M & M Controls

M & M Controls has operated from Alexandria since 1987 as a specialized supplier of environmental control systems to the commercial and industrial HVAC marketplace, serving property managers, building engineers, and HVAC contractors across Maryland, Virginia, D.C., and Central Pennsylvania. With a 4.9 rating drawn from 33 verified reviews, the company maintains a focused inventory of electronic controls and components backed by a team of knowledgeable staff who understand technical specifications and system compatibility. The business operates weekdays from 6:30 AM to 4 PM, closed on weekends, which serves the scheduling needs of commercial clients who place orders during standard business hours.

What distinguishes M & M Controls is their dedication to sourcing hard-to-find control components and their long-standing focus on this narrow product category rather than attempting to be a full-service HVAC company. The business emphasizes continuous training for their team and partnerships with major control manufacturers, allowing them to provide innovative solutions for building automation and environmental management systems. Multiple reviewers specifically mention the willingness of staff to locate obscure parts and find workarounds when standard inventory does not include a needed component, a service level that commercial clients with specialized equipment depend upon.

Customer reviews consistently highlight individual team members who deliver exceptional service. Arsenio receives repeated mention across multiple reviews, with one Chief Engineer praising his commitment to locating required parts even during extended work hours. Reviewers describe staff as knowledgeable, patient, and willing to educate customers on products and system requirements. Multiple clients emphasize that the team goes above beyond standard supplier service, acting as a technical resource rather than simply filling orders.
