FAQs
What is negative-pressure containment duct cleaning and how does it work?
Negative-pressure containment is an advanced duct-cleaning method that seals your HVAC system, then places the entire duct network under a controlled vacuum using a high-capacity HEPA-filtered machine. As our rotary brushes and air whips dislodge dust, mold, and debris, the negative pressure pulls all contaminants directly into the sealed collection unit, preventing any particles from escaping into your living or work space. The result is a thorough cleaning with zero cross-contamination.
Why is negative-pressure containment especially valuable for homes and businesses in Birchwood?
Birchwood’s seasonal humidity and long heating season create ideal conditions for dust, pollen, and microbial growth inside ducts. Traditional cleaning can release these pollutants back into the air. Negative-pressure containment captures them at the source, safeguarding indoor air quality during and after the service. It’s also recommended for Birchwood’s many lake-adjacent properties, where higher moisture levels can accelerate mold buildup.
How often should I schedule a negative-pressure containment duct cleaning?
For most Birchwood residences, we recommend a full negative-pressure cleaning every 3–5 years. Commercial facilities, rental cabins, or homes with pets, smokers, or allergy sufferers may benefit from service every 2–3 years. After major renovations or wildfire smoke events, an immediate cleaning is advisable. We offer complimentary inspections to determine the right interval for your property.
Will the cleaning process disrupt my daily routine or harm occupants and pets?
Our containment equipment is designed for quiet, low-vibration operation. While we isolate each register, your HVAC system is temporarily offline, but you can remain in the building. The HEPA-filtered vacuum prevents dust release, making the process safe for children, pets, and sensitive electronics. We lay protective floor coverings and clean up thoroughly so you can resume normal activities as soon as we finish.
How long does a typical service take and what does it cost?
A standard Birchwood single-family home (10–15 vents) usually takes 3–4 hours. Larger homes, commercial sites, or systems with heavy contamination may extend to a full day. Residential pricing starts at $449, which includes supply and return ducts, one furnace, and antimicrobial fogging. We provide firm, written quotes after an on-site assessment, and offer seasonal discounts for Birchwood residents.
Are your technicians certified and do you follow industry and local regulations?
Yes. Our lead technicians hold NADCA Air Systems Cleaning Specialist (ASCS) certification and are trained in OSHA containment protocols. We are licensed, bonded, and insured in Wisconsin, and comply with Birchwood’s local environmental ordinances for debris disposal. All equipment meets EPA and National Air Filtration Association (NAFA) standards, ensuring you receive safe, code-compliant service.
