We had a call from a customer in Denville, New Jersey because there was CO2 backing up into the home, which is very dangerous.


Our technicians checked the furnace and hot water heater and then went to the roof to inspect the chimney. The technicians discovered a huge bird's nest that was blocking the airflow for the furnace and hot water heater.
