"The technician that cleaned my ductwork had a lot of work to do. Milan had asked me as he was leaving how long had it been since I had the ducts cleaned. I couldn’t recall, then realized it was a long time ago. 30 years! As a new homeowner I had zero experience so I was relying on my husband. He died 5 years after we bought this house and being clueless about the care & upkeep on it. I neglected pretty much everything. Lowes the Company offered the same exact cleaning as 2 other companies that gave me estimates over $1,000. Lowes has 3 flat rates to choose from, I chose the $398 special and that’s exactly what I paid. Great Company with Great prices!"

FAQs for air ducts & vents cleaning service projects in Portsmouth, NH

The Environmental Protection Agency (EPA) states that air duct cleaning is not required unless visible issues such as mold buildup, rodent droppings, or excessive dust are present. When such conditions exist, cleaning becomes essential to protect indoor air quality and maintain HVAC efficiency. This approach minimizes potential health risks and extends the system’s life.

Air ducts must be cleaned every three to five years as required by NADCA to preserve system efficiency and indoor air quality. The EPA insists that cleaning is necessary only when significant issues such as mold, pest infestations, or heavy dust accumulation are evident. Annual inspections by a certified professional promptly address any emerging concerns.

The ideal seasons for air duct cleaning are spring and fall. Cleaning during these periods prepares your HVAC system for the demands of both winter heating and summer cooling. These seasons provide moderate weather conditions that enable efficient service completion while minimizing disruption, ensuring your system performs at its peak.

Professional air duct cleaning takes a fixed duration of two to five hours, depending on the home’s size and the complexity of the duct system. Smaller residences with standard ductwork complete the service in two hours, while larger homes with extensive ducts require up to five hours. Additional repairs may extend this duration.

To prepare for professional air duct cleaning, ensure all vents are unobstructed by moving nearby furniture and clearing pathways. Secure any pets in a safe area and confirm that your HVAC system units are easily accessible for technician inspection. Proper preparation contributes to a higher quality service outcome and prevents delays, allowing the cleaning process to proceed efficiently.
