Duct cleaning contractors — San Antonio, TX

Last updated: September 24, 2026

When the South Texas sun beats down on San Antonio, you're likely running your air conditioning system hard, pushing air through ductwork that can accumulate a significant amount of particulate matter over time. Given San Antonio's density of nearly 3,000 people per square mile, the internal environment of your home or business can become a repository for dust, pet dander, mold spores, and other allergens circulating through your HVAC system. This build-up not only compromises the air you breathe but also impacts the operational efficiency of your cooling and heating equipment. Our licensed and insured pros serve every neighborhood in San Antonio, from the historic King William District to the sprawling suburbs near New Braunfels and Austin. They employ advanced methods, including negative air pressure techniques with robust containment protocols, ensuring that removed contaminants are properly captured and disposed of. This meticulous process addresses the root cause of poor indoor air quality, creating a healthier living and working environment. The specialists we dispatch are adept at assessing varying ductwork configurations, common in older homes throughout the city and newer constructions alike. They utilize industrial-grade vacuums and fogging agents, where appropriate, to sanitize and clear even deeply embedded particulates. Your comfort and health are paramount, especially during those long, hot San Antonio summers. Understanding the specific needs of local residences and commercial spaces, our service providers are equipped to handle diverse HVAC systems. This thorough approach can contribute to reduced energy consumption by allowing your system to operate with less strain. The pros we work with are committed to delivering a comprehensive cleaning that addresses the entire ductwork network. Call now for a free estimate.

What affects the price

The final bill for your air duct service depends on a few straightforward factors. We look at the total square footage of your home, the number of vents and return registers you have, and the specific layout of your HVAC system. If you have multiple furnace units or an especially complex ductwork configuration, that adds to the labor time. We also consider the level of buildup inside the system, as systems that haven't been cleaned in many years often require extra attention to get debris-free. We keep things simple and honest. Exact pricing confirmed free on the call.
