What We Do

Our Make-Up Air Unit Service Services in Manhattan

Emergency repair, maintenance, and code compliance service — keeping the make-up air units behind Manhattan's commercial kitchens balanced and running.

🔧

Emergency MAU Repair

When a make-up air unit fails, your kitchen exhaust hood can trip an interlock and shut down cooking operations. We reach your Manhattan site typically within 4 hours to get you back open.

🍳

Kitchen Exhaust-Linked MAU Balancing

We balance make-up air volume against your exhaust hood's actual CFM, correcting the negative pressure and comfort issues common in Manhattan restaurant kitchens.

🔥

Gas-Fired Burner Service

Full diagnostic and repair of gas-fired burner and ignition components — the most common point of failure in commercial MAU systems.

📅

Preventative Maintenance Contracts

Scheduled inspections ahead of your busiest service periods, catching burner, belt, and filter issues before they become a mid-shift shutdown.

✅

DOB & FDNY Code Compliance

We service and document MAU systems to the standards Manhattan's health, fire, and building inspectors expect — reducing the risk of a failed inspection.

🌿

LL97-Linked Ventilation Efficiency

Undersized or poorly balanced make-up air units force other HVAC equipment to work harder. We assess how your MAU affects overall building energy use and LL97 exposure.

LL97 Note: Manhattan buildings over 25,000 sq ft face escalating carbon penalties starting 2024. Properly balanced, well-maintained make-up air units reduce strain on the rest of your building's HVAC plant — ask us about your building's exposure.

From shutdown risk to balanced airflow

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

Same-day site assessment

You call, we respond. A certified technician reaches your Manhattan location within 4 hours, equipped with diagnostic tools and common MAU parts to resolve most issues on the first visit.

Root cause diagnosis

We check the burner, blower, belt, and controls together — identifying the actual point of failure rather than a quick patch that fails again during service.

Fixed-price proposal

Before a wrench turns, you receive a clear, itemized quote with no hidden line items. What we quote is what you pay.

Certified repair & airflow verification

Technicians complete the repair to manufacturer specifications, then verify make-up air volume is properly balanced against your exhaust system before we leave.

Questions we hear every day

Straight answers about make-up air unit service in Manhattan — no marketing fluff.

How quickly can Denair respond to a make-up air unit failure in Manhattan?

Denair provides 24/7 emergency response across Manhattan with technicians typically on-site within 4 hours of your call. Because a failed MAU can trip a kitchen exhaust interlock and stop cooking operations, our dispatch treats restaurant and commercial kitchen calls with urgency, with common burner, blower, and control parts already on the vehicle.

Does Denair balance make-up air against our exhaust hood, or just repair the unit?

Both. A repair that ignores the balance between make-up air volume and exhaust CFM often leaves the underlying comfort or negative-pressure problem in place. We verify and correct this balance as part of standard service, not as a separate add-on.

How does make-up air unit service relate to NYC Local Law 97 compliance for Manhattan buildings?

LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and an undersized or poorly balanced make-up air unit forces the rest of a building's HVAC plant to work harder to maintain comfort, increasing energy use and emissions. Denair includes a ventilation efficiency review with major MAU service for qualifying Manhattan buildings.

What does make-up air unit repair or maintenance cost in Manhattan?

Cost depends on unit size, whether the issue is the burner, blower, belt, or controls, and rooftop access requirements. Most repairs are quoted as a fixed price after an on-site diagnostic. Restaurants and commercial kitchens typically benefit from a maintenance contract timed around their busiest service periods.

Can Denair service make-up air units for restaurants specifically, including FDNY-related requirements?

Yes — we regularly service kitchen-linked MAU systems for Manhattan restaurants, documenting service to the standards that health and fire inspectors look for, and coordinating with your hood cleaning vendor when an issue is tied to interlocks or exhaust system condition.
