Question about Heating & Cooling
I bought and installed the unit today. When first turned on everything starts up fine, nice cold air and all. After a few moments though the units lights will all flash at the same time while it also makes a beep and then everything turns off. Then it kicks back on minus the cold air part. It sounds like the compressor is not starting, because it is not so loud once it starts back up after its little sequence. If I leave it one to see if it ever starts back up again it does not, but it does every few moments go through that same sequence of events. If I turn it off, and leave it off for a while, I can then turn it on and the air is cold again and runs fine, until the dreaded sequence rears its ugly head yet again.

I'm willing to bet the unit is not draining properly. Be sure it is level or pitched outside and the water is draining. Good luck.

There are a couple possibilities:
1. If this is the first time you've started them for the season, one of the compressors might be seized up from sitting over the winter. In which case, new compressor required.
2. If you've just had the compressor serviced including recharging the system, it's possible that the system is simply overcharged. This will stop the compressor from working and giving you the same symptoms as above. If this is the case, you should have the service people come back with some guages and recover some of the refrigerant and the compressor should be fine.
3. If the unit has been sitting and there is a slow leak then there is not enough pressure in the system to allow it to run. The compressor will shut down if there is not enough pressure, but since you say there is a smell, i really doubt this is the case.
Most likely it's #1 or #2 above. If you haven't had it serviced recently, then yeah, it sounds like you're in need of a new compressor.

I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.

A screeching or squealing noise usually comes from the fan motor. There may be an oil port and you can buy a small telescoping oil bottle at a super hardware store or an a/c supply house. Before putting in he oil, remember to TURN OFF THE POWER TO THE UNIT and only use a light squeeze on the bottle - over oiling will cause a mess inside the motor. It may be a sealed motor and no oil ports. In either case, budget for a new motor as if it's to the squealing stage, the bearings are already damaged and it's a just matter of time before before the motor bearings fail. If possible, get oil on the bearings ASAP - and use the proper lightweight oil for made for this application.
