Top 5 reasons for aircon blowing hot air

A dirty filter will cause a restriction in airflow, which will cause the evaporator coil to freeze over, causing the unit to blow warm or hot air. Routine maintenance service on your system should keep this from happening.
If you have a faulty fan motor then this could also cause warm or hot air to be blown from the unit. The fan motor moves the air from outside through the condenser coils and into your home. If the fan motor is faulty then not only will you get warm/hot air but also restricted airflow through your system too causing.
When a compressor breaks down, it can lead to many problems including leaks in the refrigerant lines and hot air being blown out of the vents instead of cool air. If you suspect that your compressor is broken, call for professional help immediately as this can cause further problems if left unattended to!
The refrigerant in your air conditioning system helps cool the air inside your home. If the unit is low on refrigerant, it will not blow cold air. Most of the time this means there is a leak somewhere in the system, but it can also mean that the refrigerant was undercharged when it was installed. You will probably need an HVAC technician to help you resolve this issue.
