What We Do

Our HVAC VFD Retrofit Services in Manhattan

Retrofit, integration, and ongoing support for variable frequency drives — cutting energy costs across Manhattan's commercial buildings.

⚡

VFD Retrofit for Fans & Pumps

We install variable frequency drives on existing supply fans, exhaust fans, and pumps so motors modulate speed to actual demand instead of running at full speed continuously.

🔌

Existing MCC & Panel Integration

Most Manhattan buildings can retrofit VFDs into existing motor control centers without a full electrical overhaul — we assess your panels and integrate drives with minimal disruption.

📊

Building Automation Integration

VFDs deliver the biggest savings when tied to real demand signals — we integrate drives with your BAS or 75F platform so speed responds to occupancy, temperature, and static pressure.

🌿

LL97 Energy Savings Documentation

Motor energy is a significant, quantifiable share of a building's electricity use. We document the measured kWh reduction from your VFD retrofit for Local Law 97 reporting.

🔧

VFD Programming & Commissioning

Drives are only as good as their programming — we set acceleration curves, minimum speeds, and fault protections specific to your equipment, not factory defaults.

🛠️

Ongoing VFD Maintenance & Support

We service and troubleshoot installed drives, replacing cooling fans, capacitors, and firmware as needed to keep your Manhattan building's energy savings intact for the long term.

LL97 Note: Manhattan buildings over 25,000 sq ft face escalating carbon penalties starting 2024. VFD retrofits on fan and pump motors routinely cut motor energy use by 30–50%, making them one of the fastest-payback upgrades available against your building's emissions exposure.

From assessment to energy savings

One partner handles every step. Here's how we do it.

Motor & load assessment

A Denair engineer surveys your Manhattan building's fan and pump motors, existing electrical panels, and actual operating loads to identify the highest-value VFD retrofit candidates.

Drive spec & integration plan

We spec drives sized to each motor, confirm MCC and panel compatibility, and design the BAS integration so speed control ties to real demand signals.

Fixed-price proposal

You receive a clear, itemized quote covering drives, electrical integration, and programming before installation begins. What we quote is what you pay.

Install, program & commission

Certified electricians install and wire the drives, then program acceleration curves and fault protections, and commission against your BAS before handoff — with measured energy data documented.

Questions we hear every day

Straight answers about hvac vfd retrofit in Manhattan — no marketing fluff.

How disruptive is a VFD retrofit for a Manhattan building?

VFD retrofits are typically scheduled system by system so the building's HVAC never fully loses fan or pump capacity during the project. Most installations into existing motor control centers take a day or two per drive, and Denair schedules electrical work during low-demand periods to minimize any impact on building comfort.

Is Denair certified to install VFDs on commercial HVAC systems?

Yes. Denair's technicians hold factory training on major VFD manufacturers alongside broader certifications across Trane, Carrier, AAON, and Daikin equipment — meaning drives are sized, wired, and programmed correctly for your specific motors, protecting both the drive and motor warranty.

How do VFD retrofits help with Local Law 97 compliance?

LL97 caps carbon emissions for Manhattan buildings over 25,000 sq ft, and motor energy from fans and pumps is a large, quantifiable share of most commercial buildings' electricity use. VFDs routinely cut that motor energy by 30–50% by matching speed to actual demand instead of running constant-speed. Denair documents the measured kWh savings for your LL97 filing.

What does a VFD retrofit cost for a Manhattan building?

Cost depends on the number of motors, horsepower, and whether existing electrical panels can accommodate the drives without upgrades — a single fan retrofit costs considerably less than a building-wide multi-drive project. Denair provides a fixed, itemized quote after the motor assessment, and most projects show a clear energy-savings payback timeline as part of the proposal.

Will VFDs work with our building's existing automation system?

In most cases, yes — VFDs communicate via standard protocols that integrate with 75F, Honeywell, Johnson Controls, and most legacy BAS platforms, allowing drive speed to respond automatically to occupancy and demand signals rather than running on a fixed schedule. Denair confirms compatibility with your specific system during the assessment.
