Where is reset button on my outside a/c unit


If you are talking about the condensor that sits outside,there are high pressure and low pressure devices that have a red button on the top of them, turn off power and push the button. They are sometines located inside the unit under the fan. Generally there are none and the unit has internal overloads that kick it out. they reset themselves after the compressor cools down. If it resets after cooling down then ask yourself why it got hot. use a hose and clean the coils around the unit.sometimes helps. make sure fan is running on the condensor outside. It should come on first.

Air Conditioning - Cleaning the Condenser Coil


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} Air Conditioning works by exchanging heat from inside a building to the outside air. To do this some very basic refrigeration principles need to take place. One of the most critical pieces that make this happen is the condenser coil. This is usually the aluminum coil the surrounds the air conditioning compressor.
What happens inside this outdoor unit is a very basic state change 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 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 change 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 result 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 simple process, Here are a few guidelines to follow when doing this.
To clean the coil a few simple tools are needed. A 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 power to the outdoor unit. There should be a disconnect switch of some type near the condenser. Then remove the fan from the condenser unit. Usually this will be the top of the unit. The fan can usually be laid aside carefully without disconnecting the wires to 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 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 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 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 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 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 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 protection when working with them.
By keeping 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 around 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.

Replaced a starter capicator, now it just bloweswarm air


On hot day your unit may not cool enough. Make sure that outside unit is clean, filter inside should be clean. If all above is good your unit may be low on Freon.

My home air conditioning unit comes on with the thermostat and blows cold air when the outside temp is 80 or below/ When the outside temp is hot, above 90 degrees, the unit will not turn on. Any...


Make sure the coils on the outside unit are clean as can be, if any dirt or anything else is blocking the air flow on the coils, take a water hose with a medium stream and work your way from top to bottom, being carefully not to damage the aluminum fins. You can also be over charged on refrigerant which will have the same effect as dirty coils and cause the pressures to get so high, the compressor over works, over heats, and shuts off on thermal overload. It is still possible that it will blow cool air when the temp outside isn't that high, simply because the pressures are further down on the system. I would start there at least, it's easier when your there in person sometimes. Hope this helps anyways, if not, write another question but be sure to explain which components are working, inside and outside, and if the filters have been changed, and if the coils have been cleaned. It just helps to narrow it down. Again, hope this helps and good luck!

Why would cool air be blowing out of my central ac unit condensor that sits outside? The other unit I have next to it blows out warm air and responds well to thermostat changes. The unit blowing cool air...


It probably has a low refrigerant charge. The air coming out of the outside unit should be warmer than the outdoor temperature when in the cooling mode and if it's a heat pump it should be colder than the outdoor temperature in the the heating mode. Check the big line going to the unit, it should be somewhere around the 40 F range and the small line should be hot.

PROBLEM WITH MY AIR CONDITIONER


Is the outside unit running? if so can you feel warmer than outside air blowing from outside fan? If not your system may have a leak and pressures low. You can also check the piping to and from the unit larger one should be cold small one should be warm

Uotside unit blowing cool air but hot on the inside


It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.

Hot air coming out of back


portable air conditioners mainly have two hoses one hose is exhaust thats the one that is blowing hot air. the one pulling is return.. the hot air blowing out should be exhausted to the outside. the blowing air needs a hose and to be laid out a window the back should have model and serial maybe product number. the two holes are either 4 inch or three inch and most portable units other than hand me downs come with a window frame that allows the hot exchanged air to go outside and cooler air to be used for heat exchange.

Blowing hot air


Water in the pan is normal, this is the humidity removed from your space. Pan must be emptied regularly. If the unit shuts down after 15 minutes, you may have a blocked hot air duct. Make sure it is flowing freely. This includes makeup air from outside the room to replace that blown outside by the AC.
