Beau and his team were incredible. They showed us before and after photos of every single vent — you could actually see the difference. Our house feels fresher and my daughter's allergies are so much better.

Best money I've ever spent on the house. No high-pressure upsells, just honest work. They cleaned the dryer vent from the outside and my drying time is literally cut in half.

Family owned and it shows. On time, respectful of our home, and they walked me through everything they were doing. The video from inside the trunk line was eye-opening. Highly recommend.

What We Do

Our Services

Professional Air Duct Cleaning

We use a powerful HEPA-filtered negative air vacuum system paired with positive compressed air to provide a thorough, professional air duct cleaning. This industry-standard method delivers the same cleaning performance as many truck-mounted systems while allowing us to safely and effectively remove contaminants from your HVAC system. We also have the truck-mounted system to be used when appropriate.

Our process creates continuous negative pressure throughout your ductwork, preventing dust and debris from escaping into your home during the cleaning. Specialized compressed air tools then loosen dirt, dust, pet dander, pollen, construction debris, and other contaminants from deep within the ducts, where they are immediately captured by our high-powered HEPA-filtered vacuum system.

Dryer Vent Cleaning

Our dryer vent cleanings are performed from the outside of your home using specialized compressed air equipment. This process safely removes lint, dust, and debris while keeping the mess outside — where it belongs. There's no need to worry about lint or dust being blown into your home.

A professionally cleaned dryer vent can help:

  • Improve dryer efficiency
  • Reduce drying times
  • Reduce the risk of dryer fires caused by lint buildup

Air Quality Improvement

Breathe cleaner, healthier air with our indoor air quality solutions. Mighty Dux LLC offers professional installation of the Air Scrubber by Aerus and whole-home humidifiers to help create a more comfortable living environment.

Air Scrubber by Aerus

Installed directly into your HVAC system, the Air Scrubber by Aerus uses ActivePure® Technology to help reduce airborne and surface contaminants throughout your home. It works to reduce dust, odors, allergens, mold spores, bacteria, and viruses while continuously improving your indoor air quality.

Whole-Home Humidifiers

A whole-home humidifier adds the right amount of moisture to the air throughout your entire home. Maintaining proper humidity levels can help reduce dry skin, irritated sinuses, static electricity, and damage to wood floors and furniture, while making your home feel more comfortable during the dry winter months.

Whole-Home Sanitization

Our whole-home sanitization process is designed to provide more complete coverage throughout your HVAC system. Unlike many companies that use a heavier mist, we use a specialized sanitizing fog that is lightweight enough to travel through your ductwork more effectively. This allows the treatment to reach more areas of your HVAC system and your home's air distribution network.

Our sanitization service helps reduce odors and treats your HVAC system using an EPA-registered sanitizing product applied according to the manufacturer's directions, leaving your home feeling cleaner and fresher.
