Air Conditioning

If your AC is running but not cooling, it can be frustrating, especially on a hot day. Here are some common causes for this issue and how to address them:

1. Dirty Air Filter

• Restricted Airflow: A clogged or dirty air filter can significantly reduce airflow, making it harder for your air conditioner to cool the air effectively. When airflow is blocked, your AC may continue to run but won't cool the space properly.
• Solution: Replace or clean the air filter to restore proper airflow.

2. Low Refrigerant Levels

• Refrigerant Leak: Refrigerant is the substance that absorbs and releases heat in your AC system. If the refrigerant level is low due to a leak or other issue, the AC won’t be able to cool the air efficiently, even though it's running.
• Solution: A professional technician will need to check for refrigerant leaks, repair any leaks, and recharge the system with the appropriate amount of refrigerant.

3. Dirty or Blocked Coils

• Dirty Evaporator or Condenser Coils: The evaporator and condenser coils are responsible for absorbing and releasing heat. If they are dirty or clogged with dust and debris, they can’t perform their job effectively, causing the system to run inefficiently and fail to cool the air.
• Solution: Regularly clean the coils or have a professional clean them to ensure proper heat transfer.

4. Thermostat Malfunction

• Incorrect Temperature Settings: If your thermostat is not functioning properly or is incorrectly calibrated, it might be sending wrong signals to the AC system, causing it to run but not cool the air.
• Solution: Check the thermostat settings to ensure they are correct. If the thermostat is malfunctioning, it may need to be replaced or recalibrated.

5. Frozen Evaporator Coils

• Icing Over: If the evaporator coils freeze, the AC system will not be able to absorb heat effectively, and it will blow warm air. This can be caused by a dirty air filter, low refrigerant levels, or poor airflow.
• Solution: Turn off the AC and let the coils thaw. Check the air filter, and clean or replace it. If the coils freeze frequently, contact a technician to check for refrigerant leaks or other underlying issues.

6. Faulty Compressor

• Compressor Issues: The compressor is responsible for circulating the refrigerant through the system. If the compressor is faulty or damaged, it won’t be able to cool the air properly, even though the system may still run.
• Solution: A malfunctioning compressor usually requires professional repair or replacement.

7. Electrical Issues

• Faulty Components: Electrical problems, such as a malfunctioning capacitor or wiring issues, can cause the system to run but fail to cool the air. In this case, the fan or compressor may not be working properly.
• Solution: If you suspect an electrical issue, it’s best to call an HVAC professional to inspect and repair the system.

8. Low or Poor Airflow

• Blocked Vents or Ductwork: If there are blockages in your air vents or ductwork, or if the ducts are leaking, airflow will be restricted, and your AC won’t be able to distribute cool air effectively.
• Solution: Check for any blockages or obstructions in the vents and ducts. If necessary, have a professional inspect and seal any ductwork leaks.

9. Wrong-Sized AC Unit

• Unit Too Small for the Space: If your AC unit is undersized for your space, it will struggle to cool the area, even if it's running. It may run constantly without achieving the desired temperature.
• Solution: A professional technician can assess whether your AC unit is properly sized for your space. If it’s too small, you may need to upgrade to a larger unit.

10. Capacitor or Fan Issues

• Malfunctioning Fan or Capacitor: The fan helps distribute cool air, and the capacitor helps start the compressor and fan. If either of these components fails, the AC may run but won’t cool the air effectively.
• Solution: If the fan or capacitor is faulty, they will need to be replaced by a professional technician.

What to Do:

If your AC is running but not cooling, start by checking the air filter and thermostat settings. If these are fine and the issue persists, it’s best to contact a professional like Mannix Heating & Air Conditioning to inspect the system. They can diagnose the issue, check for refrigerant leaks, clean coils, or address any other underlying problems to get your AC cooling again efficiently. Regular maintenance, such as cleaning filters and checking refrigerant levels, can also help prevent these issues from occurring in the future.

If your air conditioner is leaking water, it can be due to several common issues. Here are some potential causes and solutions to address the problem:

1. Clogged Condensate Drain Line

• Cause: The condensate drain line carries excess moisture (condensation) away from your AC unit. Over time, the line can get clogged with dirt, algae, mold, or debris, causing water to back up and leak inside your home.
• Solution: Clear the condensate drain line to ensure proper drainage. You can try flushing it with a mixture of water and vinegar to break up any buildup, or you may need to call a professional to clean the line thoroughly.

2. Frozen Evaporator Coils

• Cause: If the evaporator coils freeze, the ice will eventually melt, and water will leak from the AC unit. Frozen coils can occur due to restricted airflow (from a dirty air filter or blocked vents), low refrigerant levels, or a malfunctioning fan.
• Solution: Turn off the AC to let the coils thaw. Once thawed, check and replace the air filter, ensure proper airflow, and call a technician to check the refrigerant levels if necessary.

3. Dirty Air Filter

• Cause: A dirty air filter restricts airflow over the evaporator coils, which can cause them to freeze. As the ice melts, water may leak from the unit.
• Solution: Replace or clean the air filter regularly to ensure proper airflow and prevent freezing.

4. Improperly Installed or Disconnected Drain Pan

• Cause: The drain pan collects water that drips from the evaporator coils. If the drain pan is improperly installed, damaged, or disconnected, it can cause water to leak from the unit.
• Solution: Inspect the drain pan to ensure it’s properly positioned and intact. If it's damaged, it may need to be replaced. A technician can help with this.

5. Low Refrigerant Levels

• Cause: Low refrigerant levels can cause the evaporator coils to freeze. When the ice melts, it results in excess water that leaks from the AC unit. This usually occurs because of a refrigerant leak.
• Solution: If you suspect a refrigerant leak, contact a professional technician to locate and fix the leak, and then recharge the system with the correct amount of refrigerant.

6. Leaky Ductwork

• Cause: If there’s a leak in the ductwork, warm air can enter the ducts and cause condensation to form. The condensation can then drip and cause water to leak from the AC unit.
• Solution: Have a technician inspect the ductwork for leaks and repair them to prevent moisture buildup.

7. Blocked or Broken Drain Line

• Cause: If the condensate drain line is physically damaged or blocked (due to debris or a buildup of algae), it can prevent the water from draining properly, causing water to pool and leak inside the home.
• Solution: Inspect the drain line for damage and clear any debris or obstructions. If the line is broken, it may need to be replaced by a technician.

8. Improperly Sized AC Unit

• Cause: An oversized AC unit can cool the air too quickly and short cycle, which can lead to excessive condensation that the system can’t handle. This can cause the water to leak from the unit.
• Solution: If your unit is oversized for your space, you may need to replace it with a properly sized system. A technician can evaluate the size of the system to ensure it’s the right fit for your space.

9. Condensation During Humid Weather

• Cause: In very humid weather, your AC may produce more condensation than usual. If the condensate drain line is clogged or not functioning properly, this excess moisture can result in leaks.
• Solution: Ensure that the condensate drain line is clear and functioning correctly, and consider having the unit serviced during the peak of the humid season.

10. Faulty Pump

• Cause: If your AC unit has a pump to remove condensation and it’s malfunctioning, it can lead to water backup and leakage.
• Solution: If you suspect the pump is faulty, have a professional HVAC technician inspect and replace the pump if needed.
