Why Is My AC Running But Not Cooling My House?

Dealing with a malfunctioning air conditioning (AC) system can be incredibly frustrating, particularly during the scorching summer months. Over the years, one of the most common questions we get from homeowners is “how do I make my HVAC system more efficient?” While there could be multiple ways, having a well-performing AC unit is a great place to start. If your AC is running but not effectively cooling your house, there could be several underlying issues that require attention.

This comprehensive guide will explore common reasons behind this problem and provide possible solutions to help restore your home’s cooling comfort.

Incorrect Thermostat Settings

The thermostat is the control center of your AC system. Ensure it is set to the cooling mode and the temperature appropriately adjusted. Sometimes, a simple human error or accidental change in settings can lead to inadequate cooling. Switch the thermostat back to the cooling mode and wait for a few minutes to see if cold air starts flowing from the registers.

Dirty or Clogged Air Filters

Air filters are crucial in maintaining optimal airflow in your AC system. Over time, these filters can become dirty or clogged with dust, debris, and pet dander, obstructing proper airflow and reducing cooling efficiency. Regularly clean or replace your air filters to ensure unrestricted airflow and improved cooling performance.

Insufficient Refrigerant Levels or Leaks

Refrigerant is responsible for absorbing heat from the indoor air and cooling it down. If your AC system has insufficient refrigerant levels or leaks, it won’t be able to effectively cool your house. Consult a professional HVAC technician to check for refrigerant leaks, repair any damage, and recharge the system with the appropriate amount of refrigerant.

Malfunctioning Compressor

The compressor is a vital component of your AC system that circulates refrigerant and facilitates heat exchange. A malfunctioning compressor can result in limited cooling. If you suspect compressor issues, it’s best to consult with a professional HVAC technician who can accurately diagnose the problem and perform the necessary repairs.

Inadequate Insulation and Air Leakage

Proper insulation and a well-sealed home are essential for maintaining a cool indoor environment. Poor insulation and air leakage can allow hot air to infiltrate your home and hinder the effectiveness of your AC system. Evaluate your insulation levels and seal any air leaks around windows, doors, and ductwork to minimize heat transfer and maximize cooling efficiency.

Incorrect AC Unit Size

Using the correct AC unit size for your home is crucial. An oversized or undersized unit can lead to cooling problems. Honest Air can assess your home’s specific cooling requirements.
