Our Energy Recovery Ventilator Installation Services in Brooklyn
Design, installation, and controls integration — keeping Brooklyn buildings code-compliant and energy-efficient.
ERV System Design & Sizing
We calculate your Brooklyn building's actual fresh-air requirement under ASHRAE 62.1 and size the ERV core and ductwork to match — not an oversized unit that wastes fan energy.
New Construction & Retrofit Installation
Whether you're building out new space or retrofitting fresh-air requirements into an existing Brooklyn building, we handle ductwork routing, core installation, and controls integration.
Heat & Energy Recovery Core Service
The recovery core is the heart of the system — we service, clean, and replace cores to keep recovery efficiency near its rated performance instead of degrading silently over years.
LL97 Energy Savings Documentation
ERVs can recover up to 80% of the energy otherwise lost conditioning outside air. We document the measured energy savings your Brooklyn building can use in Local Law 97 reporting.
Controls & BAS Integration
We tie your ERV into existing building controls or 75F/Honeywell platforms so ventilation scales automatically with occupancy rather than running at a fixed rate around the clock.
Preventative Maintenance Contracts
Custom maintenance plans keep filters, cores, and fans performing at rated efficiency — protecting both your indoor air quality and your energy savings over the system's life.
From design to fully commissioned
One partner handles every step. Here's how we do it.
Fresh-air & load assessment
A Denair engineer calculates your Brooklyn building's ASHRAE 62.1 fresh-air requirement and surveys duct routing and mechanical space to determine the right ERV size and placement.
System design & equipment spec
We spec the ERV core, fan sizing, and controls integration, confirming compatibility with your existing HVAC and BAS before ordering equipment.
Fixed-price proposal
You receive a clear, itemized quote covering equipment, ductwork, and controls integration before installation begins. What we quote is what you pay.
Install & commissioning
Certified technicians install the unit and ductwork, then commission airflow, energy recovery performance, and controls sequencing before handoff — with documentation for your records.
