What We Do

Commercial HVAC and Retrofits

From office buildings to retail environments and multi-unit properties, we design and install HVAC systems built to handle real-world loads and NYC constraints.

Services include:

  • Rooftop Units (RTUs)

  • Split systems

  • Packaged systems

  • Ductwork modifications

  • System upgrades and replacements

If your system is outdated, undersized, or consistently underperforming, we can correct it.

Preventative Maintenance

Breakdowns are expensive. Preventative maintenance is not.

Our maintenance programs are designed to reduce downtime, extend equipment life, and stabilize operating costs. Programs include:

  • Seasonal inspections

  • Coil cleaning

  • Filter replacement

  • Performance testing

  • Refrigerant checks

  • Electrical diagnostics

The result: fewer surprises, longer equipment life, and more predictable operation.

VRF/VRV Systems

Modern buildings demand flexible, efficient climate control. Variable Refrigerant Flow (VRF) systems provide independent zone control, improved efficiency, and lower operating costs.

We design, install, and service VRF systems for:

  • Mixed-use buildings

  • Commercial office and retail spaces

  • Multi-family properties

Targeted comfort. Measurable efficiency. Long-term value.

Energy Efficiency and System Optimization

If energy costs are rising but comfort and performance are not improving, something is misaligned.

We evaluate:

  • System sizing

  • Airflow balance

  • Controls calibration

  • Equipment efficiency

  • Duct integrity

Then we optimize performance—often without unnecessary equipment replacement.

HVAC Repair and System Troubleshooting

When systems fail—or fail repeatedly—we respond quickly and address the actual cause, not just the symptom.

We service and troubleshoot:

  • Heating and cooling systems

  • Air handlers

  • Condensers

  • RTUs

  • Control systems

Our diagnostics are thorough, and our repairs are designed to hold.

Forensic HVAC Assessments

Some problems are persistent for a reason.

Our Forensic HVAC Assessment is designed for buildings with recurring failures, unresolved comfort issues, or questionable past installations. We analyze:

  • Load calculations vs. actual demand

  • Improper equipment sizing

  • Duct design deficiencies

  • Control system misconfigurations

  • Installation errors

  • Manufacturer defects

You receive a clear diagnostic report with actionable recommendations—whether for repair, redesign, documentation, or third-party review.

Evidence-based HVAC problem solving.
