Air Conditioning works by exchanging heat from inside a construction to the outside air. To do this some very basic refrigeration ideas need to take place. One of the most critical pieces that make this happen is the condenser coil. This is regularly the aluminum coil the surrounds the air conditioning compressor.
What happens inside this outdoor unit is a very basic state convert of the refrigerant inside the air conditioning unit. The refrigerant that changes from a liquid to a gas inside the indoor coil moves to the outside where the compressor compresses the gas under high pressure. When this happens the gas also becomes very hot. The hot gas then leaves the compressor to start traveling straight through the many feet of tubing in the condenser coil. As the gas cools it changes back to a liquid form going back indoors to start the cycle all over again.

Big problems start when the condenser coil becomes so blocked up with dirt that the hot gas in the condenser coil does not cool enough to convert the hot gas back to a liquid form. If this happens the cooling process does not happen and then air conditioner runs but is not cooling. The compressor starts to get very hot and the ultimate corollary will be the death of a compressor. For these reasons the condenser coil must be kept clean and free of debris at all times when the air conditioner is running. Cleaning the coil is a fairly straightforward process, Here are a few guidelines to corollary when doing this.
To clean the coil a few straightforward tools are needed. A garden hose with a nozzle, wrenches to take off the condenser fan, a garden sprayer for applying the cleaning solution. The first thing is to disconnect the power to the outdoor unit. There should be a disconnect switch of some type near the condenser. Then take off the fan from the condenser unit. regularly this will be the top of the unit. The fan can regularly be laid aside considered without disconnecting the wires to the motor. considered wet down the coil with the garden hose. If you have very high pressure water where you live be meticulous that the water pressure does not bend over the fins on the coil. These are very thin and fragile. If they get bent over the air will not be able to freely flow straight through them. Using the cleaning clarification from the garden sprayer, coat he inside and the outside of the coil. Let the clarification work on the dirt build up before washing it off. If you use a foaming type coil cleaner then let the foam cook the dirt out of the coil. Then use the garden hose to wash the dirt out of the coil. I often work from the inside spraying out straight through the coil. This is the reverse of the usual air flow and it washes the dirt out easier. Rinse the coil with water till it is clean with no more dirt or cleaner coming out. Replace the fan and start the unit back up.
The cleaning clarification for the condenser coil can be any good household cleaner. Many automotive type radiator cleaners will work well. For very dirty condensers it would be good to buy a foaming coil cleaner made specifically for cleaning condenser coils. A local plumbing and heating supply house should stock coil cleaning solutions. Most of these solutions are very strong chemicals. Be sure to wear gloves and eye safety when working with them.
By holding your air conditioning condenser coil clean, you will help to have your air conditioner running at the best efficiency possible. A clean condenser coil is one of the easiest ways to save electric while running your central air conditioning system. A clean coil will allow your compressor to run cooler and help it to last longer. Your condenser coil should be thoroughly cleaned at least once a year. If in you live in very dirty areas like along a dirt road you may need to clean the condenser coil more often. Also do not do things that would clog up the coil. Blowing grass clippings into the condenser coil is one common thing that happens. Keep shrubbery from growing into and colse to the condenser coil. This stops the air flow to the coil. Large flowers planted too close to the coil can do the same thing.
As you can see there are many things that can cause your air conditioner to work harder and cost you more money. By taking a the time to look over things and give it a cleaning you can save a lot of money.
