Whether in-home or commercial, kitchens require an exhaust hood and duct system to vent air. Hot air and vapors from cooking are vented up through the hood and out of the building through the kitchen’s duct system. Without this system, the kitchen can become overheated, filled with smoke and stained with grease. However, proper maintenence of the duct system is equally important – a clogged kitchen duct can cause the same issues mentioned, but can quickly turn more serious. Trapped grease and heat can ignite causing fires, damaging the entire system and possibly even the building itself. Following these simple tips can help you maintain a clean, efficient kitchen exhaust.
