Built in Houston. By Houstonians. Since 2023.

Houston averages relative humidity levels above 75 percent for much of the year. When warm, moist air enters your duct system through leaks, gaps, or during the cooling process, it creates condensation on duct surfaces. That moisture, combined with dust and organic debris, becomes a breeding ground for mold and mildew. The EPA's indoor air quality guidelines note that mold growth inside HVAC systems can spread spores throughout the entire home every time the system runs, significantly worsening respiratory symptoms and allergic reactions. You can review those guidelines at EPA Indoor Air Quality.

Houston consistently ranks among the worst cities in the nation for allergy sufferers. Cedar, oak, ragweed, and mold are year-round concerns. These allergens collect in your air ducts, are recirculated through your HVAC system, and settle on furniture, bedding, and flooring throughout your home. For households with asthma, COPD, or allergic rhinitis, dirty ducts are not just an inconvenience. They are a health hazard.

Houston summers regularly push temperatures above 95 degrees Fahrenheit, meaning residential and commercial HVAC systems run nearly continuously from May through October. A system working this hard through dirty, clogged ducts expends significantly more energy to move conditioned air. The U.S. Department of Energy estimates that HVAC systems with restricted airflow can use 25 to 40 percent more energy than clean, well-maintained systems. In a city where cooling costs dominate utility bills, this is a number Houston homeowners and facility directors cannot afford to ignore.

Every job begins with a thorough inspection of the entire HVAC system, including the air handler, supply and return ducts, coils, and drain pan. Our ASCS-certified technician documents the condition of the system using inspection cameras and airflow measurement tools. This baseline assessment determines the scope of cleaning required and identifies any areas of concern such as mold growth, pest intrusion, or damaged duct lining.

Before any cleaning begins, we seal off the supply and return registers and connect a high-powered vacuum collection unit to the system. This creates negative air pressure inside the duct system, which is essential to the source removal process. Negative pressure ensures that loosened contaminants are drawn toward the collection unit rather than being pushed into the living space.

This is the step that separates NADCA-certified companies from uncertified operators. Using a combination of contact vacuuming, agitation tools, and compressed air whips, our technicians physically dislodge and extract dust, debris, mold, pet dander, and other contaminants from every section of the duct system. Source removal means the contamination is actually removed from the system, not just redistributed. This is the method NADCA mandates and the only method we use.

Beyond the duct runs themselves, we clean all accessible HVAC components including evaporator coils, blower motors, drain pans, and air handlers. Coil cleaning is particularly important in Houston because dirty coils cannot transfer heat efficiently, which forces the system to work harder and consume more energy.

After cleaning is complete, our technician performs a final inspection using the same camera equipment used at the start of the job. We document the condition of the system post-cleaning so you have visual proof that the work was completed properly. We also test airflow at each register to confirm that the cleaning has improved system performance.
