What We Do

Our Make-Up Air Systems Contractor Services in Long Island City

Design, installation, and ongoing service for the make-up air systems balancing exhaust in Long Island City’s residential and commercial buildings.

📐

Make-Up Air System Design

We engineer make-up air systems sized to your exhaust load — kitchen hoods, bathroom exhaust, or industrial ventilation — rather than defaulting to oversized, wasteful equipment.

🏗️

New Construction & Retrofit Installation

From ground-up installation in new Long Island City developments to retrofitting outdated units in older buildings, we handle full turnkey installation.

🚨

Emergency Service & Repair

A failed make-up air unit throws building pressurization out of balance fast. Our technicians typically reach Long Island City sites within 4 hours.

📝

NYC DOB Filing & Code Coordination

We manage the permitting and inspection process for new make-up air installations, so your project moves through NYC DOB without delays.

🌿

LL97 Efficiency Engineering

Make-up air units are significant energy consumers. We specify high-efficiency equipment and controls that reduce operating costs and carbon exposure from day one.

📊

Commissioning & Balance Reporting

Every installation concludes with certified test-and-balance reporting, confirming your system meets design specification and NYC code requirements.

LL97 Note: Long Island City buildings over 25,000 sq ft face escalating carbon penalties starting 2024. Specifying high-efficiency make-up air equipment with modulating controls at installation is one of the most effective ways to keep long-term LL97 exposure in check. Ask us about your building’s exposure.

From design to commissioned system

One partner handles every step. Here’s how we deliver your make-up air project.

Load & exhaust assessment

A certified engineer surveys your Long Island City building’s exhaust systems — kitchen hoods, bathroom fans, industrial exhaust — to calculate true make-up air requirements.

System design & equipment specification

We design a system sized to your actual load, selecting equipment and controls that balance performance with long-term energy efficiency.

Fixed-price proposal & permitting

You receive a clear, itemized quote before work begins, and we handle NYC DOB filing coordination so your project isn’t delayed by paperwork.

Installation & commissioning

Certified technicians complete installation and full system commissioning, verifying airflow balance against your exhaust systems before signoff.

Questions we hear every day

Straight answers about make-up air systems contractor in Long Island City — no marketing fluff.

How quickly can Denair respond to a make-up air system issue in Long Island City?

Denair provides 24/7 emergency response across Long Island City with technicians typically on-site within 4 hours. For new installations and larger projects, we work on a scheduled timeline coordinated with your building’s construction or renovation schedule.

Does Denair handle new construction make-up air installations, not just repairs?

Yes — Denair is a full design-build contractor for make-up air systems, handling everything from initial load calculations and equipment specification through installation, NYC DOB filing coordination, and final commissioning for both new construction and retrofit projects in Long Island City.

How does make-up air system design relate to NYC Local Law 97 compliance?

LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and make-up air units — which often run continuously to balance kitchen or industrial exhaust — are a significant piece of a building’s energy profile. Specifying high-efficiency equipment with modulating controls at the design stage is one of the most effective ways to control long-term LL97 exposure. Denair includes an LL97 impact assessment with every new system design for qualifying buildings.

What does a make-up air system installation cost in Long Island City?

Costs depend heavily on system size, ductwork routing, and whether it’s new construction or a retrofit into an existing building, so we provide a detailed, fixed-price proposal after our initial load assessment rather than a generic estimate.

Can Denair size a make-up air system correctly for our building’s exhaust load?

Yes — correct sizing is the foundation of every project we design. We calculate your actual kitchen, bathroom, and industrial exhaust load before specifying equipment, avoiding the oversized, energy-wasting systems that result from guesswork sizing.
