When the weather gets really hot in San Diego, the last thing you need is a broken air conditioner. Many common problems with air conditioning systems can arise, and at Atlas HVAC Inc., we want you to be aware, prepared, and ready for these air conditioning issues. This blog lists common AC problems and solutions so you and your family can stay cool when the summer months are here.

Inconsistent Cooling

Are some of your rooms too cold while others are still warm? This is an example of inconsistent cooling. Factors like the age and design of your home can cause these consistency issues, but there might also be a leak in your duct system. One of our trained professionals can inspect your air conditioner and duct system to suggest solutions for this problem. 

Failure to Cool

A few things can cause your air conditioner to blow warm air. One simple thing to check is the system’s filter. Dirty filters can prevent your system from functioning properly and decrease its efficiency. The good thing is that they are easy to change. You can save 5 to 15 percent of the energy used for your air conditioning by changing your filter. Some other solutions are to clean the condenser coils or have our team come out and add refrigerant to your air conditioner if there is a leak. Other mechanical failures can cause other cooling issues. 

The best way to ensure your air conditioner is ready for the warm season is to have regular maintenance performed. Our highly trained professionals can thoroughly inspect, clean, and tune up to ensure all system components are running well.

No Air Blowing

When you feel no air blowing out of your unit, even when it is turned on, you may have a broken fan, thermostat, or tripped breaker. It’s easy to fix your tripped breaker, and you can inspect your unit to see if the fan is running. Other less common issues may be a bad blower belt or wiring issues. 

Common AC Problems and Solutions


If you notice ice accumulating around your air conditioning unit, it is because your air conditioner is freezing up. Check that there is good airflow through and around your air conditioning system. Dirty air filters, closed dampers, or blocked vents can restrict airflow. If all of these areas seem clear, but ice is still forming, call our trained team to conduct a more professional check of your system. 

Strange Noises

If you hear strange noises coming from your system, they are cues something needs to be repaired or replaced. Squeaking sounds indicate problems with the air conditioner belt. Grinding sounds mean you might need to inspect the motor’s bearings. Other noises like rattling may be easier to remedy because this means a cover is just loose.

Odd Operation Patterns

Your air conditioner should kick on at a certain temperature, run for a while, and then shut off when your desired temperature is hit. If your air conditioner constantly runs or seems to cycle on and off too frequently, there might be an internal issue. When your air conditioner constantly runs, there could be an issue with the fan, refrigerant level, or relay switches. A member of our team can diagnose and repair these issues. A system constantly turning off and on may indicate a dirty or blocked condenser unit or evaporator. A thorough cleaning can solve this issue.
