What We Do

Our Make-Up Air Unit Repair Services in Brooklyn

Comprehensive repair, tune-up, and replacement coverage keeping Brooklyn's commercial make-up air systems running efficiently and in code.

🔧

Diagnostic & Repair

Ignition faults, blower failures, and airflow imbalance are the most common MAU issues. Our certified technicians carry the parts to resolve most failures on the first visit.

📅

Preventative Maintenance Plans

Custom maintenance schedules keep filters, belts, and controls in check before a Brooklyn kitchen or warehouse loses exhaust capability mid-shift.

🌬️

Airflow & Balance Verification

We test and rebalance make-up air against your exhaust rating, correcting the pressure issues that cause comfort complaints and code violations.

🌿

LL97 Energy Optimization

Make-up air units are energy-intensive by design. We tune heating and cooling output to avoid over-conditioning air beyond code minimums, reducing your carbon exposure.

🔄

Unit Replacement & Retrofits

When repair no longer makes economic sense, we handle full MAU replacement — engineering spec, DOB filings, and startup commissioning included.

📊

Code & Inspection Documentation

Every service visit ends with a written report — documentation your health inspector, fire marshal, or insurer may request.

LL97 Note: Brooklyn buildings over 25,000 sq ft face escalating carbon penalties starting 2024. Make-up air units are among the highest energy users in commercial kitchens and industrial spaces — regular tune-ups keep that load from quietly inflating your building's emissions.

From diagnosis to back in balance

One partner handles every step, from first call to final check.

01

Same-day site assessment

You call, we respond. A certified MAU technician reaches your Brooklyn location typically within 4 hours, equipped to diagnose and repair on the first visit.

02

Root cause diagnosis

We don't replace parts until we understand the failure — ignition, blower, or airflow — identifying the real cause rather than masking a symptom that returns.

03

Fixed-price proposal

Before a wrench turns, you receive a clear, itemized quote with no hidden line items.

04

Certified repair & balance check

Factory-certified technicians complete the repair, then verify exhaust/make-up air balance is restored to correct operating range before we leave.

Questions we hear every day

Straight answers about make-up air unit repair in Brooklyn — no marketing fluff.

What are the most common reasons a make-up air unit needs repair in Brooklyn?
The most frequent failures we see are ignition or burner faults, blower motor issues, and airflow sensor drift that throws off the balance between exhaust and make-up air. Our technicians carry parts for these common failures, which lets us resolve most repair calls in a single visit to your Brooklyn location.
Does Denair repair make-up air units for both restaurants and industrial buildings?
Yes — we service MAU systems across Brooklyn's restaurant kitchens, manufacturing facilities, warehouses, and commercial buildings of all types, with technicians trained across the major manufacturers used in each application.
How does make-up air unit repair relate to Local Law 97 compliance?
Make-up air units are one of the more energy-intensive pieces of commercial HVAC equipment, since they actively heat or cool outside air to offset what's exhausted. For Brooklyn buildings over 25,000 sq ft, an inefficient or poorly tuned MAU can meaningfully increase energy use — and therefore LL97 emissions exposure. We check and tune airflow and conditioning setpoints as part of every repair visit.
What does make-up air unit repair cost in Brooklyn?
You'll receive a fixed, itemized quote before any repair work begins. Cost depends on the specific failure — a blower motor replacement differs from an ignition control repair — and preventative maintenance plans starting from $396/year per unit are available to reduce the likelihood of costly emergency repairs.
Can Denair also replace a make-up air unit that's beyond repair?
Yes — when a unit has reached the point where repair no longer makes economic sense, we handle full replacement including engineering spec, DOB filing where required, installation, and startup commissioning, so your Brooklyn kitchen or facility gets a properly sized replacement rather than another patch repair.
