Furnace repair men, HVAC technicians, and plumbers can kill people part 1 was released five years ago by “Cleveland Home Inspector” Marko Vovk. Since that video, thousands of US HVAC contractors went back to school and became combustion certified and now these HVAC contractors actually save peoples lives. This part 2 video is truly amazing. If you are going to put your company sticker and phone number on a gas appliance, first make sure that this gas fired hot water heater, furnace or other appliance is not going to kill somebody. In this video, this home’s rooms did not have cold air returns. The only single cold air return was located in the l furnace and hot water heater closet. When you turn on the furnace in this home, the furnace sucks all the air out of this very small utility closet. This small utility closest also has a gas hot water heater. The two small make-up door registers located on the closet doors and the one small register located in the upper wall are simply not enough. These small door registers are supposed to help bring fresh air into this small utility room. The cold air return on the furnace sucks all the air out of this room causing major negative pressure. This negative pressure is so extreme, that make up air comes back down the chimney flue, and spills out of the water heater vent draft hood. This causes water heater exhaust fume spillage, burner chamber oxygen depletion, and incomplete combustion, which all result in CO carbon monoxide production. When somebody dies in this home, the survior may have a lawsuit. All they have to do is call their lawyer and give the law firm the name and number on the sticker. This particular contractor had a sticker on the furnace and hot water heater. If you are going to put company stickers on gas appliances that you install, repair, or maintain, make sure they don’t kill or make people sick. To repair this, you need to add cold air retunes to several rooms, slightly pressurize the utility closet, change utility closet doors to louvered doors, and buy a low level carbon monoxide detector.
