HVAC Mold Inspection & Cleanup in Harris County
Your HVAC system is designed to keep you comfortable—but when mold takes over, it can become a serious health hazard. In Houston’s humid climate, air ducts and HVAC units provide the perfect breeding ground for mold, spreading spores and bacteria throughout your home or business. This isn’t just an inconvenience; it can trigger allergies, asthma, and other respiratory issues.
At Lone Star Pro Services, we believe in real solutions—not temporary fixes. That’s why we specialize in complete mold removal for HVAC systems and ductwork.

If you notice any of the following, it’s time to call us:
Think you can solve the problem with a simple cleaning? Think again. Mold doesn’t just sit on the surface—it burrows into insulation, hides in hard-to-reach spaces, and resists conventional cleaning methods.
Even the best cleaning techniques leave spores behind, allowing mold to regrow. If mold is in your HVAC system, the only real solution is complete removal.
When mold infiltrates your HVAC system, complete removal is the only way to ensure long-term protection. Our specialized mold remediation process is tailored to your system, prioritizing health, safety, and long-lasting results.
Sanitization, fogging, and chemical treatments may seem like quick solutions, but they only provide temporary relief. As the experts, we’ve seen these methods fail time and time again.
While we offer temporary sanitization for short-term relief, we’re always upfront—true mold remediation requires complete removal.




We inspect the HVAC system, ductwork, and surrounding areas to find where mold is present and what caused it. This includes visual checks, moisture readings, and airflow evaluation to understand how mold is spreading through the system.
We isolate the affected HVAC areas to prevent mold spores from spreading through the home. Barriers and controlled airflow are used so the rest of the property remains protected during the process.
Mold is carefully removed from HVAC components, ducts, and nearby surfaces using professional equipment and approved cleaning methods. All contaminated debris is safely handled and disposed of to restore clean air circulation.
We address moisture and airflow issues that allow mold to return. This may include recommendations for ventilation improvements, humidity control, and system adjustments to help keep your HVAC system clean long term.

We are proud to have earned the trust and confidence of our customers through our commitment to excellence and exceptional service.

George and his team were incredibly caring and professional. Our home has never smelled or looked so clean. Moving back into the place that gave our family mold illness was scary and emotional. I am extremely grateful to Lone Star Pro for making that transition easier on our hearts and minds. We would absolutely recommend them and their services. Thanks again, GeorgePosted on Google![]()

I didn’t use their services, but I did reach out to inquire information on air duct cleaning a couple of weeks ago. George pointed me in the right direction and I am so thankful. He saved us a lot of money. Also thankful that he understands those of us with CIRS. I then recommended him to a friend of mine whose son is extremely sensitive for a new build they were having issues with, because of everything I’d heard of about Lone Star and how I know they take care of sensitive groups over a typical remediation company. She spoke so highly of him as well. Their house passed their post remediation test through the best mold inspection company I’ve known since they started. Now I also know who to use should, God forbid, I personally need their services. I will continue to recommend Lone Star to those having issues with mold, because I know they’ll do it right. George is a wonderful man. Thank you from both me and my friend, George!
Mold gets into HVAC systems when moisture builds up inside the unit or ductwork. This usually happens from high humidity, condensation on coils, clogged drain lines, or past water damage. Once moisture is present, mold can grow and spread through the system as air moves.
Yes. When mold is inside the HVAC system, it can circulate spores through the air every time the system runs. This can affect indoor air quality and may cause odors, irritation, or respiratory discomfort, especially for children, elderly occupants, or anyone with allergies or asthma.
In many cases, continued use can spread mold spores throughout the property. It is best to limit use until the issue is properly evaluated. Our HVAC mold experts can determine whether the system should be shut down or operated in a controlled way during cleanup.
