I was out inspecting another system from a janitorial company stating they were IKECA certified. IKECA has never heard of them and here are pictures from the job. Make sure you call IKECA to verify if your cleaning company is indeed certified AND is a member. Certification only means they passed the test. Active members promise to adhere to the IKECA and NFPA96 guidelines. The same goes with the Grease Police and other organizations. Make sure the company you are using or considering to clean your grease exhaust vent systems are ACTIVE members of a certification organization who have promised to adhere to the organizations guidelines. The attached pictures speak for themselves. The job was just cleaned 2 days prior.
