Tech arrived to no heat call for entire location. This is a office building with residential equipment. System is zoned for entire space. System is roughly 21 years old. Inspected system. On arrival, inducer motor ran as intended but system never moved to ignition phase. Removed inducer tubing and found inducer port clogged with debris. Removed debris and watched operations. After a few minutes of runtime, inducer motor started making a loud grinding noise as if the bearings are going bad. System does not have any safeties whatsoever. Highly recommend water safeties as well. Found upstairs damper motor not operational. Brought recommendations to customer. At this time, property owners have not responded back so only cleaning the inducer port was done today. Inducer motor may give out in due time and upstairs damper motor has failed. System is operational for today but permanent repairs need to take place soon. Thank you for letting TE CERTIFIED service your home.
