Rheem AC raka-030jas. not cooling house. New filter, power to entire system, new batteries in thermostat, condenser coils cleaned, no ice on lines, indoor blower is working, outdoor condenser and fan


Its possible that you have too much Freon and also if the fan in the condenser is coming on you need to make sure the compressor is running too. Some of them are quiet. Grab the line and see if you can feel refrigerant running through them to see if the compressor is running.

Charging an air conditioning system


R22 systems should run a 68# to 70# suction pressue. If you look at the suction guage at 68# that is a 40 deg evaporator coil temp.

About the only thing that it could be is a dirty coil,or some one over charge the system, I have seen just a layer of dust cause the compressor to cycle off to its thermal over load. Clean the coil.

I recently purchased a used ac for my rv. it has two and one had gone out. the air coming out of the new one only gets down to 60 degrees while the air out of my old one is 50 degrees. they are both the...


No it means you 50 degree one is working better than perfect. Clean the one that is only getting down to 60 degrees but remember if a unit is dropping the air temp by 20 degrees its working fine. You ck this by cking the air at the intake where the filter is say temp is 80 degrees and then take a reading at a discharge vent where the cold air comes out if its 60 you have a 20 degree drop and that is considered good. If the unit was low on freon the unit will freeze up (ice will form on the inside coil).

My Honeywell AC unit doesn't seem to be working properly. It will not retain a temperature. I set the thermostat to hold a temperature of 70 degrees. Room temp still reads 74 degrees. Something is working,...


The frost on the pipe indicates you have a dirty filter, dirty evaporator coil, Blower not running at the proper speed (to slow) or you are low on refrigerant.

AC not cooling during the day


Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

Air Handler Blower


if you have a meat thermometer, place it in the vent when the air is on, it should be cooling somewhere around 15-18 degrees F lower than what actually temp is, so if its 84 degrees, your unit should blow around 67 degree air out of the vent. if it is not call a tech. your system could be under or over charged.

The thermostat is set at 73... the air conditioner is running and cold air is blowing but the house is currently 82 degrees. I've checked the unit outside and there is no icing. I don't know what to do.


check to see supply air should be around 58F. 20* difference form supply air to return air if 58F my guess unit under sized air filter clean? when was the last time you had the unit tuned up?

Split system blower not blowing any air on heat or ac


You maybe iced up. Turn of AC turn fan on and wait about 45 minutes. If fan is blowing air out of vents chances are you were iced up. Two reason for iceing up are AC coil dirty and low on Freon. You need a service tech to check your Charge on system. If you can get to the coil to clean it grreat. Spray it with water let it set and brush clean with a toilet stool bruch. It will not damage the coil. If it is to stopped up you may have to have a service tech chemicaly clean the coil. Fan motors do go out. ou realy need a service tech to check this Rusty
