From preventive maintenance and emergency repairs to mechanical retrofits and new construction. ACIS fixes what’s actually wrong and stands behind the result.
Commercial HVAC Services
ACIS provides commercial HVAC services to facilities across Dallas, Fort Worth, and Houston — from preventive maintenance and emergency repairs to mechanical retrofits, new construction, and full project delivery. Whatever the scope, our approach is the same: find out what’s actually going on, fix it right, and stand behind the result.
Many of the buildings we work in have been through other contractors first, systems that were patched instead of fixed, or installations where the original contractor is long gone once the warranty period ends. ACIS is often the team called in to figure out what’s actually wrong and get it right.
HVAC Services
Preventive Maintenance
Scheduled maintenance programs that catch problems before they become failures, reducing downtime, extending equipment life, and keeping your systems running efficiently year-round.
Emergency Service
24/7 emergency response across Dallas, Fort Worth, and Houston. When a system goes down, our technicians are dispatched to diagnose the problem and get your facility back online, fast.
Mechanical Retrofits
Equipment upgrades, VRF system installation, retro commissioning, and modernization projects that improve performance, reduce energy costs, and extend the life of your mechanical systems.
New Construction
Blueprint consultation through installation and commissioning, ACIS works with general contractors and developers from the design phase forward, including specialized experience with medical and government facilities.
HVAC Projects
Chiller changeouts, RTU replacements, boiler replacements, and full mechanical retrofits, managed by an experienced project team with the multi-trade capabilities to keep complex projects on schedule.
