Commercial HVAC Services Built for Large Facilities
When downtime costs real money, you need a partner who shows up ready to fix the problem—not sell you something you don’t need. ACT provides commercial HVAC installation, repairs, maintenance, and controls integration for large facilities across New York, New Jersey, Connecticut, and Florida. We specialize in keeping complex, high-tonnage systems up and running with minimum disruption.
Solving Tough HVAC Problems
Whatever your commercial HVAC problem is, chances are we’ve solved it before or can help you solve it now. Need a 500 ton unit set in the middle of a 2 Million sq/ft roof system? We’ve done that. Need 30 60 ton units replaced? We’ve done that. Need old building control systems replaced? We’ve done it. We’ve done ducting for massive new warehouses, and for multi-million dollar car museum collections.
Most importantly, our crew gets equipment hooked-up and running in days, not weeks. Plus, clients who sign up for our PMP (Priority Maintenance Program) enjoy constant uptime thanks to regular checks and remote monitoring that spots minor problems before they become expensive emergency repairs.
