Why does my ac not blow cold air?

The indoor unit only blows warm air. the out side unit sounds like the compressor kicks on , but i noticed that the outside unit condensers don't get warm at all.

The air blowing out of the condenser should be warmer than the ambient temperature , provided the compressor is running. If compressor running but no warm air, you are likely out of refrigerant. Check the larger of the 2 copper lines at condenser, it should be cool and sweating like a glass of ice water. I've not, likely low refrigerant.

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds After you turn it back on the system should reset. If you need any other assistance check us out online at Boca AC Service we are always happy to lend a helping hand

You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze

SOURCE: the unit only blows warm air. it just stopped

The compressor is not starting either because:
1. The compressor has gone bad
2. The system is low or out of refridgerant. There may be a slow leak, when there is no refridgerant in the system the compressor will not start.

Fix:
Re-charge the system with appropriate refridgerant, if the system has a charge already or holds a charge when you charge it then the compressor should start.
If not the compressor could be bad, sometimes you can get a hard start kit instead of replacing compressor. If the system does not hold a charge then you have to find and repair the leak before anything else...

Good luck. Please give good rating, it meens a lot to me....Feel free to contact me again...

SOURCE: ac fan on, blowing air, but not cold

Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

SOURCE: AC unit outside blowing out cold air, vents

If you have a heat pump probably there's a wrong connectionin the thermostat, but if is not a heat pump ,the compresor is not working or the unit leaked all the refrigerant.

Testimonial: "thank you, we have had a problem in the past with refrigerant leaking, was supposed to be fixed"

AC blows warm air. 07 GMC Envoy 6 cyl. 4wd

You probably replace the wrong switch. I believe the high pressure switch is mounted in the back of the compressor. Pull the plug and jump it. If it works, replace the switch. I don't recommend you leave the jumper in the plug. If it the A/C pressure is to high, you could blow lines and such. Costing you a lot of money.

Blows cold when first started and then blowes warm

I would replace the AC compressor cycling switch it may be sticking have seen it a number of times. The switch is located in the receiver dryer on the passenger side of the engine compartment. See picture below.

If this isn't the problem the AC compressor relay may also cause this, flip a coin.

A/c and heater problem A/C will sometimes blow cold air for about 20 seconds then start blowing warm air. Then when using the heater it will blow warm air for about 20 seconds or so then start blowing cool...

sounds like you may have developed a leak in the system, when the pressure in the system is low it will cause the compressor to cycle off and on. Have you tried to charge the system? P.S. Dont know if you are aware but hte compressor kicks on when the heat is on as well as he AC.I hope this helps and good luck !!

Compressor will not stay on.

very good possibility that it is low on freon. If indoor unit is blowing ambient air, not cooling is happening. If this is the case and you are sure the compressor is running and then shutting off, the compressor could be overheating and the internal overload is taking out the compressor. If outdoor fan runs and compressor runs, probably cause. If capacitor is bad, unit would most likely not run that long. While unit is running, feel the large line at the condensing unit. If it is cold, and stays cold, could be something else going on. If stays warm, most likely low on freon.

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.
