Is your air conditioner suddenly giving you the cold shoulder (or rather, no cold air at all)? Don't sweat it! Let's walk through why your AC might have stopped working and what you can do about it right now. My name is Luke Barbosa. I am the owner of Heat and Air Gurus based out of Carrollton, TX. I hope this blog helps you more than the blogs written by marketing companies!
Common Reasons Your AC Stopped Working Suddenly
1. The Simple Stuff First
Before panicking, check these quick fixes when your AC isn't working:
Is your thermostat on and set correctly?
Did a circuit breaker trip?
Is your filter so dirty it's choking your system?
2. The Not-So-Simple Problems
If your AC unit stopped working after these checks, you might be dealing with:
Frozen evaporator coil (yes, freezing happens even in Texas heat!)
Low refrigerant from a leak
Failed capacitor (super common in our hot DFW summers)
Condensation Safety tripped (see if water is in the pan or dripping on side of home)
Furnace Stopped Working!
Did you know your furnace has the fan inside of it which blows out the air for the Air Conditioner? Meaning part of your furnace actually works year around.
The following could help you restore your comfort when your furnace decides to quit during a cold snap or hot summer day. Here's your game plan:
Quick Furnace Fixes
1. Check your thermostat batteries
3. Look for a blocked air filter
4. Check if your pilot light is out
5. Check to make sure the furnace switch is on
PRO TIP: Sometimes cable guys or pest control may mistake your furnace power switch for the light switch. This will cause both your AC and furnace to stop working. Be sure to check this simple step before calling an HVAC pro.
When to Call a Pro
Your furnace needs immediate attention if you notice:
Strange noises (banging, whistling, humming or grinding)
Yellow pilot light instead of blue
Unusual smells (especially gas odors and burnt electrical smells)

When your AC or furnace stops working, here's how to stay comfortable:
