Owner Dan Oboyle guides us through an installation of a commercial kitchen exhaust system at a restaurant called TreMonte. The previous exhaust system was 15 years old, the newer system is larger and has dual openings. Old exhaust systems cause bad air for the employees and the patrons. All permits are put in place, the heavy equipment, the list, the welding, the fire suppression system, and the new hood and duct work. You can see brand new ceilings, stainless steel panels, new hood, new duct work, new fire suppression system, and overall; a great new kitchen.
