When summer heat starts bearing down, the last thing you want is for your air conditioner to suddenly stop working. But if you find your AC isn’t turning on, don’t panic—there may be a few simple reasons behind the issue. Before you call in the experts for air conditioning repair in Mobile, AL, there are a handful of safe troubleshooting steps you can take on your own.
At Peaden, we know how important it is to keep your home cool and comfortable. That’s why our trusted HVAC technicians, the Peaden Prosm are here to guide you through the process. While we’re always ready to help, some problems don’t require professional repairs—others, however, definitely do.
Here’s a step-by-step troubleshooting guide to help you decide when it’s time to call in the pros.
Step 1: Check the Thermostat Settings
It might sound obvious, but the thermostat is one of the most common culprits behind an AC that won’t turn on.
- Make sure the thermostat is set to “cool” and the temperature is set lower than the current room temperature.
- If it’s battery-powered, try replacing the batteries.
- Check for a blank screen, which may indicate the thermostat has lost power.
When to Call a Pro: If changing settings or replacing batteries doesn’t bring your system back to life, there may be a wiring or internal issue that a Peaden Pro should inspect.
Step 2: Inspect the Circuit Breaker
Air conditioners require a lot of power, and it’s not unusual for a tripped breaker to shut down the system.
- Find your home’s electrical panel and look for the AC or HVAC breaker.
- If it’s been tripped, flip it fully to the “off” position, then back to “on.”
When to Call a Pro: If the breaker keeps tripping after a reset, don’t continue flipping it—this could signal a serious electrical issue. Contact a Peaden Pro right away.
Step 3: Check the Air Filter
A clogged air filter can restrict airflow to the point where your system overheats and shuts off to protect itself.
- Locate your air filter (usually inside the return vent or at the air handler).
- If it’s visibly dirty or clogged, replace it with a clean one.
When to Call a Pro: If the system doesn’t restart even after installing a fresh filter, there may be an airflow or sensor issue that needs expert attention.
Step 4: Inspect the Outdoor Unit
Sometimes the outdoor condenser unit gets overlooked.
- Check to make sure it has power and is not obstructed by debris or vegetation.
- Listen for any humming or clicking sounds that could indicate the unit is trying to run but can’t.
When to Call a Pro: If the outdoor unit is silent, making strange noises, or appears frozen, stop there and call a Peaden Pro for further diagnosis.
Step 5: Look for a Clogged Drain Line
Many modern AC systems include a float switch that shuts the system down if the condensate drain line is clogged. This prevents water damage, but it can also make your AC appear “dead.”
- Inspect for standing water near the indoor unit.
- If you’re comfortable, try using a wet/dry vacuum on the outside drain line to remove clogs.
When to Call a Pro: If water is leaking or the float switch keeps activating, your system needs professional cleaning and inspection.
