Heating - Hydronic Boiler in Union, NJ

Our technician returned to remove baseboard loop in the garage. Upon looking at the loop it was unable to be removed because the existing piping is currently connected to main floor zone. In order to remove the baseboard and reconnect the loop the garage wall would need to be cut open. The customer opted to keep the loop in the garage as is. The tech found the air vents were seized up and couldn’t bleed out the radiators. The new vents were installed and the heat was checked.
