Read more →That musty odor is likely mold or mildew growing in your ducts, thriving on summer humidity and organic dust trapped inside. When heat circulates for the first time, it stirs up these spores, sending them straight into your living spaces. Delgado’s duct cleaning removes the source before it spreads, and we sanitize with EPA-approved solutions to prevent regrowth.
Salt air corrodes metal ductwork faster than inland homes, especially if your vents are near the coast or exposed to ocean breezes. Over time, this corrosion creates tiny holes that let in dust, pests, and even water during Nor’easters. Our cleaning includes a corrosion check and recommendations for protective coatings or replacements.
Watch for uneven airflow, longer heating times, or a whistling sound when your furnace kicks on—classic signs of blockages. Also, check your vents for visible dust or debris around the registers. If you’re seeing more dust on furniture after cleaning, it’s time for a professional inspection.
Absolutely. Winter forces your HVAC system to recirculate the same air for months, and dirty ducts act like a petri dish for allergens. If you’re sneezing or congested indoors while the snow flies, your ducts are likely the culprit. We remove 99% of allergens, including pet dander and pollen tracked in from summer.
A blocked or dirty duct system can’t handle the sudden pressure drop from a powerful storm, risking cracks or disconnections in your vents. Moisture from the storm can also seep into ducts, fueling mold growth that spreads when the power comes back on. Pre-storm cleaning prevents costly repairs and health hazards.
Yes. Restricted airflow forces your furnace to run longer and hotter, wearing out components and spiking energy bills. In older Cohasset homes with original ductwork, this strain can lead to cracks or even carbon monoxide leaks. Clean ducts improve efficiency by up to 40% and extend your system’s lifespan.
Most clients report fresher air within 24 hours, with reduced dust and odors noticeable almost immediately. For severe cases, like heavy mold or pet dander buildup, it may take a week for your body to fully adjust. We recommend cleaning ducts every 3–5 years, or after major home renovations.
Book by late September or early October to beat the rush. Cohasset homeowners who wait until after the first snow often face waitlists or emergency fees. Our team prioritizes pre-winter cleanings, ensuring your ducts are ready before the holidays and winter storms hit.
