Furnace wasn’t operating upon arrival. I started my diagnostic and found the spark igniter module failing. System couldn’t turn on heat, just fan spinning only. The blower motor is in bad condition and is unbalanced. You can hear the bearings of motor moving while system on. The motor using high amps while running, and system can’t operate how it used to. Looked into Rudd air conditioning equipment and they no longer make nor sell parts from distribution or distributors. System is from 1985, system needs to be replaced. Just charging for diagnostic today, after calling distributors and them verifying systems parts aren’t made anymore due to old age.
