Automated Ceiling Registers, LLC (ACR) was founded in June of 2000 by Dale Ezell and Lynn Heitman, who are both electrical engineers, and Bob Ezell, a home and apartment builder.  Dale and Lynn worked together at Texas Instruments on a variety of electrical and mechanical control systems and have extensive experience and expertise in a wide range of engineering disciplines.  Both are inventors that hold key patents in the HVAC field and other disciplines.  Bob Ezell, who passed away suddenly in July, 2001, had over thirty-five years experience in developing residential subdivisions and building individual homes and large apartment complexes in several states.  His wife, Janis, continues as a partner and advisor to the company.  A fourth partner, John Smith, with an extensive background in computer-aided design and manufacturing, joined the company in April of 2002.  

From the beginning, ACR's goals have included developing simple airflow control devices that were easy to install and easy to operate.  The primary emphasis of all products has been to improve comfort and save energy.  The concept of complimentary airflow control was developed and patented by the company as a simple method of providing zoning without complication.  Modular phone jacks and cables are used on most of the products to improve installation time and enhance reliability.   A proprietary patented airflow control valve was developed to replace conventional metal blade registers and dampers.  This device provides quiet and efficient linear airflow control over a wide range of flow rates.  In 2003, ACR introduced a line of Air Quality Systems (AQS) to provide fresh air ventilation in residential and light commercial applications. These devices share the proprietary airflow control valve and include airway sensors that monitor and control the temperature and humidity of ventilation air.  In 2006, ACR introduced the Quick and Easy™ Register System, which eliminates the need for ceiling register boxes and provides further reductions in installation time and labor in new home construction.  When used collectively in home or light commercial applications, ACR products provide significant energy savings, improve indoor air quality and enhance temperature balance.  

The MicroFlow2000™ and the Quick & Easy™ register products are offered with manual or automated (motorized) control.  The AQS products are fully automated and provide the proper amount of outside ventilation air in a controlled and energy efficient manner. All ACR airflow control products are made of high quality ABS plastic, molded into aerodynamic shapes, which provide superior airflow performance and unsurpassed control. Unlike conventional metal airflow control devices, they do not rust, rattle or collect dust.  ACR registers provide quiet, continuously variable airflow and are totally sealed when closed.  ACR products allow occupants to continuously control the amount of airflow on a room-by-room basis while maintaining proper indoor air quality throughout the structure.
