What We Do

Our ERV Retrofit Services in Manhattan

Feasibility, design, and installation — bringing energy recovery ventilation to Manhattan buildings without a disruptive gut renovation.

📐

ERV Feasibility & Design

We assess your Manhattan building's existing ductwork, mechanical space, and ventilation load to design an ERV retrofit that fits without a full mechanical overhaul.

🔄

Energy Recovery Core Replacement

For buildings with aging or underperforming ERV cores, we replace the recovery wheel or plate core to restore efficiency without replacing the entire unit.

🔌

Ductwork Integration

New supply and exhaust ductwork is routed to integrate cleanly with your building's existing systems, minimizing disruption to occupied spaces during installation.

⚡

Controls & BAS Integration

ERV units are tied into your building automation system so ventilation rates adjust automatically with occupancy and outdoor conditions, rather than running at a fixed rate.

🌿

LL97 Compliance via ERV

Energy recovery ventilation directly cuts the heating and cooling load tied to fresh air intake — one of the more straightforward ways for Manhattan buildings to reduce LL97 exposure.

✅

Commissioning & TAB

Every retrofit ends with startup commissioning and a certified test-and-balance report confirming airflow rates meet design specification and code.

LL97 Note: Manhattan buildings over 25,000 sq ft face escalating carbon penalties starting 2024. ERV retrofits reduce the energy needed to condition fresh air — one of the more cost-effective paths to measurable emissions reduction — ask us about your building's exposure.

Questions we hear every day

Straight answers about erv retrofit in Manhattan — no marketing fluff.

How disruptive is an ERV retrofit for an occupied Manhattan building?

We design retrofits to minimize disruption by integrating with existing ductwork and mechanical space wherever possible, and we schedule noisier or access-heavy work outside business hours when needed. Most Manhattan retrofits are completed floor-by-floor or system-by-system rather than requiring a full building shutdown.

Is Denair certified to install and service energy recovery ventilators?

Yes. Denair's technicians are factory-trained on ERV systems and the broader HVAC platforms they integrate with, including Carrier, Trane, AAON, Daikin, and Mitsubishi Electric VRF systems — ensuring your retrofit is installed and commissioned to manufacturer specifications.

How does an ERV retrofit help with NYC Local Law 97 compliance?

LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and conditioning fresh outdoor air is one of the more energy-intensive parts of running an HVAC system. Energy recovery ventilation captures heating or cooling energy from exhaust air and transfers it to incoming fresh air, directly cutting the energy load — and the emissions — tied to ventilation. Denair includes an LL97 impact estimate with every ERV retrofit proposal for qualifying Manhattan buildings.

What does an ERV retrofit cost for a Manhattan building?

Cost depends on building size, existing ductwork condition, and how many units or floors are involved. We provide a fixed, itemized proposal after the initial feasibility assessment, so you can evaluate the payback against your specific energy costs before committing.

Can Denair integrate a new ERV with our existing building automation system?

Yes — we tie new ERV installations into your existing BAS wherever the platform supports it, so ventilation rates adjust automatically with occupancy and outdoor air conditions rather than running at a constant, wasteful rate.
