Central Air Conditioning not blowing out air?

Question

The unit outside is running and has ice on it... (its not cold outside). It won't blow air out in the house. We have the thermostat turned on 65 and it still won't kick on... what do we do?

Answer 1

Before you go to great expense check the vents and air filter. It could be as simple as that. Probably not, but I would change the filters and make sure the vents are clear before anything.

Answer 2

You shouldn't have ice anywhere. Turn the unit off and let it thaw and dry. Is this by chance a "heat pump" ? If so, it sounds like it is in heat mode.
Anyway, your inside blower should be running. If not, there could be a broken belt, or bad motor. If running and no air, there could be air leaking out, or your evaporator coil (in the furnace) could be frozen over. Improper refrigerant level or control could cause the problem. A simple belt you can repair yourself. Make sure you turn off power to the unit before you attempt to work on it.
You could have clogged filters or even the coil. Other than that, get a professional to work on it. Air conditioners have high voltages, moving parts, and high pressure coolant, all of which can be dangerous!

Answer 3

We just had the same problem. Seems my landlord was doing the cheap central air installation and used tape to seal the tubing vents that brings the cool air into the house. Check all of your duct work, there may be a small leak that makes a BIG difference. Ours was just a little tape around a tube that let loose. Mine ran for 2 days straight before figuring it out. Good luck!

Answer 4

Sounds like the compressor is working overtime, but having ice is not good. It could be blocking the tube inside that is suppose to be blowing the air, shut it down for the day and let the ice melt. You might have to take the tube off and drain the water inside.

Answer 5

once you're saying condensor, do you propose the exterior unit?? in case you're checking the evaporator on the in the closet or attic then it somewhat is doing what it became into designed to do?? now if the exterior unit is blowing cool air then curiously the unit could desire to be froze by potential of low refrig. or the compressor isn't working. if the compressor isnt working then its the two the starter windings are undesirable or the commencing up capacitor is shot??? is likewise that this a warmth pump?? if so determine you have the t-stat set to relax and not warmth. in the warmth mode a warmth pumps exterior unit somewhat turns into the evaporator and the indoor unit turns into the condensor by potential of potential of a three-way valve reversing the flow of freon. if the probelm is electric my suggestion is to pay somebody to troubleshoot! engaged on 240volts is risky and stupid for a beginner!!

Answer 6

There are only three possibilites here and you can determine which one it is here goes.

Check the air filter, if its clogged, replace. Problem solved,after deicing of course

Secondly is the motor on your furnace running to spread the air throughout your house, if not you need a repairman.

Lastly if you find that the above two are |OK, you are in need of freon and need a repairman.

Answer 7

Your unit sounds like it's frozen over. You need to turn it off until it thaws and, if the problem persists, chances are you have a leak and it isn't regulating its own temperature properly, in which case you'll need to call a repairman.

Answer 8

ice on the lines can be a sign of low freon!!!! shut your system off for 24hrs or until the ice thaws!!!!!! then have the freon levels checked, chances are thats your problem... if this continues you probably have a leak in your line! shooting the line with liquid nitrogen will help locate the leak
