Frequently Asked Questions
General Questions
Q: Why should I have my air ducts cleaned?
A: Over time, dust, allergens, pet dander, and other debris build up inside your ducts. Cleaning helps improve indoor air quality, reduce allergens, and keep your HVAC system running more efficiently.
Q: How often should I get my air ducts cleaned?
A: Most homes benefit from duct cleaning every 3–5 years. Homes with pets, smokers, or residents with allergies may need it more frequently.
Q: Do you also clean dryer vents?
A: Yes! In fact, we highly recommend it. A clogged dryer vent is a major fire hazard and can also make your dryer less efficient, leading to longer drying times and higher energy bills.
Q: How do I know if my air ducts need cleaning?
A: Signs include:
Dust blowing from vents
Mold or mildew smell in the HVAC system
Visible dust around vent covers
Increased allergy symptoms indoors
Rising energy bills
Process & Safety

A: We use professional-grade equipment to loosen and remove debris from your ductwork. Then we use a powerful vacuum system to extract dust, dirt, and contaminants, leaving your ducts clean and your air healthier.
Q: Is duct cleaning safe for my HVAC system?
A: Absolutely. Our equipment is designed for residential and commercial HVAC systems. We take great care to protect your system and ensure no damage.

Health & Efficiency
Q: Will duct cleaning help with allergies or asthma?
A: While duct cleaning is not a cure, it can significantly reduce dust, pollen, mold spores, and pet dander in your home, which often helps those with respiratory issues.
Q: Can duct cleaning lower my energy bills?
A: Yes. A clean HVAC system doesn’t have to work as hard to push air through your ducts, which means better efficiency and potential savings on energy costs.
Q: Why is dryer vent cleaning important?
A: Lint buildup in dryer vents is one of the leading causes of house fires. Regular cleaning improves safety, shortens drying times, and extends the life of your dryer.
Scheduling & Pricing
Q: How much does duct cleaning cost?
A: Pricing varies by home size, number of vents, and system complexity. We provide free estimates and upfront pricing before starting any job.
