Microfarad (and farad) is a unit for measuring capacitance of capacitors (in electricity). It cannot be related to horsepower. Many electric motors have capacitors to help them start under a load, though.
The hermetic compressor cannot use a centrifugal switch like an open motor because it will disrupt the start winding. Hermetic compressors work through insulated motor terminals, and not in the open.
Unless it's a zip type, you can't. If you mean to just store food, you can use a chip clip.

A surge arrestor helps prevent a voltage spike on your home electrical supply from damaging your electronics by shunting that voltage to ground. Here is an article that describes what the do and how to use them. http://handydandytips.googlepages.com/howtoprotectyourhomeelectronicsfromlight
To service a stuck Hermetic compressor,repair the start components of the air conditioning compressors.
Hermetic manufactured from special materials because Hermetic compressor motor materials must be compatible with the refrigerant and oil circulating in the system.

because the hermatic compressor motor must be compatible with the refrigerant and oil circulating in the system.
the compressor capacity will increase
because black body absorbs/emit maximum heat
The parts of a hermetic (sealed) reciprocating compressor is as follows; motor, crankshaft, bearings, valves, and pressure relief valve and piston(s). there are other smaller parts that can be named but these are the main players. The hermetic scroll compressor is a little different than the reciprocating compressor because it uses an orbiting scroll and a stationary scroll to compress the refrigerant instead of pistons. This is why a scroll compressor cannot run "backwards". The scroll compressor also has an oil pick up tube which differs from a reciprocating compressor. Now a "semi-hermetic" compressor is build like a small engine. It has an oil pump, reed valve plate, unloaders, pistons, bearings, etc. A screw compressor is in a class all to itself.

No the compressors in residential condensing units are called hermetic compressors and have to be rebuilt by cutting open the compressor shell, then rebuild the compressor and then weld the shell shut. Buy a new compressor or condensing unit.
Receip or Piston type compressor are used for large duty cycle work (A/c or other equipments), energy hungry but last longer (Heavy Duty). Where as rotary compressor are energy efficient with higher ( Energy Efficiency Ratio) but lower duty cycle and shorter life. Selection of compressor are based on the nature of application. Normally, for room A/Cs with capacity less than 3 ton, most companies offer rotary compressor due to it's EER and less duty cycle. For heavy duty A/Cs, recip or piston compressor best suited.
