This normally deals with the AC in the ar needing to be charged again. There is a unit in the AC that they fill with a product that needs to be charged from time to time. If this is not the issued it is a problem with the heater and the AC unit and the problem could be in a hose in the car. No matter what it will need to be taken into a shop to have it looked at.
One obvious reason could be that the AC gas is finished or out of coolant or refrigerant. Another reason could be the compressor is faulty. Any form leakage within the tube may cause your AC to blow hot air. Dirty evaporator from air filter could. The best test is to take for check so that to properly diagnose the problem.
The AC might be blowing hot air because it is cold outside and the machine is running very hot.
Some possible reasons include:
1) The AC is not working properly or there is jolt of electricity being produced when the car is started.
2) The AC is not being used full power or for it's lifespan which could cause temperatures on the AC unit to increase.
3) The AC is overloading and might be overloading of some kind which could cause the car AC to be too hot.

There are several possible reasons why your car's AC may be blowing hot air instead of cool air. Here are a few things to check:
Low refrigerant levels: The most common reason for an AC to blow hot air is low refrigerant levels. This can be caused by leaks in the system or by normal wear and tear over time.
Compressor issues: If the AC compressor is not working properly, it may not be able to compress the refrigerant and circulate it through the system. This can cause the AC to blow hot air.
Clogged or dirty condenser: The condenser is responsible for removing heat from the refrigerant. If it becomes clogged with dirt or debris, it can't do its job properly and may cause the AC to blow hot air.
Faulty cooling fans: The cooling fans help circulate air over the condenser to keep it cool. If they're not working properly, the condenser can overheat, causing the AC to blow hot air.
Electrical problems: There may be an issue with the electrical system, such as a blown fuse or faulty wiring, that is preventing the AC from working properly.
Failed temperature sensors: Temperature sensors measure the temperature inside and outside the car and adjust the AC output accordingly. If these sensors fail, the AC may not know when to blow cool air.
If you're not comfortable diagnosing and fixing these issues yourself, it's best to take your car to a qualified mechanic for inspection and repair
