• Dirty Air Filter
  Your air conditioner may struggle to chill your area if your air filter is unclean since it might hinder airflow. The air filter’s job is to prevent dust, dirt, and other debris from getting into your AC unit. When the filter becomes clogged, it cannot do its job correctly, reducing the airflow to the AC unit. Check and replace the air filter regularly, usually every 30-60 days.
  
  
• Thermostat Problems
  The thermostat controls your AC unit’s temperature and settings. It may not be functioning correctly or might be set incorrectly. Ensure that the thermostat is set to the right temperature and is working correctly. If you have a programmable thermostat, make sure it’s programmed correctly.
  
  
• Dirty Condenser Coils
  The condenser coils on the outdoor unit can become dirty, limiting the transfer of heat. Dirt, debris, and other outdoor elements can accumulate on the coils over time, preventing them from properly releasing the heat your AC unit removes from your home. Clean the coils regularly to allow proper heat transfer. You can use a garden hose to gently wash away dirt and debris.
  
  
• Low Refrigerant Levels
  The refrigerant is a crucial component of your AC unit. Your home’s internal heat is absorbed by it, and it radiates it outdoors. Your air conditioner may work harder and be less effective if there are low refrigerant levels. Common causes of low refrigerant levels include leaks, faulty valves, and loose connections. In this case, call our HVAC professional to recharge your unit.
  
  
• Faulty Compressor
  Your air conditioner’s compressor is the brain of the entire system. It pumps refrigerant through the system, allowing your AC unit to cool your space. A faulty compressor can prevent your AC unit from cooling your space effectively. Symptoms of a faulty compressor include strange sounds, warm air coming from the AC unit, and increased energy bills. A professional technician can diagnose and repair the issue.
  
  
• Blocked Air Ducts
  The air ducts are responsible for distributing cool air throughout your space. Blocked air ducts can limit airflow, making it difficult for your AC unit to cool your space. Dust, dirt, and other debris can accumulate in the ducts over time, blocking the airflow. Clean the air ducts or contact our professional HVAC technician to have them cleaned thoroughly.
  
  
• Leaking Ductwork
  Leaking ductwork can reduce airflow, causing your AC unit to work harder than necessary. It can also result in hot air getting into your space, making it difficult for your AC unit to cool space. Get in touch with our professional to have your ductwork inspected and repaired.
  
  
• Oversized or undersized AC unit
  If your AC unit is too big or too small for your space, it won’t be able to cool your space efficiently. An oversized unit will cool your space quickly but will not dehumidify it properly, resulting in a damp feeling. An undersized unit will struggle to cool your space and will run continuously, leading to increased energy bills.

Consult our HVAC professional to determine the appropriate size for your space. In conclusion, several factors can cause your AC unit to fail to cool your space. Regular maintenance and inspections by a professional HVAC technician can help identify and fix these issues before they become significant problems.
