EXCELLENT Based on 45 reviews Posted on Jim EstesSeptember 4, 2025Trustindex verifies that the original source of the review is Google. We own our own HVAC company and I observed as they were completing a duct renovation at our lake neighbor’s house. The crew was very organized and professional and made it a point to come over and speak to us. Later in the day, I inquired how the job went and one of the crew took pride in showing me how it looked. I’ve been in HVAC for over 30 years and their duct work looked exceptional. Keep up the great work!Posted on Jan HuffmanAugust 29, 2025Trustindex verifies that the original source of the review is Google. This company did a wonderful job… they were in touch with me enroute. Once at the hiouse they explained everything, educated me on reasons I was having mold issue, discovered a duct that should not have been present, cleaned everything up and were courteous the entire time.Posted on James VanwinkleAugust 27, 2025Trustindex verifies that the original source of the review is Google.

We had our ducts cleaned today. Chris and Steve did an excellent job. They were very thorough. They also went above and beyond. For example… not only did they clean all the hvac ducts, they sealed the boots of the ducts, cleaned my dryer vent and the coils on my hvac unit. It’s nice to have people that take a lot of pride in their work and these guys did!Posted on Paul ParkersonMay 12, 2025Trustindex verifies that the original source of the review is Google. I had Mr. Dirty Ducts out to the house after a sand and finish of my hardwood floors to clean the HVAC system. Greg, Chris and the crew were awesome efficient and did a wonderful job. I would highly recommend.
Why Your Crawl Space Needs Waterproofing—Even If You Never Go Down There?
You probably don’t think about your crawl space but if it’s damp, musty, or unsealed, it could be quietly causing real problems. That hidden moisture doesn’t stay underground, it rises into your home, carrying mold, pests, bad smells, and high humidity with it. Over time, it can warp your floors, damage insulation, and make your indoor air feel thick or unhealthy.
That’s why installing a vapor barrier is one of the simplest, most effective ways to protect your home from these issues before they get worse.
At Mr. Dirty Ducts, we install heavy-duty, professional-grade vapor barriers that seal off the ground and stop moisture at the source. Whether you’re noticing signs of crawl space problems or just want to prevent them we’re here with NADCA- and IICRC-certified expertise trusted across Middle Tennessee.

Why Professional Installation Matters?
Installing a vapor barrier isn’t just laying down plastic, it takes planning, product knowledge, and precision. The type of barrier and its placement depend on your home’s structure and climate zone.
- In humid southern climates like Middle Tennessee, vapor barriers are usually placed toward the exterior to block ground moisture.
- In colder climates, placement is reversed to keep indoor moisture from reaching cool surfaces.
- Even the permeability rating (how much vapor it allows through) must be chosen carefully based on your conditions.
That’s why professional installation done by NADCA- and IICRC-certified specialists matters. We make sure your barrier is sealed, secured, and built to perform long-term.
