A broken air conditioning (AC) unit can turn a comfortable home into a sweltering oven, especially during the hot summer months. Whether your AC is blowing warm air, making strange noises, or not turning on at all, knowing how to troubleshoot and fix common issues can save you time, money, and discomfort. This guide provides six useful tips for fixing broken AC units, helping you restore comfort to your home efficiently and effectively.
When to call professional help
While DIY solutions can resolve many AC issues, there are times when calling professional help is essential. If your AC unit continues to malfunction despite your efforts, or if you encounter complex problems like refrigerant leaks, electrical issues, or significant mechanical failures, it’s time to consult an HVAC professional. Whether you are looking for an ac repair Rockwall or any other place, trained technicians have the expertise and specialized tools to diagnose and fix problems safely and efficiently. They can also perform comprehensive maintenance checks to prevent future issues.
Additionally, attempting to repair more complicated problems without proper knowledge can result in further damage and higher repair costs. Ensuring your AC unit is serviced by a professional not only restores comfort to your home but also extends the lifespan of your system, providing peace of mind and reliable performance.
Identify the problem
The first step in fixing a broken AC unit is identifying the problem. Common issues include a lack of cold air, unusual noises, leaks, and the unit not turning on. Begin by checking the thermostat settings to ensure they are correctly set to “cool” and that the temperature is lower than the current room temperature. Next, inspect the air filter; a dirty or clogged filter can significantly impact the AC’s performance. Listen for any unusual sounds that might indicate a mechanical issue, such as a loose part or a failing motor. By pinpointing the exact problem, you can narrow down the potential solutions and avoid unnecessary repairs.
Clean or replace the air filter
One of the simplest yet most effective maintenance tasks for an AC unit is cleaning or replacing the air filter. Over time, filters accumulate dust, dirt, and debris, restricting airflow and reducing efficiency. A clogged filter can cause the AC to work harder, leading to higher energy bills and potential damage to the unit. To clean or replace the filter, first, turn off the AC. Locate the filter, which is usually found behind the front grille or in the return air duct. If it’s a reusable filter, clean it with water and let it dry completely before reinstalling. For disposable filters, replace them with a new one that matches the size and type specified by the manufacturer.
Check the thermostat
The thermostat is the AC unit’s control center, and if it’s malfunctioning, the entire system can be affected. Ensure that the thermostat is set to the correct mode (cooling) and that the temperature setting is appropriate. If the thermostat is battery-operated, replace the batteries and see if that resolves the issue. For programmable thermostats, review the settings to ensure they haven’t been inadvertently changed. If the thermostat still doesn’t seem to be working correctly, it might need recalibration or replacement. Consider upgrading to a smart thermostat, which can provide better control and efficiency.
Inspect and clean the coils
The evaporator and condenser coils are critical components of your AC unit. Over time, these coils can become covered in dirt and grime, reducing their ability to absorb and dissipate heat. To clean the coils, first, turn off the power to the AC unit. For the evaporator coils, access them by removing the panel on the indoor unit. Use a soft brush or a specialized coil cleaner to remove dirt and debris. For the condenser coils, located in the outdoor unit, remove any debris and gently clean the coils with a garden hose, being careful not to bend the fins. Regularly cleaning the coils can improve efficiency and extend the life of your AC unit.
Clear the condensate drain
A clogged condensate drain can cause water to back up and potentially damage your AC unit or home. The drain line can become clogged with algae, mold, or debris, leading to water leaks and reduced efficiency. To clear the drain, locate the condensate drain line, usually found near the indoor unit. Use a wet/dry vacuum to remove any blockage from the line. You can also use a mixture of water and vinegar to flush the line and kill any algae or mold. Keeping the condensate drain clear is essential for maintaining proper AC function and preventing water damage.
Ensure proper airflow around the outdoor unit

The outdoor unit of your AC system needs adequate airflow to function efficiently. Overgrown vegetation, debris, and other obstructions can restrict airflow and cause the unit to overheat. Regularly inspect the area around the outdoor unit and remove any leaves, branches, or debris. Trim back any plants or shrubs to ensure at least two feet of clearance on all sides. Additionally, check the condition of the fins on the outdoor unit and straighten any that are bent. Proper airflow around the outdoor unit is crucial for optimal performance and energy efficiency.
Fixing a broken AC unit can seem daunting, but with these six useful tips, you can tackle common issues and keep your home comfortable. By identifying the problem, maintaining clean filters and coils, checking the thermostat, clearing the condensate drain, and ensuring proper airflow, you can keep your AC unit running efficiently and effectively. Regular maintenance not only prolongs the life of your AC unit but also helps prevent future breakdowns, saving you time, money, and discomfort in the long run. Stay cool and comfortable by taking proactive steps to care for your AC system.
