Performed furnace start up; inspected the exhaust and intake PVC ensuring all connections were secured we will have to return to replace a section of pvc that is leaking water as well as spray foam the intake and exhaust, I then sniffed the gas line for possible leaks, I did find that the evaporator coil is slanted the wrong way this could cause issues during AC season we’ll follow up with this, I did inspect gas pressures and did adjust it to 3.5InH2O, as well as performed a combustion test verifying no CO in the airstream. This system is currently operating normal and heating at 34 degrees at this time Job complete
