VFD retrofits
that cut energy
costs in Brooklyn
buildings, fast
Denair retrofits variable frequency drives onto Brooklyn's existing fans, pumps, and compressors — reducing energy draw and easing LL97 exposure without replacing working equipment.
Our HVAC VFD Retrofit Services in Brooklyn
Retrofit variable frequency drives onto your existing HVAC equipment — cutting energy costs across Brooklyn's commercial buildings without a capital equipment overhaul.
Fan & Pump VFD Retrofits
We install variable frequency drives on existing supply, exhaust, and condenser fans as well as chilled and hot water pumps, letting motors run at the speed your building actually needs instead of full speed constantly.
RTU & AHU Compressor VFD Integration
Retrofitting VFDs onto rooftop unit and air handler compressors allows capacity to match real-time load, extending equipment life while cutting energy consumption.
Energy Savings Analysis
Before any retrofit, we model expected energy savings for your specific Brooklyn building and equipment mix, so you know the payback timeline before committing.
LL97 Emissions Reduction
VFD retrofits are one of the fastest, lowest-disruption ways to cut a Brooklyn building's HVAC-driven emissions — directly addressing Local Law 97 exposure without a full system replacement.
BAS Integration & Sequencing
We integrate new VFDs with your existing building automation system, so speed control responds automatically to occupancy, temperature, and demand rather than running on a fixed setting.
Ongoing VFD Maintenance & Support
Post-installation service keeps drives calibrated and firmware current — a poorly maintained VFD can quietly lose the efficiency gains it was installed to deliver.
From energy audit to measurable savings
One partner handles every step. Here's how we retrofit your building.
Equipment & load assessment
A certified engineer surveys your Brooklyn building's fans, pumps, and compressors to identify the best VFD retrofit candidates for savings and payback.
Savings modeling & design
We model expected energy reduction for each proposed retrofit and design the electrical and controls integration around your building's existing systems.
Fixed-price retrofit proposal
You receive a clear, itemized quote with projected payback timeline before any work begins — no hourly surprises or scope creep mid-project.
Installation & commissioning
Technicians install and commission each VFD, integrating with your BAS where applicable and verifying performance against the modeled savings target.
