AC Not Working After Power Outage? Here’s What You Can Do

Experiencing a power outage, followed by your air-conditioning (AC) unit not working correctly, is a stressful and potentially expensive problem. Homeowners can become overwhelmed with the thought of what could be wrong and how to fix it. However, there are steps you can take to investigate the situation and possibly avoid a costly repair bill. In this article, we provide tips on investigating and troubleshooting ACs that were affected by a power outage.

Understanding the Causes of ACs Not Working After Power Outage

There are several possible reasons your air-conditioner may not work after a power outage. A power surge during the power outage is one of the most common causes. A power surge is when there is an increase in power, lasting for a fraction of a second, that can cause electrical damage. Additionally, when the power comes back on, high-voltage electricity may enter and damage the capacitors, circuit boards, and other parts of the AC.

Another potential cause is that the power outage may have caused the AC’s condenser fan to fail, resulting in the refrigerant in the cooling system not properly evaporating and circulating. This can lead to the AC becoming too warm for the thermostat and shutting down as a result.

Troubleshooting Your AC Problem

There are a few measures you can take to troubleshoot an air-conditioner problem caused by a power outage. You should first inspect the unit to determine if there is a power surge. If you can see the wiring around the unit, inspect it for any signs of burn or melted insulation. This could signify an electrical problem within the AC that needs a careful assessment by a skilled technician.

The next step is to investigate the circuit board. If the power outage changed any wiring, then the circuit board could be damaged. Inspect the circuit board for any burnt or melted wiring, and if possible, check for any visible stones or shorts. Use a voltmeter to test the voltages at the circuit board and make sure they match. Also examine the circuit breakers and fuses, in case one was overloaded by the power surge and needs to be replaced.

Lastly, check the condenser fan. Make sure the fan is running and that the fan blades are spinning freely. A faulty fan can cause the AC unit to overheat, resulting in an AC shutdown.

Dealing with the Damages Done

If the problem you are experiencing with your AC has been due to a power outage, then there are few steps you should take to mitigate any long-term damage. Firstly, hire a certified technician to repair any damaged parts or systems. This technician can inspect the AC unit and provide you with an estimate repair cost.

Once you have the repairs made, it is important to consider purchasing a surge protector device to protect your AC unit and electrical systems against any future power spikes. Additionally, scheduling regular maintenance procedures can ensure the AC avoids any long-term damages.

It is advisable to reach out to a reliable, local appliance repair company for more tailored advice. This company can identify and address any specific problems your AC unit may encounter after a power surge.

Wrapping Up

Power outages can cause an array of issues for air-conditioners and other electrical units in the home. Investigation is key to understanding why the AC is not running correctly and what caused the damage. The most effective way to tackle the AC problem is to hire a certified technician and have the unit inspected for damage. Additionally, the owner should consider purchasing a surge protector and scheduling regular maintenance services to help avoid potential damages in the future.

AC Not Working After Power Outage: Understanding and Preventing Issues

After a power outage, your air conditioning (AC) can stop working and require service or repair. Therefore, it is important to take preventive steps to avoid this issue. Below are manufacturer recommendations, local appliance companies’ or HVAC technician’s recommendations to help you reduce the risk of AC not working after a power outage.

Power Outage Preparedness

Before the power outage, you can take several steps to protect your AC in the event of power fluctuations or outages.

  • Make sure your AC’s power supply cord is plugged into a surge protector. Surge protectors can help to absorb any sudden electrical surges before they reach your AC’s circuitry.

  • Use a power protector for your whole home, such as a smart generator or a transfer switch. Smart generators turn on automatically when their internal sensors detect a sudden drop in power. The transfer switch automatically switches your AC’s power supply to a backup generator during an outage.

  • Consider installing a system that monitors your AC’s power supply and shuts it down during power outages.

Maintenance and Inspections

Regular maintenance and inspections of your AC system can greatly reduce the chances that your AC will not work after a power outage. Therefore, it is recommended to:

  • Have your AC system inspected and maintenance serviced regularly. During an inspection, your HVAC technician will check the components, such as the compressor, blower motor and other components and can identify and potential issue prior to a power outage.

A) A power outage can cause different types of damage to your air conditioner depending on the type, age and condition of your AC. If the power outage only lasts for a short time, you’ll likely notice your AC will come back on once the power is restored. However, if the power outage lasted for an extended period of time, causing your AC to be off for some time, you should call a local, reliable appliance repair service to check your AC for possible damage.

A) During a power outage your AC unit may be affected in a variety of ways. The surge of electricity that typically happens when the power is restored could cause a number of issues such as blown fuses, circuit breaker trips, and blown wires. If a power surge is too strong to be handled by your AC’s electrical system, the compressor may be damaged and won’t be able to turn back on. Also, the condenser fan may not turn back on after a power outage, causing the AC unit to run too hot and burn out the compressor.

Q) Can I Repair My AC Unit Myself if it Stopped Working After a Power Outage?

A) Air conditioners are complicated machines and require knowledge of the various parts and systems involved. If your AC isn’t working after a power outage and you’d like to repair it yourself, you may end up damaging the unit more and it could potentially be dangerous if you don’t have training and experience dealing with electricity and HVAC systems.
