Why Is My AC Blowing Warm Air?

Posted on

Woman fanning herselfWhen you run your air conditioner, you expect it to cool your home and do it fast. Sometimes, however, your system may run into problems that cause it to blow warm air instead. Why does this happen? A variety of issues could be causing the problem.

In this blog, we’ll discuss some of the most common reasons an AC unit might blow warm air and fail to cool your home.

Causes of AC Temperature Issues

Many problems can plague an air conditioner after years of wear and tear. Even new systems can run into problems on occasion. Some common reasons why an AC unit might blow warm air include:

  • Dirty evaporator coils and air filters: The evaporator coils need to stay clean with the help of an air filter. When these coils get dusty or covered in dirt, they won’t function as they should.
  • Dirty outdoor air condenser: The outdoor part of your AC unit needs a free flow of air in order to cool your home. Dirt, mud, and other debris can clog up the airways and lead to warm air coming from your vents.
  • Thermostat issues: Your thermostat is the only way to tell your AC what to do. If the electrical signals aren’t hitting the AC unit, you can’t cool your home.
  • Low refrigerant level: Every AC unit has coolant liquid that flows through pipes to cool the air. If this liquid leaks out or dries up, your AC unit can only push through the air it received from outside.
  • Electrical panel issues: Your AC unit takes a lot of electricity to operate. When there isn’t enough power for it, or your system blows a fuse, the unit just won’t run.

These problems and others can cause your air conditioner to blow warm air. Most of these issues need to be diagnosed and solved by a professional. With an expert on the job, you can rest easy knowing the problem will be resolved correctly.

DIY AC Maintenance Check

If you’re unsure why your air conditioner is blowing warm air, there are a few things you can look at that might help. Consider these options to see if you have a simple fix on your hands:

  • Replace your air filter: Air filters are essential to helping your AC run well. If you haven’t replaced your air filter in a few months, it may be time for a new one.
  • Check your outdoor unit: If your outdoor unit is caked in mud or dirt, carefully brush it away. This allows for better airflow into the unit and into your home.
  • Listen for odd noises: Your AC has many moving parts, and if you listen closely, you may hear a fan or motor that’s failing. Once you know where the issue is, you can call an HVAC technician who can fix the problem easily.

Always be careful when working closely with your air conditioner. Some problems are easy to fix, while others require a professional.
