Why Doesn’t My Air Conditioner Blow Cold Air?

Summer can be brutally hot in central New Jersey, and there’s nothing more frustrating than turning on your AC to find it won’t blow cold air to give your family relief.

Is your air conditioner functioning properly? Is it blowing warm air? Learn some of the causes and potential solutions here!

“My AC Is Not Blowing Cold Air” — What Could Be Wrong?

Air conditioner systems not blowing cold air when turned on is a more common problem than you may think. If your air conditioner is not blowing cold air when it should, calling an HVAC technician right away is important to prevent the issue from becoming more serious.

Four common reasons why air conditioners don’t get cold enough are:

  • Dirty air filters: Dirty filters will block airflow, resulting in a lower than normal flow of cool, conditioned air back into your home. Check your air filters and replace them if they appear too dirty. Check out our infographic at the bottom of the page for more cooling tips!
  • Faulty parts: The condenser or compressor could be malfunctioning. The AC condenser works by removing the heat from the air, so a condenser that’s working properly will be blowing warm air outside and returning cool air back inside. The AC compressor is responsible for pushing cold air from the condenser to the vent. If the air blowing from the vent isn’t cold, the compressor may be malfunctioning or misaligned.
  • Electrical issues: Electrical problems can cause your AC to work poorly or not at all. Potential electrical issues include a malfunctioning thermostat, failed sensors, corroded contacts or connectors, broken or shorted wires, and defective breakers. Diagnosing and fixing electrical issues should always be done by a professional.
  • Low refrigerant levels: Low (or empty) refrigerant is a common reason ACs don’t blow cold air. If your system is out of coolant, it can’t remove heat from the air. If refrigerant levels are low, you probably have a leak (refrigerant does not deplete or go bad over time). To permanently fix the problem, the leak must be found and repaired.

It’s important to note that if your air conditioner is older or experienced several problems last season, it may be time for AC replacement.
