When your air conditioner suddenly stops working—especially during a hot day in Altadena or Pasadena—it can feel like an emergency. Whether your home is heating up fast or your system won’t turn on at all, knowing what to do in those first few minutes can make a big difference.
While some issues require professional repair, there are a few safe steps you can take before help arrives.
In this guide, we’ll walk you through what to do during an AC emergency, what to avoid, and when to call All American HVAC at 626.736.0962 for immediate service.
🚨 Step 1: Check Your Thermostat
It may sound simple, but thermostat issues are one of the most common causes of sudden AC problems.
What to check:
- Is it set to “cool” mode?
- Is the temperature set lower than room temperature?
- Are the batteries working?
Why it matters:
A small setting issue can look like a major system failure.
⚡ Step 2: Check Your Circuit Breaker
If your AC won’t turn on at all, it could be a power issue.
What to do:
- Locate your electrical panel
- Check for a tripped breaker
- Reset it once if needed
⚠️ If it trips again, stop and call a professional—this could indicate a deeper electrical problem.
👉 Call 626.736.0962 for safe, reliable service.
🌬️ Step 3: Inspect Your Air Filter
A clogged filter can restrict airflow so much that your system stops working properly.
Quick fix:
- Remove the filter
- Replace it if it’s dirty
This is one of the fastest ways to restore airflow in your home.
🧊 Step 4: Look for Ice on the Unit
If you notice ice on your indoor or outdoor unit, your system may be frozen.
What to do:
- Turn off your AC immediately
- Allow the system to thaw
Why this matters:
Running a frozen system can cause serious damage.
👉 If ice keeps forming, call All American HVAC at 626.736.0962.
🌿 Step 5: Check the Outdoor Unit
Your condenser (outside unit) needs proper airflow to function.
Look for:
- Debris, leaves, or dirt buildup
- Blocked airflow around the unit
Quick fix:
Clear at least 2 feet of space around the unit if possible.
⚠️ What NOT to Do During an AC Emergency
Avoid making the problem worse by steering clear of these:
- ❌ Don’t keep restarting your system repeatedly
- ❌ Don’t attempt electrical repairs yourself
- ❌ Don’t ignore unusual noises or smells
- ❌ Don’t run the system if it’s frozen
When in doubt, it’s always safer to call a professional.
