Is Your AC Not Cooling?
If your air conditioner is not blowing cold air but running, it can be frustrating—especially during the hot summer months in Salt Lake City, West Valley City, Sandy, South Jordan, Draper, and Bountiful. This common issue can stem from several causes, including clogged air filters, low refrigerant levels, or a malfunctioning compressor. Understanding these problems can help you determine if a simple fix is possible or if you need professional AC repair services.
Common Reasons Your AC Is Running but Not Cooling
1. Dirty or Clogged Air Filter
A clogged air filter restricts airflow, preventing your AC from cooling your home efficiently. Regular HVAC maintenance can help ensure your filters are clean and your system is working optimally.
2. Low Refrigerant Levels
If your system is low on refrigerant, your AC might run but fail to cool properly. This often indicates a leak, which requires a licensed HVAC technician to diagnose and repair.
3. Frozen Evaporator Coils
If ice builds up on the evaporator coils, it can block airflow, making your AC ineffective. Routine AC maintenance can prevent this problem by ensuring coils remain clean and free of debris.
4. Malfunctioning Compressor
The compressor is the heart of your air conditioning system. If it’s not working correctly, your AC won’t cool. A professional air conditioning repair service can inspect and replace a failing compressor if needed.
5. Blocked or Leaky Ductwork
Leaks or blockages in your ductwork can prevent cool air from reaching your rooms. Ductwork inspection and repair can help restore proper airflow.
How to Fix an AC That’s Not Blowing Cold Air

FAQs
Should I turn the AC off if it’s not cooling?
Yes, if your air conditioner is not blowing cold air but running, turning it off can prevent further damage. A struggling AC can overheat, freeze up, or put unnecessary strain on the compressor. Check for a clogged air filter, thermostat settings, or ice buildup on the evaporator coils. If the problem persists, it’s best to call a professional for AC repair services.
How do I reset my central AC if it’s not blowing cold air?
To reset your central air conditioning system:
- Turn off the thermostat.
- Switch off the power to your AC unit at the breaker box.
- Wait five minutes to allow the system to reset.
- Turn the power back on and set your thermostat to “cool.”
If your AC still won’t blow cold air, there may be a refrigerant leak, compressor issue, or frozen coils. A professional HVAC technician can diagnose and fix the problem.
How do I know if my AC refrigerant is low?
Low refrigerant levels can cause your air conditioner to run but not cool your home. Signs of low refrigerant include:
- Warm air blowing from vents
- Hissing or bubbling noises from the AC unit
- Ice buildup on the refrigerant lines
- Higher energy bills due to the system overworking
If you suspect low refrigerant, contact an HVAC professional for a refrigerant recharge and leak detection service.
How do I fix a blocked or clogged condenser coil?
A dirty condenser coil can reduce cooling efficiency. To clean it:
- Turn off the power to your AC unit.
- Remove debris like leaves or dirt from around the outdoor unit.
- Use a garden hose to gently spray the coils. Avoid high pressure.
- Apply a coil cleaner and let it sit for a few minutes.
- Rinse thoroughly and allow it to dry before restoring power.
If your AC is still struggling to cool, professional AC maintenance may be needed to fully clean and inspect the system.
How do I unfreeze my AC coils?
If your AC coils are frozen, turn the system off immediately to prevent damage. Then:
- Turn the fan on at the thermostat to help thaw the ice.
- Check and replace the air filter if it’s dirty.
- Inspect the refrigerant levels—low refrigerant can cause freezing.
- Allow the coils to thaw completely before turning the system back on.
If your AC keeps freezing, it could indicate a refrigerant leak, airflow restriction, or malfunctioning blower fan. A licensed HVAC technician can diagnose and fix the issue to prevent further breakdowns.
