Why Is My AC Running But Not Cooling?

As the summer sun beats down, the key to a cool and comfortable home is your central air conditioning system. But what happens when your air conditioner is humming away yet fails to deliver that sweet, refreshing cold air? It’s a frustrating scenario, and there are several reasons why your AC unit might be running without cooling. Advantage Heating & Air Conditioning is here to diagnose the culprit and get your home comfortable again.

What Causes Air Conditioners to Run But Not Cool?

There are several common reasons why air conditioning systems might run without blowing cold air effectively. Let’s explore some of the most frequent culprits:

  • Thermostat Issues: The most common reason is often the simplest to fix. Check your thermostat settings! Ensure it’s on “cool” mode and set to a temperature lower than the current room temperature. Some thermostats offer fan-only options that keep indoor air circulating without the air conditioner running, which results in warm air coming from your vents. Double-check the fan setting is set to “auto” or “on.”
  • Dirty Air Filter: Your system’s air filter traps dust and debris before they enter the AC unit. A clogged filter restricts airflow, hindering the central air conditioning system and its ability to absorb heat and cool your home. Replacing air filters regularly (every one to three months during peak cooling season) is crucial for proper airflow, optimal performance, and reliable cool air.
  • Frozen Evaporator Coil: This might sound counterintuitive, but a frozen evaporator coil can prevent cold air from blowing from the air conditioner. It can occur due to restricted airflow from a dirty filter, low refrigerant levels, or a malfunctioning fan motor. A frozen coil requires professional attention to prevent damage to the AC system.
  • Blocked Condenser Coil: Located in your outdoor condenser unit, the condenser coil releases heat extracted from your home. Dirt, leaves, and debris can accumulate on the coil, reducing its ability to dissipate heat. Regularly clear debris around the outdoor unit and ensure proper airflow. If the coil in the outdoor unit is heavily clogged, a professional cleaning might be necessary to restore cool air.
  • Low Refrigerant Levels: Refrigerant acts as the lifeblood of your AC system, absorbing heat indoors and releasing it outdoors. Low refrigerant levels can significantly impact cooling efficiency. Repairing a refrigerant leak and adding refrigerant is a job for a certified technician, as improper handling can damage the system.
  • Duct Leaks: Leaky air ducts in your attic, crawl space, or walls can allow cool conditioned air to escape before reaching your living areas. This forces your central air conditioner to work harder to cool your home while also allowing warm indoor air from the attic or crawl space to seep into your living space, negating the cooling effect and resulting in room-temperature air while your AC unit runs.

These are just a few of the reasons commonly behind an air conditioner running but blowing warm air. If you’ve checked for a dirty air filter and debris around your air conditioner yet your AC is still struggling, don’t hesitate to call us for further diagnosis and repair.
