Frequently Asked Questions
Straightforward answers to the most common questions about our air duct cleaning, dryer vent maintenance, and local service coverage.
Duct Cleaning Methods & Safety
Q:What cleaning method does Duct Cleaning Heroes use?
We use source-removal mechanical agitation combined with high-volume negative air pressure vacuum containment. Our machines pull vacuum pressure on the central trunks while flexible air whips and rotary brushes sweep debris from individual branch runs into the collector.
Q:Will duct cleaning blow dust and soot all over my house?
No. Because our vacuum units maintain continuous negative draft inside the ductwork, any particles dislodged by brushes are drawn inward toward the collection equipment rather than escaping into your finished rooms.
Q:Do you sanitize or spray chemicals inside the ductwork?
We prioritize mechanical source removal—physically extracting particulate matter. If an antimicrobial fogging treatment is requested for specific odor or water-intrusion concerns, we discuss EPA-registered options beforehand. We never use unverified chemical sprays.
Pricing & Service Scope
Q:Why don't you advertise a flat $79 whole-house coupon?
Ultra-cheap flat-rate promotions are almost universally bait-and-switch ploys in this industry. A thorough duct cleaning requires 2.5 to 4 hours of labor, heavy specialized equipment, and skilled technicians. We provide honest upfront pricing based on your actual furnace count and register volume.
Q:What factors affect the price of air duct cleaning?
Key variables include the number of HVAC heating/cooling units, total supply and return vent counts, property square footage, and duct access (e.g. standard basements vs tight crawlspaces). Contact us for a prompt, transparent quote.
Q:Can I bundle dryer vent cleaning with my air duct appointment?
Yes. Bundling both services during a single technician visit is our most cost-effective option and ensures complete airflow safety for your home.
Service Area & Booking Logistics
Q:What is your coverage area?
We are based in Lawrence, Massachusetts, and service an approximate 60-mile radius across Essex County, Middlesex County, and Southern New Hampshire communities including Salem, Pelham, Windham, and Derry.
Q:How long does an appointment usually take?
For an average single-family home with one furnace system, appointments typically last between 2.5 and 4 hours. Commercial buildings and multi-zone homes take longer depending on blueprint scope.
