Air conditioner – Cleaning the Fondre Coil
Air Conditioning works by exchanging heat from inside a building to the outside air. To do this some very basic refrigeration principles have to occur. One of the most vital pieces that make this happen will be the condenser coil. This’s usually the light weight aluminum coil the surrounds the air conditioning compressor.
What occurs inside this outdoor device is a really basic state change around the refrigerant inside the air conditioning unit. The refrigerant which changes from a fluid to a gasoline inside the indoor coil moves to the external part in which the compressor compresses the gas under high pressure. When this happens the fuel also becomes really hot. The hot gas then foliage the compressor to start traveling through many legs of tubing in the condenser coil. As the gas cools it changes directlyto a liquid form going back inside to start the cycle all over again.
Big issues begin if the condenser coil gets so blocked up with dirt that the warm gasoline in the condenser coil does not cool enough to load hot gas to a liquid form. If this occurs the cooling process does not happen then air conditioner runs but isn’t cooling. The compressor happens to get very warm and also the best result will be the death of a compressor. For these causes the condenser coil must be kept clean and free of debris at all times when the ac is turned on. Cleaning the coil is a fairly simple process, Below are a few guidelines to follow when doing this.
In order to clean the coil simple tools are necessary. A garden hose with a nozzle, wrenches to remove the condenser fan, a garden sprayer for using the cleaning solution. The first thing is usually to disconnect the power to the outdoor unit. There should be a disconnect switch of some sort around the condenser. Then get rid of the fan from the condenser unit. Usually this would be the top of the unit. The fan can generally be laid aside thoroughly without disconnecting the cables 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 does not fold over the fins on the coil. These are really thin and fragile. In case they get bent over the air won’t have the means to readily flow through them. Using the cleansing solution from the garden sprayer, jacket he inside and the exterior of the coil. Let the solution work on the dirt build up before scrubbing it off. When you use a foaming style coil cleaner then let the foam cook the dirt from the coil. Then use the garden hose to cleanse the dirt out of the coil. I often work from the interior spraying out throughout the coil. This is the reverse of the usual air flow and it washes the debris out easier. Rinse the coil with h20 till it’s clean with no more dirt or even cleaner coming out. Replace the fan and begin the device back up.
The cleaning solution 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 beneficial to buy a foaming coil cleaner created specifically for cleaning condenser coils. A local heating and plumbing supply house should inventory coil cleaning up solutions. Most of these solutions are incredibly strong chemicals. Make sure you put on gloves and eye protection when working with them.
By keeping your air conditioning condenser coil thoroughly clean, you will help to have your air conditioning running at the most beneficial efficiency possible. A fresh condenser coil is one of the easiest ways to save electric while running your central cooling system. A clean coil will allow your compressor to run cooler and support it to last longer. Your condenser coil should be thoroughly cleaned a minimum of once a year. If in you reside in very contaminated parts like along a dirt road you may need to clean the condenser coil a lot more often. Also don’t do things that would clog the coil. Blowing lawn clippings into the condenser coil is but one common thing that takes place. Keep shrubbery from planting into and around the condenser coil. This prevents the air flow on the coil. Large flowers planted very close to the coil can do exactly the same thing.
As you can see there are numerous things which can result in your ac to work harder and set you back much more money. By taking a the time period to check out items as well as give it a cleaning you can save a lot of money.
