What the Pros Say
"Don't clean your ducts just because it's been a few years. Clean them when there's a reason. After a renovation, if you see mold on the registers, or if there's a pest issue—that's when a professional cleaning makes a real difference."
M
Mike Johnson
HVAC Technician, 15 years"The biggest mistake homeowners make is hiring the company with the $99 special. A proper cleaning requires powerful, specialized equipment. Always ask for proof of NADCA certification to avoid scams and ensure the job is done right."
S
Sarah Chen
Service Manager"Cleaning is only half the battle. We find that up to 30% of air is lost through leaks in the average home's ductwork. Sealing those leaks provides a much bigger and more consistent return on investment than cleaning alone."
C
Carlos Rodriguez
Master Technician"Think of duct maintenance as protecting your largest home appliance. A clean, well-sealed system runs more efficiently, lasts longer, and provides better comfort. It's an investment in both your property and your family's well-being."
