Your air compressor is dead or the refrigerant has leaked out. Wait!!! Don't give up yet. This very same situation happened to me. I had air blowing(not cold at all) but the outside A/C compressor was not running. Check your inside unit which is either in a closet or in your attic. There is a water pan underneath it. If it is full of water, it has activated a floating shut-off switch that is wired directly to your outside Compressor. You must remove the water. the best way is with a large wet-dry vac. Then make sure the drainage pipe is properly connected and is not clogged. You can probably fix that by sucking out the drain pipe with your vacuum. Once the water is gone, your floating shut-off switch will re- activate your Air Conditioner. Kind of like the floating ball in your toilet. You may sweat a lot, but you will save yourself a service call and some big bucks. Good Luck!!!

∙ 14y agowhy does ac blow warm air? why does ac blow warm air?
Because the air handler and ductwork are full of warm air from not running and cooling is not instantaneous upon start up. It takes 2 or 3 minutes of run time for the unit to begin cooling.
Check upstairs heating unit.
There are a few reasons why a central air unit is not blowing cold air. The coils may be dirty, the unit may need freon, or the thermostat could be broken.
it could be the heater core and ac housing unit that allows hot air to be mixed with the cold air or it could just cancel out the cold due to the motion of the car
Central Air Conditioners are installed into your house to provide cooling air in every room using a duct system. They are very refreshing on a hot day.
check your thermocoupler. It will not let the gas flow if it is faulty. Easy fix too.
ruud furnace only blows cold air, no heat
a/c blows warm air when idles cold when running
Your climate control in your 1998 Ford E250 Cargo Van blows cold air when in heat position and sometimes it blows warm air when in the cold position?
Check the filter. If in doubt filter is working , remove filter and verify A/C continues to mal-function.
If the air conditioning pump in the 1993 Chevy Z24 blows perfectly, but won't get cold, it is possible that the Freon needs to be recharged in the air conditioning unit. This can usually be done for about $40 by the consumer.
