Sounds like the fan bearings are shot. When it starts to squeal, It is
usually too late to oil it. However, you can try if it has oil ports
on the side of the motor. Add 20 drops of 20 or 30 weight
non-detergent motor oil to each port. DO NOT use WD40 or sewing
machine oil or penetrating oil. Use a squeeze bottle with a small
nozzle on the end to get the oil in.

If that doesn't help, you are looking at $200.00 to $350.00 depending
on rates in your area. Should take 1.5 to 2 hours to diagnose and
replace the motor. You will pay more if the fan blade cannot be
reused.

A squeal doesn't necessarily mean the bearing is
shot. And, $200 to $350 for a motor is a rip off.
What is to diagnose? it either continues to
squeal after adding oil or it doesn't.
Replacement, at least in my unit, shouldn't take
more than 1/2 hour start to finish no matter how
klutzy one is--unplug the fan wires and remove a
few bolts.



Yea...ok.
How about a two speed Trane, or York fan? American Standard two speed?
Wholesale is over $200 for those.
What about a Carrier OEM motor? Totaline LOVES those...almost $150 for one.



If the oil doesn't fix the OP's fan and the OP has
any mechanical skills, he ought get the model
number, go to a parts place and order the motor
(and fan blade if needed), and replace it himself.

Glad I don't live where you are. It only cost me
$50 bucks to have a tech check the gas pressures
and voltages/amps, add a little bit of gas, and
oil the motor. Took about 20-25 minutes, most of
which he spent talking to me and answering my
questions.



No way he did it correctly then, since in order to " add gas" properly, you
have to check subcool, or super heat and this takes at least 15 minutes to
do properly. Then, after adding, he has to recheck it again. BTW, the
pressures mean NOTHING. Nada....One of my guage sets does not even have
pressures on it, but temps, depending on the refrigerant in question.
Hint...its not the pressure that matters as much as the temps of the
refrigerant in question, based upon the superheat, or subcool.

He stole your $50 man....even if you think its working fine, he stole your
money....reached right in your pocket and stole it.
20 minutes for $50...hes charging over $100 per hour for stealing.
Damn..I gotta raise my rates since we do it right....


So what makes you think he didn't check the temps?
All my wife told him was that it didn't seem to
be cooling quite right after she heard a gurgle.
(personally I didn't agree with my wife but it did
seem to cool a bit better).

How do you check the subcool and the super heat?
Do you go inside? I've never seen an AC guy check
a unit by going inside the house! Hell I don't
know exactly what he did.

Maybe he was here more than 25 minutes. How about
35 minutes, would that satisfy you? No? need to
be 45 minutes, may an hour would be better. Not
enough money yet for a simple problem? How about
an hour and a half?

Ok, I would be more satisfied if he was here for
an hour and a half and charged me $200 and added 2
pounds that I didn't need. Hows that!.
