In the Florida Panhandle, where the summer sun doesn’t quit, an AC blowing warm air is a homeowner’s nightmare. If your home feels more like a sauna than a place to cool off, no need to have a total meltdown (yet). This issue is more common than you think, and in many cases, the fix is easier than you’d expect.
At Pros Heating & Air Conditioning, we provide prompt, dependable AC repair services for homeowners throughout South Walton and Okaloosa Counties.
If your AC is blowing warm air, here’s what might be causing it, a few quick fixes to try, and when it’s best to call the Pros.
1. Incorrect Thermostat Settings
Why It Happens: Sometimes, your AC unit isn’t the problem. Instead, the thermostat might be set incorrectly or have a tech glitch. This is one of the simplest things to check first.
Quick Fix:
- Make sure it’s set to “Cool”, not just “Fan” or “Heat.”
- Lower the thermostat a few degrees below the room temperature
- Check and replace batteries if the screen is blank or unresponsive.
Pro Tip: If you’re using a smart thermostat, double-check Wi-Fi settings or recent updates that could have changed the mode.
Call the Pros if: The thermostat is unresponsive or changing settings doesn’t help.
2. Dirty or Clogged Air Filter
Why It Happens: A clogged air filter restricts airflow, causing your HVAC system to overheat and push out warm air instead of cool.
Quick Fix:
- Find your filter (usually behind a return vent or inside your air handler).
- If it’s dusty, gray, or thick with buildup, swap it out!
- Change filters every 30–90 days, especially in Florida’s humid climate.
Avoid This: Don’t run your AC without a filter— it protects your system and indoor air quality.
Call the Pros if: The new filter doesn’t help, or the airflow still feels weak.
3. Low Refrigerant Levels
Why It Happens: Refrigerant is what your AC uses to absorb heat. Low levels mean your air conditioning system might still run, but it won’t cool effectively.
What to Look For:
- AC blowing warm air even when set to “Cool”
- Hissing or bubbling noises near the outdoor unit
- Ice buildup on refrigerant lines
DIY Fix? Unfortunately, this one’s not DIY-friendly. Low refrigerant typically means there’s a refrigerant leak that needs professional repair.
Call the Pros if: You suspect a leak or hear odd noises from the outdoor unit. Our licensed technicians will safely repair leaks and recharge the refrigerant so your cool air returns fast.
4. Electrical or Compressor Issues
Why It Happens: If your indoor fan is blowing but your outdoor condenser unit isn’t running, you might be dealing with an electrical issue or compressor failure.
Quick Fix:
- Check your breaker box for a tripped switch
- Flip the AC breaker off, wait 30 seconds, and turn it back on
- Listen for the outdoor unit to power on
Call the Pros If: The breaker keeps tripping, the outdoor unit stays silent, or the compressor is overheating.
