You can hear your AC running, but your home isn’t cooling down. The vents are pushing out air—but it’s not cold. Sound familiar? If your air conditioner is not blowing cold air but running, you’re not alone. This is a common problem among homeowners in Fort Smith, Van Buren, and Alma, Arkansas, especially during the hottest months of the year.
Fortunately, the team at Riverside Comfort Care is here to help. In this blog, we’ll cover the most likely reasons your AC is acting up, what you can check yourself, and when it’s time to call a professional for help.
Top Reasons Your Air Conditioner Is Running but Not Cooling
If your AC is running but the air isn’t cold, there’s usually a specific cause behind the issue. Here are some of the most common culprits:
Wrong Thermostat Settings
Start with the easiest fix. Make sure your thermostat is actually set to “Cool” mode. Sometimes it may be left on “Fan,” which will run the blower without engaging the compressor—meaning no cold air. Also double-check your temperature setting and replace the batteries if needed. Even smart thermostats can get stuck in the wrong mode after a power flicker or power outage.
Clogged or Old Air Filter
A dirty filter can block airflow and cause the system to overheat or freeze up. When airflow is restricted, your air conditioner might still run but fail to deliver cold air. Try replacing your filter and see if it improves performance. This is especially important in homes with pets, smokers, or recent renovation work.
Low or Leaking Refrigerant
Refrigerant is essential for cooling. If your system is low on refrigerant due to a leak, it can’t absorb heat from the air properly. You might even see ice forming on the lines or evaporator coil. This requires professional repair and recharge, not a DIY fix.

Blocked or Dirty Condenser Coils
The outdoor condenser unit plays a critical role in releasing heat from your home. If the coils are clogged with dirt, leaves, or debris, it can limit your AC’s cooling power. Clear away visible obstructions and gently hose off the unit—but avoid damaging the fins. Routine maintenance can prevent this issue from cropping up in the middle of summer.
Electrical or Sensor Malfunctions
Faulty capacitors, control boards, or temperature sensors can prevent the compressor from activating even if the fan runs. If you hear the fan but don’t feel any change in temperature, an internal component could be failing. This type of issue typically requires an experienced HVAC technician to diagnose and fix.
DIY Troubleshooting Steps You Can Try First
Before calling for AC repair, try these basic troubleshooting tips:
- Switch to Cool mode and lower the temperature
- Replace your air filter if it’s dirty or hasn’t been changed in a while
- Inspect the outdoor unit for blockages or visible damage
- Check your circuit breaker to ensure it hasn’t tripped
- Look for ice on the indoor coil or outdoor line set
If none of these steps help, it’s time to reach out to the pros at Riverside Comfort Care.
