Common Reasons Your AC Isn’t Cooling
When your air conditioner stops cooling your home, it could be due to several issues. Here are some common reasons you might be experiencing problems with your AC:
1. Thermostat Issues
A malfunctioning thermostat can prevent your AC from cooling properly. Ensure that the thermostat is set to the correct temperature and mode. Sometimes, a simple reset can resolve the issue.
2. Dirty Air Filters
Air filters that are clogged with dust and debris can restrict airflow, reducing your AC’s efficiency. Regularly cleaning or replacing the filters can help maintain optimal performance.
3. Refrigerant Leaks
Low refrigerant levels caused by leaks can significantly impact your AC’s ability to cool your home. If you suspect a refrigerant leak, it’s essential to call a professional for repair and recharging.
4. Blocked Condenser Unit
The outdoor condenser unit can become blocked by dirt, leaves, or debris, hindering airflow and heat exchange. Regularly inspect and clean the area around the unit to ensure proper function.
5. Electrical Problems
Faulty wiring or electrical components can disrupt the AC’s operation. Electrical issues require the attention of a professional to ensure safety and proper repairs.
Understanding these common issues can help you identify and resolve minor problems before they escalate. For more detailed information about air conditioning issues, visit our Air Conditioning Services page.

DIY Troubleshooting Tips
Before calling a professional, you can try some simple troubleshooting steps to see if you can resolve the issue yourself. Here are a few tips to help get your AC cooling again:
1. Check and Adjust the Thermostat
Ensure that the thermostat is set to the correct cooling mode and temperature. If the display is blank or unresponsive, it might need new batteries or a reset. Double-check the settings to ensure they match your desired cooling preferences.
2. Clean or Replace Air Filters
Dirty air filters can impede airflow and reduce cooling efficiency. Locate the air filter in your system, remove it, and clean or replace it if it’s dirty. Regularly maintaining the air filter can help keep your system running smoothly.
3. Inspect the Outdoor Unit for Obstructions
Go outside and check the condenser unit for any visible debris, such as leaves or dirt. Make sure there is at least two feet of clearance around the unit to allow proper airflow. You can gently hose down the unit to remove dirt and dust buildup, but be careful not to damage the fins or other components.
4. Check for Tripped Circuit Breakers
If your AC isn’t turning on at all, check your electrical panel for tripped circuit breakers. Reset any that may have tripped, but if they continue to trip, it could indicate a more serious electrical issue requiring professional attention.
While these DIY tips can help with minor issues, persistent problems may require professional intervention. Our team at Chisholm Plumbing, Heating & Air Conditioning offers comprehensive AC maintenance in Greer to keep your system running efficiently year-round.

When to Call a Professional
While DIY troubleshooting can resolve some issues, certain situations require the expertise of a professional HVAC technician. Here are some signs that it’s time to call in the experts:
Persistent Cooling Issues
If your AC continues to struggle to cool your home despite your troubleshooting efforts, it may indicate a more serious underlying problem that requires professional diagnosis and repair.
Strange Noises or Odors
Unusual noises like grinding, squealing, or banging, or strange odors coming from your AC system, can signal mechanical issues or mold growth. These should be addressed by a professional to prevent further damage.
Frequent Cycling On and Off
If your AC frequently turns on and off, it could be experiencing short cycling. This issue can increase energy consumption and reduce the lifespan of your system, requiring professional attention.
Increasing Energy Bills
A sudden spike in your energy bills without a change in usage could indicate that your AC is not operating efficiently. A professional technician can assess your system and recommend solutions to improve efficiency.
Regular maintenance can prevent many of these issues and keep your system running efficiently. If you’re experiencing any of these signs, consider scheduling a service with Chisholm Plumbing, Heating & Air Conditioning.
