What could be wrong when my AC is running but no cool air is coming out?

Answer by  jsflw2010 (459)

Read the product owner's manual for troubleshooting. The most likely issue, the freon needs recharged and there could be a leak. Contact a service technician.

The most likely cause of this is that it needs to be charged. Air conditioners only work when they have freon in them to do the work. An air conditioner that doesn't cool probably doesn't have freon in it. If it has no freon in it then you might have a leak. Its best to get help from a professional.

Your AC could be low on freon, the liquid component inside of the AC unit that makes the air cold. It also may be that there is a leak in the freon compartment. You should also check to see that the filter is clean, as it can affect the efficiency of the AC.

There could be several things wrong. There could be a leak so that there is no more refrigerant or coolant, which means that the air is still coming into the unit, but not actually getting cooled down. You should have an air conditioning specialist check it out.

The air condition has many functions. If it is not working, then you may need a new compressor. But chances are, you may just need a charge of Freon.

When your AC is running and no cool air is coming out you may have a leak in your AC system. There is also a possibility of the compressor clutch being bad and the compressor not even pumping the refrigerant.

The most common reason for your problem is lack of Freon. You need to get the car to a mechanic to check it out. It's worth the cost; running the A/C without Freon can damage it. Could also be a sensor or compressor problem, but not likely.

The simplest possibility is that your air conditioner is out of freon, or whatever cooling agent it uses. You could also have broken or damaged coils. Only an air conditioning repairman can tell. This sort of repair is probably not going to be very expensive.

Well, it sounds like the fan has burned up. It seems like it is overworked. You have to replace the part.

Answer by  JRossi17 (788)

If its a home A/C it could either be on fan or if its really old it could have run out of freon. If its a car then the system needs to be recharged.
