UV GERMICIDAL LIGHT
$490
A UV Germicidal Light is a device installed in an air conditioning system to help improve indoor air quality by killing bacteria, viruses, and mold that can grow in the system’s coils and ducts. UV Germicidal Light can disrupt the DNA of microorganisms, rendering them unable to reproduce or cause harm.
DUCT REPAIR AND REPLACEMENT
Fixing or replacing the ducts that carry cooled or heating air from the air conditioner throughout a building. Repairing ducts can address issues like leaks, disconnections, or blockages that reduce airflow and efficiency, leading to higher energy costs and uneven cooling. When ducts are severely damaged or old, replacement is often the best option to improve airflow, energy efficiency, and indoor air quality. This process typically involves removing the old ducts, installing new ductwork, sealing connections and insulating to prevent future leaks.
CHIMENY CLEANING
$120
Chimney cleaning removes soot, creosote, and debris from the flue to prevent fire hazards and improve airflow. Fireplace inspection checks for structural issues, blockages and signs of damage or wear, ensuring safe and efficient operation. Both steps help maintain safety, efficiency and longevity of the fireplace and chimney.

Clear answers
BEFORE YOU SCHEDULE
Yes. Your HVAC system moves the air you breathe throughout your home every day. If dust buildup or microbial growth is present inside the ductwork, those particles can continuously circulate through your living space.
Over time, this may contribute to:
* Chronic allergies
* Sinus congestion
* Respiratory irritation
* Asthma flare-ups
* Headaches and persistent fatigue
* Musty odors linked to microbial growth
Because contamination inside ducts is not visible from the outside, many homeowners are unaware of the condition of their system until symptoms persist.
If you notice visible dust buildup, musty odors, recent remodeling, rodent activity, or inconsistent airflow, your system may require professional cleaning. Commercial properties and high-traffic buildings often require more frequent inspection due to higher contamination levels. A proper HVAC inspection determines the true condition of the system.
Microbial growth inside an HVAC system can impact indoor air quality and trigger allergies or respiratory irritation. If confirmed, affected components must be properly cleaned, and in some cases replaced, according to industry standards. A professional inspection determines the appropriate corrective action.
A mildew smell usually indicates microbial growth inside the HVAC system.
Moisture from condensation can accumulate on the evaporator coil, inside plenum boxes, or within ductwork—especially in humid climates like Texas.
If not professionally cleaned, these areas can develop mold, bacteria, or organic buildup that circulates odors throughout the home or building.
A complete HVAC inspection determines the source and whether cleaning, restoration, or coil treatment is required.

Why Homeowners Trust Southern Air Duct Cleaning?
Do not just take our word for it, read what our customers say.
For years, my family had been struggling with unexplained health issues, and it wasn't until Mario and his team got to work that we finally discovered the root of the problem—black and green mold hidden deep within our air ducts. This issue had been festering for years, slowly impacting our health, but Southern Air Duct Cleaning tackled it with remarkable efficiency and expertise. They were vigilant in addressing every nook and cranny, ensuring that no trace of mold was left behind.
When I returned home after the cleaning, I was amazed at the difference. The air was crisp and fresh, and for the first time in years, I could breathe easily. The change in my body was immediate—I felt relaxed and at peace, no longer in a constant state of survival mode. It was as if a heavy weight had been lifted off my shoulders.
I cannot thank Mario and his team enough for their dedication and professionalism. They truly went above and beyond, solving a problem that had plagued us for far too long. Southern Air Duct Cleaning of Texas has my highest recommendation, and I am deeply grateful for the outstanding service they provided. If you're looking for a company that will treat your home with the utmost care and deliver exceptional results, look no further. Mario and his team are simply amazing!


One thing that impressed me about this company was that they provided me with a clear and detailed quote before starting the job. There were no surprises or hidden charges at the end of the service. Considering the quality of the work done and the time they spent.
I am extremely pleased with the result and will certainly consider them for future cleaning needs.
I highly recommend southern air duct cleaning for dryer vent cleaning services.
