AC Running But Not Cooling? Here’s What To Do

When your air conditioning unit is running but not cooling, it can be incredibly frustrating. The hot Arizona summers make this issue even more unbearable as the heat outside intensifies. But if you’re dealing with a malfunctioning AC unit, there are some simple steps you can take to diagnose and repair the problem. Here’s what to do when your AC running but not cooling.

Check Your Thermostat

The first thing to do when your AC running but not cooling is to check your thermostat. If your thermostat is set too high, the AC won’t kick on and won’t cool the home. Make sure that the thermostat is set to the temperature you desire and that it’s not set to “heat” instead of “cool”.

If your thermostat checks out and you’ve manually switched the fan on, it’s time to call in a professional.

Check the Air Filter

The air filter in your HVAC system can become clogged with dust and other particles, preventing airflow. This means that the cooled air won’t be able to circulate in the home, resulting in your AC not cooling.

To check thefilter, simply remove it and examine it. If it’s covered with dirt, you can clean it or replace it. You may want to buy a pack of air filters and keep them on hand, just in case. Check your air filters once a month and replace them annually, or whenever they become caked with dirt.

Call a Professional

After you’ve checked the thermostat and the air filter, it’s time to call in the professionals. Trained experts will be able to pinpoint the cause of your AC issues and help you repair it, or present you with other solutions, such as replacing your unit.

Troubleshooting Tips

Before calling a professional, here are some tips to troubleshoot your AC on your own:

  • Check the condenser unit, which is usually located outdoor. Make sure it’s free of any debris, such as leaves and dirt.
  • Ensure that the fan is running. The fan should be on but not too loud.
  • Check for any frozen ducts or coils on the unit.
  • Make sure that the power switch is on.
  • Check the circuit breaker. If the breaker has been tripped, reset it to see if the AC will run.

AC Running but Not Cooling – Recommendations for Prevention

Temperature is a crucial factor for comfort and it can greatly affect our well being and productivity. That’s why when our air conditioners aren’t running properly, it’s important to take preventive action as soon as possible. Whether you’re facing AC running but not cooling problems, or other issues related to installation, there are several steps you can take to help solve the issue. Here are some recommendations that manufacturers, local appliance companies, and HVAC technicians offer to help you prevent AC running but not cooling issues.

Check the Unit

The first step in preventing AC running but not cooling problems is to make sure the unit is installed properly. Inspect the AC unit to make sure it is securely mounted, and all electrical connections and refrigerant lines are secure. If any component appears to be old, worn, or not working properly, replace it as soon as possible.

Schedule Regular Maintenance

It’s important to schedule regular maintenance for your air conditioning unit on an annual basis. During a regular maintenance check, a technician can check for signs of wear and tear, test the AC unit’s performance, and make sure the unit is running properly. If a malfunction is detected early, it can be fixed before it becomes a bigger problem.

Replace Filters

Air filters should be replaced every three months, or as recommended by the manufacturer. A dirty filter can restrict airflow and cause your air conditioner to run without cooling the house effectively. Make sure you use the right type of filter for your AC unit and that you change it when needed.

Check Refrigerant Levels

Your air conditioner needs the right amount of refrigerant to operate correctly. If the levels of refrigerant are low, it could cause your AC to run without cooling the air. Have a professional technician check the levels of refrigerant and top off the levels as needed.

Clean the Condenser Coils

It’s essential to clean the outside condenser unit on a regular basis. The condenser coils can become clogged up with dirt and debris, making the unit inefficient and preventing it from cooling the home properly. Use a soft bristled brush or vacuum to remove debris from the outside condenser unit.

Make Repairs as Needed

If your AC unit is still not running or cooling properly after doing the above steps, you may need to call in an HVAC technician to troubleshoot and make repairs. A professional technician can detect other problems, such as worn-out parts, that may be preventing your AC from running correctly.

By following these recommendations, you can help prevent AC running but not cooling problems. If you’re having issues with your current AC unit, it’s important to call a reliable HVAC technician to make repairs or replace the unit as needed. For any AC related problems, it’s best to contact a local Reliable Air Conditioning & Heating service to get the job done right.
