FAQs
Why is duct cleaning important for my home in Townsend?
Townsend’s mix of hot, humid summers and chilly winters means your HVAC system runs nearly year-round, circulating dust, pollen, dander, and even moisture through the ductwork. Over time those contaminants accumulate on the interior of the ducts, where they can be blown back into your living spaces every time the furnace or air conditioner cycles on. Professional duct cleaning removes that buildup, helping to reduce allergy and asthma triggers, eliminate musty or smoky odors, and maintain healthy indoor air quality for your family.
How often should I schedule professional duct cleaning?
For most homes in Townsend, the National Air Duct Cleaners Association (NADCA) recommends a full cleaning every 3–5 years. However, you may benefit from more frequent service—every 2–3 years—if your household includes pets that shed, smokers, recent renovations, or allergy-sensitive occupants. If a moisture problem or a pest infestation is discovered, an immediate cleaning plus corrective action is strongly advised.
What signs indicate my HVAC ducts need to be cleaned?
Common warning signs include: 1) visible dust puffs or debris coming from registers when the system kicks on, 2) a persistent musty or stale odor in certain rooms, 3) excessive dust buildup on furniture shortly after cleaning, 4) unexplained allergy or respiratory flare-ups among occupants, 5) evidence of insects, rodents, or mold inside duct runs, and 6) noticeably reduced airflow from some vents. If you notice one or more of these issues, a thorough inspection followed by cleaning is recommended.
What does the duct cleaning process involve and how long does it take?
Our NADCA-certified technicians first protect your floors and furniture, then access the supply and return sides of the duct system. Using a powerful negative-air vacuum, we place the entire system under suction while high-pressure air whips dislodge debris from the walls of each branch line. Registers, grilles, blower components, and the evaporator coil are carefully cleaned as well. A typical single-family home in Townsend requires 3–5 hours, depending on square footage, the number of vents, and the degree of buildup. Larger homes or neglected systems can take longer.
Will duct cleaning improve my HVAC system’s efficiency and lower energy bills?
Yes—dust and debris restrict airflow, forcing your furnace or air conditioner to work harder to push conditioned air throughout the home. By restoring unobstructed airflow, duct cleaning can reduce fan motor strain and help your system reach the thermostat set point more quickly. Studies conducted by the U.S. Department of Energy estimate that clean HVAC components can deliver energy savings of 5 –15 percent, which translates into lower monthly utility costs and extended equipment life.
Is duct cleaning safe for my family and pets, and do I need to leave the house during service?
We use HEPA-filtered, negative-pressure equipment that captures 99.97 percent of dislodged particles before they can enter your living spaces. Non-toxic, EPA-approved sanitizers are available for addressing microbial growth and are safe once dry—usually within 30 minutes. You and your pets can remain in the home; however, we recommend staying clear of work areas to avoid tripping over hoses and cords. For individuals with severe respiratory conditions, temporarily relocating to a different room or outside the home during active cleaning may provide added comfort.
