Why Hire a NADCA-Certified HVAC Cleaning Company

Serving Connecticut, Massachusetts & Rhode Island

There are differences among companies when it comes to air duct and HVAC cleaning. Anyone can claim they can "clean ducts," but very few uphold the performance, safety, and quality standards that genuinely impact air quality and system efficiency. You might wonder how experienced these companies are and whether they follow any real industry standards.

Hiring an expert who is NADCA-certified is important for this reason.

For more than two decades, Mechanical Hygiene Services (MHS) has been enhancing indoor air systems across Connecticut, Massachusetts, and Rhode Island, working with hospitals, schools, manufacturing plants, cannabis operations, and commercial buildings. The National Air Duct Cleaners Association (NADCA) is our proud association, and we always adhere to the highest standards for HVAC inspection, cleaning, and restoration.

When you hire a NADCA-certified company, you’re working with people who know the science behind clean air systems and follow clear rules for safety and quality.

At Mechanical Hygiene Services (MHS), we are proud to be a part of that trustworthy network. Being NADCA-certified is more than just a badge; our staff has undergone training, testing, and ongoing education to stay current with the latest HVAC cleaning regulations. All of our projects adhere to the ACR Standard of NADCA, which is also used by hospitals, labs, and large commercial facilities across the country.

Why NADCA Certification Matters

Choosing a business like MHS that is NADCA-certified shields you against the increasing number of duct cleaning scams. These businesses speed through the task, claim a low fee, and leave more dust behind than they remove.

How to Verify a NADCA Member

You should be cautious about who you allow inside your building when you hire a firm to clean your HVAC system or air ducts. Although anyone can say they "follow NADCA standards," this does not always imply that they are competent or certified. It just takes a few minutes to confirm their qualifications, and doing so can help you avoid subpar work and future expenses.

A legitimate NADCA-certified company should be able to show proof of:

01
Current NADCA membership — with a valid certification number.
02
At least one Certified Air Systems Cleaning Specialist (ASCS) on staff.
03
Active general liability insurance to protect your property and workers.
To find out if a business is listed as a verified member, you may also go to nadca.com and utilize the Find a Professional function.
