If your AC won’t turn on during a Texas heatwave, Apple AC & Heat Services in Rockwall, TX is here with expert tips and emergency service to help you stay safe and cool—fast.
Nothing is more stressful than a failing air conditioner during a brutal Rockwall heatwave. When your system suddenly won’t turn on, your home heats up fast, putting your comfort—and in some cases, your health—at risk. While it may feel like an emergency, some AC issues can be fixed with a quick check. Others require immediate professional repair. Either way, you don’t have to sweat it out alone.
Here’s exactly what to do when your AC won’t turn on, how to troubleshoot it safely, and when to call Apple AC & Heat Services for urgent help.
Check the Thermostat First
Before assuming the worst, inspect your thermostat. It may seem basic, but dead batteries, incorrect settings, or power issues are common causes of AC failure.
- Make sure it’s set to “cool”, not “off” or “heat”
- Lower the temperature to 68–70°F to trigger the system
- Replace batteries if the screen is blank or unresponsive
If the display isn’t lighting up or the system still doesn’t kick on, you may have a wiring or power issue that needs professional attention.
Inspect the Circuit Breaker
Your AC system pulls a lot of power, especially in extreme heat. During a heatwave, it’s not uncommon for circuit breakers to trip. Check your breaker panel and look for the switch labeled “AC” or “HVAC.”
- If it’s in the middle or “off” position, reset it by turning it fully off, then back on
- If it trips again right away, do not continue resetting—this signals a deeper electrical issue
Never force a system to run after a breaker trip. This can cause further damage or even fire hazards.
Look at the Outdoor Unit
The outdoor condenser unit should be running when your AC is cooling. If it’s completely silent or appears off:
- Ensure the disconnect box outside (usually near the unit) is in the “on” position
- Check for visible damage, debris, or signs of burning
- Listen for humming, buzzing, or clicking—these noises can indicate a failing capacitor or compressor
If you’re unsure, it’s best to leave the unit alone and call for help. Attempting to open or fix a high-voltage system without proper tools is dangerous.
Check the Air Filter and Drain Line
A clogged air filter can restrict airflow so severely that it causes the system to shut down to protect itself. Likewise, a blocked condensate drain line may trigger a float switch that disables your AC to prevent water damage.
- Replace your air filter if it looks dirty or hasn’t been changed in 1–3 months
- Check for water near your indoor unit or unusual moisture near vents
These are two of the most preventable causes of AC shutdown—and two of the easiest to fix.
If Nothing Works, Call the Pros—Fast
When the basics don’t bring your AC back to life, it’s time to bring in a professional. You could be dealing with:
