Lexington Homeowners Rate Us Five Stars
From colonial restorations to newer builds, see why Lexington residents choose VENTNEX for their air duct needs.
"Our 1780s home near the Battle Green has a retrofitted forced-air system that most companies refuse to touch. VENTNEX took the time to map out the duct layout and cleaned everything without a single issue. The air quality improvement was immediate."
"We noticed musty odors whenever the heat kicked on in our Follen Hill colonial. VENTNEX found years of accumulated dust and debris deep in our trunk lines. After the cleaning, the smell is completely gone and the heat distributes much more evenly."
"Scheduled a dryer vent cleaning after our dryer started overheating and shutting off mid-cycle. The technician found a dense lint blockage about twelve feet into the vent run. He cleared it completely and our dryer has worked perfectly ever since."
"Solid service overall. The crew was on time and thorough with our duct cleaning. They found a small gap in one of our branch lines and sealed it during the visit. Minor scheduling hiccup getting the appointment, but the work itself was first-rate."
"As a family with three young children and two dogs, indoor air quality is a major concern for us. VENTNEX removed a remarkable amount of pet dander and dust from our system. Everyone in the house is sleeping better, and my son's nighttime coughing has stopped."
"Had the HVAC inspection done before summer and the technician identified that our AC evaporator coil was nearly blocked. He cleaned it and checked the entire duct system. Our air conditioning ran better this summer than it has in years. Very thorough work."
"We just bought our first home in Lexington and wanted the ducts cleaned before moving the baby in. VENTNEX accommodated our tight timeline and did a beautiful job. They even put down protective coverings on all the hardwood floors without us asking."
"Our ranch-style home on Marrett Road has a single-zone system that was blowing weaker and weaker. After VENTNEX cleaned the ducts, airflow is noticeably stronger from every register. The technician also recommended a filter upgrade that has made a real difference."
"Good experience with the dryer vent service. The technician was knowledgeable and explained the fire risks associated with our long vent run through the basement ceiling. Everything was cleaned up neatly when he finished. Booking was easy through their website."
"Had VENTNEX clean the ducts in our 1960s raised ranch before heating season. They pulled out an unbelievable amount of dust, insulation fragments, and even some old construction debris from a renovation done before we owned the house. Furnace is running smoother now."
"The team was professional from start to finish. They arrived in a clean, well-marked van and wore boot covers inside. Our home on Turning Mill has complicated ductwork in the basement, but they navigated it all. Heating efficiency has noticeably improved."
"Called for a heating system checkup when our furnace started cycling on and off too frequently. The technician diagnosed a partially blocked return duct that was causing the system to overheat and shut down. After cleaning and adjusting, it runs perfectly. Saved us from an unnecessary furnace replacement."

Frequently Asked Questions
Common questions about air duct cleaning in Lexington
Can you work with the retrofitted HVAC systems common in Lexington's older homes?
Yes, this is one of our specialties. Many Lexington homes originally had radiator or baseboard heating and later had forced-air systems added. These retrofits often involve unconventional duct routing through closets, between floor joists, and around structural elements. Our technicians carry flexible tools designed to navigate these tight, angled pathways. We take extra care to avoid stressing connections in older systems and always inspect for any pre-existing damage before we begin cleaning.
How long does a typical duct cleaning take for a Lexington colonial?
For a standard three- to four-bedroom colonial, which is very common in Lexington, a full duct cleaning typically takes between three and four hours. Larger homes or those with multiple HVAC zones may take longer. We never rush through a job because thorough cleaning requires careful attention to every supply vent, return register, and trunk line. We will give you an accurate time estimate during your free inspection so you can plan your day accordingly.
Is mold a concern in Lexington home duct systems?
Mold can develop in any home where moisture enters the ductwork, and Lexington's humid summers combined with older basements create conditions where this is possible. We check for visible signs of mold growth during every duct cleaning and can perform additional testing if anything looks suspicious. If mold is present, we recommend professional remediation before completing the duct cleaning to ensure the problem is addressed at its source rather than just cleaned superficially.
Should I have my ducts cleaned after a home renovation in Lexington?
Absolutely. Home renovations generate enormous amounts of fine dust, drywall particles, sawdust, and construction debris that settles deep inside your duct system. Even if the work area was sealed off, these particles travel through the air and into your HVAC returns. We strongly recommend a thorough duct cleaning after any significant renovation project. Many Lexington homeowners schedule us for the week after their contractor finishes to ensure their newly updated home also has freshly cleaned air.
Do you service Lexington homes with oil-fired heating systems?
Yes, we service homes with all types of heating systems, including the oil-fired furnaces still found in many older Lexington properties. Oil heat can produce a fine soot that gradually accumulates inside ductwork over the years, reducing air quality and leaving a subtle odor. Our cleaning process removes this buildup effectively. We also inspect the ductwork near the furnace for any signs of soot leakage that could indicate a combustion issue requiring attention from your heating technician.
What areas around Lexington do you also serve?
In addition to all of Lexington, we serve the neighboring communities of Arlington, Bedford, Burlington, Winchester, Woburn, and Concord. Our technicians are based locally and know these towns well, which means short travel times and the ability to schedule appointments conveniently. Whether you are near Lexington center or out toward the Bedford line, we provide the same thorough service and free estimates to every customer in our coverage area.
