🔍 Why Is My AC Blowing Hot Air?
If your AC is blowing warm air instead of cold, don’t panic — many causes are easy to fix or diagnose. Some you can handle today before calling a pro.
✅ Clogged Air Filter
A dirty filter blocks airflow, overheats your system, and stops it from cooling. Check yours first. Learn the proper filter direction in our Furnace Filter Direction Guide.
✅ Frozen or Dirty Coils
Dirty coils stop heat transfer, freezing your system. Keep coils clean and schedule annual maintenance. See tips in our Ultimate HVAC Guide.
✅ Bad AC Capacitor
A failing capacitor stops your AC from starting or keeps it blowing warm. This part must be replaced by a licensed pro.
✅ Low Refrigerant
If your system is low on refrigerant, it can’t cool. Signs include ice on lines, bubbling noise, or long run times. Call a licensed tech — handling refrigerant requires certification.
✅ Thermostat Issues
Double-check your thermostat settings. Sometimes fan-only mode or dead batteries can stop your AC from cooling.
🔎 Fixy’s Tips: Common Questions & Fixes
How often should I change my filter?
Most homes need a new filter every 1-3 months. Pets, allergies, or construction may mean more frequent swaps.
Can dirty coils make my AC blow hot?
Yes — dirty coils block heat exchange. Annual coil cleaning helps prevent breakdowns and high energy bills.
Could a bad thermostat be the cause?
It’s possible. Try fresh batteries and double-check your settings.
Is it worth upgrading to a smart thermostat?
Absolutely. Smart thermostats help lower bills and let you monitor temps when away. See our HVAC Services for pro installation.
