Process

If you are wondering how to clean out air ducts properly, here is a step-by-step process for you. We would genuinely advise you to seek professional cleaning help as cleaning air ducts are tricky. If you hire trained cleaning staff, here’s what goes into the cleaning process- 

Step 1- Inspection of the Ducts

The first step in getting the air ducts cleaned is to check them. The professionals should inspect the ducts leading to supply and return registers. This step is vital for two main reasons- 

First

To see the buildup level in the ducts and verify the distinction after the cleaning process. You may come across some cleaning professionals who use cameras to assess the extent of buildup in the duct. 

Second

Professional air duct cleaning is a chance to assess the ductwork for any kinks or leaks in flexible ducts. In this step, they can also repair or replace damaged ductwork. 

Step 2-The Negative Pressure

The air duct cleaning professionals may use truck-mounted vacuums, or portable vacuums to suck debris and dust from the ductwork. But before suction and scrubbing the ducts, technicians should do the following- 

Connecting the vacuum hose

Initially, the technicians should connect the large hose to the duct leading to the air handler. It is the main part of your heating and cooling system. Sometimes, they may have to cut an access hole in the duct to securely insert the vacuum hose. After the completion, the technician ensures they seal the hole properly. 

Sealing the registers

After the hose connection, the technician should use adhesive to seal each register. It is important as even the most powerful vacuum collection could fail if the registers remain uncovered. 

Activating the vacuum unit

With all the preparatory steps complete, professionals should activate the vacuum unit. It establishes negative pressure in the ductwork. As a result, the dust is collected in the device as they become loose, due to the blow and brush effect. 

Step 3- Agitate dust

Once the negative pressure is in the system, professionals uncover each register. They will then clean the ducts one at a time.

We think you should find an experienced cleaning team known for fast and efficient work. They use rotating brushes, simple vacuum cleaners, and compressed air tools to ensure it sucks everything in the collection device.  

An improperly trained professional may move forward after a speedy brush in the air compressor and drops of disinfectant.

Step 4- HVAC System and Furnace Cleaning

After the completion of the ducts and vents cleaning, the HVAC system undergoes a comprehensive inspection. This inspection involves components such as the air blower motor, furnace, drain pan, evaporator coil, and other vital elements. These parts come under the standard NADCA standards. 

The technicians are responsible for maintaining a clean workspace and ensuring dust-free space. Furthermore, they should offer a walkthrough to see how the air quality and system performance have improved.

This commitment to cleanliness and transparency is part of the professional service you can expect.

Air Duct Maintenance Tips

There are certain things your service provider needs to remember regarding maintaining the air duct. Every day, the commercial air spaces carry cool and warm air, so it would be good to observe proper maintenance. Just cleaning them is insufficient. One needs to deal with these subtle changes. 

 Here are a few tips-

1. Schedule a duct test 

To ensure the cooling and heating system fires on all cylinders, consider testing the pressure in the duct system. Doing so will help you know about air leaks and show the balance required in the system.

2. Use high-efficiency air filter

The staff should follow the manufacturer's recommendations for the highest-efficiency air filter suitable for the heating and cooling system. It helps improve indoor air quality and system efficiency.

3. Replace air filters regularly

Changing the air filters regularly as recommended by the manufacturer or your professional. It ensures that your system can operate efficiently and maintain good air quality.

4. Change filters if clogged

 If the staff notices the filters become clogged or dirty, let them change more frequently. The clogged filters can hinder airflow and strain your system.

5. Request cooling coil and drain pan cleaning

Ask for cooling coil, and drain pan cleaning when scheduling air duct maintenance. It helps maintain system efficiency.

6. Seal off the supply and return registers

During construction or renovation work that generates dust in commercial spaces, air duct cleaners should seal off the supply and return registers. Also, people should refrain from operating their heating and cooling systems until they clear the dust to prevent contamination.

Regular air duct cleaning is about ensuring the health and well-being of your family. You also reduce expenses, extend the life of your HVAC system, and create a comfortable breathing environment.  

Benefits Of Duct Cleaning 

Many American buildings have a proper heating and cooling system that needs continuous maintenance. You should get the air ducts cleaned once every two or three years, but it largely depends on the use.

Hygiene without Allergens 

Recent studies show how allergens are the primary cause of ill health among many. Up to 40% of the world’s population suffers from allergies and diseases related to it, like asthma. The figures will increase in the future. 

Dust mites, pet dander, pollen, and other allergens are likely to accumulate in your air ducts. It aggravates allergies and asthma symptoms among family members. Cleaning your air ducts removes these allergens, leading to a healthier indoor environment.

Those with allergies or respiratory conditions often notice significant improvements in their symptoms after a thorough duct cleaning. It allows for a more comfortable and enjoyable living space.
