Make-Up Air Units & Air Handling Units

A kitchen exhaust hood removes a lot of air. If that air isn't replaced, doors slam, hoods stop pulling smoke and grease, and the dining room gets uncomfortable. Make-up air units (MUAs) and air handling units (AHUs) keep commercial spaces balanced, ventilated and comfortable. Liberty HVAC installs, replaces and services MUAs and AHUs for restaurants, offices and commercial buildings across Brooklyn, Queens, the Bronx, Staten Island, Manhattan, Nassau and Westchester.
