Frequently Asked Questions:
Why Reheating Is Required In Air Conditioning,?
Reheat is used to control humidity to a specific level. Simple air conditioning will reduce the humidity but it doesn't control it to a precise level. In fact if the air doesn't warm up from the heat in the room, you could end up with 100 percent humidity. A rare but possible event.
By over cooling the air and then reheating and adding specific amounts of moisture (if needed) you can be assured of the humidity level to an exact amount.

What Causes A Air Conditioner To Ice Over And Freeze Up?
Either you need to clean/replace the air filter, or it's a bad design, or you are trying to cool the room to a lower temperature than the unit was meant to achieve.
Water condenses on the evaporator coils of an air conditioner for the same reason that water condenses on any object that is colder than the surrounding air. It happens in all air conditioners. A window unit should be designed so that the water runs out the back (i.e., outside the house) when the is properly installed (i.e., level). The evaporator of a central air conditioning system usually is connected to a pipe that carries the condensate to a floor drain.
If the temperature of the evaporator coils falls below the freezing point of water, then the condensate will freeze on the coils instead of running off. That happens when the air flowing through the evaporator is not warm enough or not moving fast enough to keep the evaporator temperature above freezing. If the problem is not enough air flow, that probably is because you haven't changed or cleaned the air filter in a long time. Change it or clean it (whichever is easier.)
If the unit is getting good air flow, then you'll just have to turn up your thermostat.
Why Is Air Conditioing Bad For Us And Environment?
Air conditioning will always be bad for the environment because it consumes a tremendous amount of energy - electrical energy. Electrical energy can be obtained from "renewable" sources - e.g. solar, wind, hydro etc. Now this energy could be used for more important purposes than keeping the pampered affluent comfortable. In any case this energy will get renewed only so long as the sun continues to send us an adequate amount of energy; we'll be all right for some hundreds of million years more!
However, the fact is that we are so prodigal and undisciplined in our use of energy that most of the energy needed for electricity comes from fossil fuels. Our selfishness is going to cause fuels created by the "bodies" of plankton for millions of years to disappear within the lifetime of our grandchildren, perhaps.
