Try cleaning your air conditioner's filter and the coils to see if improving the airflow fixes the problem. If there is ice buildup, you'll need to run the unit with just the fan in order to melt it off. If that doesn't get the unit blowing cold air again, it could be refrigerant levels are low (see below).

If it is in the air conditioning mode, check for ice around the evaporator coil and on the refrigerant lines at the indoor unit.

Higher than normal air pressure is usually a consequence of two situations. One, your AC system might be facing limited or no airflow through the condenser. This, in turn, might be a consequence of bad condenser fan motor. If you have debris near the fan blocking the flow, you will face the same issue.

No warm air delivery at all. If you turn your central heating system on and set it to the desired temperature but it doesn't deliver any air, you'll have to attempt to isolate the problem. It might be a tripped or bad breaker, an issue with the electrical wiring, or, it could be the unit itself no longer works.

The most common cause of window air conditioners not blowing cold air is a lack of adequate air flow. ... If the air filter is dirty or clogged, there may be little or no air flow over the evaporator coils, which may cause them to become too cold and frost or ice can form on them, restricting the air flow even more.

Your refrigerant is low. One of the most common causes of an AC system blowing warm air is a lack of refrigerant. ... Regular shutoffs when the room temperature is correct give ice on your evaporator coil a chance to melt, so low refrigerant can lead to a cycle of warm air and icing on your evaporator coil.

The AC unit won't turn on Usually when the outdoor unit doesn't turn on, it is because the circuit breaker has been tripped. When this happens, you can easily reset it after locating the circuit breaker panel. If you find that the AC unit still does not work, the next probable cause is the thermostat.
