Top 10 Signs Your A/C Unit Needs A Check Up

On a hot day, the guy cools with his head in the refrigerator. Broken air conditioner.

Is your air conditioning unit struggling to keep you cool? Don’t wait until it’s too late! Here are the top 10 signs that indicate your A/C unit needs a check-up, along with expert tips on how to fix it and stay cool all summer long.

  1. Weak Airflow: If you notice weak or insufficient airflow coming from your vents, it could indicate a problem with your A/C unit’s compressor or ductwork. Check for blockages and clean or replace air filters if necessary.
  2. Warm Air: Feeling warm air instead of cool air coming from your vents is a clear sign that your A/C unit is not functioning properly. Check the thermostat settings and ensure that the unit is set to “cool.”
  3. Strange Noises: Unusual noises such as banging, grinding, or squealing coming from your A/C unit could indicate various issues, including loose components, worn-out belts, or motor problems. Schedule a professional inspection to diagnose and fix the problem.
  4. Frequent Cycling: If your A/C unit is turning on and off frequently, known as short cycling, it could be a sign of an oversized unit, a malfunctioning thermostat, or refrigerant leaks. Contact a professional HVAC technician to assess and repair the issue.
  5. High Humidity: Excessive indoor humidity levels despite your A/C running could indicate a problem with the unit’s dehumidification capabilities. Have a technician check the evaporator coil and drainage system for any issues.
  6. Unpleasant Odors: Foul or musty odors emanating from your vents indicate mold or mildew growth within your A/C system. Clean or replace air filters and schedule a professional duct cleaning to eliminate the source of the odor.
  7. Leaking Refrigerant: If you notice refrigerant leaks around your A/C unit or ice buildup on the refrigerant lines, it’s crucial to address the issue promptly to prevent further damage to your system. Contact a certified technician to locate and repair the leaks.
  8. Increased Energy Bills: A sudden spike in your energy bills without a corresponding increase in usage could indicate that your A/C unit is working harder than necessary due to underlying issues. Schedule a maintenance check-up to improve efficiency and lower your energy costs.
  9. Uneven Cooling: If certain areas of your home are consistently warmer or cooler than others, it could indicate airflow problems or issues with your A/C unit’s capacity. Have a professional assess your ductwork and system to ensure even distribution of cool air.
  10. Age of the Unit: Finally, if your A/C unit is more than 10-15 years old, it may be nearing the end of its lifespan and could require frequent repairs or replacement. Consider investing in a new, energy-efficient unit to improve comfort and reduce operating costs.
