The EPA's official position is that cleaning should be event-driven. You should schedule a cleaning if you see visible mold, signs of pest infestation, or excessive dust and debris clogging the system, rather than adhering to a strict, arbitrary schedule.

What the Pros Say
"We generally tell homeowners to consider it every 3 to 5 years. If you have pets that shed a lot or family members with bad allergies, you'll see a noticeable difference. It's about preventative maintenance as much as it is about cleanliness."

Mike Johnson
HVAC Technician, 15 years"The most important factor is what's actually going on in the home. Just did a major renovation? Get them cleaned. See dust puffing out of your vents? Time for a cleaning. A calendar date is a guideline, but visible signs are a call to action."

Sarah Chen
Service Manager, Clean Air Solutions"A proper cleaning isn't just a vacuum in the vent. We use high-powered negative air pressure systems to contain debris and specialized tools to agitate and remove buildup from the entire system, including the coils and blower motor. Anything less is a waste of money."
C
Carlos Rodriguez
Master Technician & NADCA Certified Inspector"Consumers need to be wary of the '$99 whole-house special.' Those are often scams. A legitimate, certified company will charge a fair price—typically $300-$500—because the process is labor-intensive and requires expensive equipment to do safely and effectively."
