Okay, so you've decided that your air ducts need cleaning. The yellow pages are loaded with companies, and a Google search turned up scores of sites that mention the service. How can you wade through all this information and find a company you can trust? Here are a few tips.
Look for NADCA Certification
The National Air Duct Cleaning Association (NADCA) is a professional organization that offers certification to air duct cleaning specialists who meet industry standards. Three NADCA certifications are available:
· ASCS - Air Systems Cleaning Specialist (basic certification),
· CVI - Certified Ventilation Inspector (oriented toward commercial jobs), and
· VSMR - Ventilation Systems Mold Remediator (for jobs involving mold).
If a company has taken the time to get any or all of the certifications above, that company has demonstrated a commitment to meeting industry standards and is probably a cut above competitors not certified by the NADCA.
Insist on Experience
Air duct cleaning companies rely heavily on word of mouth for new and returning customers. So, it stands to reason that a company that's been in business for several years has done work that customers recommend. Look for companies that have been working in your community for 10 or more years. And, feel free to ask for references when you call.
Check Angie's List for Reviews
Angie's List ( www.angieslist.com ) is an independent source for reviews from homeowners in your community. If you want to hear what customers are really saying about the company that cleaned their ducts, you'll get an unfiltered idea here.
Ask About the Process, Equipment, and Insurance
Don't hesitate to ask questions about the cleaning process and equipment. A reputable company will have experienced professionals who can answer these questions and more. In general, duct cleaning begins with an inspection, possibly including a test of your indoor air, to get an overall idea of how the air ducts may be affecting air quality. If the professional finds a problem, he can clean your vents and ducts with special brushes, a large vacumming system (truck mount or a gas power portable unit), and other dirt-loosening equipment. Large hoses suck the loosened dirt and grime out of your home and into a secure container for safe disposal. He also can come up with a plan of action to help prevent future air quality problems.
Also, ask about insurance, and refuse to hire an uninsured company. Any reputable company should carry insurance for your and the workers' protection.
