Our Carrier MAU Services in Long Island City
Comprehensive makeup air unit maintenance, repair, and replacement — keeping LIC's commercial kitchens and industrial spaces properly ventilated year-round.
Emergency Carrier MAU Repair
When your Carrier makeup air unit fails, kitchen exhaust systems can't legally run and comfort suffers fast. Certified technicians reach LIC sites typically within 4 hours.
Scheduled MAU Maintenance
Custom-timed inspections ahead of LIC's cooling and heating seasons keep filters, coils, and heating elements performing before demand spikes.
Heating Element & Coil Tune-Up
Gas-fired and electric heating elements, along with cooling coils, are inspected and serviced to Carrier's OEM specifications for reliable year-round output.
Controls Repair & Calibration
Faulty MAU controls waste energy and undermine kitchen exhaust balance. We diagnose and recalibrate controls to restore proper airflow tracking.
MAU Replacement
When repair no longer makes economic sense, we handle full Carrier MAU replacement — engineering-grade spec, DOB filings, and startup commissioning included.
Air Balancing & TAB Reporting
Certified test-and-balance reports confirm your Carrier MAU is delivering the exhaust makeup air your kitchen or industrial space requires by code.
