Having problems with your Air Conditioners ?

Air Conditioning I have a ruud system with the air conditioner outside and the air handler upstairs in the attic. My systems appears to be running, and I can feel cold air at the vents, but I can barely feel it. Like there is no flow. The fan outside is running and the unit in the attic is running. I have no clue what the problem is. The large coil coming from the heat pump outside is cold and has condensation on it. It also seems to have a little ice. It has been extremely hot here in Ge


Answers :

Open the access panel on the air handler in the attic and take a look at the evaporator coil. If you have no airflow, and you just changed the air filter, then you probably have a buildup of airborne crud on the coil that's blocking airflow. \015\012\015\012If you do have a layer of buildup blocking airflow through the coil in the air handler, just take a $5 fin comb and scrape all the crud off the coil fins. This can make a dramatic difference. \015\012\015\012Hope this helps! ;)

No heat We had the mini split installed and have not needed the air conditioner yet. But now that I want the heat on, I can't get any. The indoor unit lights up and the fan comes on but only blows cold air. I have checked everything I dare to, and noticed that the outside unit doesn't seem to be running. I am reluctant to call the guy who installed it because he was not a happy guy to do it in the first place. But he was the builders choice. Any suggestions of things to check into myself?

I have a Inter therm Model# FEHB015HA central heat & air unit that I had problems with in the summer as the out side unit would not come on but the blower would kick on but nothing on the outside unit(No cold air).Ok I fixed that as it was the the transformer that switched it down to 24 volt to go to the outside.Now I have noticed that when the heat is on it will not kick the outside unit on?It has been very cold here in Georgia but right now as I type it is 50 degree's and the outside unit is s


Hi, if this is not a gas fired split system, it is a heat-pump with aux heat strips. The outdoor unit must be on to warm you're home by way of the reversing valve. The strips in the indoor unit are for emergency and auxiliary heat only. ... Air Conditioners

Wall A/C only SPORADICALLY blowing cold air. Turn it off and back on, you can feel it's cold, but only if you're 5 inches from it. After a couple of minutes, fan is only blowing warm air again. Vacuumed front of A/C, still doing the same thing. Filter is clean. It is over 100 degrees outside with very low humidity the last few days.(Los Angeles) ; since it's a wall a/c, of course 1/2 of it is outside in the heat. As I noted, if you put your hand right up against the front, you can feel cool air

I recently had a new outdoor unit installed on my central heat and air conditioning sytem. I have had the installer out 3 times and the system still does not operate correctly. Sometimes when it cycles (every other time or every third time) the unit does not blow cold air. Sometimes the unit comes on not blowing cold air and the compressor fan is running but not the compressor. Sometimes after 15 minutes of this the compressor will come on. What is the problem.


It sounds like the compressor needs starting components installed on it. All a/c units have a run capacitor for the compressor and another one for the condenser fan motor. These motors use these capacitors all the time when the motor is running. H ... Air Conditioners

I have an AR32-1 with an emergency heat switch on the thermostat. The heat pump runs and runs and runs and blows cold air when it's freezing outside. If I turn on the 'emergency heat', nothing happens. We do have three 220V breakers in the panel box. One is labeled 'heat pump', the other two are labeled 'furnace'. What could be wrong that the 'emergency heat' does not work?

Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from copper pipe. Minute later sound stopped & air was suddenly hot. As if AC was turned on fan not cold. Went outside & neither fan nor motor was running. Turned fan manually. Ran for about a minute then stopped. Outside unit was making what could best be described as a buzzing sound.

After a cooling cycle, when the thermostat call for more cooling, it take up to 5 minutes after the air handler starts for the compressor motor to restart. The top fan operates on the outside unit, but since the house is not circulating cold air, only the room tep air the house heats up about 3 degrees before the compressor comes back on and cool air begins to come from the ducts. Yes. I know there is a safety feature to protect the compressor, but can the cycle be shortened?

I have a Toshiba Heat pump. 220-240V 50HZ 40 watts. I have lost the manual and do not know how to get it to give me hot air. I put the temp at 22deg but seem to just get cold air blowing in on me all the time. Surely when it is 5deg outside I should be able to get hot air coming form the stupid machine. However said heat pumps were good obviously hasn't got one of these!!!

I live in Florida, my a/c system, I believe it is a Rheem, has been heating the house fine all of this winter no problem.

Airflow We have a new ducted PEH-MYB reverse cycleairconditioner. We set the temperature at 20 degress for heating. Once it reaches it it then blows out cold air. We have had someone come 4 times already to fix various problems. It is not nice to sit near a duct and feel cold air.
