Avoid scams in duct cleaning services with our guide to find a trustworthy provider.
Air duct cleaning services are often promoted as a quick way to improve indoor air quality, but not all offers are as honest as they appear. Maybe you’ve seen ads in local papers – companies you’ve never heard of advertising duct cleaning services for unimaginably low prices – $49.95 for your whole house! If these prices sound too good to be true, it’s usually because they are. You sign up for service, and an “air conditioning tech” shows up, spends little time doing actual work, and then claims you need at least $500 worth of additional service.
Wait…what?? It’s true – there have been multiple hidden camera news stories about these unscrupulous dealers and their methods. Companies like these prey on the elderly and unsuspecting homeowners, trying to drain as much money as possible. The worst part is, they too often get away with it.
So how do you avoid these air duct cleaning scammers? The easiest way to protect yourself is to first think about exactly why you need duct cleaning services. In most homes, you should only need air duct cleaning once every couple of years, or annually if anyone in your home suffers from bad allergies.
A reputable duct cleaning service may suggest biocides or chemical treatments to get rid of mold or bacteria growth. Before you agree, make sure the technician explains both the pros and cons. Also, look for companies that charge a flat rate for the job instead of billing by the hour.
If your ducts are clogged or airflow is restricted, it might be time to pair duct cleaning with professional AC repair or new system installation to ensure long-term efficiency.
You should only need duct cleaning services if:
Reliable duct cleaning companies follow best practices to ensure your system is properly cleaned:
Pairing this service with seasonal AC maintenance ensures long-term air quality and system performance.
Air duct cleaning is not a magic solution that will eliminate all indoor air quality problems, but it can be important when certain conditions exist. Choosing a reputable company ensures the work is done safely and effectively, without hidden fees or unnecessary upsells. When in doubt, research your provider, ask for references, and make sure they follow industry best practices before scheduling duct cleaning services.
In most cases, air ducts only need to be cleaned every 2–3 years. However, if you notice visible mold, vermin infestations, or heavy dust buildup, you may need cleaning sooner. Homeowners with pets or allergy sufferers in the household may benefit from annual duct inspections to determine if cleaning is needed.
Yes, but results vary. Duct cleaning removes built-up dust, debris, and potential allergens, which can improve airflow and indoor air quality. However, it’s not a cure-all. Combining duct cleaning with regular HVAC maintenance and filter changes provides the best long-term results.
Red flags include extremely low advertised prices, vague promises of health benefits, and technicians claiming to be “EPA-certified.” Another warning sign is upselling—when a company tries to charge hundreds of dollars more once they arrive. Trustworthy companies provide clear estimates upfront.
Yes, if done correctly. Professional companies use soft-bristled brushes and HEPA vacuums to avoid damaging fiberglass duct board or fiberglass-lined sheet metal ducts. This ensures your ducts stay intact while being thoroughly cleaned.
Yes. While duct cleaning alone doesn’t replace the need for AC repair or upgrades, removing clogs and debris allows air to flow more freely. This reduces strain on your system, helping it run more efficiently and last longer.
