My family and I love to visit a small restaurant in our town about once a week.
The food there is great and they always have their air conditioning or furnace set at the perfect temperature.
Unfortunately, the restaurant burned down last night. The cause of the fire was unclear, but some say it had to do with their HVAC system malfunctioning. The next night another small restaurant burned down and no one knew how the fire started, but there were rumors going around that someone was messing with the heater system which caused it to start a fire. Since I work for our town’s HVAC company, I was sent to go inspect the HVAC units in these restaurants to see if I find anything wrong with them. I visited the first restaurant and took the HVAC unit apart. I checked the air conditioner side of the unit and it seemed like it was in perfect condition, but when I checked the heating unit, I discovered something very interesting. Someone had put some very flammable fumes in the heater and caused it to start a fire in the air vents of the restaurant. When I inspected the air conditioner and furnace of the second restaurant that burned down, I found the same problem. I had several of my HVAC friends inspect the other HVAC units in other restaurants around town, and we found out that someone had done this to several heaters in other areas. After doing some searching, the criminal was found and all the HVAC units were fixed and restored to their proper place. From that time on, the town remembered this event as the HVAC heating incident.
