Why Is My AC Not Blowing Cold Air?

July 8, 2022

Let us help solve why your air conditioner is blowing warm air!

In the Los Angeles heat, air conditioning is a must. An air conditioning breakdown is a nightmare in the summer due to comfort levels for you and your family. Like the saying goes, you don’t know what you have until it’s gone. This rings true for air conditioning, because you never realize how much you rely on it until it breaks down or needs a repair in the summer. Your AC blowing warm air is just as uncomfortable as a broken air conditioner. If you notice your air conditioner is not blowing cold air, it could be due to a variety of factors. In this article, we will explain why your AC may not be blowing cold air and what to do to get you cool and comfortable once again!

While some reasons as to why your air conditioner is blowing cold air could be a simple fix, others require the help of an expert. When in doubt, we recommend always contacting a professional to ensure your safety and comfort. Below we have listed reasons as to why your AC is not blowing cold air and how to proceed.

Loss of Power

Your air conditioner uses a large amount of power to produce cool air. An air conditioner losing power can be due to an overloaded circut or whole home power loss. If your breaker trips or a fuse is blown, this could result in your air conditioner blowing warm air. Try safely resetting your breaker, but don’t go hunting for cut or loose wires.

Thermostat Issue

Once power loss has been checked, make sure your thermostat is properly working. First, ensure the thermostat settings have not been altered. Your thermostat should be set to “cool” or “auto” and read your desired temperature under the setting. If everything is properly set, try changing the batteries if it is battery operated. A communication issue between the thermostat and unit could be the problem, which requires professional help.

Blocked Compressor

If your air conditioner is not blowing cold air, it could be due to your outdoor unit. Debris such as grass clippings, branches, and leaves can harm your air conditioner’s efficiency and air flow, which results in warm air. Make sure your unit is clear and able to breathe easy, so you can do the same!

Refrigerant Leak

The refrigerant plays an important role in your air conditioner’s ability to function and could be the cause of your AC blowing warm air. Your refrigerant is likely leaking, but your air conditioner will continue to run and blow warm air. Your air conditioner is likely overworking itself, which can result in further problems and a high utility bill. If this is the case, give us a call to find the leak and get your home comfortable again!

Dirty Air Filter

Your air filter can be an indicator of many problems you may be experiencing, and blowing warm air is one of them. A dirty or clogged air filter harms your unit’s ability to push air through. While struggling to maintain airflow, your unit is working harder and using more energy. Your unit can shut down from overworking itself, so be sure to keep a clean air filter!

Clogged Drain Line

Your air conditioner cools and decreases humidity throughout your house. The water it pulls from the humidity and moisture exits through a drain line. Debris such as dust and dirt can be carried off by the moisture, which causes a build up over time. Excess moisture also causes mold and mildew and adds to the build up. A clog can prevent your air conditioner from blowing cool air or blowing any air in general. Drain line clogs are likely deep and require professional help, but we are happy to help get your drain line unclogged and your air conditioner working in no time.
