Our Emergency Make-Up Air Unit Repair Services in Long Island City
Rapid-response repair keeping make-up air systems running — and kitchens legally operating — across Long Island City.
24/7 Emergency Dispatch
A live dispatcher answers every call, day or night, and immediately routes a certified technician toward your Long Island City location — no voicemail, no waiting for a callback.
On-Site Diagnosis & Repair
Technicians arrive stocked with common MAU parts — belts, motors, sensors, gas valves — enabling most emergency repairs to be completed in a single visit.
Restaurant & Commercial Kitchen Priority
Make-up air failures shut down code-compliant kitchen exhaust, which can shut down your kitchen. We prioritize restaurant and food-service emergencies given the direct impact on operations.
Gas & Electric MAU Systems
Whether your unit is gas-fired or electric, our certified technicians diagnose burner, ignition, and control failures across the makeup air systems most common in Long Island City buildings.
LL97 Compliance Impact
A malfunctioning make-up air unit often forces exhaust fans to run harder to compensate, increasing energy draw. We help you understand how MAU repairs relate to your building's Local Law 97 exposure.
Post-Repair Documentation
Every emergency repair concludes with a service report documenting the failure and fix — useful for insurance, DOH inspections, and your building's maintenance file.
