As the summer heat intensifies in Spokane Valley, WA, a malfunctioning air conditioner can quickly turn your home into an uncomfortable sauna. If you find yourself asking, “Why is my AC not blowing cold air?” it’s time to investigate the issue and find a solution. Mainstream Electric, Heating, Cooling, & Plumbing, a trusted provider of HVAC services in the Inland Northwest since 2000, is here to help you diagnose and resolve the problem.

Common Reasons Your AC Isn’t Cooling Properly

There are several reasons why your air conditioner may not be blowing cold air, ranging from simple fixes to more complex issues requiring professional attention. Some of the most common culprits include:

  1. Dirty Air Filter: A clogged air filter restricts airflow, causing your AC to work harder and less efficiently. Regularly replacing your air filter can prevent this issue and improve your system’s performance.
  2. Thermostat Settings: Ensure your thermostat is set to “cool” and at a temperature lower than the current room temperature. If your thermostat is malfunctioning, it may need to be recalibrated or replaced.
  3. Refrigerant Leaks: Low refrigerant levels due to leaks can hinder your AC’s ability to cool effectively. Leaks should be addressed by a certified HVAC technician to restore proper refrigerant levels and prevent further damage.
  4. Frozen Evaporator Coil: A dirty air filter, low refrigerant, or blocked airflow can cause the evaporator coil to freeze, preventing your AC from cooling properly. Thawing the coil and addressing the underlying issue is crucial.
  5. Compressor Issues: As the heart of your AC system, a faulty compressor can lead to inadequate cooling. Compressor problems often require professional diagnosis and repair.

Troubleshooting Tips for Spokane Valley Homeowners

Before calling in the professionals, there are a few steps you can take to troubleshoot your AC:

  1. Check and replace your air filter if it’s dirty or clogged.
  2. Verify your thermostat settings and batteries.
  3. Clear any debris around your outdoor unit to ensure proper airflow.
  4. Check for visible signs of refrigerant leaks, such as ice on the refrigerant lines or hissing sounds.

If these steps don’t resolve the issue, it’s time to call in the experts at Mainstream.
