I got hot air and some smoke come from my exhaust fan. My kitchen in food court and a kichen exhaust fan connect to the main building exhaust fan.
4 days ago, the shopping centre got problem with air conditioning, the hot air started to blow into my kitchen at that time. Now they fix the air conditioning but the hot air is still blowing into my kitchen. Other shops don't have this problem when they turn off their exhaust fan but I do have hot air when I turn off my exhaust fan. Also, the cooking smoke doesn't suck in very well when I turn on my exhaust fan. It seems like the air can't get through the building roof.
Anyone know How I can deal with this. The centre people "Trying to smart ASS" say that only my kitchen's problem.
