About Magnum Air, Inc.
Magnum Air, Inc. operates from a Montgomery headquarters at 19513 Keenan Cut Off Road, anchoring the community with two decades of mechanical contracting experience. The company holds a Texas Class B mechanical license and maintains a current rating of 3.4 stars across five published client reviews, a figure tempered by two outlier complaints regarding roadside driver conduct. Serving the greater Houston metropolitan corridor, Magnum Air extends reach into Waller County and surrounding Montgomery County municipalities, where commercial clients include institutional landmarks such as Waller High School and industrial facilities like San Jacinto PetroChemical.
The contractor distinguishes itself through commercial Building Automation System integration, managing complex rooftop unit deployments alongside fan-powered boxes, ductwork, and advanced BAS controls. Portfolio highlights demonstrate competency in summer-turnaround timelines requiring ceiling removals and equipment upgrades under compressed schedules. The company maintains secondary phone lines for responsive scheduling and projects a commitment to exceeding customer expectations, though specific manufacturer partnerships or warranty terms remain undefined on their digital platforms.
Client testimonials acknowledge specific team members including Terry Running, credited for team-oriented project execution and professional client relationships. One homeowner account describes a recent collaboration expressing satisfaction with topline professionalism, while another reviewer emphasizes staff courtesy and polite interactions. The referenced testimonials align with Magnum Air's stated dedication to service excellence, though documented emergency-response anecdotes or same-day availability specifics do not surface in current review archives.
What Customers Say
Two of five reviews explicitly criticize reckless roadside behavior by vehicle operators, while the remaining three reviews award five-star ratings citing professional project execution and courteous staff interactions. Positive feedback references a Terry Running as team-oriented, contrasting with unresolved driver-conduct concerns raised in anonymous complaints.
