The overwhelming industry consensus is that post-construction duct cleaning is an essential, non-negotiable step. Fine particulates from construction, like drywall dust and sawdust, are highly abrasive to new HVAC systems and pose significant risks to indoor air quality. Skipping this service can lead to costly equipment damage and health issues.

What the Pros Say
"You wouldn't believe what we pull out of ducts after a remodel. It's not just dust; it's drywall chunks, screws, sawdust, and insulation fibers. Running a new furnace or AC with that stuff inside is like throwing sand into a brand new engine."

Mike Johnson
HVAC Technician, 15 years"The finest dust, the stuff you can't even see, is the most dangerous. Drywall dust is particularly bad for respiratory health. A post-construction cleaning is the single most important thing you can do for your home's air quality before you move in."

Sarah Chen
Indoor Air Quality Specialist"We install these high-efficiency systems, and their longevity depends on a clean environment. Debris clogs the evaporator coil and blower wheel, causing strain, reducing airflow, and leading to premature failure. Cleaning is cheap insurance for a multi-thousand dollar investment."

Carlos Rodriguez
Master Technician & Installer"As a business owner, I tell my clients this: factor it into your budget from the start. A few hundred dollars for a proper cleaning prevents warranty-voiding damage and ensures the system we just installed works perfectly. It's the final, critical step of a quality construction project."
