If your AC is blowing hot air, it can be a major inconvenience, especially on a hot day. There are a few common reasons why this can happen, and most of them are relatively easy to fix.
1. Dirty or Clogged Air Filter: One of the most common reasons why ACs blow hot air is a dirty or clogged air filter. Air filters trap dust, dirt, and other allergens from the air, but over time, they can become clogged and restrict airflow. This can cause the AC to work harder than it needs to and prevent the coils from cooling correctly.
2. Low Refrigerant: Refrigerant is the gas that circulates through the AC system to absorb heat from the air. If the AC is low on refrigerant, it won't be able to cool the air properly.
There are a few reasons why an AC might be low on refrigerant, such as a leak or a problem with the compressor. If you suspect your AC is low on refrigerant, it's essential to call a qualified HVAC technician to diagnose and fix the problem.
3. Dirty Condenser Coils: The condenser coils are located outside the AC unit and are responsible for releasing heat into the atmosphere. If the condenser coils are dirty, it can prevent them from releasing heat properly, and this can cause the AC to blow hot air. To clean the condenser coils, you can use a garden hose and a brush to spray them. You can also use a commercial coil cleaner to remove stubborn dirt or grime.
4. Frozen Evaporator Coils:The evaporator coils are located inside the AC unit and are responsible for absorbing heat from the air. If the evaporator coils freeze, it can prevent the AC from cooling the air properly.
There are a few reasons why the evaporator coils might freeze, such as a dirty air filter, low refrigerant levels, or a problem with the compressor. If you suspect your evaporator coils are frozen, you must call a qualified HVAC technician to diagnose and fix the problem.
5. Malfunctioning Compressor: The compressor is the heart of the AC system and is responsible for circulating refrigerant through the system. If the compressor malfunctions, it can prevent the AC from cooling the air properly.
There are a few reasons why the compressor might malfunction, such as a leak, a problem with the motor, or a lack of lubrication. If you suspect your compressor is malfunctioning, it's essential to call a qualified HVAC technician to diagnose and fix the problem.
If you have tried all of the above and your AC is still blowing hot air, it's time to call in qualified HVAC technician. A more serious problem with the AC system may need to be diagnosed and fixed by a professional.
Here are a few tips for keeping your AC running smoothly and preventing it from blowing hot air:
1. Change the air filter every month or two.
2. Clean the condenser coils once a year.
3. Have your AC system inspected and serviced by a qualified HVAC technician once a year.
By following these tips, you can help ensure that your AC will keep you cool and comfortable for years.
1. Check the thermostat setting to ensure the AC is set to cool mode.
2. Check the air filter to ensure it is clean and not clogged.
3. Check the condenser coils to make sure that they are clean and free of debris.
4. Clean the condenser coils with a garden hose and a brush if they are dirty. You can also use a commercial coil cleaner to remove any stubborn dirt or grime.
5. If the condenser coils are clean and the air filter is clean, but the AC is still blowing hot air, there may be a more severe problem with the AC system. In this case, it's essential to call a qualified HVAC technician to diagnose and fix the problem.
If your AC is blowing hot air, don't panic. There are a few common reasons why this can happen, and most of them are relatively easy to fix.
