Why Is My Air Conditioner Blowing Hot Air?

If your air conditioner is producing warm air instead of cool, several potential problems could be the culprit.

Thermostat Issues:

  • Verify that your thermostat is set to "cool" and the desired temperature is lower than the current room temperature.
  • If the thermostat is accidentally set to "heat" or "fan only," the AC won't function as intended.

Air Filter Problems:

  • A dirty or clogged air filter restricts airflow, hindering the AC's cooling ability.
  • Regularly replacing or cleaning the air filter is essential for optimal performance.

Refrigerant Concerns:

  • Refrigerant is crucial for the cooling process. A leak in the system can cause reduced cooling efficiency and warm air output.

Compressor Malfunction:

  • The compressor is a vital component responsible for the AC's cooling cycle. If it's damaged or failing, it can lead to warm air.

Electrical Problems:

  • Electrical issues such as tripped breakers or blown fuses can disrupt the AC's operation.

Condenser Unit Issues:

  • The outdoor condenser unit requires regular maintenance. Blockages, dirt buildup, or malfunctions can impede cooling.

Evaporator Coil Problems:

  • Frozen evaporator coils prevent heat absorption, resulting in warm air. This can be caused by low refrigerant, poor airflow, or other underlying issues.

Ductwork Issues:

  • Leaks or holes in the ductwork can allow warm air to infiltrate the cooled air, reducing overall cooling efficiency.

If you're unable to identify or resolve the issue, it's recommended to contact an HVAC professional for diagnosis and repair.

Common Symptoms of Broken Air Conditioners

A broken air conditioner is a major inconvenience. Whether you have a central unit or a ductless system, many parts and components can wear out or break. At Comfort Energy, Inc., our Milpitas AC repair specialists will thoroughly inspect your unit and determine what needs to be done in order to get it back up and running efficiently for years to come. While it may be difficult for someone untrained to determine exactly what’s wrong with their unit, it’s helpful to know common symptoms that your air conditioner is not working as it should.

Common AC Problems in Milpitas Homes


  • Your unit makes strange noises: If you hear a wailing, grinding, squealing, or grating sound, you can rest easy knowing that it’s not a poltergeist. Rather, it’s your air conditioner. Anytime your blower motor malfunctions or something is caught in it, it will cause your system to make these odd noises. The longer you go without AC repairs, the louder these noises will get until they’re hard to ignore. Anytime you hear your unit making any odd noises, it’s important that you call us right away. The sooner repairs are done, the more you will protect your unit from being completely destroyed.
  • Your unit doesn’t produce cool air from the vents when it’s turned on, it cannot meet the temperature you set on the thermostat, or air is only coming from limited vents: Unfortunately, there are many possible causes for such issues. One reason that we tend to see a lot is improperly sized units. If your unit is not large enough to compete with your property’s cooling demands, it will not be able to meet the temperature you set. When we arrive at your property, we will use state-of-the-art tools to perform an inspection and get to the bottom of the matter.
  • Your unit has frozen coils: Can you remember the last time you had your air filters changed? If you cannot, then it probably is the reason for your frozen coils. However, this isn’t the only cause of this issue. It could also be a result of leaking refrigerant.
  • Your unit is leaking water from ducts or vents: This is an urgent matter that needs to be handled right away. Not only does a leak prevent your unit from functioning and keeping you cool, but the excess moisture creates the perfect breeding ground for mold and mildew. Not only that, the longer your unit continues to leak, the more your property is susceptible to water damage.

AC Running But Not Cooling? Here's Why

If your air conditioner is running but not cooling, there could be a few different causes.

First, you should check to see if the thermostat is set correctly and that it’s not set to ‘heat’ or ‘off’.

You should also check the air filter. A clogged or dirty filter will reduce airflow and make your AC less efficient at cooling. If the filter looks dirty, replace it with a clean one.

Another possible reason for an AC running but not cooling is if the unit has frozen up due to a lack of airflow. In this case, you should turn off the power to the AC unit and let it thaw out so that melted ice can be properly drained out, and see if it’s a one-time problem.

If these steps don’t help solve your problem then you may need to call in an HVAC technician as they are trained to diagnose and repair more complex AC system issues like low refrigerant levels or other mechanical problems which can prevent your system from operating properly.

Regardless of the issue you’re having, it’s important that you call us for repairs right away. Left alone, these symptoms will get worse until it’s no longer possible to repair your system and a replacement will be necessary.
