Since most of the dust in your home’s ducts tends to stay in the ductwork, air duct cleaning isn’t required regular maintenance in most homes. In fact, the Environmental Protection Agency advises homeowners to only clean air ducts when the homeowner detects mold growth, an insect or rodent infestation, or excessive dirt and debris inside the ductwork. But when those problems do arise, most homeowners lack the expertise and tools required to thoroughly clean air ducts themselves. This is a job that requires the expertise of a professional service.

Air duct cleaning services can vary dramatically in price and quality, making choosing the right professional a confusing process. While it’s vital to hire a service that adheres to the National Air Duct Cleaners Association (NADCA), there are other factors to consider. This guide will discuss what attributes are crucial to consider when vetting a duct cleaning service while also reviewing some of the country’s most reputable air duct cleaning companies.

What to Consider When Choosing One of the Best Air Duct Cleaning Services

Since quality HVAC duct cleaning can vary greatly from service to service, it’s important to consider a few important factors when vetting a company, including certification, cleaning methods, and customer service. Ahead learn more about these and other crucial attributes of air duct cleaning services.

The first step in selecting a duct cleaning service is identifying which ones serve the home’s location. An online search is typically one of the best ways to identify local duct cleaning services. Keep in mind that some services may only serve commercial properties while others will service residential or both. It’s also important to note that some national duct cleaning companies provide different services in different parts of the country. Ensuring the office that serves the home’s location offers the appropriate services is crucial when hiring a company.

Many regional and national AC duct cleaning services allow customers to sign up for service online or by phone. While online scheduling may be more convenient, a person-to-person phone call allows the homeowner to communicate vital information, such as the condition of the ducts, details about the home’s HVAC system, and other pertinent information. If the need for duct cleaning is urgent—as in the case of a rat infestation or mold problem—a phone call will typically expedite service more quickly than filling out an online service request form. Keep in mind that some companies offer consultations or in-home inspections prior to performing the labor. While this may seem like an inconvenient extra step, a company willing to perform an inspection before cleaning the ducts is more likely to do the job right than one that is not.

Any duct cleaning service worth its salt should have a National Air Duct Cleaners Association (NADCA) certification. The NADCA is responsible for developing and researching standards for cleaning air ducts. The duct cleaning service must adhere to these standards and have at least one Air System Cleaning Specialist (ASCS) on staff to earn this certification. An ASCS has taken classes in these standards and passed an exam to achieve this certification. Most air duct cleaning services display their NADCA certification prominently on their web page.

In addition to NADCA certification, a homeowner should also check if the company is a member of the ACCA (Air Conditioning Contractors of America). The ACCA sets standards contractors should follow when working on indoor HVAC systems.

Finally, reputable air duct cleaning services should also adhere to the Environmental Protection Agency (EPA) guidelines regarding duct cleaning.

Understanding the cleaning methods is crucial knowledge that allows a homeowner to monitor the work. Most services will begin with a visual inspection of the ducts, often using a video camera that extends into the ducts to survey their condition. Next, the technician will attach a large vacuum device from the truck to one of the ducts. The technician must seal each register in every room of the house to create the negative pressure required to suck dust out of the vents. After covering all registers, the technician will turn on the vacuum to create negative pressure throughout the ducts. They can now clean each duct by covering and uncovering each register one at a time. While the ducts will be the focus of the cleaning, a good duct cleaning service will also clean other parts of the HVAC system, including blower motors, evaporator coils, and drain pans. Finally, the technician should replace any filters with new ones.

In addition to duct cleaning, many duct cleaning companies offer other services that might interest a homeowner. Additional services duct cleaning companies offer include carpet cleaning, dryer vent cleaning, and HVAC repair. Some companies will bundle services, making them more affordable than purchasing each service individually.

Whether hiring a plumber, electrician, or air duct cleaning company, customer service is key to having a good experience. A company that offers good customer service should be willing to assess the condition of a home’s ductwork and provide a detailed estimate of the work before requiring a customer to commit to the service. A quality company will have customer service representatives available via phone, email, or online chat.

How We Chose the Best Air Duct Cleaning Services

We considered numerous important criteria in reviewing more than a dozen different air duct cleaning services for our list of the top services. There are a fair number of imposters when it comes to air duct cleaning services, so reputation is key. The services we chose have been in the business for 20 years or more. All the companies on our list have NADCA certification and a proven track record of providing quality duct cleaning. These services use best practices when cleaning ducts, including negative pressure technology and vacuum systems with HEPA filtration. Since ducts aren’t the only component in an HVAC system that can clog with dirt, we chose companies that also clean blowers, registers, heat components, cooling coils, and other integral HVAC parts.

Before You Use One of the Best Air Duct Cleaning Services

Before choosing a duct cleaner, determine if the service is needed at all. If an examination of the home’s ducts reveals no large deposits of dust, then there is probably no need to clean the ducts, according to the Environmental Protection Agency. It is normal for the return registers to collect dust as they draw in air and dust from the room. A dirty register can be cleaned with a standard vacuum. That said, if you do have family members with severe allergy symptoms or unexplained illness, it may make sense to have a closer inspection of the ducts by a professional service to determine if a cleaning is needed.

Cost of Using One of the Best Air Duct Cleaning Services

The cost of hiring a company to clean the air ducts in a home averages between $269 and $486. The amount of ductwork in the home and its accessibility coupled with the home’s location impacts the price. That cost can increase significantly for ducts that require mold removal or pest extermination. Pest extermination can add $150 to $500 to the cost, while mold and mildew removal can add $600 to $2,000.

The Advantages of Using One of the Best Air Duct Cleaning Services

When a quality air duct cleaning service does the job, there can be many benefits. Clean ducts can improve a home’s overall air quality by removing excess dust, pollen, mold, and mildew inside the ducts that would otherwise circulate into the air. Other advantages include:
