Question about Heating & Cooling
It is 10 to 20 degrees outside so is that the reason or is something going out on the unit?
Check motor bearing may be need lubrication or damaged need replacement if sleeves need replacement

Most of the fan motors can be oiled. You will have the slide the ac forward and remove it from the case to access it. You will find yellow pull pins on each end of the motor, a lite drop or two is all that is needed.

SOURCE: I have a Samsung RS21DPSM
There is a design problem with this model. The fridge section is icing over due to a design defect and the noise you can hear is due to the fan on the motor driving against the ice. Eventually the motor will be stopped from running and the fuse will blow in your plug. Contact Samsung and they should replace the defective parts with a fix.

SOURCE: outside makes loud noise
I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

A bit late late for the date listed, but for future reference:
The condenser coils are easy to clean by simply rinsing them with a water hose with LOW pressure. Grass or sand can easily get sucked into the condenser coils (think of it a an oversized vacuum cleaner) and slowly decrease the machine's ability to shed the heat it is pulling from inside. If the coils are really clogged, follow this procedure: 1) Turn the thermostat to "OFF" and if others are around, tape a note over the thermostat stating "DO NOT TOUCH!!!", 2) outside on the wall there should be a disconnect box with a pull out power connector or a flip switch - pull out the power bar noting which side is up or flip the breaker to off. Be sure the main power to the condenser is off. 3) A few 1/4" or 5/16" hold the top on, including the fan. Remove the screws (note if any screws are longer than the others and mark where they went) and lift the lid (fan and all) up and if there is enough slack in the fan wires you may be able to lay it over, if not, use a stick to prop it up. 4) Use a LIGHT mixture of a alkiline cleaner like 409, Purple Stuff, etc. DO NOT USE ANY ACID BASED CLEANER! Soak the coil through (not just the outside) and let it sit for 5-10 minutes. 5) Use a garden hose and a spayer nozzle (but not with a hard stream as it may bend the fins on the coil) and THOROUGHLY rinse the chemical and debris out. Do not get any water or chemical into the electrical area! (While the lid is open, grab the fan by the hub (center) and give it a pull in each direction; there should be vitually no "play" on the shaft except a small amout up and down. If there play or grease visible, it probably won't be long before the motor gets hot and siezes). 6) Put the lid back on making sure the wires feed back into the electrical compartment and are fully out of the way of the fan blade and putting the screws back in snug making sure any longer screws go back to the same spot. 7) Turn the main power back on and start the a/c. For regular cleaning, just rinse the coils with a garden hose. Depending on the conditions maybe every 2 weeks with lots of sand blowing or mothly in a grassy area.
The fan motor: if it has oil/grease leaking it will fail at the worst time (Murphy's Law). Most warranty repairs have to be done by a licensed contractor. For any repair it's a MUST to do price shopping and reference checking. Sometimes it's better to pay 25% more for a company with a good reputation than a hacker that may even wire the motor wrong.
Bottom Line: Get a maintenance contract with a reputable company that will clean the air handler and condenser and check for weak components and not try to sell you a bill of goods. Never hire a company that does it for less than $50 per cleaning as they will try to sell you something you don't need or even sabatage your system (I've seen it all living in Florida) as it costs about that much just to put the truck on the road.

OK, you will need to replace this compressor. the internal seals have ruptured, causing the loud noises. the heat is from the metal to metal friction. the compressor can be rebuilt but, it will be more costly than just replacing it with a new compressor.
