A few simple, safe steps before your Cohasset air duct cleaning can save time and money. Learn what you can handle yourself and when to call Delgado Air Duct Cleaning LLC for the rest.
Clear the area around vents and returns in Cohasset homes
Walk through your Cohasset home and clear at least 3 feet of space around every supply vent and return air grille. Move furniture, rugs, and decor that might block access. In older homes near Cohasset Center, this is especially important because vents may be tucked behind built-ins or under low ceilings. If you have pets, keep them in a separate room during cleaning to reduce stress and dust circulation. This small effort helps technicians work faster and protects your belongings from accidental damage.
Turn off your HVAC system before the technician arrives
Locate your thermostat and switch the system to OFF. If you have a whole-house fan or ERV/HRV unit, turn those off as well. In Cohasset, where coastal winds can stir up outdoor allergens, turning off the system prevents dust and debris from recirculating during cleaning. If you’re unsure how to shut off your system safely, check your owner’s manual or contact us for guidance. Never attempt to remove or clean internal duct components yourself—leave that to licensed professionals.
Check for warning signs that need a pro’s attention
Before your appointment, look for signs that your ducts need more than routine cleaning. If you notice black dust around vents, moldy odors when the system runs, or unexplained respiratory issues that worsen indoors, these could indicate serious problems like moisture intrusion or microbial growth. In Cohasset’s humid climate, ducts near bathrooms or kitchens are especially vulnerable. If you see water stains, condensation, or feel inconsistent airflow, stop DIY efforts and contact us immediately—these issues require professional inspection and remediation.
What you should NEVER DIY in your Cohasset ducts
Never use shop vacuums, wire brushes, or chemical cleaners inside ducts. These can damage ductwork, dislodge mold spores, or leave harmful residues that worsen indoor air quality. In older Cohasset homes with fragile ductwork, even minor DIY attempts can void warranties or create costly leaks. Also avoid sealing ducts with duct tape—it degrades over time. For safe, effective cleaning, trust licensed technicians who use HEPA vacuums and EPA-approved methods. Learn more about our process.

Bonus: Prep for peak season in Cohasset
Schedule your air duct cleaning in late fall, before heating season ramps up. Cohasset’s damp winters can introduce moisture into ducts, promoting mold growth. After cleaning, consider adding a germicidal UV light to your HVAC system to keep air cleaner year-round.

Frequently Asked Questions
Why do my Cohasset air vents smell musty when it rains?
Musty odors during rain often point to moisture in your ducts, especially in older Cohasset homes near the shore. This can feed mold growth on duct liners or insulation. A professional inspection is needed to identify the source and prevent further contamination. Call us today to schedule a duct and HVAC system evaluation.
Can I clean my Cohasset air ducts myself with a shop vacuum?
No. Shop vacuums lack HEPA filtration and can spread dust and allergens throughout your home. In Cohasset, where pollen counts are high, improper DIY cleaning can worsen indoor air quality. Leave duct cleaning to licensed professionals with the right equipment. See our service details.
What does it mean if my Cohasset thermostat fan runs nonstop after duct cleaning?
A continuous fan cycle after cleaning may signal a pressure imbalance or a dirty blower wheel that wasn’t fully addressed. In Cohasset homes with zoned systems, this is more common. It’s not normal and requires a professional tune-up. Contact us to diagnose and resolve the issue safely.
