Squeaky Air handling unit

Something within my air handling unit has started squeaking loudly. I assume that it is the blower. Is there some way to lubricate the blower to correct this problem? Thanks.

Joe,
You should be lubricating various parts in your heating system. Call your heating guy and schedule a routine maintenance and fix the squeak visit. Have him clean and check both the furnace and AC. Shouldn't be expensive unless the motor bearings are shot or he finds other problems.

Depending on the specific motor used. Lubrication now is just forstalling the replacement of the motor. Call a pro and have it checked out. Or take it apart until you find the problem and fix it. It could be the blower wheel has become loose and moved into contact with the housing.
FYI geting at this may be an excersize in your patience.
I had a VFD go out in a American Standard once. It took me 2 hours to get the houseing out of the cabinet. 1 hour to disconnect it. 1 hour to go to the wholesale house and get the part. And 2 hours to replace it. Sure glad I do not make my living at this. ( No A/C company would touch the job for 3 days. )

Could be the blower bearings, motor bearings, belt worn or loose. If you are unfamiliar with all of this, have a service tech come check things out and watch what he does. He will probably check other thinks, like the burner, ignition, etc. A little PM today can save big repairs later.

Thanks for the tips. I hate to call anyone out, because I assume that they will find something wrong regardless of whether or not their truly is. I'll check it out and see if I can find an oil port first then I'll make the dreaded call I suppose. Joe

Mine was squeaking also, so I took the blower out. Then removed the motor and motor mounts and blower wheel out. Then I cleaned of everything thourghly (took several hours, and did it mostly in my laundry tub). Put everything back togather and now no noise after more than a week. Cleaning out the blower wheel was the most difficult part (getting inbetween the blades with a toothbrush took some time).

I wonder if there is an easier way to do that operation? That tooth brush routine sounds a bit tedious.

We had a squeaky one also, turned out to be a thumb screw that holds the damper in place.
