Why Is My AC Blowing Hot Air?

As the summer months approach, there's nothing worse than feeling the hot, stuffy air inside your home or office. If you're experiencing this, you might wonder, "Why is my air conditioner blowing hot air?" There are several reasons why this might be happening, and at Zion Custom Air, an HVAC company, we explore some of the common causes and solutions.

Thermostat

One of the most common reasons your air conditioner may be blowing hot air is an issue with your thermostat. The thermostat is the device that controls the temperature in your home or office. If it's not set correctly or is malfunctioning, it can cause your air conditioner to blow hot air. Sometimes, the thermostat might be set to "heat" instead of "cool." Double-check your thermostat and set it to the correct temperature and mode.

Refrigerant

Another common cause of an air conditioner blowing hot air is low refrigerant levels. Refrigerant is a chemical used in your air conditioner to cool the air. If the refrigerant levels are low, it can cause your air conditioner to blow hot air. This issue requires a professional technician to fix, as adding refrigerant to your air conditioner is a delicate process. A qualified technician will be able to diagnose the issue and add the correct amount of refrigerant to your system.

Dirty Air Filters

Dirty air filters are another reason your air conditioner may blow hot air. Air filters are essential to your air conditioning system, as they help keep the air clean and flowing freely. Over time, air filters can become clogged with dirt, dust, and other debris, restricting airflow through your system. When this happens, your air conditioner may be unable to cool the air properly, causing it to blow hot air. You should change your air filters every three months to ensure your system is running smoothly.

Frozen AC Coil

If your air conditioner is blowing hot air and you notice ice buildup on the unit or the air vents, this may indicate that your AC coil is frozen. AC coils are responsible for absorbing the heat from the air and releasing it outside. When the coils freeze, it can cause the air to blow hot. Several factors, including low refrigerant levels, dirty air filters, or a malfunctioning blower motor, can cause frozen coils. It's essential to address this issue promptly, as frozen coils can cause significant damage to your air conditioning system.
