Make-Up Air Unit Repair NJExhaust Makeup and Pressure Balance Repair
Fast repair for make-up air units, restaurant ventilation, kitchen exhaust makeup, and pressure balance problems throughout New Jersey. If your hood is pulling air out faster than the building can replace it, your comfort, safety, and operations can all suffer.
More Specific Than General Commercial HVAC
A commercial HVAC page covers heating, cooling, refrigeration, maintenance, and rooftop units. This page is for a narrower problem: the building is exhausting air through kitchen hoods or ventilation equipment, but the replacement air system is not keeping up.
Dimatic Control repairs the equipment and controls that bring that air back into the building. For restaurants, food service spaces, commercial kitchens, and other exhaust-heavy businesses, a failed make-up air unit can create pressure problems, code concerns, comfort issues, and lost operating time.

Make-Up Air and Exhaust Makeup Problems
Pressure Balance Problems

Signs Your Make-Up Air Unit Needs Service
Make-up air problems often look like building comfort or hood performance issues. If these symptoms show up when exhaust fans or kitchen hoods are running, the replacement air system should be checked.
Kitchen hood is running but smoke, heat, or odors still spread
Exterior or dining room doors slam, whistle, or become hard to open
Dining room gets cold or drafty when kitchen exhaust is on
Make-up air unit is loud, vibrating, or not starting
Breaker trips, motor overheats, belts slip, or dampers stick
Staff report headaches, poor airflow, or uncomfortable cook line heat

Call (908) 249-9701How We Diagnose Make-Up Air Failures
Confirm Exhaust and Makeup Air Operation
We check the make-up air unit, exhaust fans, hood operation, dampers, controls, filters, belts, motors, and obvious airflow restrictions.
Diagnose the Pressure Problem
A failed unit is not the only cause. We look for negative pressure, blocked intake paths, stuck dampers, bad sensors, control issues, and exhaust imbalance.
Repair the Failed Component
Depending on the issue, repairs may include belts, bearings, motors, fan components, wiring, contactors, dampers, filters, thermostats, or controls.
Test Building Air Balance
After the repair, we verify the unit runs correctly with the exhaust system so the kitchen, dining room, and entry doors behave normally.
