What to Do When Your AC Stops Working

A functioning air conditioning system is crucial for comfort, especially during hot weather. When your AC suddenly stops working, it can be both frustrating and uncomfortable. Knowing what steps to take can prevent panic and help restore your cooling system quickly.

Initial Troubleshooting Steps

Check the Thermostat

The first step when your AC stops working is to check the thermostat. Ensure that it is set to the appropriate temperature and mode (cooling mode). Sometimes, a simple bump can change the settings or turn it off accidentally. Make sure it has power and the display is functioning correctly. If the thermostat is battery-operated, replace the batteries and see if this resolves the issue. Also, verify that the thermostat is not exposed to direct sunlight or other heat sources, which can cause false readings.

Inspect the Circuit Breaker

Another critical step is to inspect the circuit breaker. Your AC unit may have tripped the breaker, cutting off power to the system. Locate your electrical panel and look for the breaker labeled for the AC. If it is in the "Off" position or somewhere in between, reset it by flipping it to the "Off" position and then back to "On." If the breaker trips again immediately after resetting, this could indicate a more serious electrical problem and a professional should be contacted to investigate further.

Common AC Problems and DIY Fixes

Dirty Air Filters

One of the most common AC problems is dirty air filters. Over time, air filters can become clogged with dirt, dust, and other particles, restricting airflow and reducing the efficiency of your system. To fix this issue, locate the filter, usually found behind a panel near the return air duct. Remove the old filter and replace it with a new one. Regularly changing the air filter, ideally, every 1-3 months, helps maintain optimum performance and air quality.

Frozen Evaporator Coils

Frozen evaporator coils can also cause your AC to stop working. This typically occurs when there is insufficient airflow over the coils due to a dirty filter or blocked vents. To address this, first, turn off the AC to allow the coils to thaw. Check and replace the air filter if needed. Make sure that all vents are open and unobstructed. If the coils continuously freeze even after these steps, it might indicate a refrigerant leak or another issue that requires professional attention. By identifying and resolving these common issues, you can often restore your AC's functionality without needing extensive repairs. If problems persist, consult with a specialist to avoid further complications.

When to Call a Professional

Strange Noises or Odors

If your AC unit starts making strange noises or emitting unusual odors, it's time to call a professional. Sounds such as grinding, squealing, or banging can indicate serious mechanical issues that require expert intervention. Similarly, foul odors can suggest problems like mold growth within the system or a burnt-out component. Ignoring these signs can lead to further damage and more costly repairs. Consulting our technicians promptly can prevent minor issues from becoming major expenses.

Inconsistent Cooling

Inconsistent cooling is another issue that warrants professional attention. If some areas of your home are significantly cooler than others or your AC unit struggles to maintain the set temperature, there could be a problem with the ductwork, thermostat, or even the refrigerant levels. These issues are typically beyond the realm of DIY fixes and require specialized tools and knowledge. Contacting our professionals ensures that the underlying problem is accurately diagnosed and repaired efficiently.

Preventative Maintenance Tips

Regular Filter Replacement

One of the simplest yet most effective preventative maintenance tips is regular filter replacement. Clean filters ensure optimal airflow and improve indoor air quality. Depending on usage, filters should be replaced every 1-3 months. Set a reminder to check them regularly, especially during peak usage times. This small task can significantly extend the life of your AC unit and enhance its efficiency.

Annual Professional Check-ups

Routine annual check-ups by our professionals are essential for maintaining your AC unit. During these check-ups, our technicians will inspect all components, clean essential parts, and ensure everything is functioning correctly. They can also identify and address potential problems before they turn into costly repairs. Investing in regular professional maintenance helps keep your system running smoothly and extends its lifespan.

By understanding initial troubleshooting steps and common issues, you can often resolve minor problems yourself.
