Greenwich Homeowners Expect the Best From VENTNEX
See why discerning families across Greenwich and the Gold Coast trust us with their indoor air quality.
"Our backcountry estate has four HVAC zones and VENTNEX handled all of them in a single day. The crew was professional, discreet, and incredibly thorough. They even cleaned duct runs in areas our previous service had missed entirely. Exceptional attention to detail."
"After a complete home renovation in Old Greenwich, our ducts were full of construction debris. VENTNEX scheduled us quickly and cleaned the entire system thoroughly. They protected our new finishes and left the house spotless. First-class service."
"Living near the water in Riverside means extra humidity concerns. VENTNEX cleaned our ductwork and checked for any moisture issues. They found one section with early condensation buildup and recommended a simple fix. Proactive service that prevents bigger problems."
"Our Cos Cob colonial had the original 1960s ductwork that had never been properly cleaned. VENTNEX handled the older system with care and extracted decades of buildup. The improvement in air quality and system performance was immediate. Highly impressed."
"Had an HVAC inspection done before the summer season. The technician was extremely thorough and knowledgeable, identifying a minor efficiency issue with our cooling system. The written report was detailed and professional. Only minor scheduling delay."

Frequently Asked Questions
Common questions about air duct cleaning in Greenwich
Do Greenwich's larger homes require special duct cleaning equipment?
Many Greenwich homes, particularly in backcountry and waterfront areas, have extensive multi-zone HVAC systems with long duct runs across multiple floors or wings. Our team brings commercial-grade equipment capable of handling these larger systems, including extended-reach vacuum hoses and adjustable-pressure tools. We plan each job based on the specific layout of your home, often deploying multiple technicians to ensure thorough coverage without rushing. Every zone is cleaned and tested independently to confirm optimal performance.
How does the coastal Gold Coast environment affect ductwork?
Homes in Greenwich, particularly in waterfront areas like Old Greenwich, Riverside, and Belle Haven, are exposed to salt air and elevated humidity from Long Island Sound. Salt particles can enter your HVAC system and accelerate corrosion of duct components, while humidity creates conditions favorable for mold and mildew. We recommend Gold Coast homeowners schedule duct inspections and cleanings every two to three years to stay ahead of these coastal-specific challenges and protect their HVAC investment.
What is the cost of duct cleaning for a Greenwich home?
The cost depends on the size and complexity of your home's HVAC system. A standard single-zone home typically ranges from $279 to $499, while larger homes with multiple zones or extensive ductwork may range from $499 to $899 or more. We always provide a detailed, free estimate after evaluating your specific system so there are no surprises. Our pricing includes all labor, equipment, a thorough cleaning of every register and duct run, and post-service airflow verification.
Can you schedule service around my family's privacy needs?
Absolutely. We understand that privacy is important to Greenwich homeowners, and our team operates with complete discretion. We arrive in unmarked vehicles upon request, communicate directly with you or your property manager, and can work around specific scheduling requirements. Our technicians are background-checked and trained to respect your home and property at all times. We are happy to coordinate with household staff, security personnel, or property management as needed.
Do you service homes in Cos Cob, Old Greenwich, and Riverside?
Yes, we serve all neighborhoods and villages within Greenwich including Cos Cob, Old Greenwich, Riverside, Byram, Glenville, and backcountry areas, as well as nearby Stamford and Port Chester. Our technicians are familiar with the architectural styles and HVAC configurations common throughout the area. We schedule appointments efficiently by neighborhood and can often accommodate same-day or next-day requests depending on availability.
Do you offer recurring service plans for Greenwich homeowners?
Yes, we offer annual and semi-annual service plans that include scheduled duct cleaning, dryer vent service, and HVAC inspections at preferred pricing. Many Greenwich families enroll in our premium maintenance plan, which ensures their air quality is proactively managed throughout the year. We maintain detailed service records and coordinate scheduling in advance so your home is always receiving timely attention. Contact us to discuss a plan tailored to your property's specific needs.
