In this blog post, we'll give you some tips on how to troubleshoot your AC and get it back up and running. Stay cool!

 

Air Conditioner not blowing cold air but running or ac cooler not working

 

If your air conditioner isn't working properly, don't sweat it! Follow these tips and you'll be up and running in no time. Or if you want to buy a new one, click here.

 

Check AC air filter

The air filter in your AC unit needs to be clean in order for the unit to function properly. A clogged or dirty air filter will restrict air flow, which can cause the unit to overheat and shut down. To clean or replace your air filter:

1. Turn off the thermostat of your AC unit.

2. Locate the air filter. It will be either in the return air duct or in the blower compartment.

3. Inspect the air filter and if it is dirty, clean it with soap and water or replace it with a new one.

4. Once the air filter is clean or replaced, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Check AC evaporator coil

The evaporator coil is responsible for absorbing heat from the indoor air. If this coil becomes frozen, it can restrict air flow and cause the AC unit to shut down. To thaw a frozen evaporator coil:

1. Turn off the thermostat of your AC unit.

2. Locate the evaporator coil. It will be in the blower compartment of the AC unit.

3. Inspect the evaporator coil for ice or frost build-up.

4. If there is ice or frost build-up, use a hair dryer to thaw the coil. Do not use an open flame!

5. Once the coil is thawed, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Check AC condenser coil

The condenser coil is responsible for releasing heat from the refrigerant. If this coil becomes dirty, it can reduce the AC unit's ability to release heat, causing the unit to overheat and shut down. To clean the condenser coil:

1. Turn off the thermostat of your AC unit.

2. Locate the condenser coil. It will be in the outdoor unit of the AC system.

3. Inspect the condenser coil for dirt and debris build-up.

4. If there is dirt and debris build-up, use a garden hose to spray off the coil. Be sure to disconnect any electrical power to the outdoor unit before doing this!

5. Once the coil is clean, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Check AC refrigerant levels

The refrigerant in your AC unit is responsible for absorbing heat from the indoor air. If the level of refrigerant is low, it can cause the AC unit to overheat and shut down. To check the level of refrigerant:

1. Turn off the thermostat of your AC unit.

2. Locate the low pressure service port. It will be located on either the indoor or outdoor unit of the AC system.

3. Use a refrigerant pressure gauge to check the pressure of the refrigerant. The pressure should be within the manufacturer's specified range.

4. If the pressure is too low, you will need to add more refrigerant. This should be done by a professional AC technician.

5. Once the proper level of refrigerant is restored, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Check AC for leaks

A leak in the refrigerant line can cause the AC unit to lose its coolant and overheat. To check for leaks:

1. Turn off the thermostat of your AC unit.

2. Locate the low pressure service port. It will be located on either the indoor or outdoor unit of the AC system.

3. Use a leak detector kit to check for leaks in the refrigerant line.

4. If there are any leaks, you will need to have them repaired by a professional AC technician.

5. Once the leaks are repaired, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Clean the outdoor unit

The outdoor unit of an AC system can become dirty over time, which can restrict air flow and cause the unit to overheat and shut down. To clean the outdoor unit:

1. Turn off the thermostat of your AC unit.

2. Locate the outdoor unit of the AC system. It will be located outside, usually on a concrete pad or in a garden area.

3. Inspect the outdoor unit for dirt and debris build-up.

4. If there is dirt and debris build-up, use a garden hose to spray off the unit. Be sure to disconnect any electrical power to the outdoor unit before doing this!

5. Once the outdoor unit is clean, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Check the AC compressor

The AC compressor is responsible for circulating the refrigerant through the AC system. If this component fails, it can cause the AC unit to overheat and shut down. To check the AC compressor:

1. Turn off the thermostat of your AC unit.

2. Locate the outdoor unit of the AC system. It will be located outside, usually on a concrete pad or in a garden area.

3. Inspect the AC compressor for any signs of damage.

4. If the AC compressor is damaged, you will need to have it replaced by a professional AC technician.

5. Once the AC compressor is replaced, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Inspect the AC fans and blower 

The AC fans and blower help to circulate the air through the AC system. If these components are not working properly, it can cause the AC unit to overheat and shut down. To inspect the AC fans and blower:

1. Turn off the thermostat of your AC unit.

2. Locate the indoor and outdoor units of the AC system.

3. Inspect the indoor and outdoor fans for any signs of damage.

4. If the fans are damaged, you will need to have them replaced by a professional AC technician.

5. Once the fans are replaced, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Test AC thermostat 

The AC thermostat is responsible for regulating the temperature of the AC system. If this component is not working properly, it can cause the AC unit to overheat and shut down. To test the AC thermostat:

1. Turn off the thermostat of your AC unit.

2. Locate the AC thermostat. It will be located in the indoor unit of the AC system.

3. Inspect the AC thermostat for any signs of damage.

4. If the AC thermostat is damaged, you will need to have it replaced by a professional AC technician.

5. Once the AC thermostat is replaced, turn on your AC unit at the thermostat and check to see if it is cooling properly.

 

Check for obstructions 

If there is an obstruction in the path of the air flow, it can cause the AC unit to overheat and shut down. To check for obstructions:

1. Turn off the thermostat of your AC unit.

2. Locate the indoor and outdoor units of the AC system.

3. Inspect the area around the units for any obstructions.

4. If you find an obstruction, remove it and turn on your AC unit at the thermostat.

5. If the AC unit is still not working properly, you may need to contact a professional AC technician for further assistance.

 

Conclusion

 

If your Air Conditioner not blowing cold air but running or ac cooler not working, there are a few things you can do to troubleshoot the issue. First, check the evaporator coil and the AC compressor. If these components are damaged, you will need to have them replaced by a professional AC technician. Next, check the AC fans and blower. If these components are not working properly, they can cause the AC unit to overheat and shut down. Finally, check the AC thermostat. If this component is not working properly, it can cause the AC unit to overheat and shut down. If you have followed all of these tips and your AC unit is still not working properly, you may need to contact a professional AC technician for further assistance.
