Air-con – Cleaning the Fondre Coil

Air Conditioning works by exchanging heat from inside a development to the outside air. To do this some very basic refrigeration principles need to occur. One of the most critical pieces that make this take place is the condenser coil. This is usually the aluminum coil the surrounds the air conditioning compressor.

What occurs inside this outdoor unit is an extremely fundamental state change around the refrigerant inside the air cooling unit. The refrigerant that changes from a liquid to a gas inside the interior coil moves to the external part where compressor compresses the gas under high pressure. Once this happens the fuel also becomes really hot. The hot gas then leaves the compressor to start traveling 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 have the cycle all over again.

Big issues begin when the condenser coil will become so blocked up with dirt that the hot fuel in the condenser coil doesn’t cool enough to load hot gas directlyto a liquid form. If this occurs the cooling process does not happen and then air conditioner runs but isn’t cooling. The compressor begins getting very hot as well as the best result would be the death of a compressor. For these causes the condenser coil must be kept free and clean of debris at all times if the ac is turned on. Cleaning the coil is a relatively easy process, Below are a few guidelines to abide by when doing this.

To clean the coil a few simple tools are necessary. A garden hose with a nozzle, wrenches to remove the condenser fan, a gardening sprayer for using the cleaning solution. The initial thing would be to disconnect the capability to the outside unit. There should be a disconnect switch of some kind around the condenser. Then get rid of the fan from the condenser unit. Normally this would be the top part of the device. The fan may usually be laid aside thoroughly without disconnecting the wires for the motor. Carefully wet down the coil with the garden hose. If you have very high pressure water where you live be careful that the water pressure doesn’t bend over the fins on the coil. These’re really thin and fragile. If they get bent over the air won’t have the ability to freely flow through them. Using the cleaning solution from the backyard garden sprayer, jacket he inside and the external part of the coil. Let the solution work on the dirt build up before cleaning it off. When you make use of 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 inside spraying out through the coil. This’s the reverse of the usual air flow which washes the dirt out easier. Rinse the coil with h20 till it’s clean with no more dirt or perhaps 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 auto type radiator cleaners are going to work well. For incredibly dirty condensers it will be beneficial to buy a foaming coil cleaner created particularly for cleaning condenser coils. A local heating and plumbing supply house should inventory coil cleaning up solutions. Most of these solutions are extremely strong chemicals. Make sure you put on gloves and eye protection when dealing with them.

By keeping your air conditioning condenser coil thoroughly clean, you are going to help to have your air conditioner running at the best efficiency possible. A clean condenser coil is among the most effective ways to save electric while managing your central cooling system. A clean coil will allow your compressor to run cooler and help it to last a bit longer. Your condenser coil must be thoroughly cleaned at least once a year. If in you live in extremely dirty parts like along a dirt road you might need to cleanse 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 occurs. Keep shrubbery from planting into as well as around the condenser coil. This puts a stop to the air flow on the coil. Large flowers planted too close to the coil is able to do the same thing.


As you are able to see there are so many things that can cause your air conditioner to work harder and cost you much more money. By taking a the time period to check out things and give it a cleaning you are able to save a lot of cash.
