ERV retrofits

for Long Island City
fresh-air performance

Denair provides 24/7 emergency response across Long Island City with technicians typically on-site within 4 hours of your call for existing ERV systems in distress. For new retrofit projects, we schedule site assessments within a few business days of your initial inquiry.

Yes. Many of our Long Island City ERV projects involve integrating new energy recovery ventilation into buildings that were never designed for it — coordinating ductwork routing, shaft space, and structural constraints that are common in the neighborhood's converted industrial and pre-war stock.

LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and conditioning outdoor air is one of the largest energy loads in ventilation-heavy buildings. An ERV recovers a significant share of that energy from exhaust air before it's lost, directly reducing the load your HVAC system has to condition. Denair includes an LL97 impact assessment with every ERV retrofit proposal for qualifying Long Island City buildings.

Cost depends on unit capacity, ductwork complexity, and whether we're integrating into existing infrastructure or adding new distribution. Denair provides a fixed-price proposal after a site assessment, and we can also structure phased retrofits for buildings managing a multi-year capital plan.

Yes — we offer preventative maintenance contracts covering core inspection, filter changes, and controls checks so your ERV keeps delivering its rated recovery efficiency long after installation, rather than degrading unnoticed.
