At Lopez Air Duct Cleaning LLC, we don’t just clean ducts—we protect your Groton home from silent threats hiding in your ventilation system. Dust, pet dander, and mold spores don’t just lower air quality; they create the perfect fuel for household fires when trapped in clogged ducts near heat sources. Our technicians follow NFPA 90A standards to the letter, ensuring every vent is cleared to code so your heating system operates safely, not just efficiently. We leave no corner unchecked, from the attic to the basement, because in Groton’s older homes, hidden buildup behind walls is a common but preventable hazard.

We don’t just clean ducts—we eliminate fire hazards. Our process targets lint, dust, and debris that accumulate near heating elements, reducing the risk of electrical fires in your HVAC system. We also check for code violations like improper venting or missing fire dampers, ensuring your home meets Massachusetts safety standards.
Serving Groton since 2018, we’re fully licensed by the Commonwealth of Massachusetts and carry comprehensive liability insurance. Our technicians are trained in NFPA 90A standards for duct cleaning and fire safety, so you can trust that every job meets or exceeds local building codes.
A blocked vent or failing furnace doesn’t wait for a convenient time. That’s why we offer same-day appointments for emergency duct cleaning in Groton and surrounding towns. Whether it’s a carbon monoxide scare or a dryer vent fire risk, we’ll have a technician at your door within hours to assess and resolve the issue.
Every duct cleaning comes with a 12-month satisfaction guarantee. If you notice a recurrence of dust, mold, or airflow issues within a year, we’ll return to re-clean at no additional cost. We stand behind our work because we know a clean duct system is a safer, more efficient one.
We start with a no-obligation phone consultation to discuss your concerns—whether it’s poor airflow, strange odors, or fire safety risks. We’ll ask about your home’s age, HVAC system, and any recent issues like carbon monoxide alerts or increased energy bills. Based on your answers, we’ll provide a transparent estimate and schedule a convenient appointment.
On arrival, our technician performs a visual inspection of your ductwork, vents, and HVAC components. We check for signs of mold, water damage, or blockages and document any issues with photos. Before cleaning, we’ll shut off your HVAC system to ensure safety and prevent debris from entering your home during the process.
Using truck-mounted vacuums, rotary brushes, and HEPA filtration, we dislodge and extract debris from every inch of your duct system. Our process includes cleaning supply and return vents, main trunk lines, coils, and blower motors. We finish with a final HEPA vacuum pass to ensure no contaminants remain.
After cleaning, we test your system for proper airflow and check for any remaining issues like loose duct joints or improper venting. We provide a detailed report of what we found and fixed, along with maintenance tips to keep your ducts clean longer. We’ll also schedule a follow-up visit if needed to address any lingering concerns.
"After our 1920s home’s ducts hadn’t been cleaned in decades, we noticed musty smells and higher energy bills. Lopez Air Duct Cleaning removed years of buildup and even found a small mold colony we didn’t know about. Our furnace runs quieter now, and the air smells fresh. Highly recommend for older Groton homes!"
"I called them after a carbon monoxide alarm went off near my furnace. They arrived within hours, inspected the system, and found a cracked heat exchanger. Fixed the issue, cleaned the ducts, and gave me peace of mind. Their attention to safety is unmatched—worth every penny."
"Our dryer vent was so clogged with lint that clothes took forever to dry. After their cleaning, our dryer runs efficiently again, and I no longer worry about a fire risk. The technician even showed me how to clean the vent myself between visits. Great service!"
"We renovated our kitchen last year, and the dust from construction coated our ducts. Lopez removed every speck, and our air quality improved immediately. Their post-renovation cleaning saved us from costly HVAC repairs down the line."
