7 Things You Need to Know Before Hiring an Air Duct Cleaning Company

When it comes to keeping your family healthy, safe and happy at home, the air you breathe plays a significant role. So, if you are noticing dirt, mold, and other substances in your ducts, you will want to contact an air duct cleaning company to get the job done right away.

However, not every air duct company is created equal. You will need to understand how each one operates before opening doors to your home. If you are unsure where to start, here are seven questions to ask before hiring an air duct cleaning expert to ensure you find the right fit.

How Long Has Your Company Been in The Business?

A company that has existed in the industry for an extended period is an excellent indicator of the company’s quality of work and trustworthiness. An organization having a track record of top-quality air cleaning services is likely to have well-educated technicians with many years of experience.

In addition, it shows clients trust and satisfaction with the company’s services. You can be sure the company will do great and safe work when cleaning the air ducts.

What Kind of Equipment Will You Use?

Air duct cleaning professionals can follow various processes to ensure your air ducts are clean. Ensure you ask how the company you are considering plans to approach your situation.

Generally, the procedures include agitating debris out of ducts and pushing the material into a containment system that comprises some form of vacuum. Companies can use various technologies and tools for agitation, such as vacuum, air wands, tentacled air whips, high-pressure blow nozzles, and rotary brushes.

When it comes to duct cleaning, not all vacuums are created equal. So, ensure you ask about the type of cleaning equipment each company use for the job. You will want a company that uses a robust, truck-mounted vacuum capable of handling negative pressure within the whole duct system.

Tiny, handheld vacuums may not offer the suction level needed to clean your air ducts thoroughly. High-quality equipment may cost more in the short term but can deliver powerful results.

Do You Have Reviews and References?

According to research, about 84% of people trust online reviews like personal recommendations from family members and friends. Thus, before signing on the dotted line, ask the air duct cleaning company if they are willing to share any client references with you. Any team with an excellent reputation will be ready and happy to share and provide many references.

Also, you can browse online and research for customers’ testimonials and feedback on the company’s website. It’s always a good idea to get firsthand information from individuals who have been there in your situation. As you browse through, check for language that shows the technician’s capabilities, tidiness, and trustworthiness.

Will Your Technician Assess My Situation First?

In most cases, the homeowners are not sure of the exact level of air duct cleaning that they need. As a result, a technician needs to assess the situation and ask questions about the property before recommending any solution. Although it’s hard to determine without coming to your home, the technician can get most of the answers through a phone consultation before planning an assessment of your home. Here are a few questions they should ask include:

  • When was the last time your air duct was cleaned?

  • Have you ever had your air duct cleaned by a professional?

  • Have you done any remodeling or reconstruction recently?

  • Do you have pets?

The answers will assist the experts in knowing the appropriate level of cleaning you need. You should not trust the team that quotes a price on the spot without taking enough time to understand your situation and even visiting your home and assessing your need.

Can You Provide Proof of Insurance?

A reputable air duct cleaning company will have liability insurance that covers technician injury and home damage during the cleaning process. Avoid hiring a company that can’t provide written proof of insurance. You don’t want to be responsible for accidents in your home by hiring air duct cleaners without adequate insurance cover.

A professional and credible air duct cleaning company will gladly offer you proof of insurance. Otherwise, you should continue searching for a company that will.

How Will You Ensure the Rest of My Home Remain Clean?

Duct cleaning can be messy. However, there are specific steps that technicians can implement to ensure your home remains as safe and clean as possible. These precautions include:

  • Making use of drop clothes to protect furnishings and floors.

  • Placing traps underneath the cleaning equipment.

  • Putting on booties inside your home.

  • Putting magnetic vent covers on return vents to reduce blowback.

  • Protecting the trims and walls by applying plastic guards.

The above steps are only a few of the various steps the technicians can employ to protect your family and property. Ensure you are comfortable with these processes before welcoming them into your home. Maintaining cleanliness is a significant way of demonstrating technicians’ work ethic, respect, and commitment to quality services.


If you have noticed allergies are worsening or have taken some time before cleaning your air ducts, then it might be the time to have your ducts professionally cleaned. By asking these questions, you can rest assured that the air duct cleaning company is safely and thoroughly cleaning the ducts.
