Why Is Your Home Air Conditioner Blowing Hot Air?

As the temperatures rise during the hot summer months, there’s nothing more frustrating than discovering that your air conditioner is blowing hot air. This can be particularly frustrating if you’ve invested in a high-quality HVAC system. If you’re experiencing this problem, you’re not alone. Many homeowners struggle with air conditioning systems that suddenly blow hot air, making them uncomfortable and unsure of what to do next. If you require professional help, call All Star Heating & Air if you need any assistance in AC repair services in Summerville and surrounding areas.

There are several reasons your AC may be blowing hot air and solutions to help you get it back up and running as it should.

• Clogged Air Filters:
  The air filter is one of the essential components of your air conditioning system. It’s responsible for trapping dirt, dust, and other contaminants before they enter your home, ensuring that the air you breathe is clean and healthy. However, if your air filter becomes clogged with dirt and debris, it can restrict airflow and cause your air conditioner to blow hot air. This is a common problem, particularly in homes with pets or those located in dusty areas. Fortunately, it’s also an easy problem to solve. Replace your air filter regularly, ideally every one to three months, or more often if you have pets or allergies.
• Dirty Condenser Coils:
  Your air conditioner’s condenser coils are crucial in cooling, absorbing heat inside your home, and releasing it outside. However, if the condenser coils become dirty or clogged with debris, they can’t function effectively, which can cause your air conditioner to blow hot air. This is another common problem, particularly in homes where the outdoor unit is exposed to leaves, grass, and other outdoor debris. The solution is to have your condenser coils professionally cleaned at least once a year, preferably before the start of the cooling season.
• Low Refrigerant Levels:
  Refrigerant is the chemical that cools the air in your air conditioning system. You may have low refrigerant levels if your air conditioner blows hot air. This can be caused by a refrigerant leak or normal wear and tear over time. Unfortunately, fixing a refrigerant leak is not a DIY project and should be handled by a licensed HVAC technician. If you suspect your air conditioner is low on refrigerant, contact All Star Heating & Air immediately to schedule an appointment for a professional evaluation.
• Faulty Thermostat:
  The thermostat is the control center of your air conditioning system, responsible for regulating the temperature in your home. If your thermostat is faulty or malfunctioning, it can cause your air conditioner to blow hot air. This is often an easy problem to solve. First, ensure your thermostat is set to “cool” mode and the temperature is lower than the current room temperature. If that doesn’t work, check the batteries in your thermostat and replace them if necessary. If you still have issues, it may be time to upgrade to a newer, more efficient thermostat.
• Electrical Issues:
  Your air conditioning system relies on a complex network of electrical components to function properly. If any of these components become damaged or malfunction, it can cause your air conditioner to blow hot air. This can be a dangerous problem, so we suggest contacting our licensed HVAC technician immediately if you suspect you’re experiencing electrical issues. All-Star Heating & Air can thoroughly evaluate your electrical system to identify and resolve any issues.

If your home air conditioner is blowing hot air, it’s essential to act quickly to resolve the issue. Not only is it uncomfortable to live in a hot and stuffy house, but it can also lead to more severe problems, such as poor indoor air quality and mold growth.
