What We Do

Our Commercial Kitchen Make-Up Air Unit Repair Services in Long Island City

Comprehensive repair, maintenance, and compliance support — keeping Long Island City restaurant kitchens code-compliant and running.

🔧

Emergency MAU Repair

When your kitchen's make-up air unit goes down mid-service, your exhaust hood can't legally operate. Our certified technicians reach Long Island City restaurants typically within 4 hours, stocked to diagnose and repair on the first visit.

🔥

Gas-Fired Burner & Ignition Service

Most commercial kitchen MAU units run on gas-fired burners — we diagnose ignition failures, burner faults, and airflow sensor issues that trip your unit into lockout mid-shift.

📅

Preventative Maintenance Contracts

Custom maintenance plans starting from $396/year keep filters, belts, and burners in Long Island City kitchens tuned ahead of health inspections and busy seasons.

🌿

LL97 Compliance Optimization

A poorly tuned MAU unit wastes significant energy conditioning outside air. We assess your kitchen's carbon exposure and implement HVAC-side fixes that reduce fines under Local Law 97.

🔄

MAU Replacement & Upsizing

When a unit is beyond economical repair — or your kitchen has grown past its original design — we handle full replacement, engineered to your current exhaust hood CFM requirements.

📋

Code Compliance Documentation

We provide the service records and compliance documentation Long Island City restaurants need on file for FDNY, DOH, and insurance inspections.

LL97 Note: Long Island City buildings over 25,000 sq ft face escalating carbon penalties starting 2024. Make-up air units are often a hidden energy drain — tuning and controls upgrades are among the fastest ways to cut your kitchen's emissions footprint.

From breakdown to back online

One partner handles every step. Here's how we do it.

Same-day site assessment

You call, we respond. A certified technician reaches your Long Island City kitchen within 4 hours — equipped with common MAU parts to resolve most issues on the first visit, before your next service rush.

Root cause diagnosis

We check burner ignition, airflow sensors, belts, and controls together rather than replacing parts blindly — identifying the actual failure so it doesn't resurface next week.

Fixed-price proposal

Before a wrench turns, you receive a clear, itemized quote. What we quote is what you pay — no surprise charges after your kitchen is already back open.

Certified repair & commissioning

Factory-certified technicians complete the repair to OEM specification, then verify airflow balance against your exhaust hood before we leave — so your kitchen passes inspection, not just looks fixed.

Questions we hear every day

Straight answers about commercial kitchen make-up air unit repair in Long Island City — no marketing fluff.

How fast can Denair respond to a make-up air unit failure at a Long Island City restaurant?

Denair provides 24/7 emergency response across Long Island City, with technicians typically on-site within 4 hours of your call. Because a failed MAU unit usually means your exhaust hood can't legally run — and your kitchen can't legally cook — we prioritize commercial kitchen calls and stock common MAU parts on our service vehicles to resolve most failures same-day.

Is Denair familiar with the specific MAU brands used in restaurant kitchens?

Yes. Denair services and repairs make-up air units from Trane, Carrier, Reznor, Greenheck, and other major manufacturers common in Long Island City commercial kitchens. Our technicians are factory-trained to diagnose gas-fired burner assemblies, airflow interlocks, and control boards to OEM specification, protecting your equipment warranty.

How does make-up air unit repair relate to Local Law 97 compliance?

LL97 caps carbon emissions for buildings over 25,000 sq ft, and MAU units — which condition large volumes of outside air — are often a significant, overlooked energy load. A failing or poorly tuned unit burns more gas and electricity than necessary, increasing your building's emissions. Denair includes an LL97 impact review with major MAU services for qualifying Long Island City buildings.

What does make-up air unit repair cost for a Long Island City restaurant?

Cost depends on the specific failure — a burner ignition module or airflow sensor repair costs meaningfully less than a blower motor or heat exchanger replacement. Denair diagnoses the issue first and provides a fixed, itemized quote before starting work, so you know the full cost before we touch the unit — no hourly surprises during a service rush.

Can a make-up air unit repair be done without shutting down my kitchen?

In many cases, yes — if your kitchen has any backup ventilation or the repair can be staged during off-hours, we schedule around your service times whenever possible. For units that are the sole source of make-up air, we prioritize same-day diagnosis and repair specifically to minimize the time your Long Island City kitchen is out of code-compliant operation.
