Our unique advantage is our leadership: registered Professional Engineers (PE) with decades of experience managing projects up to $95 million.

We serve a wide range of sectors, including hospitality, retail, high-rises, data centers, and industrial manufacturing.

The air inside your home or business can be more polluted than the air outside, especially in Los Angeles. Poor indoor air quality can trigger allergies, asthma, and reduce overall well-being. A/C Control Inc. offers science-backed indoor air quality solutions to create a healthier, cleaner living and working environment.

Led by a certified chemical engineer, we take a precise approach to IAQ. We first help identify the pollutants affecting your space—whether it's pollen, dust, mold, volatile organic compounds (VOCs), or wildfire smoke particulate. Then, we recommend and install the right combination of technologies to address the root cause.

Our solutions include high-efficiency particulate air (HEPA) filtration, UV-C light systems that safely kill mold, bacteria, and viruses at the coil, air scrubbers that neutralize odors and chemical vapors, and whole-home humidifiers/dehumidifiers to maintain perfect moisture levels. We also integrate IAQ solutions with your existing HVAC system through proper ventilation strategies and duct sealing. Breathe easier knowing your air is being purified by experts who combine cutting-edge technology with a deep understanding of environmental chemistry.
