Goodman Air Conditioner Not Blowing Hard – Quick Fix

A reduction in airflow causes your Goodman air conditioner to stop blowing hard. And a few issues reduce the airflow. Let us discuss each possible cause and how to fix them.

1. Flex Ducts

If your home has flex ducts, it is crucial to check them to ensure they are not crushed. Their flexibility and plastic material makes them fragile and easy to get damaged. When they are crushed due to a number of reasons, the airflow in your home significantly drops.

Locate the ducts at the top part of the house, most likely in the attic of the house. When you find the ducts, see if any item is pressing against them and restricting the flow of air. If the item is something you can remove yourself, move it out of the way. Otherwise, find someone to help or call a professional to fix it.

2. Damper

A damper opens and closes to measure the amount of air that flows into a particular area of the house. Since it is an electrically-controlled part of the cooling unit, it may stop working if there is a loss of power. As a result, the air conditioner will not blow air hard.

To fix this problem, check for the damper’s controls near the interior unit. From there, you can tell whether or not the damper is open. You can consult the user manual if you are unsure of the damper’s location. You can also opt to call an HVAC professional for further assistance.

3. Air Duct

The air duct may be leaking or become disconnected. Over time and with constant use, the duct can spring a leak or pull out of the connection. Hire a professional to check this problem and fix it if that is causing a reduction in airflow.

4. Evaporator Coil

Sometimes, the evaporator coil becomes frozen, especially when the temperature is too low. High humidity leads to moisture settling on the coil and freezing due to the cold temperature. 

Much like in a refrigerator, the accumulation of ice on the coil will muffle the flow of air from the air conditioner into your home. Water pooling by the interior unit is another clear sign that the coil is frozen and needs to be thawed.

Disconnect the air conditioner from electric power and wait for the ice on the coil to melt. It may take some time, depending on the amount of ice on it. Afterward, check to see if the air filter is dirty and in need of a replacement. Also, check the return grate and supply register to ensure they are open. Otherwise, the evaporator coil will freeze again.

5. Air Filter

Believe it or not, a dirty AC filter can negatively affect the airflow. This is apart from contaminating the air in your home, Typically, you should replace the air filter every three months. Some manufacturers recommend replacing the filter every month. In some cases, you can wash the filter, but it is always best to replace it, not wash it.

6. Blower

The blower has the job of pulling air from the surroundings, passing it over the evaporator coil to cool it, and pushing it back into your home. By then, the air is cold. However, the cold air will not flow as it should, and a defective air blower motor or a dirty blower wheel can cause this problem. A defective capacitor can also cause this problem, as well as a worn fan belt, but the latter is not common.

Consider cleaning the blower motor to remove dirt on it if it is dusty. But replace the blower motor if it is no longer working, so that it can resume its duties of supplying cold air in the home. If you cannot fix the blower yourself, get a professional to do a permanent fix for you.

7. Return Vent

The vent should be fully open for cold air to pass through into your home. Also, ensure nothing is blocking it, whether from the inside or outside. Open the vent and thoroughly clean it before checking if there is an improvement. 

If not, then the problem may stem from the vent being the wrong size for your home. Small vents in a big home will not spread enough air, making it seem as if the air conditioner is not working well. An HVAC professional should look at the size and see if it is something they can fix.

Note: When an air conditioner has a problem that causes it not to blow hard, it affects the compressor. You will find the compressor running too much to make up for the deficiency, consuming too much energy in the process. Energy consumption is another reason to fix this problem.
