Air conditioner – Cleaning the Condenser Coil

No Comments Uncategorized

Air Conditioning works by exchanging high temperature from inside a construction to the outside air. To do this some very basic refrigeration principles need to occur. Among the most crucial pieces that make this take place is the condenser coil. This’s usually the aluminum coil the surrounds the air conditioning compressor.


What takes place inside this outdoor device is a really fundamental state change around the refrigerant inside the air cooling unit. The refrigerant which changes from a liquid to a gasoline inside the inside coil moves to the outside where the compressor compresses the fuel under high pressure. When this happens the fuel also becomes really hot. The hot gas then leaves the compressor to begin traveling through the many feet of tubing in the condenser coil. As the gasoline cools it changes back to a liquid form going back inside to start the cycle all over again.

Big problems begin when the condenser coil will become so blocked up with soil that the warm gas in the condenser coil doesn’t cool enough to change the hot gas directlyto a liquid form. If this takes place the cooling process does not happen and then air conditioner runs but is not cooling. The compressor begins to get very hot and the ultimate result will be the passing of a compressor. For these reasons the condenser coil must be kept free and clean of debris at all times when the ac is running. Cleaning the coil is a fairly simple process, Here are a few guidelines to abide by when doing this.

to be able to clean the coil simple tools are needed. A backyard garden hose with a nozzle, wrenches to remove the condenser fan, a garden sprayer for applying the cleaning solution. The first thing is to disconnect the capability to the outside unit. There must be a disconnect switch of some sort close to the condenser. Then remove the fan from the condenser unit. Usually this would be the top part of the unit. The fan can typically be laid aside thoroughly without disconnecting the cables to the motor. Carefully wet down the coil with the garden hose. If you’ve very high pressure water where you live be mindful that the water pressure doesn’t twist over the fins on the coil. These are very thin and fragile. If they receive bent over the air won’t have the means to freely flow through them. Using the cleaning solution from the garden sprayer, coat he inside and the outside of the coil. Let the solution work on the dirt increase before cleaning it off. If you use a foaming type coil cleaner then allow the foam cook the dirt out of the coil. Then make use of the garden hose to clean the dirt from the coil. I usually work from the insides spraying out throughout the coil. This is the reverse of the typical air flow which washes the debris out easier. Rinse the coil with h20 till it’s thoroughly clean with no more dirt or cleaner coming out. Replace the fan and start the product back up.

The cleansing solution for the condenser coil could be any good household cleaner. Many automotive type radiator cleaners are going to work well. For incredibly dirty condensers it will be beneficial to purchase a foaming coil cleaner made especially for cleaning condenser coils. A local plumbing and heating supply house should inventory coil cleaning solutions. Most of these solutions are very strong chemicals. See to it that you put on gloves and eye protection when dealing with them.

By keeping your air conditioning condenser coil thoroughly clean, you will help to have your air conditioning running at the very best efficiency possible. A fresh condenser coil is one of the easiest ways to economize electric while operating your central cooling system. A clean coil is going to allow your compressor to run less hot and help it to last a bit longer. Your condenser coil must be thoroughly cleaned at least once a year. If in you reside in extremely dirty areas like along a dirt road you might need to purify the condenser coil much more often. Also do not do things that would clog up the coil. Blowing lawn clippings into the condenser coil is one common thing that happens. Keep shrubbery from gardening into and around the condenser coil. This prevents the air flow for the coil. Large flowers planted very close to the coil is able to do exactly the same thing.

As you are able to see there are so many things that can cause your ac to work harder and set you back much more money. By taking a the time to look over things as well as give it a cleaning you can save a lot of money.
