How often you should clean your air ducts depends on your situation. If you or someone in the home has asthma or is acutely allergic to certain airborne materials or pollen, regular duct cleaning may be helpful. The Environmental Protection Agency doesn’t have an official position on the necessity of air duct cleaning unless the ducts have been contaminated by rodents, insects or mold, or you are aware of particles blowing out through the vents. The EPA recommends you have your air ducts cleaned on an as-needed basis. The National Air Duct Cleaners Association (NADCA) suggests having air ducts cleaned every three to five years.
Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
The amount of time air duct cleaning takes can depend on how extensive your duct system is, how old your air ducts are, and whether they have ever been cleaned. On average, expect a standard size home (between 2,000 and 3,000 square feet) to take 2-5 hours for one to two technicians to clean. Here are the proper protocol and equipment you should expect from a professional duct cleaning service, as recommended by the Environmental Protection Agency:
- All doors and access ports opened to ensure the entire duct system is inspected and cleaned.
- Thorough system inspection prior to cleaning to identify possible asbestos-containing materials. If asbestos is present, specially trained and equipped contractors must do the removal.
- Use of approved vacuum equipment that exhausts particles outside of your house. If the vacuum exhausts inside your home, it must be HEPA equipment.
- Furnishings and carpet covered and protected.
- Soft-bristled brushes only on fiberglass duct board and sheet metal ducts internally lined with fiberglass.
- Ductwork properly protected.
- Adherence to guidelines and practices set down by the National Air Duct Cleaners Association.
The national average dryer vent cleaning costs range from $190 to $260. Dryer vent or duct cleaning costs can vary based on where you live in the country and what ductwork repairs may be required. Duct cleaning pros will use a brush cleaning method, a forced air vacuum, or a combination of the two to remove lint and other debris that can collect in your dryer duct, lint trap housing and vent. If left unchecked, this buildup of highly flammable debris can catch fire and lead to a home fire, says the U.S. Consumer Product Safety Commission. In addition to home safety, a great reason for regular cleaning is the money you’ll likely save on energy bills and improved indoor air quality. Pros may offer a lower rate on their dryer duct cleaning costs when you also hire them to clean your entire HVAC duct system. To ensure you’re working with a pro who will keep your home as safe as possible, read their reviews and check whether they have been certified by a reputable organization such as the National Air Duct Cleaners Association (NADCA) or the Chimney Safety Institute of America (CSIA). Many duct cleaning pros will also show you before-and-after photos as proof of the cleaning.
If you’re concerned about dust, allergens or mold, it may be time to have your air ducts cleaned. The national average cost for air duct cleaning ranges from $190 to $250. Air duct cleaning costs will vary based on a number of factors such as your location in the country, the age and condition of your air ducts, the number of linear feet to be cleaned, and any repairs your ducts may need. HVAC cleaning companies should clearly outline what is included in their services and at what rate, so always make sure you understand and have a written agreement before work begins. Here are some examples of average air duct cleaning costs:
- Tiered pricing for different levels of service:
- Standard cleaning: $100, which may include truck-mounted industrial vacuums, high-pressure air wands and air snakes to clean all supply and return vents, branch lines, and main trunk lines.
- Advanced cleaning: $200, which may include standard cleaning services, plus rotobrush or viper clean sweep in the main trunk lines.
- Ultimate cleaning: $400, which may include advanced cleaning, plus insertion of a viper microline into all vents to force debris down the branch lines and into the main trunk lines, to be handled by the viper clean sweep. Typically, all ductwork surface is contacted, before-and-after photos are provided, and the furnace is cleaned.
- A flat rate for unlimited vents: $289.
- Additional fees for larger houses: $20 for each additional 500 square feet over 2,500.
What’s the best way to set up a consultation or an appointment with a general contractor during the COVID-19 pandemic?
To set up a consultation or appointment with a general contractor during the COVID-19 pandemic, start by performing an online search for local professionals near you.
Message the contractor, and see if they are willing to set up a video consultation call instead of an in-person site visit. With video chat, the contractor may be able to assess the scale of the project, give you better information on what needs to be done and perhaps provide an estimate. Be sure to discuss virtual payments, as well as general strategies for staying safe.
Currently, many general contractors are using common digital payment services like PayPal, Venmo, Square Cash, Zelle, Google Pay and more. And more will likely adopt these and similar platforms as coronavirus continues to force companies to take on digital capabilities.
Contact general contractors beforehand to discuss whether they accept digital payments, and take all necessary measures to meet social distancing recommendations. You can also compare general contractors side-by-side online to see which ones accept digital payments.
If you decide to hire a general contractor, avoid any physical contact, don’t shake hands, keep 6 feet of distance between you and the pro and sanitize all involved surfaces. Also, use digital platforms to communicate and make payments.
To find out whether a general contractor is considered essential in your area during the current coronavirus pandemic, visit your city or state’s government website, which will have information on essential services.
Find information on national recommendations by visiting CISA’s Identifying Critical Infrastructure During COVID-19 webpage. However, not all jurisdictions follow CISA’s definitions of critical infrastructure.
General contractors perform manual work and typically need to be present to complete their projects. However, if you come across a profile that states the contractor is offering remote services, ask what those services include. You can also ask if they can perform a consultation via video call and if they can do the job while following guidelines from the CDC and local agencies.
Provided the project is located inside your home, completing the job would require a general contractor to enter your home. But if your project is located outdoors, a general contractor will likely not need to enter your home. Discuss your options with general contractors in your area before hiring.
