Re: Home Air Condition cooling problem
Hello. If your outdoor coils are dirty it's a good chance the indoor coils are dirty also. Clean the indoor coils and flush out the condensate line.
I know it's tempting to feel the air and try to decide if the unit is working properly but, you need to use a thermometer and while the unit is running check the temperature at the return air vent and then check the temperature at the supply vent closest to the unit. Remember to let the thermometer set for about 5 minutes before reading.
You should be looking for about 15 degrees F cooling between the return and supply.
If your coils are clean make sure the outdoor fan is operating properly. The air coming out of the outdoor fan should feel warm, almost hot. If not you may need to check your pressures. Good luck and let me know what you find.

I understand your Frigidaire air conditioner, model# FAS296R2A, is not cooling. I also see that, both the filter and condenser are clean. First, try setting the temperature lower. Secondly, the compressor could have shut off by changing modes. Set to the "COOL" setting and wait about 3 minutes for the compressor to restart. Lastly, check the temperature sensing element, located behind the air filter, to make sure it is not touching a cold coil. If it is, straighten the sensor away from the coil. I hope this is helpful.
What is a condenser? Is a device or unit used to condense vapor into liquid. A condenser is simply one component of an air conditioner. Whether you have an outdoor air conditioner or a window unit air conditioner your air conditioner contains a condenser. Condensers are used in outdoor air conditioning systems as well as heat pump systems. Condensers in an air conditioning unit have very few controls. They will have an on and off switch. Occasionally these air conditioners will also have a brown out option. This option shuts down the compressor when the electrical current is low. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. A condenser is a major component in a air conditioning or heat pump unit. It moves air across the coils to facilitate the transfer of heat. In a heat pump unit the condenser has a few more features. It will have a reverse valve that allows the unit to switch back and forth between air conditioning and heating. Even when the unit is heating, it uses the condenser for defrosting the coils. If the coils become layered with frost it will effect the units effectiveness this is defrosted when the reverse valve switches to air conditioning mode to move the hot gases through the coils melting the built up ice. It will automatically switch back to heating mode once the ice is cleared to once again heat the home. To keep your unit in good operating condition it is vital to keep the area around the condenser clear of all debris as well as keeping the filter clear of dust and dirt. A clean machine makes a happy machine. A happy machine will keep you cool during the summer months and warm during the cold months. It is suggested to change the units filters when they become dirty, depending on your area and conditions near your home this may be as often as once a month or as seldom as every 3 to 6 months. You will have to pay close attention to your units needs to decide the right time to change or clean your unit’s filters. It is very important no matter what type of unit you have to prevent the blockage of the condenser. If the condenser becomes block it can effect the units efficiency or even cause the until to completely fail. For this reason it is one of the most important components of a cooling or heating system. A condenser allows the maximum airflow to the unit. Keeping you condenser in good running condition will not only prolong the life of your heat or cooling system but also provide you with the most efficient heat and cooling system saving you money on heat and cooling.www.victorwod1234.blogspot.com
Water, or in this case - condensation will be created and drip from the cooling coils inside the unit outdoors, if installed correctly. This is a normal condition. Like a cold glass of water sitting on a table or counter on a hot, muggy day; condensation will form.
The amount of condensation forming on the glass - and cooling coils of the A/C - is directly related to the amount of humidity in the air.
Some A/C units have fans that not only force cool air out the front of the unit - but also spray condensate on the condenser coils (the coils that get hot and are visible from the outside) to help cool them down.
If water is dripping indoors - the A/C is tilted inward or drain holes on the bottom edges of the rear (outdoors) are clogged. Adjust the A/C support(s) so that it is tilted back (the bottom rear should be about 1/2" or 10mm lower than the bottom front) and inspect & clear obstructions from the drain holes as needed.
If you have serviced the air conditioner such as cleaning the condenser coil, changing the filter, cleaning the evaporator coil and checking the refrigerant, you have done about all you can do. Most air conditioners can cool up to a 30 degree differential. If its 100 outside most units will be able to maintain approx. 70 degrees. It also depends on how tight the home construction is as well. Find out if you have ample enough insulation in the attic. This always makes a good difference. Also, is there insulation in the walls and how tight are the windows? In the middle of summer all depending what the weather is like, most air cond's are running at their peak. If you have not cleaned the outdoor condenser coil with a hose and a sprayer, you might do so. Turn the power to the unit off first. Also, have the refrigerant checked. Hope this helps.
Check and clean the filter if found to be dirty. It is usually behind a decorative panel below the cold air output grates (when the cold air is on the top front).
The filter is behind the large, rectangular, slotted front panel. The evaporator coil is behind the filter. The fan behind the evaporator pulls the room air through the filter and evaporator coil where it is cooled and dehumidified. It is then discharged through the grates on the top of the front.
Direct the airflow from the unit up and away or left / right to prevent the cool air from being drawn in the front of the unit (this is where the thermostat sensor is located). Use the highest fan speed to help force the air away from the intake, too. Inspect the condenser and evaporator coils (condenser is outside and evaporator is directly behind the filter. Clean if dirty or icing over. Be sure to install a filter if none was present. There are products made specifically for cleaning between the fins of the condenser and evaporator coils. Use them only as directed.
If these suggestions do not work, you may have a problem with the thermostat, refrigerant level, condenser or condenser fan.
You have an air flow problems. Clean the outside condenser coil I use on half baking soda and one half joy soadp squirt this on the coil take a coil brush that you can buy at any hardware store. and go up and down on the coil. then take the water hose and squirt it down to clean the soap and dirt off, It this doesn't solve it you will need to clean the fan blower motor the squrrel cage but don't get the motor wet. Next you will need to clean the evaporator coil just take the coil brush and go up and down to clean. This should solve your problem, What kind of readings did you get on the low side and high side. You should have a 40 degree drop across the evapartor. And the high side should be the out side temp and 30 degrees. If you have any questions you can email me at crislsparks@gmail .com. What kind of freon does it the unit take. It will tell you on the nameplate on the outside unit.
Check the outdoor unit to see if it is discharging hot air out of the top ofd the unit, check the insulated suction line to make sure it is cold or sweating. Try to listen to the outdoor fan and the compressor to make sure they are both operating
First check and clean the filters, and the evaporator coil. (thats the "inside" coil that has the indoor air sucked through it, cooling it and then pushing it out the vents.
If the filter is clogged or the coils are dirty, it will not cool properly and potentially freeze up.
Also check the condensor (outdoor) coil, if it is dirty/clogged, it will run hot and not cool properly.
If all coils and filters are clean, and the fan motors are running and in good condition and it is still not cooling then you are likely low on refridgerant. (handling/purchasing refridgerant other than R134A requres a CFC certification by law)
Possible causes are dirty filters, dirty condenser coil, dirty evaporator coil, or low referigerant charge. Any one of the conditions will affect heat transfer.
Check the filters in your indoor unit, If they seem to be clean and replaced on a regular basis, your evaporator coil is probably in good shape. Unfortunatley on some Weather King models even checking the evaporator coil is not possible due to the extensive amount of referigerent lines that block access to the coil without some major work including evacuating the refrigerant.
The most likely cause is a dirty outdoor condenser coil. On weather king models you will have to remove the casing that surrounds the coil because is is built in such a way that the condenser coil cannot be properly cleaned with the casing in place. Once it is removed make sure breaker is switched off and clean the coil with a water hose.
If your outdoor coil is not dirty then it is a refrigerent problem.
Check the filters inside and the evap coil to make sure it isnt filthy. The evap coil can be cleaned with a credit card if its wet. The large line outside should sweat all the way to the compressor if its got enough freon. Will freeze when its cool outside or not sweat at all if its low. Good luck with it.
