Most homeowners do not think much about their air ducts until there is a noticeable problem. In Charleston, however, the combination of humidity, moisture, and year-round HVAC use can make duct systems more vulnerable to mold, mildew, and accumulated debris.
The challenge is that air duct cleaning companies in Charleston do not all provide the same level of service. Some offer comprehensive inspections and documented cleaning processes, while others may provide little more than surface-level cleaning.
To narrow down the options, we reviewed local providers based on service depth, credentials, customer feedback, and their ability to demonstrate consistent results. The four companies below stood out during that process.
Each provider was researched using publicly available information from customer review platforms, service directories, company websites, and industry sources.
The focus was placed on:
Star ratings were considered, but they were not used as the only deciding factor.
Choosing the wrong duct cleaning company can mean paying for a service that does not address the actual contamination inside the system.
In some cases, inadequate cleaning can leave behind debris, microbial growth, or sections of ductwork that were never properly treated.
Charleston's humid subtropical climate makes this especially relevant. Moisture can contribute to mold and mildew development inside older HVAC systems, meaning a basic surface cleaning may not always be enough.
The stronger companies tend to follow a process that customers can verify. Depending on the provider, this may include:
That additional evidence can make it much easier to understand whether the service actually improved the condition of the system.

Best for: Homeowners and businesses looking for duct cleaning combined with broader indoor air quality services
R&E Home Solutions provides a wider range of services than standard duct cleaning alone, including:
The company works with both residential and commercial properties throughout South Carolina.
It also uses organic products during the cleaning process, which may be relevant for households concerned about stronger chemical treatments.
Another practical advantage is 24/7 emergency availability.
R&E Home Solutions combines local experience with recognized industry credentials.
The family-owned company has operated in the area for more than a decade and holds NADCA certification. It also has more than 500 five-star reviews.
That combination of certification, longevity, and substantial customer feedback helps distinguish it in a market where service quality can vary significantly.
Customer feedback regularly mentions fast response times, professional technicians, and clear communication.
Many customers also appreciate that technicians explain what they found inside the system and why particular work may be necessary rather than simply completing the cleaning without context.
Best for: Homeowners who want duct-related services from a broader residential HVAC company
Coastal Carolina Comfort primarily operates as a full-service heating and cooling company.
Its services include:
The company also provides 24/7 emergency service and works with NATE-certified technicians.
For larger HVAC projects, it offers financing options, including 0% interest financing for 24 months.
Coastal Carolina Comfort's strength is less about being a specialized duct-cleaning-only company and more about its broader HVAC knowledge.
That can be useful for homeowners who suspect that an air quality or duct issue may be connected to the condition of the HVAC system itself.
The company's direct owner involvement is also frequently mentioned as a differentiating factor.
Customers commonly highlight the team's technical knowledge and willingness to explain recommendations.
Reviews also mention fast service and a lower-pressure approach to repairs and upgrades.
For homeowners who prefer building an ongoing relationship with one HVAC provider rather than hiring separate companies for different system needs, this can be a practical option.
Best for: Commercial facilities and larger duct systems
Air Duct Cleaning & Repairs is based in North Charleston and has operated since 2015.
The company works with both residential and commercial properties, although its commercial capabilities are particularly notable.
It serves properties such as:
Its equipment includes:
The company follows a six-step cleaning process designed for commercial HVAC systems.
Robotic camera inspections are one of the more distinctive parts of the service.
These allow technicians and property managers to inspect ductwork before and after cleaning rather than relying entirely on verbal confirmation.
The company also uses per-square-foot pricing for commercial work, which can make budgeting more predictable for large facilities.
Its A+ BBB rating and consistent five-star Google reviews provide additional credibility.
Customers frequently mention transparent pricing and detailed inspection reports.
Commercial clients in particular appear to value the ability to understand exactly what work was completed and avoid unexpected charges after the service begins.
Best for: Customers who prioritize process consistency and documented results
Ductz of Charleston operates from Ladson as part of the Belfor Franchise Group.
Its services include:
Each job follows a checklist containing more than 100 items.
The company also follows NADCA standards and EPA post-cleaning guidelines.
Documentation is one of Ductz's strongest differentiators.
Customers receive before-and-after photo reports, which provide visual evidence of the condition of the ductwork and the work completed.
The standardized checklist also creates a more structured process than homeowners may encounter with smaller operations that do not clearly document their procedures.
The company offers 24/7 emergency availability as well.
The Charleston location has less review volume than some of the other companies included in this list, so there is less local customer data available for comparison.
However, the franchise-backed systems, documented process, and no-hidden-fee approach provide a clearer baseline for what customers can expect.
Rather than selecting companies based only on ratings, the research process involved several filtering stages.
The first step was identifying air duct cleaning providers serving Charleston and the surrounding metro area.
Sources included:
At this stage, companies were collected broadly rather than ranked immediately.
Basic information such as years in business, service categories, and review volume was also recorded.
The next stage focused on removing companies that could not be verified through multiple sources.
Review histories were examined for recurring concerns such as:
Companies showing repeated problems across platforms were removed from further consideration.
The remaining providers were evaluated by comparing information from their official websites with what customers described in reviews.
For example, if a company promoted specialized equipment, NADCA standards, or detailed inspections, customer feedback was reviewed to determine whether those claims appeared to match actual service experiences.
Companies where customer experiences supported the advertised capabilities were given more weight.
Additional signals were considered, including:
These factors were treated as supporting evidence rather than automatic proof of service quality.
The right provider depends largely on the type of property and the reason you need the service.
Residential and commercial HVAC systems can require very different cleaning methods.
If you manage an office building or retail space, look for a company with specific commercial experience rather than assuming every residential duct cleaner can handle the same work.
Consider whether duct cleaning is your only concern.
If you are also dealing with mold, dryer vents, crawl spaces, water damage, or broader HVAC problems, a company offering several related services may be more convenient.
Ask how the company calculates the cost.
Common models include:
The important part is understanding the pricing structure before work starts and confirming whether additional charges may be added later.
Ask what proof you will receive after the job.
Useful documentation can include:
Companies willing to document their work generally make it easier for customers to evaluate the results.
Credentials such as NADCA and NATE certification can provide an additional indication that technicians have received recognized industry training.
They should not be the only factor considered, but they can be useful when combined with customer reviews, experience, and a transparent cleaning process.
Finding a reliable air duct cleaning company in Charleston requires looking beyond the cheapest quote or highest star rating.
R&E Home Solutions stands out for its combination of local experience, NADCA certification, and broader indoor air quality services. Coastal Carolina Comfort may be a better fit for homeowners who want duct-related work handled as part of an ongoing HVAC relationship. Air Duct Cleaning & Repairs offers stronger commercial capabilities, while Ductz provides a highly structured process with extensive documentation.
Ultimately, the right company will depend on the size of the property, the condition of the HVAC system, and whether you need basic cleaning or additional services such as mold remediation, HVAC repair, or indoor air quality treatment.
