Questions to Ask a Air Duct Cleaning in Glendale
“Are you NADCA certified, and do you follow the NADCA ACR Standard?”
NADCA (National Air Duct Cleaners Association) certification means the company follows established cleaning standards and uses proper equipment. Many companies advertise duct cleaning without this baseline qualification.
“What equipment do you use — truck-mounted or portable?”
Truck-mounted systems provide 10,000+ CFM of suction and create true negative pressure through your duct system. Portable units are inadequate for whole-house cleaning. This single question separates legitimate companies from scammers.
“Can you show me the inside of my ducts before and after?”
Reputable companies use duct cameras and will happily show you the condition of your ducts before work begins. This also protects you from paying for cleaning you might not actually need.
Red Flags When Hiring
- ✖Advertises a whole-house duct cleaning for under $100 — this is universally a scam or bait-and-switch
- ✖Cannot explain their cleaning process step-by-step or uses vague terms like 'sanitizing treatment'
- ✖Pushes chemical treatments, sealants, or UV light systems as mandatory add-ons during the initial cleaning
- ✖Uses portable equipment only — no truck-mounted vacuum system
Safety Tips
- Beware of $29 or $49 whole-house duct cleaning offers — these are bait-and-switch scams that upsell unnecessary treatments. Legitimate duct cleaning costs $300–$700
- Never allow a duct cleaner to apply chemical sealants, biocides, or 'encapsulants' inside your ducts unless you have documented mold growth confirmed by testing — these chemicals can off-gas into your living space
- Dryer vent cleaning is not the same as duct cleaning. Clogged dryer vents are a fire hazard — the CPSC estimates 2,900 dryer fires per year from lint buildup
