Furnace Repair: Furnace has Noisy Operation

Gas Furnace Has Noisy Operation

Signs you're in need of furnace repair can be as simple as listening to the furnace while it's running - just like a car. If you notice the furnace is making excessive noise while operating, you should call Climate-Tech right away.

Possible Causes

1. Higher pitched "squealing" sound may be caused by slipping blower belt or motor or shaft bearings in need of oiling
2. Lower pitched "rumble" sound may be caused by a poorly adjusted pilot light if this problem occurs with the burners off
3. Lower pitched "rumble" sound may be caused by dirty gas burners if the problem occurs with the burners on

Possible Repairs

1. Oil blower motor lubrication ports (usually at each end of shaft) with light weight oil
2. Check for proper belt tension. Belt should depress about 1" at center of span
3. If too loose, tighten belt
4. Replace frayed belt
5. Adjust pilot light
6. Call furnace service technician to have burners adjusted or cleaned
