If the repair person recommends a refrigerant adjustment, ask for proof of the freon leak. Here are some possible causes and things you can do:
Low refrigerant level: This can cause your air conditioner to blow hot air due to insufficient cooling agent circulating in the system. Low refrigerant levels can be caused by leaks in the refrigerant line or a faulty expansion valve. If the refrigerant level is low, the air conditioner will need to be recharged.
Maintenance issues: A lack of maintenance can also cause your air conditioner to blow hot air. For example, dirt and debris on the evaporator coil can block airflow and reduce cooling efficiency. Regularly cleaning and maintaining the air conditioner, including changing the air filter, can help prevent this problem.
Thermostat issues: A faulty thermostat can also cause your air conditioner to blow hot air. If the thermostat is set incorrectly or is not working properly, it won't be able to signal the air conditioner to turn on and cool the air. Check the thermostat settings and ensure it's set to the correct temperature.
If you have tried these troubleshooting steps and your air conditioner is still blowing hot air, it's best to call a qualified technician for further diagnosis and repair. They will be able to identify the exact problem and perform the necessary repairs.
