How does it works with the air conditioning system? Is fan coil unit similar to split unit?

We have all enjoyed the cool breeze coming out of an air conditioning vent, but chances are you haven't stopped to consider just how an air conditioner is able to cool down the air inside. What follows is a general overview of the process.
The main components of any air conditioner are a compressor, two sets of coils filled with a refrigerant (generally referred to as Freon), and an expansion valve, all connected in a circular fashion. The Freon, which takes on both liquid and gas forms, follows the following cycle:
* Freon gas enters the compressor. The compression process heats the Freon, changing it into a high-pressure hot Freon gas.
* The hot Freon gas is released into the first coil. The high pressure causes the gas to move along the expanse of the coil, which is located on the outside of the building. Over the course of this journey, the Freon gas begins to cool as a fan causes the outside air to absorb the heat. The newly-cooled Freon gas converts into cool liquid Freon.
* The cool liquid Freon enters the expansion valve, where it is converted back into a cooled Freon gas and released into the second coil. The second coil is located on the inside of the building.
* Air from inside the building is blown by a fan against the second coil, which contains the cooled Freon gas. The Freon gas absorbs the heat from the air, causing the air to cool and the Freon gas to start to heat up again. The newly-cooled air is released back inside the building.
* The process repeats as the Freon gas enters the compressor once again.

Freon is a substance which has a really low boiling point, but you can compress freon gas so much that it becomes a liquid. By compressing a gas, you heat the gas up (this is a law of physics).
So, if you take freon gas and compress it, what you'll have is a really hot liquid. But the amount of energy contained in this hot liquid is the same as the cool gas - it's just that the compression itself "intensifies" the energy, if you will.
Leave the closed can of compressed freon until it cools off. Because of the cooling, the liquid freon loses a lot of energy.
Now, open up the can. What happens is that the drop in pressure causes the freon to boil furiously, as it tries to return to the gas state. In the same way as the freon heated up from gas to liquid, it cools off dramatically when going from liquid to gas. Because the liquid freon was already room temperature, the gas cools down to icy cold temperatures.
Now, all you need to do is build a system which catches and compresses the freon again, so the nasty stuff doesn't excape into the atmosphere.

Something doesn't sound quite right - especially about the Freon (fyi: freon is just a brand name for refrigerant). Since you're Canadian R22 is still a very popular refrigerant there (and systems will be manufatured in the US with R22 until the year 2010) and mostl likely unless your A/C is over 10 years old R22 is the refrigerant used. If it's over that in age it could be R12 and R12 is extremely expensive. Depending on how low the charge was in your system, the price he charged may not be too far out of line. You also don't say if it's a window unit or a central system. The average going rate in the US for labor on hvac systems is $70 to 90 US per hour. I don't have the exact conversion rate handly but I'm guessing $100 to120 Canadian wouldn't be to far off, so if he worked about 90 minutes, that labor charge would be about right. As far as the capacitor goes, one about the same isn't the same as one exactly the same. If you still feel like you got ripped off, call the servicing company and ask them to explain the charges in detail.

i know how it works, compressed it takes heat away and expands to cool, similiar bvut not the same as water off your skin/ you should also have a condensor unit and a evaporator unit oon all air conditioners along with the fan and the compressor

What happens if you heat it up to lets say 115ºF, or 95ºF?
