We were up for our annual cleaning of th range hood at my church. Because of the pandemic, we haven't used it in over a year. They were willing to just come out and do an inspection to make sure everything was working properly. The technician noticed not a lot of air movement above the stove and when he went on the roof, he took the cover off to verify that the fan belt was still on, it was. I appreciate the extra effort to make sure we were safe.
