At Copper State Mechanical, we've seen our fair share of AC problems, and we're here to help you identify the cause and find a solution. In this article, we'll explore the possible reasons why your AC is blowing hot air and provide you with tips on how to fix the issue.

Common Causes of Hot Air from Your AC

There are several reasons why your AC might be blowing hot air. Some of the most common causes include:

  • Refrigerant leaks: If your AC is low on refrigerant, it can cause the system to blow hot air. Our Air Conditioning Services team can help you diagnose and repair refrigerant leaks.
  • Dirty air filters: A dirty air filter can restrict airflow and cause your AC to blow hot air. Regular HVAC Maintenance can help prevent this issue.
  • Thermostat issues: A malfunctioning thermostat can cause your AC to blow hot air. If you suspect a thermostat issue, contact our Heating Services team for assistance.

How to Fix the Issue

Once you've identified the cause of the problem, you can start working on a solution. Here are some steps you can take:

  • Check and replace the air filter: Make sure to check and replace your air filter regularly to prevent dirty air filters from causing issues.
  • Inspect and clean the condenser coils: Dirty condenser coils can cause your AC to blow hot air. Our Ductless System Services team can help you inspect and clean the condenser coils.
  • Call a professional: If you're not comfortable DIY-ing the repair or if the issue persists after trying the above steps, it's time to call a professional. Our team at Copper State Mechanical is available to help you with all your AC needs in San Tan Valley, Queen Creek, and surrounding areas.
