If your HVAC in Lenoir City, TN, isn’t keeping your home or rental property cool, you’re not alone. Many homeowners and property managers face this issue, especially during peak summer. Fortunately, there are several common reasons why your HVAC system might not be working efficiently—and most of them have simple solutions.
Check Your Thermostat Settings
Before assuming the worst, verify that your thermostat is set correctly. Ensure it’s on “cool” mode and the temperature is set lower than the current room temperature. Also, check if the fan setting is on “auto” rather than “on,” as the latter can cause the system to blow air continuously without actually cooling.
Inspect and Change the Air Filter
A clogged air filter can significantly reduce your
HVAC system’s efficiency. Dirty filters restrict airflow, making it harder for your system to cool your home. Replace the filter every 1–3 months to keep your system running smoothly.
Look for Refrigerant Leaks
Low refrigerant levels can prevent your HVAC in Lenoir City, TN, from cooling effectively. Signs of a refrigerant leak include warm air blowing from vents, hissing sounds near the unit, or ice buildup on the refrigerant lines. If you suspect a leak, contact a professional immediately.
Check for Dirty Condenser Coils
Your outdoor condenser unit disperses heat from your home. The coils won't function properly if they are covered in dirt and debris. Regularly clean the condenser coils with a gentle spray of water to improve cooling performance.
Inspect the Ductwork for Leaks
Leaks in your ductwork can cause
cool air to escape before it reaches your living space. Look for visible gaps or disconnected ducts in your attic or crawl space. Sealing these leaks with HVAC tape can help improve airflow.
Test the Capacitor and Compressor
If your system isn’t cooling at all, the issue could be with the compressor or capacitor. A failing capacitor may cause the system to struggle when starting, while a faulty compressor can prevent cooling altogether. These components require professional inspection and repair.
Ensure Proper Airflow Around the Outdoor Unit
Your outdoor unit needs sufficient airflow to function efficiently. Keep at least two feet of clearance around the unit by removing debris, overgrown plants, and other obstructions. Additionally, ensure the area around is free from dirt and dust buildup, as these can restrict proper air circulation. A clogged or blocked condenser unit can cause your HVAC in Lenoir City, TN, to overheat and work inefficiently. If you notice the system running but not cooling, check for nearby obstacles that could be disrupting the airflow. Keeping the outdoor unit well-maintained will improve performance and extend the lifespan of your HVAC system.
