- Inspect the power cord for any visible damage.
If you’ve determined that electrical issues are present, it may be wise to contact a professional electrician.
Look for Signs of Refrigerant Leaks
If you suspect a refrigerant leak, check for visible ice buildup on evaporator coils or listen for hissing sounds. Unfortunately, refrigerant issues typically require a technician’s expertise and specialized tools.
How to Communicate with Your Landlord
In an apartment setting, you’re generally not responsible for repairs to the AC unit. If you attempt troubleshooting and still find your system not working, it’s time to escalate the situation to your landlord or property management. Here’s how to effectively communicate the issue:
Document the Problem
Before contacting your landlord, make sure to document the respective problem:
- Take notes of the symptoms your AC unit is exhibiting.
- Record the temperature inside your apartment.
- Capture timestamps of when you attempted to troubleshoot.
This documentation serves as evidence of your attempts to resolve the issue independently.
Be Clear and Concise
When you approach your landlord, make sure to articulate your concerns clearly. Begin by stating the facts:
- Outline the issue with the AC unit.
- Mention any troubleshooting steps you have taken.
- Specify how long the unit has been malfunctioning.
A clear message makes it easier for your landlord to grasp the urgency of the situation.
When to Call a Professional
While the above troubleshooting steps are meant to empower you, sometimes the issue may be beyond a quick fix, and you’ll need to call a technician. Here are scenarios when professional intervention is necessary:
Persistent Issues
If the AC is still not operational after performing a thorough check of the thermostat, filters, and power supply, it’s best to consult a professional. Additionally, if refrigerant leaks are suspected, only a certified technician can handle this safely and correctly.
Unusual Noises
If you hear strange noises such as grinding, rattling, or banging when your AC is running, this could indicate serious mechanical problems. Don’t hesitate to contact a repair service to prevent further damage.
Preventive Measures for Future Problems
Take proactive steps to ensure your AC remains in optimal condition, reducing the likelihood of problems down the road.
Regular Maintenance
Setting a schedule for regular maintenance can do wonders for your air conditioning unit. This includes:
- Cleaning or replacing air filters every month, especially during peak usage seasons.

Final Thoughts
An air conditioning unit that’s not working can disrupt your comfort and quality of life, especially during sweltering summer months. Knowing how to troubleshoot and communicate effectively with your landlord can significantly ease your plight. If the problem persists, do not hesitate to seek the assistance of qualified professionals to restore your home to a comfortable living condition. With consistent maintenance and prompt attention to issues, you can keep your air conditioning running smoothly for years to come.
What should I do first if my AC stops working in my apartment?
If your AC stops working, the first step is to check your thermostat settings. Ensure that the temperature is set lower than the current indoor temperature and that it’s set to ‘cool’ mode. If your thermostat is battery-operated, try replacing the batteries. A reset might also be needed, so turn the system off for a few minutes before turning it back on.
Next, inspect your air filter. Clogged or dirty filters can restrict airflow, causing your AC system to freeze or malfunction. If the filter is dirty, replace it with a clean one. After these initial checks, if the AC still isn’t functioning properly, it may be time to contact your landlord or a professional technician.
