Commercial HVAC Repair, Installation & Maintenance for Large Facilities

When HVAC downtime affects your building, production schedule, tenants, or customers, you need a commercial HVAC company that can diagnose the problem, get the right people on-site, and keep the work moving.

Advanced Comfort Technologies provides commercial HVAC repair, installation, maintenance, controls integration, and Priority Maintenance Program support for large facilities across New York, New Jersey, Connecticut, and Florida.

Our team works on rooftop units, chillers, cooling towers, boilers, hydronic systems, VRF/VRV systems, refrigeration equipment, building automation controls, and high-tonnage commercial HVAC systems.

ACT Is Built to Handle Commercial HVAC Problems

Some HVAC companies are set up for small offices and light commercial service. ACT is built for larger, more complex facilities.

We support commercial and industrial HVAC projects involving high-tonnage rooftop units, large-scale system replacements, complex controls, cooling towers, boilers, warehouse HVAC systems, design-build installations, and mechanical coordination for active facilities.

Need a 500-ton unit set on a large roof system? Need dozens of rooftop units replaced with limited downtime? Need an older building controls system brought up to modern standards? ACT has the field experience and technical depth to help plan the work, solve the problem, and keep your facility operating.

"ACT an amazing partner for our large commercial units and controls systems."
