Air conditioners must be tuned to experience better performance and enjoy the pollution-free cold air. If your AC is not blowing cold air, there are several reasons behind it. Here are some of the reasons why your air conditioner’s not blowing cold air:
- Dirty air filter
- Thermostat set to “ON” instead of “Auto”
- Air duct leak
- Dirty evaporator coils
- Refrigerant leak
- Circuit breakers trip
Why Is the Air Conditioner Running but Not Cooling the House?
You must check your thermostat settings if your AC is not cooling but running 24/7. If your thermostat is set to “ON”, your air conditioner will run at all times even if it’s not cooling the air. If your thermostat is set to “Auto”, it will make sure that your fan only runs when your air conditioner is cooling the air.
Why is Your Air Conditioner Not Blowing Out Cold Air?
A dirty air filter blocks the airflow to your air conditioner, which can freeze up the condenser unit and limit your AC’s cooling power. You should change your air filter every month to enjoy better performance.
What to Do When Your Air Conditioner Is Not Cooling
Refrigerant is necessary to cool the air inside your home and needs regular maintenance. If not maintained properly, the unit will develop leaks. If there is insufficient refrigerant in your air conditioning system, your home will feel warmer. You should schedule an air conditioning tune-up with an HVAC technician for checking refrigerant leaks.
What Is the Right Temperature for Air Conditioners in Summer?
To stay cool and save money this summer, you should set your thermostat to 78 degrees when you are at home. If you are out of your home for more than 2 hours, then you should raise the thermostat settings to 88 degrees to keep your house warmer and save on cooling costs.
How Cold Is Too Cold for Air Conditioning?
If your AC reduces your home’s temperature by more than 20 degrees, the air blowing out will feel frigid and uncomfortable. No doubt, the air inside your home will cool down, but you will need a blanket whenever your AC is in a cooling cycle.

In warmer climates like Orange County, poor insulation or extreme outdoor temperatures can cause cooled air to dissipate quickly. Proper insulation helps maintain indoor comfort and improves your air conditioner’s efficiency.
What initial troubleshooting steps can I take if my air conditioner is not consistently blowing cold air?
Before calling a professional, check your thermostat settings, ensure vents are unobstructed, and inspect for visible issues like frozen coils or unusual noises. These steps can help identify simple fixes or signal the need for professional maintenance by White Mechanical, Inc.
How does regular HVAC tune-up service improve my AC’s cooling efficiency?
Regular maintenance from professionals like White Mechanical, Inc. ensures your system is operating at peak performance, helping detect issues such as refrigerant leaks or ductwork problems before they lead to reduced cooling efficiency.
What are common signs that my evaporator coils might need cleaning or repair?
If you notice uneven cooling, frost buildup, or a drop in performance, it could indicate that the evaporator coils are dirty or damaged, requiring professional cleaning or repair to restore full efficiency.
How do duct leaks contribute to my AC not blowing cold air?
Leaky ducts allow cooled air to escape before reaching your living areas, resulting in warmer indoor temperatures. Sealing these leaks can significantly improve overall cooling performance.
What should I consider when selecting the right size air conditioner for my home?
Choosing the proper AC size involves evaluating your home’s square footage, insulation, and local climate. An improperly sized unit can lead to inefficient cooling and higher energy bills.
How does Orange County’s climate influence air conditioning performance?
The warm and sometimes unpredictable climate in Orange County demands robust AC systems and regular maintenance. This ensures your system keeps up with cooling needs during peak heat while operating efficiently.
