Goodman Central Air System Not Cooling

Common Issues with Goodman Central Air Systems

Unit Not Turning On

If your Goodman air conditioner isn’t turning on, it could be due to several issues that you can often resolve on your own before calling in a technician. First, check your home’s fuse box or circuit breaker. It’s possible that the circuit has tripped; if so, reset it and check if your unit turns on. Next, locate the reset button on your unit. This can sometimes resolve minor electrical glitches. Finally, ensure that both your thermostat and the air conditioner unit are receiving power. This may involve checking any external switches or inspecting power cords and connections.

Weak Airflow

Weak airflow from your Goodman air conditioner can significantly impact your comfort and the efficiency of your system. One of the most common culprits is a dirty air filter. Check and replace or clean your air filter regularly to ensure it isn’t clogged with dust and debris, which can obstruct airflow. Additionally, ensure that all vents in your home are open and free from obstructions like furniture or curtains. Finally, inspect your ductwork for any signs of clogs or leaks. A clogged or leaky duct can impede airflow and cause your system to work harder, which might lead to further issues.

Not Blowing Cold Air

If your Goodman air conditioner is running but not cooling the air, there are several potential issues to consider. First, check your thermostat settings to ensure it is set to “cool” and “auto” mode. This ensures your system is programmed to cool air. If the air filter is dirty, it can restrict airflow and inhibit the system’s ability to cool the air effectively. Replace the air filter if you notice it’s saturated with dust and dirt. Another issue could be low refrigerant levels, which are crucial for cooling the air. Low refrigerant may suggest a leak, which requires professional repair to ensure your system returns to optimal functioning.

Frozen Evaporator Coil

A frozen evaporator coil can seriously hinder your Goodman air conditioner’s ability to cool your home. If you notice frost on the evaporator coil, turn off your system immediately to allow the coil to thaw. This issue often arises from reduced airflow due to dirty air filters or blocked air return grilles. Ensure that you replace or clean your air filter and check that nothing is blocking the flow of air to your system.

Leaking Water

Seeing water around your Goodman air conditioner can be alarming. This often happens when the drain line is blocked. You can clear the line using a garden hose or a shop vac to remove any debris. Another common issue is an overflowing drain pan, which should be emptied and cleaned regularly to prevent water overflow. Additionally, a dirty air filter can cause ice to form on the coils, which when melts, results in excess water that your system might not be equipped to handle.

Advanced Troubleshooting Tips

Checking Refrigerant Levels

Cooling problems in your Goodman air conditioner might be due to refrigerant issues. To check the refrigerant levels, you can use a manifold gauge set to measure the pressure. If the levels are low, this could indicate a leak. Since handling refrigerant requires special skills and equipment, it is advisable to consult a professional if you suspect a leak or if the refrigerant charge does not match the specifications.

Inspecting the Ductwork

The efficiency of your Goodman air conditioner heavily depends on the condition and setup of your ductwork. Ensure that the ducts are correctly sized and properly connected to your unit. Check for any kinks, disconnections, or signs of wear and tear that could impair performance. Seal any leaks with duct tape or mastic sealant to maintain proper air pressure and flow throughout the system.

Evaluating the Thermostat

The thermostat acts as the control center of your air conditioning system. Verify that all settings are correct and that it is switched to the appropriate mode for cooling. If your thermostat is battery-operated, replace the batteries if you notice any power issues or irregularities in temperature control. For enhanced efficiency and control over your indoor climate, consider upgrading to a programmable or smart thermostat.

When to Call a Professional

If your troubleshooting efforts do not resolve the issue, it might be time to call a professional HVAC technician. Seek expert help if you encounter persistent problems despite following the steps outlined, or if you face complex issues such as refrigerant leaks or electrical faults. Additionally, it’s wise to have your system professionally inspected and maintained annually to ensure its long-term efficiency and prevent unexpected breakdowns.

FAQ’s on Goldman Central Air System Issues

• Why won’t my Goodman air conditioner turn on? If your Goodman air conditioner won’t power up, start by checking your home’s fuse box or circuit breaker to see if the circuit has tripped. If so, reset it and try turning on your unit again. Next, locate and press the reset button on your air conditioner, which can often solve minor electrical issues. Finally, ensure that both the thermostat and the unit are properly connected to power sources.
• What should I do if my Goodman air conditioner has weak airflow? Weak airflow can be addressed by ensuring that your air filter is clean and free from debris. Check and replace or clean the air filter if it appears clogged. Also, make sure that all air vents are open and unblocked by furniture or curtains. Inspecting your ductwork for any leaks or blockages is also crucial, as these can significantly reduce airflow.
• How do I fix my Goodman air conditioner that is running but not blowing cold air? First, verify that your thermostat is set to “cool” and “auto” mode, which is essential for proper cooling operation. If the air filter is dirty, it can restrict airflow and reduce the efficiency of your system; replace it if necessary. Another common issue could be low refrigerant levels, often indicated by ice formation or hissing noises at the unit. If you suspect a refrigerant leak, it’s advisable to contact a professional technician for repairs.
• What causes a Goodman air conditioner’s evaporator coil to freeze? A frozen evaporator coil in your Goodman air conditioner typically results from reduced airflow, which prevents the coil from absorbing enough heat. This can be due to a dirty air filter or blocked air return grilles. To resolve this, turn off the unit to allow the coil to thaw, and then address the airflow issues by cleaning or replacing the air filter and ensuring all air pathways are clear.
• How can I stop my Goodman air conditioner from leaking water? Water leaks in air conditioning units often stem from a blocked drain line or an overflowing drain pan. You can clear the drain line using a garden hose or a shop vac to remove any obstructions. Additionally, regularly empty and clean the drain pan to prevent overflow. Another preventative measure is to replace the air filter if it’s dirty, as this can cause ice build-up on the coils, which melts and leads to leakage when the ice thaws.
