Why Your AC Is Blowing Warm Air — And When to Call a Pro

Tickles Heating & Air | Wichita, KS

It’s the middle of summer in Wichita, and your air conditioner is running — but all you’re getting is warm air? That’s not just frustrating — it’s uncomfortable and can even be dangerous when temps climb into the 90s and beyond.

At Tickles Heating & Air, we hear this complaint a lot:

“Why is my AC blowing warm air?”
The good news is, sometimes it’s an easy fix. Other times, you’ll want a professional to take a closer look before a small issue turns into a major repair.

Let’s go over a few common reasons your AC might be acting up — and when it’s time to give us a call.

1. Double-Check Your Thermostat

Before diving into bigger concerns, take a quick look at your thermostat. Is it set to “cool” and not just “fan”? Is the temperature set lower than the room temperature?

You’d be surprised how often this little detail is the culprit. If everything looks good and your home’s still not cooling down, keep reading.

2. Dirty or Clogged Air Filter

One of the most common causes of weak or warm airflow is a dirty air filter. When your filter gets clogged, it restricts airflow and makes it harder for your system to push out cool air.

If it’s been a few months since your last filter change, try swapping it out. It’s an easy, inexpensive fix that can make a big difference — especially during the hot Kansas summer.

3. Low Refrigerant (Or a Leak)

If your AC is low on refrigerant, or if there’s a leak, it won’t be able to cool properly — no matter how long it runs. You might notice warm air blowing, ice on your unit, or a hissing sound.

This isn’t something you can handle on your own. Refrigerant work requires a licensed HVAC technician, and in some cases, a leak might signal it’s time to talk about long-term solutions.

4. Frozen Coils

When your AC’s coils freeze up — often due to poor airflow or refrigerant issues — your system may still blow air, but it won’t be cold. If you suspect frozen coils, turn the system off and call a professional before things get worse.

5. Compressor or Electrical Issues

More complex problems, like a bad compressor or electrical failure, can also lead to your AC blowing warm air. These are issues that need expert diagnosis and repair, so don’t try to DIY them.
