System is working at this time, performed second check up to verify. Inducer motor is slightly hot to touch and is starting to show age, as is system as a whole though. However it checks out good at this time. Found a few screws that were loose which could have caused a strange noise, tightened each one on system. Door at one point had a mild high pitch noise due to air pulling through it. Sealed door inside with tape to eliminate any future airflow noises.
