Air Duct Cleaning San Antonio

Your heating, ventilation, and air conditioning system (HVAC) act as a collection source for a variety of contaminants that have the potential to adversely affect your health. As the system draws in and redistributes the air in a building, the airborne dirt and dust gather within the duct system and components which can decrease its efficiency and contribute to poor indoor air quality. Contaminants such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home is an important step to improve your indoor air quality. 

​As more and more debris accumulates within the air ducts, the system is forced to work harder which leads to higher energy bills as well as indoor air pollution. The technicians of Stay Fresh Steam Cleaning can completely remove contaminants from the entire air duct system using the most advanced equipment available in the industry. If the air duct system in your home in San Antonio, TX could benefit from professional cleaning, contact Stay Fresh Steam Cleaning for our air duct cleaning San Antonio services.

What to do About Air Duct Contaminants


To clean your air ducts and ventilation systems, Stay Fresh Steam Cleaning employs the Source Removal method of cleaning. Our qualified technicians place your system under negative pressure, through the use of a specialized, powerful vacuum. While the vacuum draws air through the system, devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home. Some lower cost methods merely vacuum the duct. Our system actually scrubs each duct to get the dirt free using a vacuum and high-pressure air from brushes.

Ways Dirty Air Ducts are Affecting Your Health

Air Duct Cleaning Benefits

There are many benefits to having your air ducts professionally cleaned, the top five of which are listed below:

  1. Creates a Cleaner Living Environment

    • Having your air ducts professionally cleaned reduces the dust that would otherwise circulate throughout your living space, landing on your furniture, your bedding, your flooring…just about everywhere. Fortunately, a thorough air duct cleaning reduces the amount of interior cleaning and dusting necessary to maintain a hygienic home.

  2. Reduces Allergens and Irritants

    • In addition to dust, air ducts frequently contain harmful contaminants and micro-organisms. These include pet dander, bacteria, pollen, mildew, mold spores, and similar toxins. People who suffer from allergies, asthma, and other respiratory problems are particularly sensitive to these airborne particles. A periodic air duct cleaning promotes healthier living…otherwise the dirty air in your home just keeps re-circulating over and over.

  3. Helps Everyone Breathe Easier

    • Even if no one in your household suffers from chronic allergies or respiratory problems, cleaner air makes it easier for everyone to breathe. Even among the most healthy, dust and pollutants entering the nose and lungs can trigger sneezing and coughing, as well as sinus and bronchial congestion. Air duct cleaning creates a more comfortable environment and promotes well-being. Given the choice between clean air and dirty air, which would you rather breathe?

  4. Removes Unpleasant Smells and Odors

    • Pets, household cleaning agents, paint fumes, mold, tobacco use and even food preparation all contribute to stale smells in the air ducts. Every time the furnace or air conditioner is running, these odors will repeatedly flow through the house. Even an accumulation of dust and dirt over the years can lead to a musty scent coming from the ductwork. A detailed cleaning of the air ducts removes all odor trapping particles, resulting in a fresher smelling home.

  5. Improves Air Flow Efficiency

    • Ductwork and registers that have a heavy build-up of dust and grime can restrict the flow of air from the furnace and air conditioner. This means your system will have to work harder to heat or cool your home, resulting in a decreased level of efficiency. Conversely, a clean system will operate at peak efficiency and provide the most cost-effective performance for your energy dollar.

Proper Air Duct Cleaning Methods:

Regardless of what equipment is used, it is essential that certain methods are used during an duct cleaning process. These safe methods ensure that your air ducts are left completely clean, with no contaminants released into your home in the process.

Breaking Contaminants Loose: Properly cleaning air ducts requires removing the sources of contamination. This begins with the use of one or more agitating devices designed to loosen contaminants from the surfaces of the duct work.

We use Rotary Brush method which is the use of a spinning brush that scrubs the ductwork to loosen contaminants and a vacuum system to suck away the debris. The rotary brush method is the preferred choice for residential & light commercial duct cleaning work, because a brush will provide better scrubbing power and a better cleaning.

Collection of Contaminants: During your duct cleaning we put your duct work under negative pressure (vacuum) to prevent the spread of contaminants (dust, hair, etc.). Continuous negative pressure allows very fine particles to be removed from the system as they become air borne, ensuring that these particles are not released in to the living space when the system is turned back on after the cleaning.

System Access: Since each house or building is unique in its own way, each HVAC system is set up differently. Where possible, our technician will access your air ducts through all of your registers, cold air returns, and will also cut access holes in the duct work in order to reach inside with various cleaning tools.
