There’s nothing worse than coming home on a sweltering summer afternoon only to find that your air conditioner has stopped working. When your AC suddenly quits on the hottest day of the year, panic can set in fast. But before you start sweating it out, know that there are a few steps you can take to troubleshoot the problem—and that Jon Wayne Heating & Air is always here with emergency services if things don’t cool down quickly.
In this guide, we’ll walk you through what to do if your AC fails, from quick checks you can try yourself to when it’s time to call in the professionals.
Step 1: Stay Calm and Check the Thermostat
When the AC stops running, your thermostat is the first place to look. It might sound simple, but many emergency calls are solved with an easy thermostat adjustment.
-
Confirm settings: Make sure the thermostat is set to “cool” and that the temperature is lower than the current room temperature.
-
Check batteries: If your thermostat uses batteries, they may need to be replaced. Weak batteries can prevent your AC from responding.
-
Reset if needed: Sometimes, restarting the thermostat can resolve temporary glitches.
A quick thermostat check could save you from unnecessary discomfort and repair bills.
Step 2: Inspect the Circuit Breaker
If your AC isn’t turning on at all, a tripped breaker could be the culprit.
-
Locate your electrical panel and check the breaker connected to the air conditioning system.
-
If it’s tripped, flip it fully off, then back on.
-
If it keeps tripping, don’t force it—this could signal a larger electrical issue that needs professional attention.
Restoring power may be all it takes to get cool air flowing again.
Step 3: Check Your Air Filter
Believe it or not, a clogged air filter can cause your AC to stop working properly—or shut down altogether.
-
Look for dirt and dust buildup. A filter that’s caked with debris can block airflow and cause the system to overheat.
-
Replace or clean it. If your filter looks dirty, change it immediately. Most homeowners should replace filters every 1–3 months, especially during heavy summer use.
-
Future prevention. Mark your calendar or set a reminder to change filters regularly to avoid this common cause of AC failure.
A fresh filter can make a huge difference in performance and efficiency.
Step 4: Inspect the Outdoor Unit
Step outside and give your AC’s outdoor condenser unit a quick look.
-
Clear debris: Grass clippings, leaves, and dirt can block airflow. Clear away any buildup around the unit.
-
Check for ice: If you see ice on the coils, turn off the system and let it thaw. Running it while frozen can cause damage.
-
Listen for noises: Strange rattling or grinding sounds may indicate mechanical issues that require a technician’s help.
Keeping the area around your outdoor unit clean can prevent many future problems.
Step 5: Try a System Reset
Sometimes, your AC just needs a fresh start.
-
Turn the thermostat to “off.”
-
Shut off power to the unit at the breaker box.
-
Wait a few minutes, then restore power and turn the thermostat back to “cool.”
If the system kicks back on and runs normally, you may have solved the issue without needing a service call.
