Introduction

Homeowners near Northridge, air duct cleaning is an important maintenance task for keeping your HVAC system running efficiently and improving indoor air quality. However, the industry is filled with scammers and fraudulent companies that prey on unsuspecting homeowners. These scams often involve bait-and-switch pricing, unnecessary services, and unqualified technicians.

In this article, we’ll expose the most common air duct cleaning scams, how to identify legitimate services, and what steps you can take to protect yourself from being ripped off.

Common Air Duct Cleaning Scams

1. The Too-Good-to-Be-True Price Scam

One of the most common scams involves companies advertising extremely low prices, such as “Whole house air duct cleaning for $99”. Once they arrive, they claim your system is contaminated with mold or excessive debris, pressuring you into expensive add-ons.

How to Avoid It:

  • Be skeptical of low-ball offers—professional cleaning typically costs between $300 and $600.
  • Ask for a detailed price breakdown before scheduling service.
  • Read customer reviews to check for complaints about bait-and-switch tactics.

2. The Mold Scam

Some disreputable cleaners falsely claim they found toxic mold in your air ducts. They may even show fake test results or staged photos to convince you that expensive remediation is necessary.

How to Avoid It:

  • Mold should be tested by a certified third-party lab, not a cleaning company.
  • Ask for visual evidence before agreeing to any mold remediation services.
  • Work with companies that are licensed in mold removal.

3. The Unnecessary Sanitation Scam

Many scammers push expensive chemical sanitization that isn’t needed for most ductwork. They claim it will eliminate all bacteria and allergens, but in reality, improper use of these chemicals can damage your HVAC system.

How to Avoid It:

  • Most homes do not need chemical sanitization unless there’s a verified mold or bacterial problem.
  • Request a list of chemicals used and their safety information.
  • Avoid companies that insist on mandatory sanitization.

4. The High-Pressure Upselling Scam

Some companies start with basic cleaning but pressure homeowners into purchasing additional services like UV lights, extra filter replacements, or duct replacements that aren’t needed.

How to Avoid It:

  • If the technician insists on extra services, ask for a second opinion.
  • Research whether additional services, like UV light installation, actually provide benefits.
  • Don’t feel pressured—legitimate companies will allow time for decision-making.

5. The Fake Certification Scam

Some fraudulent businesses claim to be certified by industry organizations like NADCA (National Air Duct Cleaners Association) when they are not. They use fake credentials to build trust.

How to Avoid It:

  • Verify certifications directly on NADCA’s official website.
  • Ask to see the company’s business license and insurance.
  • Look for reviews on Google, Yelp, or BBB before hiring.

 

How to Choose a Reputable Air Duct Cleaning Service

To avoid getting scammed, follow these best practices when selecting a duct cleaning company.

1. Verify Credentials

  • Choose companies certified by NADCA or another reputable organization.
  • Ensure they have liability insurance and are licensed in your state.
  • Check customer reviews on multiple platforms.

2. Get a Written Estimate Beforehand

  • A legitimate company will provide an upfront quote based on your home’s square footage and duct condition.
  • Avoid companies that only quote over the phone without an inspection.

3. Ask for Before-and-After Photos

  • A trustworthy company should be willing to show proof of their cleaning work.
  • Ask for before-and-after pictures of your actual ductwork.

4. Compare Multiple Quotes

  • Don’t settle for the cheapest option—compare pricing, service details, and reputation.
  • Avoid companies that demand full payment upfront.

 

Conclusion: Protect Yourself from Air Duct Cleaning Scams

While professional air duct cleaning can improve your home’s air quality and HVAC efficiency, scam artists are out to take advantage of uninformed homeowners. By recognizing common scams, researching reputable companies, and asking the right questions, you can avoid getting ripped off and ensure your air ducts receive proper maintenance.

Key Takeaways:

✔ Beware of low-cost bait-and-switch offers. ✔ Always verify credentials and certifications. ✔ Request written estimates before work begins. ✔ Be cautious of high-pressure upselling. ✔ Compare multiple quotes before making a

decision.

What others say


In the 5 years that I have lived in my SF valley home, I have had my AC and furnace die on me. Mike and his team gave me a great deal on new HVAC system, and 2 years later the furnace. I work in the construction industry, and confirmed quality installation and equipment. They paid attention to the little things too, which carries over in my experience. SoCal did maintenance, and the technician Dave recommended improving the duct intakes and filter system. Cannot wait for my home to be colder than a polar bear’s toenails this summer.

David Sire

I have been unbelievably impressed and overwhelmingly happy with the quality of the service provided by the team at So Cal Climate Control. From the initial estimate to the install and everything else, everyone we’ve had on this project has been so friendly, professional, and detail oriented. Highly recommend this company if you are looking for HVAC work.

Julie Matos

Overall, this was a very good experience. Customer service was great! The price was reasonable. Installation was scheduled 2 days after we purchased the HVAC system,. They installed the system in approximately 5 hours, and there was no mess. This a very professional operation

Joseph Pecot

Wonderful company! From the moment they came to give us a bid for their services to the last minute they were here. Very professional, knowledgeable, and genuine. You will not spend any money you don’t need to spend, they are honest about the work your home needs done, but also honor whatever services you’d like to have done. They respond quickly, and promptly. We had our vents/registers cleaned, old ducts removed, & new ones installed, they took care of the whole process leaving nothing behind. Charles and his crew were great! Respectful, professional, and always on time. Would highly recommend.

So Cal Climate Control was Home Adviser’s first choice, so I called and talked to dispatch. I had a technician ( Chris) at my door within 2 hours.
He was professional, courteous and their price was reasonable.

James Fisher

Mike sent his team out when our AC failed on the hottest day. It was a late Saturday afternoon and we were staring down having to wait until Monday at the earliest to get someone out. Mike immediately told me his team would be there within 90 minutes, and they showed up on a Saturday evening within the hour! Great service!
