Ensuring your ducts are properly cleaned by a reputable company requires doing your research upfront. Here are key questions to ask to determine a duct cleaner’s competence, experience and trustworthiness.
- How long have you been in business? Request documentation of the company’s establishment date and check with the Better Business Bureau for complaint history.
- What credentials and certifications do you have? Legitimate companies maintain certification by NAIMA (the North American Insulation Manufacturers Association) or the NADCA (National Air Duct Cleaners Association).
- Do you follow NADCA standards? Ask if the company follows the rigorous NADCA procedures and guidelines for thorough duct cleaning.
- Will you seal my ducts after service? Resealing ducts after cleaning reduces dust accumulation and improves system efficiency.
- Furthermore, what equipment will you use? High-efficiency vacuums and motorized cleaning tools indicate professional-grade work.
- Do you isolate different parts of the duct system? Isolating work areas prevents cross-contamination and spread of debris.
- What cleaning agents will you apply? Look for agents specifically designed for ducts, not just household cleaners.
- In addition, can you provide references? Check the references to verify satisfied customers and quality work.
- How long will the cleaning take? Avoid companies promising “quick cleanings” that may miss some ducts.
- Additionally, what is your estimated fee? Compare detailed, itemized estimates from multiple companies.
- Will I receive any air quality testing before and after? Such testing provides an objective metric of the cleaning’s effectiveness.
- Finally, is the crew EPA certified in removal of asbestos? Ask especially for older homes where asbestos may be present.
In summary, these key questions will help determine a duct cleaning company‘s competence, experience, trustworthiness and ability to do the job right. Do your research upfront by asking companies these important questions – plus any others specific to your situation. Thoroughly vetting duct cleaning professionals before hiring will ensure you get a comprehensive job performed by true experts.
