SOURCE: Loud screeching sound coming from the unit

It sounds like the fan motor needs lubricating. Do you need help with this?

sounds like a locked rotor, did the compressor get hot? did you check max amps on the compressor when it attempted to start?compressors have thermal protection built into their windings, a switch that will open to protect the compressor, and if the rotor is locked, normally you have to replace it, you could try putting what is called a start assist capacitor on it (AKA hard start kit) I would recommend the two wire model, easy to install.
You will need to wait for the thermal overload to reset, turn power off to unit till you get the kit on there.

Frigidaire fac127s1a is really loud - 70db+ - any fix available?

You might be able to find a sound insulating blanket that wraps around compressor. Check with a Carrier or York dealer. Most brands use the same compressors so you might be able to score one.

Craftsman Air Comp. 6 hp oil-less, 33 gal horz. tank - sounds really loud

Some of the craftsmen compressors have pistons that are coated on the top of the dome. Once the coating wears off, they have severe loud piston slap. If you continue to run it the way it is, it will snap the connecting rod in half or break the piston and possibly the cylinder.

When my newly installed sqaure d 30 Amp definite purpose 120v coil pulls in it makes a loud humming noise. This noise is louder at times, and sometimes seems to make no noise and perform properly. The...

Hi and welcome to FixYa I am Kelly. The humming your hearing is the contacts on the contactor relay. They are floating contacts. Due to the fact that they float depending on the position they closed in you may or may not get a hum. Over time it may or may not snap out of it as the contacts get some use wear on them. Usually they do. Sometimes they never do. It is not a bad thing unless you notice the contactor heating up. Often by the time you notice the heat build up it is too late. The heat build up is cause from loose floating contacts. There are springs above the contacts that hold the contacts together when the contactor is energized.

If your really believe that your contact is making way too much noice I would go to the purchasing source for your contactor and discuss your concern. They may or may not replace your contactor. It is a judgement call on your part. I would at least try cycling it on and off several times and see if it snaps out of it. If it never does.... go see the purchasing source and have a conversation about what your contactor is doing.

Thanks for choosing FixYa.

We're changing a compressor and want to see relationship between the capacitor contactor and other things

The capacitor aids a unit in starting and then in running.

the contactor is a switch that tells the compressor when to come on. It is usually controlled by another voltage. So the low voltage control circuit powers a coil in the contactor, which in turn, energizes the contactor, thus closing the contacts to turn on the compressor.

A/C unit air handler comes on inside but outside compressor does not come on. The contacts are not working. If I hold down the contacts the compressor comes on and unit works.

Check and find out if you have 24 volts across the terminals for the coil of the contactor. If you have 24 volts across the terminals and the contactor does not pull in change the contactor with one of the same ratting. If you do not have 24 volts across the terminals for the contactor coil your problem in in the 24 volt circuit. Possible that the thermostat is not sending power to the contactor through the "Y" terminal.
