Assured Comfort Services (operating also as Innovation HVAC) is a licensed commercial HVAC and plumbing contractor based in Dallas, holding Texas HVAC License #TACLA21446E, Plumbing License #M-13915, and State of Texas HUB certification — the Historically Underutilized Business designation that qualifies them for public sector and government contracts. Their NCTRCA certification further validates their standing for North Central Texas Regional Certification Agency requirements.

The scope of equipment they service is extensive: centrifugal chillers, air-cooled chillers, cooling towers, air compressors, air handlers, boilers, rooftop packaged units, split systems, mini splits, variable frequency drives, VAV and fan-powered boxes, computer room equipment, and controls. On the plumbing side: water heaters, small boilers, pumps and valves, drain cleaning, water lines, and sanitary systems. This is a commercial/industrial capability set, not a standard residential contractor.

The company offers 24/7 on-call service for both HVAC and plumbing, and reviews from commercial clients describe on-time, within-budget project completion and individual technicians — Robert Stumbo and Billie are specifically named — who demonstrate attention to detail and follow-through. A construction business owner describes working with Assured Comfort for full inside unit replacement and returning for repeat work based on the quality of the first project.

For commercial property managers, building engineers, and general contractors in Dallas who need a fully credentialed, HUB-certified mechanical contractor, Assured Comfort Services is worth evaluating. Their multi-system capability and public-sector qualifications distinguish them from standard residential HVAC companies.
