    Are Home Duct Cleanings Worth It?

    Posted by CleanAlert Blog Team on Jul 13, 2016 10:00:00 AM

    Duct cleaning has grown to be popular in recent years, with commercial cleaning services popping up everywhere. But is the service worth it, or is it simply a scam? Here’s some information to assist you in whether or not your home might benefit from having the HVAC ducts in your house cleaned.

    Duct Cleaning Services

    Professional duct cleaning services use specialized blowers, vacuums, and brushes to clean out the supply, intake, and return ducts throughout your home. Duct cleaning should also include a thorough cleaning of the air handler, registers, grilles, fans, motors, housings, and coils of the HVAC system.

    Currently, there is no research that proves that routine duct cleaning enhances the air quality or reduces dust in your home. There is, however, evidence that dirty heating and cooling coils, motors, and air handling units can make your HVAC unit less efficient.

    While duct cleaning alone doesn’t appear that necessary, there are cases where cleaning the HVAC unit and ductwork could be useful.


    Should I Have Ducts Cleaned?

    Due to growing concerns about indoor air quality, it’s easy to convince homeowners that their ducts need cleaning. But unless ducts are really dirty, there’s no reason to clean them. Similarly, the EPA recommends cleaning only if the ducts and HVAC unit are contaminated.

    If done properly, duct cleaning doesn’t hurt; but it’s not anything that needs to be on your regular home maintenance list. You seemingly don’t need to have your ducts and HVAC system cleaned unless:

    Renovation: If your home has been remodeled – especially if there was asbestos abatement, lead paint removal, or significant dust – your ductwork may need to be cleaned. Ducts should be sealed off during home renovations; but if they weren’t, dangerous dust and debris may become lodged inside the ductwork.

    Animals: If there’s evidence of animal infestation or nesting in your ducts or HVAC system, have the animals removed then clean the ductwork and HVAC unit.

    Mold: If there is visible mold growth inside the ductwork, the ducts and HVAC system should be cleaned.

    Contaminants: If noticeable debris, pet hair, odors, or other contaminants are being released into the room through the ducts after the registers have been cleaned and vacuumed; then the ducts may need to be cleaned.

    Illness: If someone in your family is suffering from an unexplained allergy-related illness, and you’ve taken every other possible step to decontaminate your home, you may want to contemplate on having your ducts cleaned to see if the HVAC system was the culprit.

    How To Avoid Duct Cleaning Scams

    While there are reputable, professional HVAC cleaning services out there, there are scams as well. Anytime scare tactics can be used to make the case that your home might be “unhealthy,” homeowners run the risk of being frightened into emptying their checkbooks.

    Here are some tips for avoiding scams if you decide to look into having the ducts and HVAC system in your home cleaned:

    Full Service: Don’t settle for just duct cleaning, ensure the cleaning service is also intending to do a full cleaning of the heating/cooling unit.

    References: Get and check references in your area to find out what was given for the money, and if customers were satisfied.

    Estimates: Request for written estimates from at least three HVAC cleaning services. A reputable company should provide a free inspection and estimate.

    Avoid Gimmicks: Ads for “$79 whole house specials” are scams. At most a few ducts will get a very cursory vacuum; and at worst, you’ll end up persuaded into a much more expensive package. High-quality duct and HVAC cleaning should cost upwards of $500, take several hours with sophisticated equipment, and involve multiple workers.

    Certifications: The cleaning company should be certified by the National Air Duct Cleaners Association (NADCA), which sets standards for HVAC system cleaning. The EPA does not certify duct cleaners, so avoid anyone making that claim. Check for appropriate licenses and insurance – some states require a license for duct cleaning while others don’t.

    Check Standards: The NADCA presents guidelines for professionals and customers on safe duct cleaning. If your ducts are insulated, the professional should follow the guidelines of the North American Insulation Manufacturers Association (NAIMA).

    Verify Results: You should be offered a complete visual inspection of the HVAC system and ductwork, either in person or by remote camera. Make sure that every single duct is clean, and request on an inspection of the inside of the HVAC unit, before paying for the service.

    Don’t Get Fooled: Keep in mind that intake ducts (room ducts that return air to the heating/cooling unit) are likely to be dirtier than supply ducts (which deliver conditioned air from the HVAC unit) since they often don’t have filters. Make sure any “before-and-after” photos are of the supply ducts, where it’s most important that the air is clean.

    Avoid Sealants and Sprays: Both the EPA and the NADCA advise against the use of sprayed sealants or other possibly harmful chemicals inside air ducts. Biocides and anti-microbial treatments are also iffy since the chemicals may cause more harm than good to your health. No chemicals are currently registered with the EPA for use inside ductwork.

    Avoid Steam Cleaning: Any duct cleaning involving steam or moisture should be avoided.
